1 2852 177 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.

2  518  65 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.

3 1699  79 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
4 2330  26 TWELVE WEEKS OF YOGA FOR CHRONIC NONSPECIFIC LOWER BACK PAIN: A META-ANALYSIS. OBJECTIVES: TO INVESTIGATE THE OVERALL EFFECTS OF 12 WEEKS OF YOGA PRACTICE ON CHRONIC NONSPECIFIC LOWER BACK PAIN. METHODS: PUBMED, EMBASE, PSYCINFO, WEB OF SCIENCE, AND THE COCHRANE LIBRARY DATABASES WERE SEARCHED FROM INCEPTION TO FEBRUARY 9, 2019, AND SIX RANDOMIZED CONTROLLED TRIALS WERE SELECTED FOR THIS META-ANALYSIS. RESULTS: THE POOLED FIXED-EFFECT SIZE OF SIX TRIALS SHOWED THAT 12 WEEKS OF YOGA PROGRAMS COULD SIGNIFICANTLY REDUCE CHRONIC NONSPECIFIC LOWER BACK PAIN BY 0.41 WITHIN THE TRIALS (STANDARDIZED MEAN DIFFERENCE; 95% CONFIDENCE INTERVAL: -0.58 TO -0.23; P < .0001). SUBGROUP ANALYSES ALSO SHOWED THAT SIGNIFICANT PAIN REDUCTION WAS RELATED TO TYPE OF YOGA, LENGTH OF SESSION, STUDY QUALITY, AND TIMING OF PAIN ASSESSMENT. CONCLUSIONS: THESE FINDINGS REVEAL THAT 12 WEEKS OF YOGA CAN HELP ALLEVIATE PAIN, AND YOGA PROGRAMS SHOULD TAKE INTO ACCOUNT THE SUBGROUP FACTORS TO INCREASE INDIVIDUALS' RELIEF FROM CHRONIC NONSPECIFIC LOWER BACK PAIN.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
5 2831  71 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.

6 1074  49 EFFECTS OF YOGA ON PATIENTS WITH CHRONIC NONSPECIFIC NECK PAIN: A PRISMA SYSTEMATIC REVIEW AND META-ANALYSIS. BACKGROUND: CHRONIC NONSPECIFIC NECK PAIN (CNNP) HAS A HIGH PREVALENCE AND IS MORE COMMON AMONG YOUNGER PEOPLE. CLINICAL PRACTICE SUGGESTS THAT YOGA IS EFFECTIVE IN RELIEVING CHRONIC PAIN. OBJECTIVES: THIS META-ANALYSIS AIMED TO QUANTITATIVELY SUMMARIZE THE EFFICACY OF YOGA FOR TREATING CNNP. DATA SOURCES: WE SEARCHED FOR TRIALS IN THE ELECTRONIC DATABASES FROM THEIR INCEPTION TO JANUARY 2019. ENGLISH DATABASES INCLUDING PUBMED, MEDLINE, COCHRANE LIBRARY, EMBASE, SCOPUS, THE COCHRANE CENTRAL REGISTER OF CONTROLLED TRIALS, AND IND MED; CHINESE DATABASES INCLUDING CHINA NATIONAL KNOWLEDGE INFRASTRUCTURE (CNKI), WANFANG DATABASE, AND VIP INFORMATION. WE ALSO CONDUCTED A MANUAL SEARCH OF KEY JOURNALS AND THE REFERENCE LISTS OF ELIGIBLE PAPERS TO IDENTIFY ANY POTENTIALLY RELEVANT STUDIES WE MAY HAVE MISSED. WE PLACED NO LIMITATIONS ON LANGUAGE OR DATE OF PUBLICATION. STUDY ELIGIBILITY CRITERIA: WE INCLUDED ONLY RANDOMIZED CONTROLLED TRIALS (RCTS) AND Q-RCTS EVALUATING THE EFFECTS OF YOGA ON PATIENTS WITH CNNP. THE PRIMARY OUTCOMES FOR THIS REVIEW WERE PAIN AND DISABILITY, AND THE SECONDARY OUTCOMES WERE CERVICAL RANGE OF MOTION (CROM), QUALITY OF LIFE (QOL), AND MOOD. PARTICIPANTS AND INTERVENTIONS: TRAILS THAT EXAMINED THE CLINICAL OUTCOMES OF YOGA INTERVENTION IN ADULTS WITH CNNP COMPARED WITH THOSE OF OTHER THERAPIES EXCEPT YOGA (E.G., EXERCISE, PILATES, USUAL CARE, ET AL) WERE INCLUDED. STUDY APPRAISAL AND SYNTHESIS METHODS: COCHRANE RISK-OF-BIAS CRITERIA WERE USED TO ASSESS THE METHODOLOGICAL QUALITY, AND REVMAN 5.3 SOFTWARE WAS USED TO CONDUCT THE META-ANALYSIS. RESULTS: A TOTAL OF 10 TRIALS (N = 686) COMPARING YOGA AND INTERVENTIONS OTHER THAN YOGA WERE INCLUDED IN THE META-ANALYSIS. THE RESULTS SHOW THAT YOGA HAD A POSITIVE EFFECTS ON NECK PAIN INTENSITY (TOTAL EFFECT: SMD = -1.13, 95% CI [-1.60, -0.66], Z = 4.75, P < .00001), NECK PAIN-RELATED FUNCTIONAL DISABILITY (TOTAL EFFECT: SMD = -0.92, 95% CI [-1.38, -0.47], Z = 3.95, P < .0001), CROM (TOTAL EFFECT: SMD = 1.22, 95% CI [0.87, 1.57], Z = 6.83, P < .00001), QOL (TOTAL EFFECT: MD = 3.46, 95% CI [0.75, 6.16], Z = 2.51, P = .01), AND MOOD (TOTAL EFFECT: SMD = -0.61, 95% CI [-0.95, -0.27], Z = 3.53, P = .0004). CONCLUSIONS AND IMPLICATIONS OF KEY FINDINGS: IT WAS DIFFICULT TO MAKE A COMPREHENSIVE SUMMARY OF ALL THE EVIDENCE DUE TO THE DIFFERENT SESSION AND DURATION OF THE YOGA INTERVENTIONS, AND THE DIFFERENT OUTCOME MEASUREMENT TOOLS IN THE STUDY, WE DRAW A VERY CAUTIOUS CONCLUSION THAT YOGA CAN RELIEVE NECK PAIN INTENSITY, IMPROVE PAIN-RELATED FUNCTION DISABILITY, INCREASE CROM, IMPROVE QOL, AND BOOST MOOD. THIS SUGGESTS THAT YOGA MIGHT BE AN IMPORTANT ALTERNATIVE IN THE TREATMENT OF CNNP.

7  521  69 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
8 1870  50 RANDOMIZED-CONTROLLED TRIAL COMPARING YOGA AND HOME-BASED EXERCISE FOR CHRONIC NECK PAIN. OBJECTIVES: CHRONIC NECK PAIN IS A SIGNIFICANT PUBLIC HEALTH PROBLEM WITH ONLY VERY FEW EVIDENCE-BASED TREATMENT OPTIONS. THERE IS GROWING EVIDENCE FOR THE EFFECTIVENESS OF YOGA FOR RELIEVING MUSCULOSKELETAL DISORDERS. THE AIM OF THIS STUDY WAS TO EVALUATE THE EFFECT OF IYENGAR YOGA COMPARED WITH EXERCISE ON CHRONIC NONSPECIFIC NECK PAIN. METHODS: PATIENTS WERE RANDOMLY ASSIGNED TO EITHER YOGA OR EXERCISE. THE YOGA GROUP ATTENDED A 9-WEEK YOGA COURSE AND THE EXERCISE GROUP RECEIVED A SELF-CARE MANUAL ON HOME-BASED EXERCISES FOR NECK PAIN RELIEF. THE MAIN OUTCOME MEASURE WAS THE PRESENT NECK PAIN INTENSITY (100 MM VISUAL ANALOG SCALE). SECONDARY OUTCOME MEASURES INCLUDED FUNCTIONAL DISABILITY (NECK DISABILITY INDEX), PAIN AT MOTION (VISUAL ANALOG SCALE), HEALTH-RELATED QUALITY OF LIFE (SHORT FORM-36 QUESTIONNAIRE), CERVICAL RANGE OF MOTION, PROPRIOCEPTIVE ACUITY, AND PRESSURE PAIN THRESHOLD. RESULTS: FIFTY-ONE PATIENTS (MEAN AGE 47.8 Y ; 82.4% FEMALE) WERE RANDOMIZED TO YOGA (N=25) AND EXERCISE (N=26) INTERVENTION. AFTER THE STUDY PERIOD, PATIENTS IN THE YOGA GROUP REPORTED SIGNIFICANTLY LESS NECK PAIN INTENSITY COMPARED WITH THE EXERCISE GROUP [MEAN DIFFERENCE: -13.9 MM (95% CI, -26.4 TO -1.4), P=0.03]. THE YOGA GROUP REPORTED LESS DISABILITY AND BETTER MENTAL QUALITY OF LIFE. RANGE OF MOTION AND PROPRIOCEPTIVE ACUITY WERE IMPROVED AND THE PRESSURE PAIN THRESHOLD WAS ELEVATED IN THE YOGA GROUP. DISCUSSION: YOGA WAS MORE EFFECTIVE IN RELIEVING CHRONIC NONSPECIFIC NECK PAIN THAN A HOME-BASED EXERCISE PROGRAM. YOGA REDUCED NECK PAIN INTENSITY AND DISABILITY AND IMPROVED HEALTH-RELATED QUALITY OF LIFE. MOREOVER, YOGA SEEMS TO INFLUENCE THE FUNCTIONAL STATUS OF NECK MUSCLES, AS INDICATED BY IMPROVEMENT OF PHYSIOLOGICAL MEASURES OF NECK PAIN.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
9  193  56 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.

10  465  55 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
11  461  54 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
12 1054  43 EFFECTS OF YOGA ON CHRONIC NECK PAIN: A SYSTEMATIC REVIEW AND META-ANALYSIS. OBJECTIVE: THE AIM OF THIS REVIEW WAS TO SYSTEMATICALLY ASSESS AND META-ANALYZE THE EFFECTIVENESS OF YOGA IN RELIEVING CHRONIC NECK PAIN. METHODS: PUBMED/MEDLINE, THE COCHRANE LIBRARY, SCOPUS, AND INDMED WERE SCREENED THROUGH JANUARY 2017 FOR RANDOMIZED CONTROLLED TRIALS ASSESSING NECK PAIN INTENSITY AND/OR NECK PAIN-RELATED DISABILITY IN CHRONIC NECK PAIN PATIENTS. SECONDARY OUTCOME MEASURES INCLUDED QUALITY OF LIFE, MOOD, AND SAFETY. RISK OF BIAS WAS ASSESSED USING THE COCHRANE TOOL. RESULTS: THREE STUDIES ON 188 PATIENTS WITH CHRONIC NON-SPECIFIC NECK PAIN COMPARING YOGA TO USUAL CARE WERE INCLUDED. TWO STUDIES HAD OVERALL LOW RISK OF BIAS; AND ONE HAD HIGH OR UNCLEAR RISK OF BIAS FOR SEVERAL DOMAINS. EVIDENCE FOR SHORT-TERM EFFECTS WAS FOUND FOR NECK PAIN INTENSITY (STANDARDIZED MEAN DIFFERENCE (SMD) = -1.28; 95% CONFIDENCE INTERVAL (CI) = -1.18, -0.75; P < 0.001), NECK PAIN-RELATED DISABILITY (SMD = -0.97; 95% CI = -1.44, -0.50; P < 0.001), QUALITY OF LIFE (SMD = 0.57; 95% CI = 0.17, 0.197; P = 0.005), AND MOOD (SMD = -1.02; 95% CI = -1.38, -0.65; P < 0.001). EFFECTS WERE ROBUST AGAINST POTENTIAL METHODOLOGICAL BIAS AND DID NOT DIFFER BETWEEN DIFFERENT INTERVENTION SUBGROUPS. IN THE TWO STUDIES THAT INCLUDED SAFETY DATA, NO SERIOUS ADVERSE EVENTS OCCURRED. CONCLUSION: YOGA HAS SHORT-TERM EFFECTS ON CHRONIC NECK PAIN, ITS RELATED DISABILITY, QUALITY OF LIFE, AND MOOD SUGGESTING THAT YOGA MIGHT BE A GOOD TREATMENT OPTION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
13 2560  70 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.

14 2851  74 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.

15 2558  68 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
16 2518  61 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	

17  638  52 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.

18 2813  27 YOGA TO TREAT NONSPECIFIC LOW BACK PAIN. LOW BACK PAIN IS COMMON AND POSES A CHALLENGE FOR CLINICIANS TO FIND EFFECTIVE TREATMENT TO PREVENT IT FROM BECOMING CHRONIC. CHRONIC LOW BACK PAIN CAN HAVE A SIGNIFICANT IMPACT ON AN EMPLOYEE'S ABILITY TO REMAIN AN ACTIVE AND PRODUCTIVE MEMBER OF THE WORK FORCE DUE TO INCREASED ABSENTEEISM, DUTY RESTRICTIONS, OR PHYSICAL LIMITATIONS FROM PAIN. LOW BACK PAIN IS THE MOST COMMON CAUSE OF WORK-RELATED DISABILITY AMONG EMPLOYEES YOUNGER THAN 46 YEARS. ADVANCING TECHNOLOGY AND LESS INVASIVE SURGICAL PROCEDURES HAVE NOT IMPROVED OUTCOMES FOR EMPLOYEES WHO SUFFER FROM LOW BACK PAIN. MOST CONTINUE TO EXPERIENCE SOME PAIN AND DYSFUNCTION AFTER CONVENTIONAL TREATMENTS SUCH AS INJECTIONS AND SURGERY. AN ALTERNATIVE TREATMENT THAT COULD REDUCE NONSPECIFIC CHRONIC LOW BACK PAIN WOULD BENEFIT BOTH EMPLOYEES AND EMPLOYERS. EXERCISING AND REMAINING ACTIVE ARE PART OF MOST GUIDELINES' ROUTINE CARE RECOMMENDATIONS BUT ARE NOT WELL DEFINED.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
19 2596  66 YOGA FOR MILITARY VETERANS WITH CHRONIC LOW BACK PAIN: A RANDOMIZED CLINICAL TRIAL. INTRODUCTION: CHRONIC LOW BACK PAIN (CLBP) IS PREVALENT, ESPECIALLY AMONG MILITARY VETERANS. MANY CLBP TREATMENT OPTIONS HAVE LIMITED BENEFITS AND ARE ACCOMPANIED BY SIDE EFFECTS. MAJOR EFFORTS TO REDUCE OPIOID USE AND EMBRACE NONPHARMACOLOGICAL PAIN TREATMENTS HAVE RESULTED. RESEARCH WITH COMMUNITY CLBP PATIENTS INDICATES THAT YOGA CAN IMPROVE HEALTH OUTCOMES AND HAS FEW SIDE EFFECTS. THE BENEFITS OF YOGA AMONG MILITARY VETERANS WERE EXAMINED. DESIGN: PARTICIPANTS WERE RANDOMIZED TO EITHER YOGA OR DELAYED YOGA TREATMENT IN 2013-2015. OUTCOMES WERE ASSESSED AT BASELINE, 6 WEEKS, 12 WEEKS, AND 6 MONTHS. INTENTION-TO-TREAT ANALYSES OCCURRED IN 2016. SETTING/PARTICIPANTS: ONE HUNDRED AND FIFTY MILITARY VETERANS WITH CLBP WERE RECRUITED FROM A MAJOR VETERANS AFFAIRS MEDICAL CENTER IN CALIFORNIA. INTERVENTION: YOGA CLASSES (WITH HOME PRACTICE) WERE LED BY A CERTIFIED INSTRUCTOR TWICE WEEKLY FOR 12 WEEKS, AND CONSISTED PRIMARILY OF PHYSICAL POSTURES, MOVEMENT, AND BREATHING TECHNIQUES. MAIN OUTCOME MEASURES: THE PRIMARY OUTCOME WAS ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES AFTER 12 WEEKS. PAIN INTENSITY WAS IDENTIFIED AS AN IMPORTANT SECONDARY OUTCOME. RESULTS: PARTICIPANT CHARACTERISTICS WERE MEAN AGE 53 YEARS, 26% WERE FEMALE, 35% WERE UNEMPLOYED OR DISABLED, AND MEAN BACK PAIN DURATION WAS 15 YEARS. IMPROVEMENTS IN ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES DID NOT DIFFER BETWEEN THE TWO GROUPS AT 12 WEEKS, BUT YOGA PARTICIPANTS HAD GREATER REDUCTIONS IN ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES THAN DELAYED TREATMENT PARTICIPANTS AT 6 MONTHS -2.48 (95% CI= -4.08, -0.87). YOGA PARTICIPANTS IMPROVED MORE ON PAIN INTENSITY AT 12 WEEKS AND AT 6 MONTHS. OPIOID MEDICATION USE DECLINED AMONG ALL PARTICIPANTS, BUT GROUP DIFFERENCES WERE NOT FOUND. CONCLUSIONS: YOGA IMPROVED HEALTH OUTCOMES AMONG VETERANS DESPITE EVIDENCE THEY HAD FEWER RESOURCES, WORSE HEALTH, AND MORE CHALLENGES ATTENDING YOGA SESSIONS THAN COMMUNITY SAMPLES STUDIED PREVIOUSLY. THE MAGNITUDE OF PAIN INTENSITY DECLINE WAS SMALL, BUT OCCURRED IN THE CONTEXT OF REDUCED OPIOID USE. THE FINDINGS SUPPORT WIDER IMPLEMENTATION OF YOGA PROGRAMS FOR VETERANS.

20 1787  52 PREFERENCE AND EXPECTATION FOR TREATMENT ASSIGNMENT IN A RANDOMIZED CONTROLLED TRIAL OF ONCE- VS TWICE-WEEKLY YOGA FOR CHRONIC LOW BACK PAIN. BACKGROUND: IN STUDIES INVOLVING NONPHARMACOLOGICAL COMPLEMENTARY AND ALTERNATIVE MEDICINE INTERVENTIONS, PARTICIPANT BLINDING IS VERY DIFFICULT. PARTICIPANT EXPECTATIONS MAY AFFECT PERCEIVED BENEFIT OF THERAPY. IN STUDIES OF YOGA AS TREATMENT FOR CHRONIC LOW BACK PAIN, LITTLE IS KNOWN ABOUT THE RELATIONSHIP BETWEEN PATIENT EXPECTATIONS AND PREFERENCES ON OUTCOMES. THIS STUDY WAS DESIGNED TO IDENTIFY BASELINE PREDICTORS OF PREFERENCE AND TO DETERMINE IF EXPECTATIONS AND PREFERENCES FOR DIFFERENT DOSES OF YOGA AFFECT BACK-RELATED FUNCTION AND LOW BACK PAIN INTENSITY. METHODS: THIS WAS A SECONDARY DATA ANALYSIS OF A 12-WEEK RANDOMIZED CONTROLLED TRIAL COMPARING ONCE-WEEKLY VS TWICE-WEEKLY YOGA FOR TREATMENT OF CHRONIC LOW BACK PAIN IN 93 ADULTS FROM A PREDOMINANTLY LOW-INCOME MINORITY POPULATION. AT BASELINE, PARTICIPANTS WERE ASKED ABOUT BACK FUNCTION, BACK PAIN, TREATMENT EXPECTATIONS, AND TREATMENT PREFERENCES. WE CREATED A VARIABLE "CONCORDANCE" TO DESCRIBE THE MATCHING OF PARTICIPANT PREFERENCE TO RANDOMIZED TREATMENT. OUR OUTCOME VARIABLES WERE CHANGE IN BACK FUNCTION AND PAIN INTENSITY AFTER 12 WEEKS OF YOGA INSTRUCTION. WE PERFORMED LOGISTIC REGRESSION TO IDENTIFY PREDICTORS OF PREFERENCE FOR ONCE- OR TWICE-WEEKLY YOGA INSTRUCTION. WE CREATED LINEAR REGRESSION MODELS TO IDENTIFY INDEPENDENT ASSOCIATIONS BETWEEN EXPECTATIONS, PREFERENCE, CONCORDANCE, AND OUTCOMES. RESULTS: WORSE BACK FUNCTION AT BASELINE WAS ASSOCIATED WITH 20% HIGHER ODDS OF PREFERRING TWICE-WEEKLY YOGA (OR 1.2, CI 1.1, 1.3). INDIVIDUALS WITH HIGHER EXPECTATION SCORES FOR TWICE-WEEKLY YOGA HAD 90% HIGHER ODDS OF PREFERRING TWICE-WEEKLY VS ONCE-WEEKLY YOGA (OR 1.9, CI 1.3, 2.7). INDIVIDUALS WITH HIGHER EXPECTATION SCORES FOR ONCE-WEEKLY YOGA HAD 40% LESS ODDS OF PREFERRING TWICE-WEEKLY YOGA (OR 0.6, CI 0.5, 0.9). AFTER CONTROLLING FOR BASELINE CHARACTERISTICS, WE FOUND NO STATISTICALLY SIGNIFICANT RELATIONSHIP BETWEEN TREATMENT OUTCOMES, PREFERENCE, EXPECTATION SCORES, OR CONCORDANCE. CONCLUSION: IN A POPULATION OF PREDOMINANTLY LOW-INCOME MINORITY PARTICIPANTS WITH CHRONIC LOW BACK PAIN, WORSE BACK FUNCTION WAS ASSOCIATED WITH PREFERENCE FOR MORE FREQUENT YOGA CLASSES. THOSE WHO PREFERRED MORE YOGA CLASSES HAD HIGHER EXPECTATIONS FOR THOSE CLASSES. TWELVE-WEEK CHANGE IN BACK PAIN INTENSITY AND BACK FUNCTION WERE NOT AFFECTED BY DOSING PREFERENCE, EXPECTATION SCORE, OR CONCORDANCE. MORE RESEARCH IS NEEDED TO BETTER MEASURE AND QUANTIFY PREFERENCE, EXPECTATIONS, AND THEIR RELATIONSHIP TO OUTCOMES IN YOGA RESEARCH.	2015
