1 2558 177 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                       
2  518  60 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. THIS TRIAL IS REGISTERED WITH CLINICALTRIALS.GOV NCT01761617.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
3 2641  45 YOGA FOR WARRIORS: AN INTERVENTION FOR VETERANS WITH COMORBID CHRONIC PAIN AND PTSD. OBJECTIVE: COMORBID CHRONIC PAIN AND POSTTRAUMATIC STRESS DISORDER (PTSD) IS COMMON IN VETERANS; THIS COMORBIDITY IS ASSOCIATED WITH INCREASED SEVERITY AND POORER PROGNOSIS WHEN COMPARED TO EACH OUTCOME ALONE. YOGA HAS BEEN SHOWN TO BE EFFECTIVE FOR CHRONIC PAIN AND PROMISING FOR PTSD, BUT YOGA FOR COMORBID PAIN AND PTSD HAS NOT BEEN EXAMINED. THIS ARTICLE OFFERS EMPIRICAL SUPPORT FOR A YOGA INTERVENTION FOR COMORBID CHRONIC PAIN AND PTSD IN A VETERAN POPULATION. METHOD: RESULTS ARE PRESENTED FROM A 4-YEAR PILOT YOGA INTERVENTION FOR COMORBID CHRONIC PAIN AND PTSD AT A LARGE, URBAN VETERANS AFFAIRS MEDICAL CENTER. BASED ON THE FEAR AVOIDANCE MODEL OF PAIN, THE INTERVENTION USED A CROSS-SECTIONAL, OPEN-TRIAL DESIGN WITH PRE- AND POSTMEASURES. T TEST ANALYSES WERE CONDUCTED ON PROGRAM COMPLETERS (N = 49; OUT OF 87 INITIALLY ENROLLED, 44% ATTRITION RATE), WHO WERE PRIMARILY AFRICAN AMERICAN (69%) AND MALE (61%) AND HAD A MEAN AGE OF 51.41 YEARS (SD = 11.32). RESULTS: RESULTS INDICATED TREND-LEVEL REDUCTIONS IN OVERALL PTSD SYMPTOMS, AS MEASURED BY THE PTSD CHECKLIST FOR DSM-5 (P = .02, D = 0.38) AND IN SYMPTOM CLUSTER SCORES OF NEGATIVE ALTERATIONS OF COGNITIONS AND MOOD (P = .03, D = 0.36) AND AROUSAL AND REACTIVITY (P = .03, D = 0.35). VETERANS REPORTED SIGNIFICANT IMPROVEMENT IN ABILITY TO PARTICIPATE IN SOCIAL ACTIVITIES (P < .001, D = 0.44) AND SIGNIFICANT REDUCTIONS IN KINESIOPHOBIA (FEAR OF MOVEMENT OR PHYSICAL ACTIVITY; P < .001, D = 0.85). ON A SATISFACTION MEASURE WITH A RANGE OF 1 (QUITE DISSATISFIED) TO 4 (EXTREMELY SATISFIED), THE MEAN RATING WAS 3.74 (SD = 0.33). CONCLUSION: YOGA IS A FEASIBLE AND EFFECTIVE INTERVENTION FOR VETERANS WITH COMORBID CHRONIC PAIN AND PTSD.

4 1699  76 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	
                                                                                                                                                                                                                                                                                                                                                                                           
5 2852  68 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.

6 1215  41 EXPLORING THE EFFECTS OF YOGA THERAPY ON HEART RATE VARIABILITY AND PATIENT-REPORTED OUTCOMES AFTER CANCER TREATMENT: A STUDY PROTOCOL. BACKGROUND: FOLLOWING CANCER TREATMENT, ADULTS COMMONLY REPORT WORSENED PATIENT-REPORTED OUTCOMES (PROS) SUCH AS ANXIETY, STRESS, DEPRESSION, PERSISTENT AND UPSETTING COGNITIVE COMPLAINTS, UNRELENTING FATIGUE, AND REDUCED QUALITY OF LIFE. POORER PROS ARE ASSOCIATED WITH DISRUPTED AUTONOMIC NERVOUS SYSTEM FUNCTIONING AS MEASURED BY HEART RATE VARIABILITY (HRV), BOTH OF WHICH HAVE BEEN ASSOCIATED WITH GREATER MORBIDITY AND MORTALITY. INTERVENTIONS TO IMPROVE HRV AND PROS AMONG ADULTS FOLLOWING CANCER TREATMENT ARE NEEDED. YOGA THERAPY HOLDS PROMISE AS AN INTERVENTION TO IMPROVE HRV AND PROS. THEREFORE, WE CONDUCTED A SINGLE-SUBJECT EXPLORATORY EXPERIMENTAL STUDY TO INVESTIGATE THE EFFECTS OF YOGA THERAPY ON HRV AND SPECIFIC PROS (IE, CANCER-RELATED FATIGUE, ANXIETY, COGNITIVE FUNCTION, DEPRESSION, STRESS, QUALITY OF LIFE) IN ADULTS TREATED FOR CANCER. TO REDUCE PUBLICATION BIAS, IMPROVE REPRODUCIBILITY, AND SERVE AS A REFERENCE FOR FORTHCOMING REPORTING OF STUDY RESULTS, WE PRESENT THE STUDY PROTOCOL FOR THIS STUDY HEREIN. METHODS: PARTICIPANTS WERE ADULTS WHO COMPLETED CANCER TREATMENT THAT WERE RECRUITED FROM THE OTTAWA INTEGRATIVE CANCER CENTRE. CONSENTING AND ELIGIBLE PARTICIPANTS RECEIVED ONE 1:1 YOGA THERAPY SESSION (IE, 1 PARTICIPANT, 1 YOGA THERAPIST) AND 6 WEEKLY GROUP-BASED YOGA THERAPY SESSIONS (IE, 2-3 PARTICIPANTS, 1 YOGA THERAPIST). PARTICIPANTS COMPLETED ASSESSMENTS 7 TIMES: 3 TIMES PRIOR TO THE PROGRAM (IE, -6 WEEKS, -3 WEEKS, IMMEDIATELY PRIOR TO THE 1:1 YOGA THERAPY SESSION), IMMEDIATELY FOLLOWING THE 1:1 YOGA THERAPY SESSION, PRIOR TO THE FIRST GROUP-BASED YOGA THERAPY SESSION, AFTER THE LAST GROUP-BASED YOGA THERAPY SESSION, AND AT A 6-WEEK FOLLOW-UP. HIERARCHICAL LINEAR MODELING WILL BE USED TO TEST THE AVERAGE EFFECTS OF THE YOGA THERAPY PROGRAM ACROSS PARTICIPANTS. DISCUSSION: THIS STUDY WILL EXPLORE SEVERAL NOVEL HYPOTHESES, INCLUDING WHETHER YOGA THERAPY CAN IMPROVE HRV AND/OR SPECIFIC PROS AMONG ADULTS TREATED FOR CANCER ACUTELY (IE, DURING A 1:1 YOGA THERAPY SESSION) AND/OR THROUGH REPEATED EXPOSURE (IE, AFTER COMPLETING 6 WEEKS OF GROUP-BASED YOGA THERAPY). ALTHOUGH THE FINDINGS WILL REQUIRE CONFIRMATION OR REFUTATION IN FUTURE TRIALS, THEY MAY PROVIDE INITIAL EVIDENCE THAT YT MAY BENEFIT ADULTS TREATED FOR CANCER.

7 2831  58 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. WE WILL ALSO ASSESS COST EFFECTIVENESS FROM THE PERSPECTIVES OF THE INDIVIDUAL, INSURERS, AND SOCIETY USING CLAIMS DATABASES, ELECTRONIC MEDICAL RECORDS, SELF-REPORT COST DATA, AND STUDY RECORDS. QUALITATIVE DATA FROM INTERVIEWS WILL ADD SUBJECTIVE DETAIL TO COMPLEMENT QUANTITATIVE DATA.

8 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	

9 2596  59 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.

10 1291  40 GROUP ACUPUNCTURE THERAPY WITH YOGA THERAPY FOR CHRONIC NECK, LOW BACK, AND OSTEOARTHRITIS PAIN IN SAFETY NET SETTING FOR AN UNDERSERVED POPULATION: DESIGN AND RATIONALE FOR A FEASIBILITY PILOT. CHRONIC PAIN IS PREVALENT IN THE UNITED STATES, WITH IMPACT ON PHYSICAL AND PSYCHOLOGICAL FUNCTIONING AS WELL AS LOST WORK PRODUCTIVITY. MINORITY AND LOWER SOCIOECONOMIC POPULATIONS HAVE INCREASED PREVALENCE OF CHRONIC PAIN WITH LESS ACCESS TO PAIN CARE, POORER OUTCOMES, AND HIGHER RISK OF FATAL OPIOID OVERDOSE. ACUPUNCTURE THERAPY IS EFFECTIVE IN TREATING CHRONIC PAIN CONDITIONS INCLUDING CHRONIC LOW BACK PAIN, NECK PAIN, SHOULDER PAIN, AND KNEE PAIN FROM OSTEOARTHRITIS. ACUPUNCTURE THERAPY, INCLUDING GROUP ACUPUNCTURE, IS FEASIBLE AND EFFECTIVE, AND SPECIFICALLY SO FOR UNDERSERVED AND DIVERSE POPULATIONS AT RISK FOR HEALTH OUTCOME DISPARITIES. ACUPUNCTURE THERAPY ALSO ENCOURAGES PATIENT ENGAGEMENT AND ACTIVATION. AS CHRONIC PAIN IMPROVES, THERE IS A NATURAL PROGRESSION TO WANT AND NEED TO INCREASE ACTIVITY AND MOVEMENT RECOVERY. DIVERSE MOVEMENT APPROACHES ARE IMPORTANT FOR IMPROVING RANGE OF MOTION, MAINTAINING GAINS, STRENGTHENING, AND PROMOTING PATIENT ENGAGEMENT AND ACTIVATION. YOGA THERAPY IS AN ACTIVE THERAPY WITH PROVEN BENEFIT IN MUSCULOSKELETAL PAIN DISORDERS AND PAIN ASSOCIATED DISABILITY. THE AIM OF THIS QUASI-EXPERIMENTAL PILOT FEASIBILITY TRIAL IS TO TEST THE BUNDLING OF THESE 2 EFFECTIVE CARE OPTIONS FOR CHRONIC PAIN, TO INFORM BOTH THE DESIGN FOR A LARGER RANDOMIZED PRAGMATIC EFFECTIVENESS TRIAL AS WELL AS IMPLEMENTATION STRATEGIES ACROSS UNDERSERVED SETTINGS.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
11 2851  59 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.

12  465  50 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
13  461  58 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
14 2560  68 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 1781  48 PREDICTORS OF AND BARRIERS TO ADHERENCE IN A 16-WEEK RANDOMISED CONTROLLED TRIAL OF BIKRAM YOGA IN STRESSED AND SEDENTARY ADULTS. BACKGROUND: BIKRAM YOGA MAY ENHANCE HEALTH OUTCOMES IN HEALTHY ADULTS AND THOSE AT RISK FOR CHRONIC DISEASE, HOWEVER, CHALLENGES REMAIN IN ACHIEVING OPTIMAL ADHERENCE TO THIS PRACTICE. THIS STUDY INVESTIGATED FACTORS INFLUENCING ADHERENCE TO A 16-WEEK BIKRAM YOGA INTERVENTION IN STRESSED AND SEDENTARY ADULTS. METHODS: EXPERIMENTAL GROUP PARTICIPANTS (N = 29) WERE INSTRUCTED TO ATTEND 3-5 BIKRAM YOGA CLASSES WEEKLY FOR 16 WEEKS. BASELINE DEMOGRAPHICS, BEHAVIOURS AND HEALTH MEASURES WERE INVESTIGATED AS PREDICTORS OF ADHERENCE. BARRIERS WERE ASSESSED VIA DOCUMENTATION OF ADVERSE EVENTS, AND EXIT SURVEY RESPONSES. RESULTS: PARTICIPANTS (38.2 +/- 10.1 YEARS) WERE PREDOMINANTLY OVERWEIGHT-OBESE (83%), FEMALE (79%), AND ATTENDED 27 +/- 18 CLASSES. HIGHER ADHERENCE WAS ASSOCIATED WITH OLDER AGE (P = 0.094), LESS PAIN (P = 0.011), FEWER PHYSICAL LIMITATIONS (P = 0.011), POORER BLOOD LIPID PROFILE, AND HIGHER HEART RATE VARIABILITY (HRV; TOTAL POWER, (P = 0.097)). IN MULTI-VARIABLE ANALYSIS, THREE VARIABLES: AGE (BETA = 0.492, P = 0.006), HRV (BETA = 0.413, P = 0.021) AND PAIN (BETA = 0.329, P = 0.048) REMAINED PREDICTORS OF ADHERENCE. DIFFICULTY COMMITTING TO THE TRIAL, LACK OF ENJOYMENT AND ADVERSE EVENTS WERE BARRIERS TO ADHERENCE. CONCLUSIONS: THESE FINDINGS SHOULD BE CONSIDERED IN THE DEVELOPMENT OF FUTURE BIKRAM YOGA TRIALS TO FACILITATE HIGHER LEVELS OF ADHERENCE, WHICH MAY ENHANCE HEALTH OUTCOMES AND INFORM COMMUNITY PRACTICE. FUTURE TRIALS SHOULD INVESTIGATE AND ADDRESS ADDITIONAL BARRIERS AND FACILITATORS OF BIKRAM YOGA PRACTICE.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
16  162  59 A RANDOMISED CONTROLLED TRIAL OF YOGA FOR THE TREATMENT OF CHRONIC LOW BACK PAIN: RESULTS OF A PILOT STUDY. OBJECTIVE: TO CONDUCT A PILOT TRIAL OF YOGA FOR THE TREATMENT OF CHRONIC LOW BACK PAIN (LBP) TO INFORM THE FEASIBILITY AND PRACTICALITY OF CONDUCTING A FULL-SCALE TRIAL IN THE UK; AND TO ASSESS THE EFFICACY OF YOGA FOR THE TREATMENT OF CHRONIC LOW BACK PAIN. DESIGN: A PRAGMATIC RANDOMISED CONTROLLED TRIAL WAS UNDERTAKEN COMPARING YOGA TO USUAL CARE. PARTICIPANTS: TWENTY PARTICIPANTS WHO HAD PRESENTED TO THEIR GP WITH CHRONIC LOW BACK PAIN IN THE PREVIOUS 18 MONTHS WERE RECRUITED VIA GP RECORDS FROM ONE PRACTICE IN YORK, UK. INTERVENTIONS: TWENTY PATIENTS WERE RANDOMISED TO EITHER 12 WEEKLY 75-MIN SESSIONS OF SPECIALISED YOGA PLUS WRITTEN ADVICE, OR USUAL CARE PLUS WRITTEN ADVICE. ALLOCATION WAS 50/50. MAIN OUTCOME MEASURES: RECRUITMENT RATE, LEVELS OF INTERVENTION ATTENDANCE, AND LOSS TO FOLLOW-UP WERE THE MAIN NON-CLINICAL OUTCOMES. CHANGE AS MEASURED BY THE ROLAND AND MORRIS DISABILITY QUESTIONNAIRE WAS THE PRIMARY CLINICAL OUTCOME. CHANGES IN THE ABERDEEN BACK PAIN SCALE, SF-12, EQ-5D, AND PAIN SELF-EFFICACY WERE SECONDARY CLINICAL OUTCOMES. DATA WERE COLLECTED VIA POSTAL QUESTIONNAIRE AT BASELINE, 4 WEEKS, AND 12 WEEKS FOLLOW-UP. RESULTS: OF THE 286 PATIENTS IDENTIFIED FROM THE GP DATABASE, 52 (18%) CONSENTED AND RETURNED THE ELIGIBILITY QUESTIONNAIRE, OUT OF THESE 20 (6.9%) WERE ELIGIBLE AND RANDOMISED. THE TOTAL PERCENTAGE OF PATIENTS RANDOMISED FROM THE GP PRACTICE POPULATION WAS 0.28%. TEN PATIENTS WERE RANDOMISED TO YOGA, RECEIVING AN AVERAGE OF 1.7 SESSIONS (RANGE 0-5), AND 10 WERE RANDOMISED TO USUAL CARE. AT 12 WEEKS FOLLOW-UP DATA WAS RECEIVED FROM 60% OF PATIENTS IN THE YOGA GROUP AND 90% OF PATIENTS IN THE USUAL CARE GROUP (75% OVERALL). NO SIGNIFICANT DIFFERENCES WERE SEEN BETWEEN GROUPS IN CLINICAL OUTCOMES APART FROM ON THE ABERDEEN BACK PAIN SCALE AT FOUR WEEKS FOLLOW-UP WHERE THE YOGA GROUP REPORTED SIGNIFICANTLY LESS PAIN. CONCLUSION: THIS PILOT STUDY PROVIDED USEFUL DATA AND INFORMATION TO INFORM THE DESIGN AND DEVELOPMENT OF A FULL-SCALE TRIAL OF YOGA FOR CLBP IN THE UK. A KEY FINDING IS THE CALCULATION OF GP PRACTICE TOTAL LIST SIZE REQUIRED FOR PATIENT RECRUITMENT IN A FULL-SCALE TRIAL, AND THE NEED TO IMPLEMENT METHODS TO INCREASE CLASS ATTENDANCE.	2010	
                                                                                                                                                                                                                                                                                                                                                              
17  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.

18   74  49 A GROUP-BASED YOGA THERAPY INTERVENTION FOR URINARY INCONTINENCE IN WOMEN: A PILOT RANDOMIZED TRIAL. OBJECTIVE: THE AIM OF THIS STUDY IS TO EXAMINE THE FEASIBILITY, EFFICACY, AND SAFETY OF A GROUP-BASED YOGA THERAPY INTERVENTION FOR MIDDLE-AGED AND OLDER WOMEN WITH URINARY INCONTINENCE. METHODS: WE CONDUCTED A PILOT RANDOMIZED TRIAL OF AMBULATORY WOMEN AGED 40 YEARS AND OLDER WITH STRESS, URGENCY, OR MIXED-TYPE INCONTINENCE. WOMEN WERE RANDOMIZED TO A 6-WEEK YOGA THERAPY PROGRAM (N = 10) CONSISTING OF TWICE WEEKLY GROUP CLASSES AND ONCE WEEKLY HOME PRACTICE OR A WAIT-LIST CONTROL GROUP (N = 9). ALL PARTICIPANTS ALSO RECEIVED WRITTEN PAMPHLETS ABOUT STANDARD BEHAVIORAL SELF-MANAGEMENT STRATEGIES FOR INCONTINENCE. CHANGES IN INCONTINENCE WERE ASSESSED WITH 7-DAY VOIDING DIARIES. RESULTS: THE MEAN (SD) AGE WAS 61.4 (8.2) YEARS, AND THE MEAN BASELINE FREQUENCY OF INCONTINENCE WAS 2.5 (1.3) EPISODES/D. AFTER 6 WEEKS, THE TOTAL INCONTINENCE FREQUENCY DECREASED BY 70% (1.8 [0.9] FEWER EPISODES/D) IN THE YOGA THERAPY VERSUS 13% (0.3 [1.7] FEWER EPISODES/D) IN THE CONTROL GROUP (P = 0.049). PARTICIPANTS IN THE YOGA THERAPY GROUP ALSO REPORTED AN AVERAGE OF 71% DECREASE IN STRESS INCONTINENCE FREQUENCY (0.7 [0.8] FEWER EPISODES/D) COMPARED WITH A 25% INCREASE IN CONTROLS (0.2 [1.1] MORE EPISODES/D) (P = 0.039). NO SIGNIFICANT DIFFERENCES IN REDUCTION IN URGENCY INCONTINENCE WERE DETECTED BETWEEN THE YOGA THERAPY VERSUS CONTROL GROUPS (1.0 [1.0] VERSUS 0.5 [0.5] FEWER EPISODES/D; P = 0.20). ALL WOMEN STARTING THE YOGA THERAPY PROGRAM COMPLETED AT LEAST 90% OF THE GROUP CLASSES AND PRACTICE SESSIONS. TWO PARTICIPANTS IN EACH GROUP REPORTED ADVERSE EVENTS UNRELATED TO THE INTERVENTION. CONCLUSIONS: FINDINGS PROVIDE PRELIMINARY EVIDENCE TO SUPPORT THE FEASIBILITY, EFFICACY, AND SAFETY OF A GROUP-BASED YOGA THERAPY INTERVENTION TO IMPROVE URINARY INCONTINENCE IN WOMEN.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
19 2824  54 YOGA VERSUS EDUCATION FOR VETERANS WITH CHRONIC LOW BACK PAIN: STUDY PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN IS THE MOST FREQUENT PAIN CONDITION IN VETERANS AND CAUSES SUBSTANTIAL SUFFERING, DECREASED FUNCTIONAL CAPACITY, AND LOWER QUALITY OF LIFE. SYMPTOMS OF POST-TRAUMATIC STRESS, DEPRESSION, AND MILD TRAUMATIC BRAIN INJURY ARE HIGHLY PREVALENT IN VETERANS WITH BACK PAIN. YOGA FOR LOW BACK PAIN HAS BEEN DEMONSTRATED TO BE EFFECTIVE FOR CIVILIANS IN RANDOMIZED CONTROLLED TRIALS. HOWEVER, IT IS UNKNOWN IF RESULTS FROM PREVIOUSLY PUBLISHED TRIALS GENERALIZE TO MILITARY POPULATIONS. METHODS/DESIGN: THIS STUDY IS A PARALLEL RANDOMIZED CONTROLLED TRIAL COMPARING YOGA TO EDUCATION FOR 120 VETERANS WITH CHRONIC LOW BACK PAIN. PARTICIPANTS ARE VETERANS >/=18 YEARS OLD WITH LOW BACK PAIN PRESENT ON AT LEAST HALF THE DAYS IN THE PAST SIX MONTHS AND A SELF-REPORTED AVERAGE PAIN INTENSITY IN THE PREVIOUS WEEK OF >/=4 ON A 0-10 SCALE. THE 24-WEEK STUDY HAS AN INITIAL 12-WEEK INTERVENTION PERIOD, WHERE PARTICIPANTS ARE RANDOMIZED EQUALLY INTO (1) A STANDARDIZED WEEKLY GROUP YOGA CLASS WITH HOME PRACTICE OR (2) EDUCATION DELIVERED WITH A SELF-CARE BOOK. PRIMARY OUTCOME MEASURES ARE CHANGE AT 12 WEEKS IN LOW BACK PAIN INTENSITY MEASURED BY THE DEFENSE AND VETERANS PAIN RATING SCALE (0-10) AND BACK-RELATED FUNCTION USING THE 23-POINT ROLAND MORRIS DISABILITY QUESTIONNAIRE. IN THE SUBSEQUENT 12-WEEK FOLLOW-UP PERIOD, YOGA PARTICIPANTS ARE ENCOURAGED TO CONTINUE HOME YOGA PRACTICE AND EDUCATION PARTICIPANTS CONTINUE FOLLOWING RECOMMENDATIONS FROM THE BOOK. QUALITATIVE INTERVIEWS WITH VETERANS IN THE YOGA GROUP AND THEIR PARTNERS EXPLORE THE IMPACT OF CHRONIC LOW BACK PAIN AND YOGA ON FAMILY RELATIONSHIPS. WE ALSO ASSESS COST-EFFECTIVENESS FROM THREE PERSPECTIVES: THE VETERAN, THE VETERANS HEALTH ADMINISTRATION, AND SOCIETY USING ELECTRONIC MEDICAL RECORDS, SELF-REPORTED COST DATA, AND STUDY RECORDS. DISCUSSION: THIS STUDY WILL HELP DETERMINE IF YOGA CAN BECOME AN EFFECTIVE TREATMENT FOR VETERANS WITH CHRONIC LOW BACK PAIN AND PSYCHOLOGICAL COMORBIDITIES.

20  521  63 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
