1  461 141 CHANGES IN PERCEIVED STRESS AFTER YOGA, PHYSICAL THERAPY, AND EDUCATION INTERVENTIONS FOR CHRONIC LOW BACK PAIN: A SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: PERCEIVED STRESS AND MUSCULOSKELETAL PAIN ARE COMMON, ESPECIALLY IN LOW-INCOME POPULATIONS. STUDIES EVALUATING TREATMENTS TO REDUCE STRESS IN PATIENTS WITH CHRONIC PAIN ARE LACKING. WE AIMED TO QUANTIFY THE EFFECT OF TWO EVIDENCE-BASED INTERVENTIONS FOR CHRONIC LOW BACK PAIN (CLBP), YOGA AND PHYSICAL THERAPY (PT), ON PERCEIVED STRESS IN ADULTS WITH CLBP. METHODS: WE USED DATA FROM AN ASSESSOR-BLINDED, PARALLEL-GROUP RANDOMIZED CONTROLLED TRIAL, WHICH RECRUITED PREDOMINANTLY LOW-INCOME AND RACIALLY DIVERSE ADULTS WITH CLBP. PARTICIPANTS (N = 320) WERE RANDOMLY ASSIGNED TO 12 WEEKS OF YOGA, PT, OR BACK PAIN EDUCATION. WE COMPARED CHANGES IN THE 10-ITEM PERCEIVED STRESS SCALE (PSS-10) FROM BASELINE TO 12- AND 52-WEEK FOLLOW-UP AMONG YOGA AND PT PARTICIPANTS WITH THOSE RECEIVING EDUCATION. SUBANALYSES WERE CONDUCTED FOR PARTICIPANTS WITH ELEVATED PRE-INTERVENTION PERCEIVED STRESS (PSS-10 SCORE >/=17). WE CONDUCTED SENSITIVITY ANALYSES USING VARIOUS IMPUTATION METHODS TO ACCOUNT FOR POTENTIAL BIASES IN OUR ESTIMATES DUE TO MISSING DATA. RESULTS: AMONG 248 PARTICIPANTS (MEAN AGE = 46.4 YEARS, 80% NONWHITE) COMPLETING ALL THREE SURVEYS, YOGA AND PT SHOWED GREATER REDUCTIONS IN PSS-10 SCORES COMPARED WITH EDUCATION AT 12 WEEKS (MEAN BETWEEN-GROUP DIFFERENCE = -2.6, 95% CONFIDENCE INTERVAL [CI] = -4.5 TO -0.66, AND MEAN BETWEEN-GROUP DIFFERENCE = -2.4, 95% CI = -4.4 TO -0.48, RESPECTIVELY). THIS EFFECT WAS STRONGER AMONG PARTICIPANTS WITH ELEVATED PRE-INTERVENTION PERCEIVED STRESS. BETWEEN-GROUP EFFECTS HAD ATTENUATED BY 52 WEEKS. RESULTS WERE SIMILAR IN SENSITIVITY ANALYSES. CONCLUSIONS: YOGA AND PT WERE MORE EFFECTIVE THAN BACK PAIN EDUCATION FOR REDUCING PERCEIVED STRESS AMONG LOW-INCOME ADULTS WITH CLBP.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
2  460  73 CHANGES IN PAIN SELF-EFFICACY, COPING SKILLS, AND FEAR-AVOIDANCE BELIEFS IN A RANDOMIZED CONTROLLED TRIAL OF YOGA, PHYSICAL THERAPY, AND EDUCATION FOR CHRONIC LOW BACK PAIN. OBJECTIVE: WE EVALUATED EXERCISE INTERVENTIONS FOR COGNITIVE APPRAISAL OF CHRONIC LOW BACK PAIN (CLBP) IN AN UNDERSERVED POPULATION. METHODS: WE CONDUCTED A SECONDARY ANALYSIS OF THE BACK TO HEALTH TRIAL, SHOWING YOGA TO BE NONINFERIOR TO PHYSICAL THERAPY (PT) FOR PAIN AND FUNCTION OUTCOMES AMONG ADULTS WITH CLBP (N = 320) RECRUITED FROM PRIMARY CARE CLINICS WITH PREDOMINANTLY LOW-INCOME PATIENTS. PARTICIPANTS WERE RANDOMIZED TO 12 WEEKS OF YOGA, PT, OR EDUCATION. COGNITIVE APPRAISAL WAS ASSESSED WITH THE PAIN SELF-EFFICACY QUESTIONNAIRE (PSEQ), COPING STRATEGIES QUESTIONNAIRE (CSQ), AND FEAR-AVOIDANCE BELIEFS QUESTIONNAIRE (FABQ). USING MULTIPLE IMPUTATION AND LINEAR REGRESSION, WE ESTIMATED WITHIN- AND BETWEEN-GROUP CHANGES IN COGNITIVE APPRAISAL AT 12 AND 52 WEEKS, WITH BASELINE AND THE EDUCATION GROUP AS REFERENCES. RESULTS: PARTICIPANTS (MEAN AGE = 46 YEARS) WERE MAJORITY FEMALE (64%) AND MAJORITY BLACK (57%), AND 54% HAD AN ANNUAL HOUSEHOLD INCOME <$30,000. ALL THREE GROUPS SHOWED IMPROVEMENTS IN PSEQ (RANGE 0-60) AT 12 WEEKS (YOGA, MEAN DIFFERENCE [MD] = 7.0, 95% CONFIDENCE INTERVAL [CI]: 4.9, 9.0; PT, MD = 6.9, 95% CI: 4.7 TO 9.1; AND EDUCATION, MD = 3.4, 95% CI: 0.54 TO 6.3), WITH YOGA AND PT IMPROVEMENTS BEING CLINICALLY MEANINGFUL. AT 12 WEEKS, IMPROVEMENTS IN CATASTROPHIZING (CSQ, RANGE 0-36) WERE LARGEST IN THE YOGA AND PT GROUPS (MD = -3.0, 95% CI: -4.4 TO -1.6; MD = -2.7, 95% CI: -4.2 TO -1.2, RESPECTIVELY). CHANGES IN FABQ WERE SMALL. NO STATISTICALLY SIGNIFICANT BETWEEN-GROUP DIFFERENCES WERE OBSERVED ON PSEQ, CSQ, OR FABQ AT EITHER TIME POINT. MANY OF THE CHANGES OBSERVED AT 12 WEEKS WERE SUSTAINED AT 52 WEEKS. CONCLUSION: ALL THREE INTERVENTIONS WERE ASSOCIATED WITH IMPROVEMENTS IN SELF-EFFICACY AND CATASTROPHIZING AMONG LOW-INCOME, RACIALLY DIVERSE ADULTS WITH CLBP.

3 2852  54 YOGA, PHYSICAL THERAPY, OR EDUCATION FOR CHRONIC LOW BACK PAIN: A RANDOMIZED NONINFERIORITY TRIAL. BACKGROUND: YOGA IS EFFECTIVE FOR MILD TO MODERATE CHRONIC LOW BACK PAIN (CLBP), BUT ITS COMPARATIVE EFFECTIVENESS WITH PHYSICAL THERAPY (PT) IS UNKNOWN. MOREOVER, LITTLE IS KNOWN ABOUT YOGA'S EFFECTIVENESS IN UNDERSERVED PATIENTS WITH MORE SEVERE FUNCTIONAL DISABILITY AND PAIN. OBJECTIVE: TO DETERMINE WHETHER YOGA IS NONINFERIOR TO PT FOR CLBP. DESIGN: 12-WEEK, SINGLE-BLIND, 3-GROUP RANDOMIZED NONINFERIORITY TRIAL AND SUBSEQUENT 40-WEEK MAINTENANCE PHASE. (CLINICALTRIALS.GOV: NCT01343927). SETTING: ACADEMIC SAFETY-NET HOSPITAL AND 7 AFFILIATED COMMUNITY HEALTH CENTERS. PARTICIPANTS: 320 PREDOMINANTLY LOW-INCOME, RACIALLY DIVERSE ADULTS WITH NONSPECIFIC CLBP. INTERVENTION: PARTICIPANTS RECEIVED 12 WEEKLY YOGA CLASSES, 15 PT VISITS, OR AN EDUCATIONAL BOOK AND NEWSLETTERS. THE MAINTENANCE PHASE COMPARED YOGA DROP-IN CLASSES VERSUS HOME PRACTICE AND PT BOOSTER SESSIONS VERSUS HOME PRACTICE. MEASUREMENTS: PRIMARY OUTCOMES WERE BACK-RELATED FUNCTION, MEASURED BY THE ROLAND MORRIS DISABILITY QUESTIONNAIRE (RMDQ), AND PAIN, MEASURED BY AN 11-POINT SCALE, AT 12 WEEKS. PRESPECIFIED NONINFERIORITY MARGINS WERE 1.5 (RMDQ) AND 1.0 (PAIN). SECONDARY OUTCOMES INCLUDED PAIN MEDICATION USE, GLOBAL IMPROVEMENT, SATISFACTION WITH INTERVENTION, AND HEALTH-RELATED QUALITY OF LIFE. RESULTS: ONE-SIDED 95% LOWER CONFIDENCE LIMITS WERE 0.83 (RMDQ) AND 0.97 (PAIN), DEMONSTRATING NONINFERIORITY OF YOGA TO PT. HOWEVER, YOGA WAS NOT SUPERIOR TO EDUCATION FOR EITHER OUTCOME. YOGA AND PT WERE SIMILAR FOR MOST SECONDARY OUTCOMES. YOGA AND PT PARTICIPANTS WERE 21 AND 22 PERCENTAGE POINTS LESS LIKELY, RESPECTIVELY, THAN EDUCATION PARTICIPANTS TO USE PAIN MEDICATION AT 12 WEEKS. IMPROVEMENTS IN YOGA AND PT GROUPS WERE MAINTAINED AT 1 YEAR WITH NO DIFFERENCES BETWEEN MAINTENANCE STRATEGIES. FREQUENCY OF ADVERSE EVENTS, MOSTLY MILD SELF-LIMITED JOINT AND BACK PAIN, DID NOT DIFFER BETWEEN THE YOGA AND PT GROUPS. LIMITATIONS: PARTICIPANTS WERE NOT BLINDED TO TREATMENT ASSIGNMENT. THE PT GROUP HAD DISPROPORTIONATE LOSS TO FOLLOW-UP. CONCLUSION: A MANUALIZED YOGA PROGRAM FOR NONSPECIFIC CLBP WAS NONINFERIOR TO PT FOR FUNCTION AND PAIN.

4  518  52 COMPARING ONCE- VERSUS TWICE-WEEKLY YOGA CLASSES FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY LOW INCOME MINORITIES: A RANDOMIZED DOSING TRIAL. BACKGROUND. PREVIOUS STUDIES HAVE DEMONSTRATED THAT ONCE-WEEKLY YOGA CLASSES ARE EFFECTIVE FOR CHRONIC LOW BACK PAIN (CLBP) IN WHITE ADULTS WITH HIGH SOCIOECONOMIC STATUS. THE COMPARATIVE EFFECTIVENESS OF TWICE-WEEKLY CLASSES AND GENERALIZABILITY TO RACIALLY DIVERSE LOW INCOME POPULATIONS ARE UNKNOWN. METHODS. WE CONDUCTED A 12-WEEK RANDOMIZED, PARALLEL-GROUP, DOSING TRIAL FOR 95 ADULTS RECRUITED FROM AN URBAN SAFETY-NET HOSPITAL AND FIVE COMMUNITY HEALTH CENTERS COMPARING ONCE-WEEKLY (N = 49) VERSUS TWICE-WEEKLY (N = 46) STANDARDIZED YOGA CLASSES SUPPLEMENTED BY HOME PRACTICE. PRIMARY OUTCOMES WERE CHANGE FROM BASELINE TO 12 WEEKS IN PAIN (11-POINT SCALE) AND BACK-RELATED FUNCTION (23-POINT MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE). RESULTS. 82% OF PARTICIPANTS WERE NONWHITE; 77% HAD ANNUAL HOUSEHOLD INCOMES <$40,000. THE SAMPLE'S BASELINE MEAN PAIN INTENSITY [6.9 (SD 1.6)] AND FUNCTION [13.7 (SD 5.0)] REFLECTED MODERATE TO SEVERE BACK PAIN AND IMPAIRMENT. PAIN AND BACK-RELATED FUNCTION IMPROVED WITHIN BOTH GROUPS (P < 0.001). HOWEVER, THERE WERE NO DIFFERENCES BETWEEN ONCE-WEEKLY AND TWICE-WEEKLY GROUPS FOR PAIN REDUCTION [-2.1 (95% CI -2.9, -1.3) VERSUS -2.4 (95% CI -3.1, -1.8), P = 0.62] OR BACK-RELATED FUNCTION [-5.1 (95% CI -7.0, -3.2) VERSUS -4.9 (95% CI -6.5, -3.3), P = 0.83]. CONCLUSIONS. TWELVE WEEKS OF ONCE-WEEKLY OR TWICE-WEEKLY YOGA CLASSES WERE SIMILARLY EFFECTIVE FOR PREDOMINANTLY LOW INCOME MINORITY ADULTS WITH MODERATE TO SEVERE CHRONIC LOW BACK PAIN.

5 2851  67 YOGA, PHYSICAL THERAPY, AND BACK PAIN EDUCATION FOR SLEEP QUALITY IN LOW-INCOME RACIALLY DIVERSE ADULTS WITH CHRONIC LOW BACK PAIN: A SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: POOR SLEEP IS COMMON AMONG ADULTS WITH CHRONIC LOW BACK PAIN (CLBP), BUT THE INFLUENCE OF CLBP TREATMENTS, SUCH AS YOGA AND PHYSICAL THERAPY (PT), ON SLEEP QUALITY IS UNDER STUDIED. OBJECTIVE: EVALUATE THE EFFECTIVENESS OF YOGA AND PT FOR IMPROVING SLEEP QUALITY IN ADULTS WITH CLBP. DESIGN: SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. SETTING: ACADEMIC SAFETY-NET HOSPITAL AND 7 AFFILIATED COMMUNITY HEALTH CENTERS. PARTICIPANTS: A TOTAL OF 320 ADULTS WITH CLBP. INTERVENTION: TWELVE WEEKLY YOGA CLASSES, 1-ON-1 PT SESSIONS, OR AN EDUCATIONAL BOOK. MAIN MEASURES: SLEEP QUALITY WAS MEASURED USING THE PITTSBURGH SLEEP QUALITY INDEX (PSQI) GLOBAL SCORE (0-21) AT BASELINE, 12 WEEKS, AND 52 WEEKS. ADDITIONALLY, WE ALSO EVALUATED HOW THE PROPORTION OF PARTICIPANTS WHO ACHIEVED A CLINICALLY MEANINGFUL IMPROVEMENT IN SLEEP QUALITY (> 3-POINT REDUCTION IN PSQI) AT 12 WEEKS VARIED BY CHANGES IN PAIN AND PHYSICAL FUNCTION AT 6 WEEKS. KEY RESULTS: AMONG PARTICIPANTS (MEAN AGE = 46.0, 64% FEMALE, 82% NON-WHITE), NEARLY ALL (92%) REPORTED POOR SLEEP QUALITY (PSQI > 5) AT BASELINE. AT 12 WEEKS, MODEST IMPROVEMENTS IN SLEEP QUALITY WERE OBSERVED AMONG THE YOGA (PSQI MEAN DIFFERENCE [MD] = - 1.19, 95% CONFIDENCE INTERVAL [CI] - 1.82, - 0.55) AND PT (PSQI MD = - 0.91, 95% CI - 1.61, - 0.20) GROUPS. PARTICIPANTS WHO REPORTED A >/= 30% IMPROVEMENT IN PAIN OR PHYSICAL FUNCTION AT 6 WEEKS, COMPARED WITH THOSE WHO IMPROVED < 10%, WERE MORE LIKELY TO BE A SLEEP QUALITY RESPONDER AT 12 WEEKS (ODDS RATIO [OR] = 3.51, 95% CI 1.73, 7.11 AND OR = 2.16, 95% CI 1.18, 3.95, RESPECTIVELY). RESULTS WERE SIMILAR AT 52 WEEKS. CONCLUSION: IN A SAMPLE OF ADULTS WITH CLBP, VIRTUALLY ALL WITH POOR SLEEP QUALITY PRIOR TO INTERVENTION, MODEST BUT STATISTICALLY SIGNIFICANT IMPROVEMENTS IN SLEEP QUALITY WERE OBSERVED WITH BOTH YOGA AND PT. IRRESPECTIVE OF TREATMENT, CLINICALLY IMPORTANT SLEEP IMPROVEMENTS AT THE END OF THE INTERVENTION WERE ASSOCIATED WITH MID-INTERVENTION PAIN AND PHYSICAL FUNCTION IMPROVEMENTS.

6  430  67 CAN YOGA OR PHYSICAL THERAPY FOR CHRONIC LOW BACK PAIN IMPROVE DEPRESSION AND ANXIETY AMONG ADULTS FROM A RACIALLY DIVERSE, LOW-INCOME COMMUNITY? A SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: TO DETERMINE AND COMPARE THE EFFECT OF YOGA, PHYSICAL THERAPY (PT), AND EDUCATION ON DEPRESSIVE AND ANXIOUS SYMPTOMS IN PATIENTS WITH CHRONIC LOW BACK PAIN (CLBP). DESIGN: SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. SETTING: ACADEMIC SAFETY NET HOSPITAL AND 7 COMMUNITY HEALTH CENTERS. PARTICIPANTS: A TOTAL OF 320 ADULTS WITH CLBP. INTERVENTION: YOGA CLASSES, PT SESSIONS, OR AN EDUCATIONAL BOOK. OUTCOME MEASURE: DEPRESSION AND ANXIETY WERE MEASURED USING THE PATIENT HEALTH QUESTIONNAIRE AND GENERALIZED ANXIETY DISORDER 7-ITEM SCALE, RESPECTIVELY, AT BASELINE, 12, AND 52 WEEKS. WE IDENTIFIED BASELINE AND MIDTREATMENT (6-WK) FACTORS ASSOCIATED WITH CLINICALLY MEANINGFUL IMPROVEMENTS IN DEPRESSIVE (>/=3 POINTS) OR ANXIOUS (>/=2 POINTS) SYMPTOMS AT 12 WEEKS. RESULTS: PARTICIPANTS (FEMALE=64%; MEAN AGE, 46.0+/-10.7 YEARS) WERE PREDOMINANTLY NON-WHITE (82%), LOW-INCOME (<$30,000/YEAR, 59%), AND HAD NOT RECEIVED A COLLEGE DEGREE (71%). MOST PARTICIPANTS HAD MILD OR WORSE DEPRESSIVE (60%) AND ANXIOUS (50%) SYMPTOMS. AT 12 WEEKS, YOGA AND PT PARTICIPANTS EXPERIENCED MODEST WITHIN-GROUP IMPROVEMENTS IN DEPRESSIVE SYMPTOMS (MEAN DIFFERENCE [MD]=-1.23 [95% CI, -2.18 TO -0.28]; MD=-1.01 [95% CI, -2.05 TO -0.03], RESPECTIVELY). COMPARED WITH THE EDUCATION GROUP, 12-WEEK DIFFERENCES WERE NOT STATISTICALLY SIGNIFICANT, ALTHOUGH TRENDS FAVORED YOGA (MD=-0.71 [95% CI, -2.22 TO 0.81]) AND PT (MD= -0.32 [95% CI, -1.82 TO 1.18]). AT 12 WEEKS, IMPROVEMENTS IN ANXIOUS SYMPTOMS WERE ONLY FOUND IN PARTICIPANTS WHO HAD MILD OR MODERATE ANXIETY AT BASELINE. INDEPENDENT OF TREATMENT ARM, PARTICIPANTS WHO HAD 30% OR GREATER IMPROVEMENT IN PAIN OR FUNCTION MIDTREATMENT WERE MORE LIKELY TO HAVE A CLINICALLY MEANINGFUL IMPROVEMENT IN DEPRESSIVE SYMPTOMS (ODDS RATIO [OR], 1.82 [95% CI, 1.03-3.22]; OR, 1.79 [95% CI, 1.06-3.04], RESPECTIVELY). CONCLUSIONS: IN OUR SECONDARY ANALYSIS WE FOUND THAT DEPRESSION AND ANXIETY, COMMON IN THIS SAMPLE OF UNDERSERVED ADULTS WITH CLBP, MAY IMPROVE MODESTLY WITH PT AND YOGA. HOWEVER, EFFECTS WERE NOT SUPERIOR TO EDUCATION. IMPROVEMENTS IN PAIN AND FUNCTION ARE ASSOCIATED WITH A DECREASE IN DEPRESSIVE SYMPTOMS. MORE RESEARCH IS NEEDED TO OPTIMIZE THE INTEGRATION OF PHYSICAL AND PSYCHOLOGICAL WELL-BEING IN PT AND YOGA.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
7  638  54 DO PHYSICAL THERAPY AND YOGA IMPROVE PAIN AND DISABILITY THROUGH PSYCHOLOGICAL MECHANISMS? A CAUSAL MEDIATION ANALYSIS OF ADULTS WITH CHRONIC LOW BACK PAIN. OBJECTIVE: TO INVESTIGATE WHETHER INDIRECT EFFECTS VIA PSYCHOLOGICAL MECHANISMS EXPLAIN THE EFFECTS OF PHYSICAL THERAPY (PT) OR YOGA, VERSUS EDUCATION, ON BACK-RELATED OUTCOMES. DESIGN: MEDIATION ANALYSES USING DATA FROM A RANDOMIZED CONTROLLED TRIAL OF PT, YOGA, AND EDUCATION INTERVENTIONS FOR CHRONIC LOW BACK PAIN. METHODS: PRIMARY OUTCOMES WERE CHANGES IN BACK-RELATED PAIN ON THE 11-POINT NUMERICAL RATING SCALE AND DISABILITY ON THE MODIFIED 23-POINT ROLAND MORRIS DISABILITY QUESTIONNAIRE, MEASURED AT 52-WEEKS POST-RANDOMIZATION. HYPOTHESIZED MEDIATORS WERE 12-WEEK CHANGES IN PAIN SELF-EFFICACY, FEAR AVOIDANCE BELIEFS, DEPRESSION, ANXIETY, PERCEIVED STRESS, AND SLEEP QUALITY. WE USED CAUSAL MEDIATION ANALYSIS TO ESTIMATE THE TOTAL EFFECT, DIRECT EFFECT, INDIRECT EFFECT, AND PROPORTION MEDIATED. RESULTS: WE ANALYZED DATA FROM 230 ADULTS (MEAN AGE = 46.2 YEARS, 69.6% FEMALE, 79.6% NON-WHITE). IN THE PT VERSUS EDUCATION MODEL, WHEN THE MEDIATOR WAS PERCEIVED STRESS, THE TOTAL EFFECT ON DISABILITY WAS 2.6 POINTS (95% CI: 0.3, 4.9) AND DECOMPOSED INTO A DIRECT EFFECT OF 1.7 POINTS (95% CI: -0.4, 3.8) AND AN INDIRECT EFFECT 0.9 POINTS (95% CI: 0.1, 2.0; PROPORTION MEDIATED 34%). NO OTHER PSYCHOLOGICAL CONSTRUCT WAS A SIGNIFICANT MEDIATOR. CONCLUSION: IMPROVEMENTS IN PERCEIVED STRESS MEDIATED IMPROVEMENTS IN DISABILITY AFTER PT TREATMENT COMPARED TO EDUCATION. OTHER PSYCHOLOGICAL OUTCOMES DID NOT MEDIATE THE EFFECT OF YOGA OR PT ON PAIN OR DISABILITY OUTCOMES COMPARED TO EDUCATION. J ORTHOP SPORTS PHYS THER, EPUB 18 MAY 2022.

8  465  47 CHARACTERISTICS AND PREDICTORS OF SHORT-TERM OUTCOMES IN INDIVIDUALS SELF-SELECTING YOGA OR PHYSICAL THERAPY FOR TREATMENT OF CHRONIC LOW BACK PAIN. OBJECTIVE: TO COMPARE CLINICAL AND DEMOGRAPHIC CHARACTERISTICS OF INDIVIDUALS SELF-SELECTING YOGA OR PHYSICAL THERAPY (PT) FOR TREATMENT OF CHRONIC LOW BACK PAIN (CLBP) AND TO EXAMINE PREDICTORS OF SHORT-TERM PAIN AND FUNCTIONAL OUTCOMES. DESIGN: DESCRIPTIVE, LONGITUDINAL STUDY. SETTINGS: A HOSPITAL-BASED CLINIC THAT OFFERS MODIFIED INTEGRAL YOGA CLASSES FOR CLBP AND 2 OUTPATIENT PT CLINICS THAT OFFER EXERCISE-BASED PT. PARTICIPANTS: ADULTS (N=53) WITH CLBP>/=12 WEEKS: YOGA (N=27), PT (N=26). METHODS: YOGA PARTICIPANTS ATTENDED A 6-WEEK, ONCE WEEKLY, 2-HOUR YOGA CLASS. PT PARTICIPANTS UNDERWENT TWICE WEEKLY, 1-HOUR INDIVIDUALIZED PT. DATA WERE COLLECTED AT BASELINE AND AT 6 WEEKS. GROUPS WERE COMPARED BY USING CHI2 AND INDEPENDENT SAMPLES T-TESTS. HIERARCHICAL LINEAR REGRESSION WAS USED TO PREDICT TREATMENT OUTCOMES. MAIN OUTCOME MEASURES: DISABILITY (ROLAND MORRIS DISABILITY QUESTIONNAIRE), HEALTH STATUS (RAND SHORT FORM 36 HEALTH SURVEY 1.0), PAIN BOTHERSOMENESS (NUMERICAL RATING SCALE), BACK PAIN SELF-EFFICACY (BACK PAIN SELF-EFFICACY SCALE), AND TREATMENT SATISFACTION. RESULTS: AT BASELINE, YOGA PARTICIPANTS WERE SIGNIFICANTLY LESS DISABLED (P=.013), HAD HIGHER HEALTH STATUS (P=.023), GREATER PAIN SELF-EFFICACY (P=.012), AND LESS AVERAGE PAIN BOTHERSOMENESS (P=.001) COMPARED WITH PT PARTICIPANTS. AT 6 WEEKS, WHEN CONTROLLING FOR BASELINE GROUP DIFFERENCES, GREATER PAIN SELF-EFFICACY WAS THE STRONGEST PREDICTOR FOR REDUCED PAIN AND HIGHER FUNCTION FOR THE ENTIRE SAMPLE. A SIGNIFICANT GROUP INTERACTION BY BASELINE PAIN SELF-EFFICACY PREDICTED DISABILITY AT 6 WEEKS. PT PARTICIPANTS WITH LOW PAIN SELF-EFFICACY REPORTED SIGNIFICANTLY GREATER DISABILITY THAN THOSE WITH HIGH PAIN SELF-EFFICACY. YOGA PARTICIPANTS WITH LOW AND HIGH PAIN SELF-EFFICACY HAD SIMILAR DISABILITY OUTCOMES. CONCLUSION: THESE FINDINGS STRENGTHEN EVIDENCE THAT SELF-EFFICACY IS ASSOCIATED WITH CLBP OUTCOMES, ESPECIALLY IN INDIVIDUALS SELF-SELECTING PT. FURTHER RESEARCH TO EVALUATE OUTCOMES AFTER YOGA AND PT IN PARTICIPANTS WITH LOW PAIN SELF-EFFICACY IS NEEDED.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
9 2558  58 YOGA FOR CHRONIC LOW BACK PAIN IN A PREDOMINANTLY MINORITY POPULATION: A PILOT RANDOMIZED CONTROLLED TRIAL. BACKGROUND: SEVERAL STUDIES SUGGEST YOGA MAY BE EFFECTIVE FOR CHRONIC LOW BACK PAIN; HOWEVER, TRIALS TARGETING MINORITIES HAVE NOT BEEN CONDUCTED. PRIMARY STUDY OBJECTIVES: ASSESS THE FEASIBILITY OF STUDYING YOGA IN A PREDOMINANTLY MINORITY POPULATION WITH CHRONIC LOW BACK PAIN. COLLECT PRELIMINARY DATA TO PLAN A LARGER POWERED STUDY. STUDY DESIGN: PILOT RANDOMIZED CONTROLLED TRIAL. SETTING: TWO COMMUNITY HEALTH CENTERS IN A RACIALLY DIVERSE NEIGHBORHOOD OF BOSTON, MASSACHUSETTS. PARTICIPANTS: THIRTY ENGLISH-SPEAKING ADULTS (MEAN AGE 44 YEARS, 83% FEMALE, 83% RACIAL/ETHNIC MINORITIES; 48% WITH INCOMES < OR = $30,000) WITH MODERATE-TO-SEVERE CHRONIC LOW BACK PAIN. INTERVENTIONS: STANDARDIZED SERIES OF WEEKLY HATHA YOGA CLASSES FOR 12 WEEKS COMPARED TO A WAITLIST USUAL CARE CONTROL. OUTCOME MEASURES: FEASIBILITY MEASURED BY TIME TO COMPLETE ENROLLMENT, PROPORTION OF RACIAL/ETHNIC MINORITIES ENROLLED, RETENTION RATES, AND ADVERSE EVENTS. PRIMARY EFFICACY OUTCOMES WERE CHANGES FROM BASELINE TO 12 WEEKS IN PAIN SCORE (0=NO PAIN TO 10=WORST POSSIBLE PAIN) AND BACK-RELATED FUNCTION USING THE MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE (0-23 POINT SCALE, HIGHER SCORES REFLECT POORER FUNCTION). SECONDARY EFFICACY OUTCOMES WERE ANALGESIC USE, GLOBAL IMPROVEMENT, AND QUALITY OF LIFE (SF-36). RESULTS: RECRUITMENT TOOK 2 MONTHS. RETENTION RATES WERE 97% AT 12 WEEKS AND 77% AT 26 WEEKS. MEAN PAIN SCORES FOR YOGA DECREASED FROM BASELINE TO 12 WEEKS (6.7 TO 4.4) COMPARED TO USUAL CARE, WHICH DECREASED FROM 7.5 TO 7.1 (P=.02). MEAN ROLAND SCORES FOR YOGA DECREASED FROM 14.5 TO 8.2 COMPARED TO USUAL CARE, WHICH DECREASED FROM 16.1 TO 12.5 (P=.28). AT 12 WEEKS, YOGA COMPARED TO USUAL CARE PARTICIPANTS REPORTED LESS ANALGESIC USE (13% VS 73%, P=.003), LESS OPIATE USE (0% VS 33%, P=.04), AND GREATER OVERALL IMPROVEMENT (73% VS 27%, P=.03). THERE WERE NO DIFFERENCES IN SF-36 SCORES AND NO SERIOUS ADVERSE EVENTS. CONCLUSION: A YOGA STUDY INTERVENTION IN A PREDOMINANTLY MINORITY POPULATION WITH CHRONIC LOW BACK PAIN WAS MODERATELY FEASIBLE AND MAY BE MORE EFFECTIVE THAN USUAL CARE FOR REDUCING PAIN AND PAIN MEDICATION USE.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
10  521  45 COMPARING YOGA, EXERCISE, AND A SELF-CARE BOOK FOR CHRONIC LOW BACK PAIN: A RANDOMIZED, CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN IS A COMMON PROBLEM THAT HAS ONLY MODESTLY EFFECTIVE TREATMENT OPTIONS. OBJECTIVE: TO DETERMINE WHETHER YOGA IS MORE EFFECTIVE THAN CONVENTIONAL THERAPEUTIC EXERCISE OR A SELF-CARE BOOK FOR PATIENTS WITH CHRONIC LOW BACK PAIN. DESIGN: RANDOMIZED, CONTROLLED TRIAL. SETTING: A NONPROFIT, INTEGRATED HEALTH CARE SYSTEM. PATIENTS: 101 ADULTS WITH CHRONIC LOW BACK PAIN. INTERVENTION: 12-WEEK SESSIONS OF YOGA OR CONVENTIONAL THERAPEUTIC EXERCISE CLASSES OR A SELF-CARE BOOK. MEASUREMENTS: PRIMARY OUTCOMES WERE BACK-RELATED FUNCTIONAL STATUS (MODIFIED 24-POINT ROLAND DISABILITY SCALE) AND "BOTHERSOMENESS" OF PAIN (11-POINT NUMERICAL SCALE). THE PRIMARY TIME POINT WAS 12 WEEKS. CLINICALLY SIGNIFICANT CHANGE WAS CONSIDERED TO BE 2.5 POINTS ON THE FUNCTIONAL STATUS SCALE AND 1.5 POINTS ON THE BOTHERSOMENESS SCALE. SECONDARY OUTCOMES WERE DAYS OF RESTRICTED ACTIVITY, GENERAL HEALTH STATUS, AND MEDICATION USE. RESULTS: AFTER ADJUSTMENT FOR BASELINE VALUES, BACK-RELATED FUNCTION IN THE YOGA GROUP WAS SUPERIOR TO THE BOOK AND EXERCISE GROUPS AT 12 WEEKS (YOGA VS. BOOK: MEAN DIFFERENCE, -3.4 [95% CI, -5.1 TO - 1.6] [P < 0.001]; YOGA VS. EXERCISE: MEAN DIFFERENCE, -1.8 [CI, -3.5 TO - 0.1] [P = 0.034]). NO SIGNIFICANT DIFFERENCES IN SYMPTOM BOTHERSOMENESS WERE FOUND BETWEEN ANY 2 GROUPS AT 12 WEEKS; AT 26 WEEKS, THE YOGA GROUP WAS SUPERIOR TO THE BOOK GROUP WITH RESPECT TO THIS MEASURE (MEAN DIFFERENCE, -2.2 [CI, -3.2 TO - 1.2]; P < 0.001). AT 26 WEEKS, BACK-RELATED FUNCTION IN THE YOGA GROUP WAS SUPERIOR TO THE BOOK GROUP (MEAN DIFFERENCE, -3.6 [CI, -5.4 TO - 1.8]; P < 0.001). LIMITATIONS: PARTICIPANTS IN THIS STUDY WERE FOLLOWED FOR ONLY 26 WEEKS AFTER RANDOMIZATION. ONLY 1 INSTRUCTOR DELIVERED EACH INTERVENTION. CONCLUSIONS: YOGA WAS MORE EFFECTIVE THAN A SELF-CARE BOOK FOR IMPROVING FUNCTION AND REDUCING CHRONIC LOW BACK PAIN, AND THE BENEFITS PERSISTED FOR AT LEAST SEVERAL MONTHS.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
11 1699  51 PARTICIPANT CHARACTERISTICS ASSOCIATED WITH SYMPTOMATIC IMPROVEMENT FROM YOGA FOR CHRONIC LOW BACK PAIN. CONTEXT: STUDIES SUGGEST THAT YOGA IS EFFECTIVE FOR MODERATE TO SEVERE CHRONIC LOW BACK PAIN (CLBP) IN DIVERSE PREDOMINANTLY LOWER SOCIOECONOMIC STATUS POPULATIONS. HOWEVER, LITTLE IS KNOWN ABOUT FACTORS ASSOCIATED WITH BENEFIT FROM THE YOGA INTERVENTION. OBJECTIVE: IDENTIFY FACTORS AT BASELINE INDEPENDENTLY ASSOCIATED WITH GREATER EFFICACY AMONG PARTICIPANTS IN A STUDY OF YOGA FOR CLBP. DESIGN: FROM SEPTEMBER-DECEMBER 2011, A 12-WEEK RANDOMIZED DOSING TRIAL WAS CONDUCTED COMPARING WEEKLY VS. TWICE-WEEKLY 75-MINUTE HATHA YOGA CLASSES FOR 95 PREDOMINANTLY LOW-INCOME MINORITY ADULTS WITH NONSPECIFIC CLBP. PARTICIPANT CHARACTERISTICS COLLECTED AT BASELINE WERE USED TO DETERMINE FACTORS BEYOND TREATMENT ASSIGNMENT (REPORTED IN THE INITIAL STUDY) THAT PREDICTED OUTCOME. WE USED BIVARIATE TESTING TO IDENTIFY BASELINE CHARACTERISTICS ASSOCIATED WITH IMPROVEMENT IN FUNCTION AND PAIN, AND INCLUDED SELECT FACTORS IN A MULTIVARIATE LINEAR REGRESSION. SETTING: RECRUITMENT AND CLASSES OCCURRED IN AN ACADEMIC SAFETY-NET HOSPITAL AND FIVE AFFILIATED COMMUNITY HEALTH CENTERS IN BOSTON, MASSACHUSETTS. PARTICIPANTS: NINETY-FIVE ADULTS WITH NONSPECIFIC CLBP, AGES RANGING FROM 20-64 (MEAN 48) YEARS; 72 WOMEN AND 23 MEN. OUTCOME MEASURES: PRIMARY OUTCOMES WERE CHANGES IN BACK-RELATED FUNCTION (MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE, RMDQ; 0-23) AND MEAN LOW BACK PAIN INTENSITY (0-10) IN THE PREVIOUS WEEK, FROM BASELINE TO WEEK 12. RESULTS: ADJUSTING FOR GROUP ASSIGNMENT, BASELINE RMDQ, AGE, AND GENDER, FOREIGN NATIONALITY AND LOWER BASELINE SF36 PHYSICAL COMPONENT SCORE (PCS) WERE INDEPENDENTLY ASSOCIATED WITH IMPROVEMENT IN RMDQ. GREATER THAN HIGH SCHOOL EDUCATION LEVEL, CLBP LESS THAN 1 YEAR, AND LOWER BASELINE SF36 PCS WERE INDEPENDENTLY ASSOCIATED WITH IMPROVEMENT IN PAIN INTENSITY. OTHER DEMOGRAPHICS INCLUDING RACE, INCOME, GENDER, BMI, AND USE OF PAIN MEDICATIONS WERE NOT ASSOCIATED WITH EITHER OUTCOME. CONCLUSIONS: POOR PHYSICAL HEALTH AT BASELINE IS ASSOCIATED WITH GREATER IMPROVEMENT FROM YOGA IN BACK-RELATED FUNCTION AND PAIN. RACE, INCOME, AND BODY MASS INDEX DO NOT AFFECT THE POTENTIAL FOR A PERSON WITH LOW BACK PAIN TO EXPERIENCE BENEFIT FROM YOGA.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
12  193  45 A RANDOMIZED TRIAL COMPARING YOGA, STRETCHING, AND A SELF-CARE BOOK FOR CHRONIC LOW BACK PAIN. BACKGROUND: CHRONIC LOW BACK PAIN IS A COMMON PROBLEM LACKING HIGHLY EFFECTIVE TREATMENT OPTIONS. SMALL TRIALS SUGGEST THAT YOGA MAY HAVE BENEFITS FOR THIS CONDITION. THIS TRIAL WAS DESIGNED TO DETERMINE WHETHER YOGA IS MORE EFFECTIVE THAN CONVENTIONAL STRETCHING EXERCISES OR A SELF-CARE BOOK FOR PRIMARY CARE PATIENTS WITH CHRONIC LOW BACK PAIN. METHODS: A TOTAL OF 228 ADULTS WITH CHRONIC LOW BACK PAIN WERE RANDOMIZED TO 12 WEEKLY CLASSES OF YOGA (92 PATIENTS) OR CONVENTIONAL STRETCHING EXERCISES (91 PATIENTS) OR A SELF-CARE BOOK (45 PATIENTS). BACK-RELATED FUNCTIONAL STATUS (MODIFIED ROLAND DISABILITY QUESTIONNAIRE, A 23-POINT SCALE) AND BOTHERSOMENESS OF PAIN (AN 11-POINT NUMERICAL SCALE) AT 12 WEEKS WERE THE PRIMARY OUTCOMES. OUTCOMES WERE ASSESSED AT BASELINE, 6, 12, AND 26 WEEKS BY INTERVIEWERS UNAWARE OF TREATMENT GROUP. RESULTS: AFTER ADJUSTMENT FOR BASELINE VALUES, 12-WEEK OUTCOMES FOR THE YOGA GROUP WERE SUPERIOR TO THOSE FOR THE SELF-CARE GROUP (MEAN DIFFERENCE FOR FUNCTION, -2.5 [95% CI, -3.7 TO -1.3]; P < .001; MEAN DIFFERENCE FOR SYMPTOMS, -1.1 [95% CI, -1.7 TO -0.4]; P < .001). AT 26 WEEKS, FUNCTION FOR THE YOGA GROUP REMAINED SUPERIOR (MEAN DIFFERENCE, -1.8 [95% CI, -3.1 TO -0.5]; P < .001). YOGA WAS NOT SUPERIOR TO CONVENTIONAL STRETCHING EXERCISES AT ANY TIME POINT. CONCLUSION: YOGA CLASSES WERE MORE EFFECTIVE THAN A SELF-CARE BOOK, BUT NOT MORE EFFECTIVE THAN STRETCHING CLASSES, IN IMPROVING FUNCTION AND REDUCING SYMPTOMS DUE TO CHRONIC LOW BACK PAIN, WITH BENEFITS LASTING AT LEAST SEVERAL MONTHS.

13 1133  43 EFFICACY OF YOGA FOR VASOMOTOR SYMPTOMS: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: THIS STUDY AIMS TO DETERMINE THE EFFICACY OF YOGA IN ALLEVIATING VASOMOTOR SYMPTOMS (VMS) FREQUENCY AND BOTHER. METHODS: THIS STUDY WAS A THREE-BY-TWO FACTORIAL, RANDOMIZED CONTROLLED TRIAL. ELIGIBLE WOMEN WERE RANDOMIZED TO YOGA (N = 107), EXERCISE (N = 106), OR USUAL ACTIVITY (N = 142), AND WERE SIMULTANEOUSLY RANDOMIZED TO A DOUBLE-BLIND COMPARISON OF OMEGA-3 FATTY ACID (N = 177) OR PLACEBO (N = 178) CAPSULES. YOGA INTERVENTION CONSISTED OF 12 WEEKLY 90-MINUTE YOGA CLASSES WITH DAILY HOME PRACTICE. PRIMARY OUTCOMES WERE VMS FREQUENCY AND BOTHER ASSESSED BY DAILY DIARIES AT BASELINE, 6 WEEKS, AND 12 WEEKS. SECONDARY OUTCOMES INCLUDED INSOMNIA SYMPTOMS (INSOMNIA SEVERITY INDEX) AT BASELINE AND 12 WEEKS. RESULTS: AMONG 249 RANDOMIZED WOMEN, 237 (95%) COMPLETED 12-WEEK ASSESSMENTS. THE MEAN BASELINE VMS FREQUENCY WAS 7.4 PER DAY (95% CI, 6.6 TO 8.1) IN THE YOGA GROUP AND 8.0 PER DAY (95% CI, 7.3 TO 8.7) IN THE USUAL ACTIVITY GROUP. INTENT-TO-TREAT ANALYSES INCLUDED ALL PARTICIPANTS WITH RESPONSE DATA (N = 237). THERE WAS NO DIFFERENCE BETWEEN INTERVENTION GROUPS IN THE CHANGE IN VMS FREQUENCY FROM BASELINE TO 6 AND 12 WEEKS (MEAN DIFFERENCE [YOGA--USUAL ACTIVITY] FROM BASELINE AT 6 WK, -0.3 [95% CI, -1.1 TO 0.5]; MEAN DIFFERENCE [YOGA--USUAL ACTIVITY] FROM BASELINE AT 12 WK, -0.3 [95% CI, -1.2 TO 0.6]; P = 0.119 ACROSS BOTH TIME POINTS). RESULTS WERE SIMILAR FOR VMS BOTHER. AT WEEK 12, YOGA WAS ASSOCIATED WITH AN IMPROVEMENT IN INSOMNIA SYMPTOMS (MEAN DIFFERENCE [YOGA - USUAL ACTIVITY] IN THE CHANGE IN INSOMNIA SEVERITY INDEX, 1.3 [95% CI, -2.5 TO -0.1]; P = 0.007). CONCLUSIONS: AMONG HEALTHY WOMEN, 12 WEEKS OF YOGA CLASS PLUS HOME PRACTICE, COMPARED WITH USUAL ACTIVITY, DO NOT IMPROVE VMS FREQUENCY OR BOTHER BUT REDUCE INSOMNIA SYMPTOMS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
14 2560  55 YOGA FOR CHRONIC LOW BACK PAIN: A RANDOMIZED TRIAL. BACKGROUND: PREVIOUS STUDIES INDICATE THAT YOGA MAY BE AN EFFECTIVE TREATMENT FOR CHRONIC OR RECURRENT LOW BACK PAIN. OBJECTIVE: TO COMPARE THE EFFECTIVENESS OF YOGA AND USUAL CARE FOR CHRONIC OR RECURRENT LOW BACK PAIN. DESIGN: PARALLEL-GROUP, RANDOMIZED, CONTROLLED TRIAL USING COMPUTER-GENERATED RANDOMIZATION CONDUCTED FROM APRIL 2007 TO MARCH 2010. OUTCOMES WERE ASSESSED BY POSTAL QUESTIONNAIRE. (INTERNATIONAL STANDARD RANDOMISED CONTROLLED TRIAL NUMBER REGISTER: ISRCTN 81079604) SETTING: 13 NON-NATIONAL HEALTH SERVICE PREMISES IN THE UNITED KINGDOM. PATIENTS: 313 ADULTS WITH CHRONIC OR RECURRENT LOW BACK PAIN. INTERVENTION: YOGA (N = 156) OR USUAL CARE (N = 157). ALL PARTICIPANTS RECEIVED A BACK PAIN EDUCATION BOOKLET. THE INTERVENTION GROUP WAS OFFERED A 12-CLASS, GRADUALLY PROGRESSING YOGA PROGRAM DELIVERED BY 12 TEACHERS OVER 3 MONTHS. MEASUREMENTS: SCORES ON THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE (RMDQ) AT 3 (PRIMARY OUTCOME), 6, AND 12 (SECONDARY OUTCOMES) MONTHS; PAIN, PAIN SELF-EFFICACY, AND GENERAL HEALTH MEASURES AT 3, 6, AND 12 MONTHS (SECONDARY OUTCOMES). RESULTS: 93 (60%) PATIENTS OFFERED YOGA ATTENDED AT LEAST 3 OF THE FIRST 6 SESSIONS AND AT LEAST 3 OTHER SESSIONS. THE YOGA GROUP HAD BETTER BACK FUNCTION AT 3, 6, AND 12 MONTHS THAN THE USUAL CARE GROUP. THE ADJUSTED MEAN RMDQ SCORE WAS 2.17 POINTS (95% CI, 1.03 TO 3.31 POINTS) LOWER IN THE YOGA GROUP AT 3 MONTHS, 1.48 POINTS (CI, 0.33 TO 2.62 POINTS) LOWER AT 6 MONTHS, AND 1.57 POINTS (CI, 0.42 TO 2.71 POINTS) LOWER AT 12 MONTHS. THE YOGA AND USUAL CARE GROUPS HAD SIMILAR BACK PAIN AND GENERAL HEALTH SCORES AT 3, 6, AND 12 MONTHS, AND THE YOGA GROUP HAD HIGHER PAIN SELF-EFFICACY SCORES AT 3 AND 6 MONTHS BUT NOT AT 12 MONTHS. TWO OF THE 157 USUAL CARE PARTICIPANTS AND 12 OF THE 156 YOGA PARTICIPANTS REPORTED ADVERSE EVENTS, MOSTLY INCREASED PAIN. LIMITATION: THERE WERE MISSING DATA FOR THE PRIMARY OUTCOME (YOGA GROUP, N = 21; USUAL CARE GROUP, N = 18) AND DIFFERENTIAL MISSING DATA (MORE IN THE YOGA GROUP) FOR SECONDARY OUTCOMES. CONCLUSION: OFFERING A 12-WEEK YOGA PROGRAM TO ADULTS WITH CHRONIC OR RECURRENT LOW BACK PAIN LED TO GREATER IMPROVEMENTS IN BACK FUNCTION THAN DID USUAL CARE.

15 2831  47 YOGA VS. PHYSICAL THERAPY VS. EDUCATION FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY MINORITY POPULATIONS: STUDY PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN CAUSES SUBSTANTIAL MORBIDITY AND COST TO SOCIETY WHILE DISPROPORTIONATELY IMPACTING LOW-INCOME AND MINORITY ADULTS. SEVERAL RANDOMIZED CONTROLLED TRIALS SHOW YOGA IS AN EFFECTIVE TREATMENT. HOWEVER, THE COMPARATIVE EFFECTIVENESS OF YOGA AND PHYSICAL THERAPY, A COMMON MAINSTREAM TREATMENT FOR CHRONIC LOW BACK PAIN, IS UNKNOWN. METHODS/DESIGN: THIS IS A RANDOMIZED CONTROLLED TRIAL FOR 320 PREDOMINANTLY LOW-INCOME MINORITY ADULTS WITH CHRONIC LOW BACK PAIN, COMPARING YOGA, PHYSICAL THERAPY, AND EDUCATION. INCLUSION CRITERIA ARE ADULTS 18-64 YEARS OLD WITH NON-SPECIFIC LOW BACK PAIN LASTING >/= 12 WEEKS AND A SELF-REPORTED AVERAGE PAIN INTENSITY OF >/= 4 ON A 0-10 SCALE. RECRUITMENT TAKES PLACE AT BOSTON MEDICAL CENTER, AN URBAN ACADEMIC SAFETY-NET HOSPITAL AND SEVEN FEDERALLY QUALIFIED COMMUNITY HEALTH CENTERS LOCATED IN DIVERSE NEIGHBORHOODS. THE 52-WEEK STUDY HAS AN INITIAL 12-WEEK TREATMENT PHASE WHERE PARTICIPANTS ARE RANDOMIZED IN A 2:2:1 RATIO INTO I) A STANDARDIZED WEEKLY HATHA YOGA CLASS SUPPLEMENTED BY HOME PRACTICE; II) A STANDARDIZED EVIDENCE-BASED EXERCISE THERAPY PROTOCOL ADAPTED FROM THE TREATMENT BASED CLASSIFICATION METHOD, INDIVIDUALLY DELIVERED BY A PHYSICAL THERAPIST AND SUPPLEMENTED BY HOME PRACTICE; AND III) EDUCATION DELIVERED THROUGH A SELF-CARE BOOK. CO-PRIMARY OUTCOME MEASURES ARE 12-WEEK PAIN INTENSITY MEASURED ON AN 11-POINT NUMERICAL RATING SCALE AND BACK-SPECIFIC FUNCTION MEASURED USING THE MODIFIED ROLAND MORRIS DISABILITY QUESTIONNAIRE. IN THE SUBSEQUENT 40-WEEK MAINTENANCE PHASE, YOGA PARTICIPANTS ARE RE-RANDOMIZED IN A 1:1 RATIO TO EITHER STRUCTURED MAINTENANCE YOGA CLASSES OR HOME PRACTICE ONLY. PHYSICAL THERAPY PARTICIPANTS ARE SIMILARLY RE-RANDOMIZED TO EITHER FIVE BOOSTER SESSIONS OR HOME PRACTICE ONLY. EDUCATION PARTICIPANTS CONTINUE TO FOLLOW RECOMMENDATIONS OF EDUCATIONAL MATERIALS.

16 2820  63 YOGA TREATMENT FOR CHRONIC NON-SPECIFIC LOW BACK PAIN (2017). WIELAND LS, SKOETZ N, PILKINGTON K, VEMPATI R, DADAMO CR, BERMAN BM. YOGA TREATMENT FOR CHRONIC NON-SPECIFIC LOW BACK PAIN.COCHRANE DATABASE SYST REV2017, ISSUE 1. ART. NO.: CD010671. DOI: 10.1002/14651858.CD010671.PUB2. BACKGROUND: NON-SPECIFIC LOW BACK PAIN IS A COMMON, POTENTIALLY DISABLING CONDITION USUALLY TREATED WITH SELF-CARE AND NON-PRESCRIPTION MEDICATION. FOR CHRONIC LOW BACK PAIN, CURRENT GUIDELINES STATE THAT EXERCISE THERAPY MAY BE BENEFICIAL. YOGA IS A MIND-BODY EXERCISE SOMETIMES USED FOR NON-SPECIFIC LOW BACK PAIN. OBJECTIVES: TO ASSESS THE EFFECTS OF YOGA FOR TREATING CHRONIC NON-SPECIFIC LOW BACK PAIN, COMPARED TO NO SPECIFIC TREATMENT, A MINIMAL INTERVENTION (E.G., EDUCATION), OR ANOTHER ACTIVE TREATMENT, WITH A FOCUS ON PAIN, FUNCTION, AND ADVERSE EVENTS. SEARCH METHODS: WE SEARCHED CENTRAL, MEDLINE, EMBASE, FIVE OTHER DATABASES, AND FOUR TRIALS REGISTERS TO 11 MARCH 2016 WITHOUT RESTRICTION OF LANGUAGE OR PUBLICATION STATUS. WE SCREENED REFERENCE LISTS AND CONTACTED EXPERTS IN THE FIELD TO IDENTIFY ADDITIONAL STUDIES. SELECTION CRITERIA: WE INCLUDED RANDOMIZED CONTROLLED TRIALS OF YOGA TREATMENT IN PEOPLE WITH CHRONIC NON-SPECIFIC LOW BACK PAIN. WE INCLUDED STUDIES COMPARING YOGA TO ANY OTHER INTERVENTION OR TO NO INTERVENTION. WE ALSO INCLUDED STUDIES COMPARING YOGA AS AN ADJUNCT TO OTHER THERAPIES, VERSUS THOSE OTHER THERAPIES ALONE. DATA COLLECTION AND ANALYSIS: TWO AUTHORS INDEPENDENTLY SCREENED AND SELECTED STUDIES, EXTRACTED OUTCOME DATA, AND ASSESSED RISK OF BIAS. WE CONTACTED STUDY AUTHORS TO OBTAIN MISSING OR UNCLEAR INFORMATION. WE EVALUATED THE OVERALL CERTAINTY OF EVIDENCE USING THE GRADE APPROACH. MAIN RESULTS: WE INCLUDED 12 TRIALS (1080 PARTICIPANTS) CARRIED OUT IN THE USA (SEVEN TRIALS), INDIA (THREE TRIALS), AND THE UK (TWO TRIALS). STUDIES WERE UNFUNDED (ONE TRIAL), FUNDED BY A YOGA INSTITUTION (ONE TRIAL), FUNDED BY NON-PROFIT OR GOVERNMENT SOURCES (SEVEN TRIALS), OR DID NOT REPORT ON FUNDING (THREE TRIALS). MOST TRIALS USED IYENGAR, HATHA, OR VINIYOGA FORMS OF YOGA. THE TRIALS COMPARED YOGA TO NO INTERVENTION OR A NON-EXERCISE INTERVENTION SUCH AS EDUCATION (SEVEN TRIALS), AN EXERCISE INTERVENTION (THREE TRIALS), OR BOTH EXERCISE AND NON-EXERCISE INTERVENTIONS (TWO TRIALS). ALL TRIALS WERE AT HIGH RISK OF PERFORMANCE AND DETECTION BIAS BECAUSE PARTICIPANTS AND PROVIDERS WERE NOT BLINDED TO TREATMENT ASSIGNMENT, AND OUTCOMES WERE SELF-ASSESSED. THEREFORE, WE DOWNGRADED ALL OUTCOMES TO "MODERATE" CERTAINTY EVIDENCE BECAUSE OF RISK OF BIAS, AND WHEN THERE WAS ADDITIONAL SERIOUS RISK OF BIAS, UNEXPLAINED HETEROGENEITY BETWEEN STUDIES, OR THE ANALYSES WERE IMPRECISE, WE DOWNGRADED THE CERTAINTY OF THE EVIDENCE FURTHER. FOR YOGA COMPARED TO NON-EXERCISE CONTROLS (9 TRIALS; 810 PARTICIPANTS), THERE WAS LOW-CERTAINTY EVIDENCE THAT YOGA PRODUCED SMALL TO MODERATE IMPROVEMENTS IN BACK-RELATED FUNCTION AT THREE TO FOUR MONTHS [STANDARDIZED MEAN DIFFERENCE (SMD) = -0.40, 95% CI: -0.66 TO -0.14; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MEAN DIFFERENCE (MD) = -2.18, 95% CI: -3.60 TO -0.76], MODERATE-CERTAINTY EVIDENCE FOR SMALL TO MODERATE IMPROVEMENTS AT SIX MONTHS (SMD = -0.44, 95% CI: -0.66 TO -0.22; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD = -2.15, 95% CI: -3.23 TO -1.08), AND LOW-CERTAINTY EVIDENCE FOR SMALL IMPROVEMENTS AT 12 MONTHS (SMD = -0.26, 95% CI: -0.46 TO -0.05; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD = -1.36, 95% CI: -2.41 TO -0.26). ON A 0-100 SCALE THERE WAS VERY LOW- TO MODERATE-CERTAINTY EVIDENCE THAT YOGA WAS SLIGHTLY BETTER FOR PAIN AT THREE TO FOUR MONTHS (MD = -4.55, 95% CI: -7.04 TO -2.06), SIX MONTHS (MD = -7.81, 95% CI: -13.37 TO -2.25), AND 12 MONTHS (MD = -5.40, 95% CI: -14.50 TO -3.70); HOWEVER, WE PRE-DEFINED CLINICALLY SIGNIFICANT CHANGES IN PAIN AS 15 POINTS OR GREATER AND THIS THRESHOLD WAS NOT MET. BASED ON INFORMATION FROM SIX TRIALS, THERE WAS MODERATE-CERTAINTY EVIDENCE THAT THE RISK OF ADVERSE EVENTS, PRIMARILY INCREASED BACK PAIN, WAS HIGHER IN YOGA THAN IN NON-EXERCISE CONTROLS [RISK DIFFERENCE (RD) = 5%, 95% CI: 2-8%]. FOR YOGA COMPARED TO NON-YOGA EXERCISE CONTROLS (4 TRIALS; 394 PARTICIPANTS), THERE WAS VERY-LOW-CERTAINTY EVIDENCE FOR LITTLE OR NO DIFFERENCE IN BACK-RELATED FUNCTION AT THREE MONTHS (SMD = -0.22, 95% CI: -0.65 TO 0.20; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD = -0.99, 95% CI: -2.87 TO 0.90) AND SIX MONTHS (SMD = -0.20, 95% CI: -0.59 TO 0.19; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD = -0.90, 95% CI: -2.61 TO 0.81), AND NO INFORMATION ON BACK-RELATED FUNCTION AFTER SIX MONTHS. THERE WAS VERY LOW-CERTAINTY EVIDENCE FOR LOWER PAIN ON A 0-100 SCALE AT SEVEN MONTHS (MD = -20.40, 95% CI: -25.48 TO -15.32), AND NO INFORMATION ON PAIN AT THREE MONTHS OR AFTER SEVEN MONTHS. BASED ON INFORMATION FROM THREE TRIALS, THERE WAS LOW-CERTAINTY EVIDENCE FOR NO DIFFERENCE IN THE RISK OF ADVERSE EVENTS BETWEEN YOGA AND NON-YOGA EXERCISE CONTROLS (RD = 1%, 95% CI: -4% TO 6%). FOR YOGA ADDED TO EXERCISE COMPARED TO EXERCISE ALONE (1 TRIAL; 24 PARTICIPANTS), THERE WAS VERY-LOW-CERTAINTY EVIDENCE FOR LITTLE OR NO DIFFERENCE AT 10 WEEKS IN BACK-RELATED FUNCTION (SMD = -0.60, 95% CI: -1.42 TO 0.22; CORRESPONDING TO A CHANGE IN THE OSWESTRY DISABILITY INDEX OF MD = -17.05, 95% CI: -22.96 TO 11.14) OR PAIN ON A 0-100 SCALE (MD = -3.20, 95% CI: -13.76 TO 7.36). THERE WAS NO INFORMATION ON OUTCOMES AT OTHER TIME POINTS. THERE WAS NO INFORMATION ON ADVERSE EVENTS. STUDIES PROVIDED LIMITED EVIDENCE ON RISK OF CLINICAL IMPROVEMENT, MEASURES OF QUALITY OF LIFE, AND DEPRESSION. THERE WAS NO EVIDENCE ON WORK-RELATED DISABILITY.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
17   34  42 A 12-WEEK IYENGAR YOGA PROGRAM IMPROVED BALANCE AND MOBILITY IN OLDER COMMUNITY-DWELLING PEOPLE: A PILOT RANDOMIZED CONTROLLED TRIAL. BACKGROUND: EXERCISE THAT CHALLENGES BALANCE CAN IMPROVE MOBILITY AND PREVENT FALLS IN OLDER ADULTS. YOGA AS A PHYSICAL ACTIVITY OPTION FOR OLDER ADULTS IS NOT WELL STUDIED. THIS TRIAL EVALUATED THE FEASIBILITY AND EFFECT OF A 12-WEEK IYENGAR YOGA PROGRAM ON BALANCE AND MOBILITY IN OLDER PEOPLE. METHODS: WE CONDUCTED A BLINDED, PILOT RANDOMIZED CONTROLLED TRIAL WITH INTENTION-TO-TREAT ANALYSIS. PARTICIPANTS WERE 54 COMMUNITY DWELLERS (MEAN AGE 68 YEARS, SD 7.1) NOT CURRENTLY PARTICIPATING IN YOGA OR TAI CHI. THE INTERVENTION GROUP (N = 27) PARTICIPATED IN A 12-WEEK, TWICE-WEEKLY YOGA PROGRAM FOCUSED ON STANDING POSTURES AND RECEIVED A FALL PREVENTION EDUCATION BOOKLET. THE CONTROL GROUP (N = 27) RECEIVED THE EDUCATION BOOKLET ONLY. PRIMARY OUTCOME WAS STANDING BALANCE COMPONENT OF THE SHORT PHYSICAL PERFORMANCE BATTERY WITH ADDITION OF ONE-LEGGED STANCE TIME (STANDING BALANCE). SECONDARY OUTCOMES WERE THE TIMED SIT-TO-STAND TEST, TIMED 4-M WALK, ONE-LEGGED STAND WITH EYES CLOSED, AND SHORT FALLS EFFICACY SCALE-INTERNATIONAL. FEASIBILITY WAS MEASURED BY RECORDING CLASS ATTENDANCE AND ADVERSE EVENTS. RESULTS: FIFTY-TWO PARTICIPANTS COMPLETED FOLLOW-UP ASSESSMENTS. THE INTERVENTION GROUP SIGNIFICANTLY IMPROVED COMPARED WITH CONTROL GROUP ON STANDING BALANCE (MEAN DIFFERENCE = 1.52 SECONDS, 95% CI 0.10-2.96, P = .04), SIT-TO-STAND TEST (MEAN DIFFERENCE = -3.43 SECONDS, 95% CI -5.23 TO -1.64, P < .001), 4-M WALK (MEAN DIFFERENCE = -0.50 SECONDS, 95% CI -0.72 TO -0.28, P < .001), AND ONE-LEGGED STAND WITH EYES CLOSED (MEAN DIFFERENCE = 1.93 SECONDS, 95% CI 0.40-3.46, P = .02). AVERAGE CLASS ATTENDANCE WAS 20 OF 24 CLASSES (83%). NO SERIOUS ADVERSE EVENTS OCCURRED. CONCLUSIONS: THIS TRIAL DEMONSTRATES THE BALANCE AND MOBILITY-RELATED BENEFITS AND FEASIBILITY OF IYENGAR YOGA FOR OLDER PEOPLE. THE FALL PREVENTION EFFECT OF IYENGAR YOGA WARRANTS FURTHER INVESTIGATION.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
18 2374  59 WHICH CHRONIC LOW BACK PAIN PATIENTS RESPOND FAVORABLY TO YOGA, PHYSICAL THERAPY, AND A SELF-CARE BOOK? RESPONDER ANALYSES FROM A RANDOMIZED CONTROLLED TRIAL. PURPOSE: TO IDENTIFY BASELINE CHARACTERISTICS OF ADULTS WITH CHRONIC LOW BACK PAIN (CLBP) THAT PREDICT RESPONSE (I.E., A CLINICALLY IMPORTANT IMPROVEMENT) AND/OR MODIFY TREATMENT EFFECT ACROSS THREE NONPHARMACOLOGIC INTERVENTIONS. DESIGN: SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. SETTING: ACADEMIC SAFETY NET HOSPITAL AND SEVEN FEDERALLY QUALIFIED COMMUNITY HEALTH CENTERS. SUBJECTS: ADULTS WITH CLBP (N = 299). METHODS: WE REPORT PATIENT CHARACTERISTICS THAT WERE PREDICTORS OF RESPONSE AND/OR MODIFIED TREATMENT EFFECT ACROSS THREE 12-WEEK TREATMENTS: YOGA, PHYSICAL THERAPY [PT], AND A SELF-CARE BOOK. USING PRESELECTED CHARACTERISTICS, WE USED LOGISTIC REGRESSION TO IDENTIFY PREDICTORS OF "RESPONSE," DEFINED AS A >/=30% IMPROVEMENT IN THE ROLAND MORRIS DISABILITY QUESTIONNAIRE. THEN, USING "RESPONSE" AS OUR OUTCOME, WE IDENTIFIED BASELINE CHARACTERISTICS THAT WERE TREATMENT EFFECT MODIFIERS BY TESTING FOR STATISTICAL INTERACTION (P < 0.05) ACROSS TWO COMPARISONS: 1) YOGA-OR-PT VS SELF-CARE AND 2) YOGA VS PT. RESULTS: OVERALL, 39% (116/299) OF PARTICIPANTS WERE RESPONDERS, WITH MORE RESPONDERS IN THE YOGA-OR-PT GROUP (42%) THAN THE SELF-CARE (23%) GROUP. THERE WAS NO DIFFERENCE IN PROPORTION RESPONDING TO YOGA (48%) VS PT (37%, ODDS RATIO [OR] = 1.5, 95% CONFIDENCE INTERVAL = 0.88 - 2.6). PREDICTORS OF RESPONSE INCLUDED HAVING MORE THAN A HIGH SCHOOL EDUCATION, A HIGHER INCOME, EMPLOYMENT, FEW DEPRESSIVE SYMPTOMS, LOWER PERCEIVED STRESS, FEW WORK-RELATED FEAR AVOIDANCE BELIEFS, HIGH PAIN SELF-EFFICACY, AND BEING A NONSMOKER. EFFECT MODIFIERS INCLUDED USE OF PAIN MEDICATION AND FEAR AVOIDANCE BELIEFS RELATED TO PHYSICAL ACTIVITY (BOTH P = 0.02 FOR INTERACTION). WHEN COMPARING YOGA OR PT WITH SELF-CARE, A GREATER PROPORTION WERE RESPONDERS AMONG THOSE USING PAIN MEDS (OR = 5.3), WHICH DIFFERED FROM THOSE NOT TAKING PAIN MEDS (OR = 0.94) AT BASELINE. WE ALSO FOUND GREATER TREATMENT RESPONSE AMONG THOSE WITH LOWER (OR = 7.0), BUT NOT HIGH (OR = 1.3), FEAR AVOIDANCE BELIEFS AROUND PHYSICAL ACTIVITY. CONCLUSIONS: OUR FINDINGS REVEALED IMPORTANT SUBGROUPS FOR WHOM REFERRAL TO YOGA OR PT MAY IMPROVE CLBP OUTCOMES.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
19 2821  69 YOGA TREATMENT FOR CHRONIC NON-SPECIFIC LOW BACK PAIN. BACKGROUND: NON-SPECIFIC LOW BACK PAIN IS A COMMON, POTENTIALLY DISABLING CONDITION USUALLY TREATED WITH SELF-CARE AND NON-PRESCRIPTION MEDICATION. FOR CHRONIC LOW BACK PAIN, CURRENT GUIDELINES STATE THAT EXERCISE THERAPY MAY BE BENEFICIAL. YOGA IS A MIND-BODY EXERCISE SOMETIMES USED FOR NON-SPECIFIC LOW BACK PAIN. OBJECTIVES: TO ASSESS THE EFFECTS OF YOGA FOR TREATING CHRONIC NON-SPECIFIC LOW BACK PAIN, COMPARED TO NO SPECIFIC TREATMENT, A MINIMAL INTERVENTION (E.G. EDUCATION), OR ANOTHER ACTIVE TREATMENT, WITH A FOCUS ON PAIN, FUNCTION, AND ADVERSE EVENTS. SEARCH METHODS: WE SEARCHED CENTRAL, MEDLINE, EMBASE, FIVE OTHER DATABASES AND FOUR TRIALS REGISTERS TO 11 MARCH 2016 WITHOUT RESTRICTION OF LANGUAGE OR PUBLICATION STATUS. WE SCREENED REFERENCE LISTS AND CONTACTED EXPERTS IN THE FIELD TO IDENTIFY ADDITIONAL STUDIES. SELECTION CRITERIA: WE INCLUDED RANDOMIZED CONTROLLED TRIALS OF YOGA TREATMENT IN PEOPLE WITH CHRONIC NON-SPECIFIC LOW BACK PAIN. WE INCLUDED STUDIES COMPARING YOGA TO ANY OTHER INTERVENTION OR TO NO INTERVENTION. WE ALSO INCLUDED STUDIES COMPARING YOGA AS AN ADJUNCT TO OTHER THERAPIES, VERSUS THOSE OTHER THERAPIES ALONE. DATA COLLECTION AND ANALYSIS: TWO AUTHORS INDEPENDENTLY SCREENED AND SELECTED STUDIES, EXTRACTED OUTCOME DATA, AND ASSESSED RISK OF BIAS. WE CONTACTED STUDY AUTHORS TO OBTAIN MISSING OR UNCLEAR INFORMATION. WE EVALUATED THE OVERALL CERTAINTY OF EVIDENCE USING THE GRADE APPROACH. MAIN RESULTS: WE INCLUDED 12 TRIALS (1080 PARTICIPANTS) CARRIED OUT IN THE USA (SEVEN TRIALS), INDIA (THREE TRIALS), AND THE UK (TWO TRIALS). STUDIES WERE UNFUNDED (ONE TRIAL), FUNDED BY A YOGA INSTITUTION (ONE TRIAL), FUNDED BY NON-PROFIT OR GOVERNMENT SOURCES (SEVEN TRIALS), OR DID NOT REPORT ON FUNDING (THREE TRIALS). MOST TRIALS USED IYENGAR, HATHA, OR VINIYOGA FORMS OF YOGA. THE TRIALS COMPARED YOGA TO NO INTERVENTION OR A NON-EXERCISE INTERVENTION SUCH AS EDUCATION (SEVEN TRIALS), AN EXERCISE INTERVENTION (THREE TRIALS), OR BOTH EXERCISE AND NON-EXERCISE INTERVENTIONS (TWO TRIALS). ALL TRIALS WERE AT HIGH RISK OF PERFORMANCE AND DETECTION BIAS BECAUSE PARTICIPANTS AND PROVIDERS WERE NOT BLINDED TO TREATMENT ASSIGNMENT, AND OUTCOMES WERE SELF-ASSESSED. THEREFORE, WE DOWNGRADED ALL OUTCOMES TO 'MODERATE' CERTAINTY EVIDENCE BECAUSE OF RISK OF BIAS, AND WHEN THERE WAS ADDITIONAL SERIOUS RISK OF BIAS, UNEXPLAINED HETEROGENEITY BETWEEN STUDIES, OR THE ANALYSES WERE IMPRECISE, WE DOWNGRADED THE CERTAINTY OF THE EVIDENCE FURTHER.FOR YOGA COMPARED TO NON-EXERCISE CONTROLS (9 TRIALS; 810 PARTICIPANTS), THERE WAS LOW-CERTAINTY EVIDENCE THAT YOGA PRODUCED SMALL TO MODERATE IMPROVEMENTS IN BACK-RELATED FUNCTION AT THREE TO FOUR MONTHS (STANDARDIZED MEAN DIFFERENCE (SMD) -0.40, 95% CONFIDENCE INTERVAL (CI) -0.66 TO -0.14; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MEAN DIFFERENCE (MD) -2.18, 95% -3.60 TO -0.76), MODERATE-CERTAINTY EVIDENCE FOR SMALL TO MODERATE IMPROVEMENTS AT SIX MONTHS (SMD -0.44, 95% CI -0.66 TO -0.22; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD -2.15, 95% -3.23 TO -1.08), AND LOW-CERTAINTY EVIDENCE FOR SMALL IMPROVEMENTS AT 12 MONTHS (SMD -0.26, 95% CI -0.46 TO -0.05; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD -1.36, 95% -2.41 TO -0.26). ON A 0-100 SCALE THERE WAS VERY LOW- TO MODERATE-CERTAINTY EVIDENCE THAT YOGA WAS SLIGHTLY BETTER FOR PAIN AT THREE TO FOUR MONTHS (MD -4.55, 95% CI -7.04 TO -2.06), SIX MONTHS (MD -7.81, 95% CI -13.37 TO -2.25), AND 12 MONTHS (MD -5.40, 95% CI -14.50 TO -3.70), HOWEVER WE PRE-DEFINED CLINICALLY SIGNIFICANT CHANGES IN PAIN AS 15 POINTS OR GREATER AND THIS THRESHOLD WAS NOT MET. BASED ON INFORMATION FROM SIX TRIALS, THERE WAS MODERATE-CERTAINTY EVIDENCE THAT THE RISK OF ADVERSE EVENTS, PRIMARILY INCREASED BACK PAIN, WAS HIGHER IN YOGA THAN IN NON-EXERCISE CONTROLS (RISK DIFFERENCE (RD) 5%, 95% CI 2% TO 8%).FOR YOGA COMPARED TO NON-YOGA EXERCISE CONTROLS (4 TRIALS; 394 PARTICIPANTS), THERE WAS VERY-LOW-CERTAINTY EVIDENCE FOR LITTLE OR NO DIFFERENCE IN BACK-RELATED FUNCTION AT THREE MONTHS (SMD -0.22, 95% CI -0.65 TO 0.20; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD -0.99, 95% -2.87 TO 0.90) AND SIX MONTHS (SMD -0.20, 95% CI -0.59 TO 0.19; CORRESPONDING TO A CHANGE IN THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE OF MD -0.90, 95% -2.61 TO 0.81), AND NO INFORMATION ON BACK-RELATED FUNCTION AFTER SIX MONTHS. THERE WAS VERY LOW-CERTAINTY EVIDENCE FOR LOWER PAIN ON A 0-100 SCALE AT SEVEN MONTHS (MD -20.40, 95% CI -25.48 TO -15.32), AND NO INFORMATION ON PAIN AT THREE MONTHS OR AFTER SEVEN MONTHS. BASED ON INFORMATION FROM THREE TRIALS, THERE WAS LOW-CERTAINTY EVIDENCE FOR NO DIFFERENCE IN THE RISK OF ADVERSE EVENTS BETWEEN YOGA AND NON-YOGA EXERCISE CONTROLS (RD 1%, 95% CI -4% TO 6%).FOR YOGA ADDED TO EXERCISE COMPARED TO EXERCISE ALONE (1 TRIAL; 24 PARTICIPANTS), THERE WAS VERY-LOW-CERTAINTY EVIDENCE FOR LITTLE OR NO DIFFERENCE AT 10 WEEKS IN BACK-RELATED FUNCTION (SMD -0.60, 95% CI -1.42 TO 0.22; CORRESPONDING TO A CHANGE IN THE OSWESTRY DISABILITY INDEX OF MD -17.05, 95% -22.96 TO 11.14) OR PAIN ON A 0-100 SCALE (MD -3.20, 95% CI -13.76 TO 7.36). THERE WAS NO INFORMATION ON OUTCOMES AT OTHER TIME POINTS. THERE WAS NO INFORMATION ON ADVERSE EVENTS.STUDIES PROVIDED LIMITED EVIDENCE ON RISK OF CLINICAL IMPROVEMENT, MEASURES OF QUALITY OF LIFE, AND DEPRESSION. THERE WAS NO EVIDENCE ON WORK-RELATED DISABILITY. AUTHORS' CONCLUSIONS: THERE IS LOW- TO MODERATE-CERTAINTY EVIDENCE THAT YOGA COMPARED TO NON-EXERCISE CONTROLS RESULTS IN SMALL TO MODERATE IMPROVEMENTS IN BACK-RELATED FUNCTION AT THREE AND SIX MONTHS. YOGA MAY ALSO BE SLIGHTLY MORE EFFECTIVE FOR PAIN AT THREE AND SIX MONTHS, HOWEVER THE EFFECT SIZE DID NOT MEET PREDEFINED LEVELS OF MINIMUM CLINICAL IMPORTANCE. IT IS UNCERTAIN WHETHER THERE IS ANY DIFFERENCE BETWEEN YOGA AND OTHER EXERCISE FOR BACK-RELATED FUNCTION OR PAIN, OR WHETHER YOGA ADDED TO EXERCISE IS MORE EFFECTIVE THAN EXERCISE ALONE. YOGA IS ASSOCIATED WITH MORE ADVERSE EVENTS THAN NON-EXERCISE CONTROLS, BUT MAY HAVE THE SAME RISK OF ADVERSE EVENTS AS OTHER BACK-FOCUSED EXERCISE. YOGA IS NOT ASSOCIATED WITH SERIOUS ADVERSE EVENTS. THERE IS A NEED FOR ADDITIONAL HIGH-QUALITY RESEARCH TO IMPROVE CONFIDENCE IN ESTIMATES OF EFFECT, TO EVALUATE LONG-TERM OUTCOMES, AND TO PROVIDE ADDITIONAL INFORMATION ON COMPARISONS BETWEEN YOGA AND OTHER EXERCISE FOR CHRONIC NON-SPECIFIC LOW BACK PAIN.	2017	

20 2518  59 YOGA COMPARED TO NON-EXERCISE OR PHYSICAL THERAPY EXERCISE ON PAIN, DISABILITY, AND QUALITY OF LIFE FOR PATIENTS WITH CHRONIC LOW BACK PAIN: A SYSTEMATIC REVIEW AND META-ANALYSIS OF RANDOMIZED CONTROLLED TRIALS. BACKGROUND: CHRONIC LOW BACK PAIN (CLBP) IS A COMMON AND OFTEN DISABLING MUSCULOSKELETAL CONDITION. YOGA HAS BEEN PROVEN TO BE AN EFFECTIVE THERAPY FOR CHRONIC LOW BACK PAIN. HOWEVER, THERE ARE STILL CONTROVERSIES ABOUT THE EFFECTS OF YOGA AT DIFFERENT FOLLOW-UP PERIODS AND COMPARED WITH OTHER PHYSICAL THERAPY EXERCISES. OBJECTIVE: TO CRITICALLY COMPARE THE EFFECTS OF YOGA FOR PATIENTS WITH CHRONIC LOW BACK PAIN ON PAIN, DISABILITY, QUALITY OF LIFE WITH NON-EXERCISE (E.G. USUAL CARE, EDUCATION), PHYSICAL THERAPY EXERCISE. METHODS: THIS STUDY WAS REGISTERED IN PROSPERO, AND THE REGISTRATION NUMBER WAS CRD42020159865. RANDOMIZED CONTROLLED TRIALS (RCTS) OF ONLINE DATABASES INCLUDED PUBMED, WEB OF SCIENCE, COCHRANE CENTRAL REGISTER OF CONTROLLED TRIALS, EMBASE WHICH EVALUATED EFFECTS OF YOGA FOR PATIENTS WITH CHRONIC LOW BACK PAIN ON PAIN, DISABILITY, AND QUALITY OF LIFE WERE SEARCHED FROM INCEPTION TIME TO NOVEMBER 1, 2019. STUDIES WERE ELIGIBLE IF THEY ASSESSED AT LEAST ONE IMPORTANT OUTCOME, NAMELY PAIN, BACK-SPECIFIC DISABILITY, QUALITY OF LIFE. THE COCHRANE RISK OF BIAS TOOL WAS USED TO ASSESS THE METHODOLOGICAL QUALITY OF INCLUDED RANDOMIZED CONTROLLED TRIALS. THE CONTINUOUS OUTCOMES WERE ANALYZED BY CALCULATING THE MEAN DIFFERENCE (MD) OR STANDARDIZED MEAN DIFFERENCE (SMD) WITH 95% CONFIDENCE INTERVALS (CI) ACCORDING TO WHETHER COMBINING OUTCOMES MEASURED ON DIFFERENT SCALES OR NOT. RESULTS: A TOTAL OF 18 RANDOMIZED CONTROLLED TRIALS WERE INCLUDED IN THIS META-ANALYSIS. YOGA COULD SIGNIFICANTLY REDUCE PAIN AT 4 TO 8 WEEKS (MD = -0.83, 95% CI = -1.19 TO -0.48, P<0.00001, I2 = 0%), 3 MONTHS (MD = -0.43, 95% CI = -0.64 TO -0.23, P<0.0001, I2 = 0%), 6 TO 7 MONTHS (MD = -0.56, 95% CI = -1.02 TO -0.11, P = 0.02, I2 = 50%), AND WAS NOT SIGNIFICANT IN 12 MONTHS (MD = -0.52, 95% CI = -1.64 TO 0.59, P = 0.36, I2 = 87%) COMPARED WITH NON-EXERCISE. YOGA WAS BETTER THAN NON-EXERCISE ON DISABILITY AT 4 TO 8 WEEKS (SMD = -0.30, 95% CI = -0.51 TO -0.10, P = 0.003, I2 = 0%), 3 MONTHS (SMD = -0.31, 95% CI = -0.45 TO -0.18, P<0.00001, I2 = 30%), 6 MONTHS (SMD = -0.38, 95% CI = -0.53 TO -0.23, P<0.00001, I2 = 0%), 12 MONTHS (SMD = -0.33, 95% CI = -0.54 TO -0.12, P = 0.002, I2 = 9%). THERE WAS NO SIGNIFICANT DIFFERENCE ON PAIN, DISABILITY COMPARED WITH PHYSICAL THERAPY EXERCISE GROUP. FURTHERMORE, IT SUGGESTED THAT THERE WAS A NON-SIGNIFICANT DIFFERENCE ON PHYSICAL AND MENTAL QUALITY OF LIFE BETWEEN YOGA AND ANY OTHER INTERVENTIONS. CONCLUSION: THIS META-ANALYSIS PROVIDED EVIDENCE FROM VERY LOW TO MODERATE INVESTIGATING THE EFFECTIVENESS OF YOGA FOR CHRONIC LOW BACK PAIN PATIENTS AT DIFFERENT TIME POINTS. YOGA MIGHT DECREASE PAIN FROM SHORT TERM TO INTERMEDIATE TERM AND IMPROVE FUNCTIONAL DISABILITY STATUS FROM SHORT TERM TO LONG TERM COMPARED WITH NON-EXERCISE (E.G. USUAL CARE, EDUCATION). YOGA HAD THE SAME EFFECT ON PAIN AND DISABILITY AS ANY OTHER EXERCISE OR PHYSICAL THERAPY. YOGA MIGHT NOT IMPROVE THE PHYSICAL AND MENTAL QUALITY OF LIFE BASED ON THE RESULT OF A MERGING.	2020
