1  193 125 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.

2 1699  50 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
3  521  81 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
4 1870  44 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
5 1180  46 EVALUATION OF THE EFFECTIVENESS AND EFFICACY OF IYENGAR YOGA THERAPY ON CHRONIC LOW BACK PAIN. STUDY DESIGN: THE EFFECTIVENESS AND EFFICACY OF IYENGAR YOGA FOR CHRONIC LOW BACK PAIN (CLBP) WERE ASSESSED WITH INTENTION-TO-TREAT AND PER-PROTOCOL ANALYSIS. NINETY SUBJECTS WERE RANDOMIZED TO A YOGA (N = 43) OR CONTROL GROUP (N = 47) RECEIVING STANDARD MEDICAL CARE. PARTICIPANTS WERE FOLLOWED 6 MONTHS AFTER COMPLETION OF THE INTERVENTION. OBJECTIVE: THIS STUDY AIMED TO EVALUATE IYENGAR YOGA THERAPY ON CHRONIC LOW BACK PAIN. YOGA SUBJECTS WERE HYPOTHESIZED TO REPORT GREATER REDUCTIONS IN FUNCTIONAL DISABILITY, PAIN INTENSITY, DEPRESSION, AND PAIN MEDICATION USAGE THAN CONTROLS. SUMMARY OF BACKGROUND DATA: CLBP IS A MUSCULOSKELETAL DISORDER WITH PUBLIC HEALTH AND ECONOMIC IMPACT. PILOT STUDIES OF YOGA AND BACK PAIN HAVE REPORTED SIGNIFICANT CHANGES IN CLINICALLY IMPORTANT OUTCOMES. METHODS: SUBJECTS WERE RECRUITED THROUGH SELF-REFERRAL AND HEALTH PROFESSIONAL REFERRALS ACCORDING TO EXPLICIT INCLUSION/EXCLUSION CRITERIA. YOGA SUBJECTS PARTICIPATED IN 24 WEEKS OF BIWEEKLY YOGA CLASSES DESIGNED FOR CLBP. OUTCOMES WERE ASSESSED AT 12 (MIDWAY), 24 (IMMEDIATELY AFTER), AND 48 WEEKS (6-MONTH FOLLOW-UP) AFTER THE START OF THE INTERVENTION USING THE OSWESTRY DISABILITY QUESTIONNAIRE, A VISUAL ANALOG SCALE, THE BECK DEPRESSION INVENTORY, AND A PAIN MEDICATION-USAGE QUESTIONNAIRE. RESULTS: USING INTENTION-TO-TREAT ANALYSIS WITH REPEATED MEASURES ANOVA (GROUP X TIME), SIGNIFICANTLY GREATER REDUCTIONS IN FUNCTIONAL DISABILITY AND PAIN INTENSITY WERE OBSERVED IN THE YOGA GROUP WHEN COMPARED TO THE CONTROL GROUP AT 24 WEEKS. A SIGNIFICANTLY GREATER PROPORTION OF YOGA SUBJECTS ALSO REPORTED CLINICAL IMPROVEMENTS AT BOTH 12 AND 24 WEEKS. IN ADDITION, DEPRESSION WAS SIGNIFICANTLY LOWER IN YOGA SUBJECTS. FURTHERMORE, WHILE A REDUCTION IN PAIN MEDICATION OCCURRED, THIS WAS COMPARABLE IN BOTH GROUPS. WHEN RESULTS WERE ANALYZED USING PER-PROTOCOL ANALYSIS, IMPROVEMENTS WERE OBSERVED FOR ALL OUTCOMES IN THE YOGA GROUP, INCLUDING AGREATER TREND FOR REDUCED PAIN MEDICATION USAGE. ALTHOUGH SLIGHTLY LESS THAN AT 24 WEEKS, THE YOGA GROUP HAD STATISTICALLY SIGNIFICANT REDUCTIONS IN FUNCTIONAL DISABILITY, PAIN INTENSITY, AND DEPRESSION COMPARED TO STANDARD MEDICAL CARE 6-MONTHS POSTINTERVENTION. CONCLUSION: YOGA IMPROVES FUNCTIONAL DISABILITY, PAIN INTENSITY, AND DEPRESSION IN ADULTS WITH CLBP. THERE WAS ALSO A CLINICALLY IMPORTANT TREND FOR THE YOGA GROUP TO REDUCE THEIR PAIN MEDICATION USAGE COMPARED TO THE CONTROL GROUP.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
6 1787  49 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
7 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.

8  518  56 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.

9  721  38 EFFECT OF IYENGAR YOGA THERAPY FOR CHRONIC LOW BACK PAIN. LOW BACK PAIN IS A SIGNIFICANT PUBLIC HEALTH PROBLEM AND ONE OF THE MOST COMMONLY REPORTED REASONS FOR THE USE OF COMPLEMENTARY ALTERNATIVE MEDICINE. A RANDOMIZED CONTROL TRIAL WAS CONDUCTED IN SUBJECTS WITH NON-SPECIFIC CHRONIC LOW BACK PAIN COMPARING IYENGAR YOGA THERAPY TO AN EDUCATIONAL CONTROL GROUP. BOTH PROGRAMS WERE 16 WEEKS LONG. SUBJECTS WERE PRIMARILY SELF-REFERRED AND SCREENED BY PRIMARY CARE PHYSICIANS FOR STUDY OF INCLUSION/EXCLUSION CRITERIA. THE PRIMARY OUTCOME FOR THE STUDY WAS FUNCTIONAL DISABILITY. SECONDARY OUTCOMES INCLUDING PRESENT PAIN INTENSITY, PAIN MEDICATION USAGE, PAIN-RELATED ATTITUDES AND BEHAVIORS, AND SPINAL RANGE OF MOTION WERE MEASURED BEFORE AND AFTER THE INTERVENTIONS. SUBJECTS HAD LOW BACK PAIN FOR 11.2+/-1.54 YEARS AND 48% USED PAIN MEDICATION. OVERALL, SUBJECTS PRESENTED WITH LESS PAIN AND LOWER FUNCTIONAL DISABILITY THAN SUBJECTS IN OTHER PUBLISHED INTERVENTION STUDIES FOR CHRONIC LOW BACK PAIN. OF THE 60 SUBJECTS ENROLLED, 42 (70%) COMPLETED THE STUDY. MULTIVARIATE ANALYSES OF OUTCOMES IN THE CATEGORIES OF MEDICAL, FUNCTIONAL, PSYCHOLOGICAL AND BEHAVIORAL FACTORS INDICATED THAT SIGNIFICANT DIFFERENCES BETWEEN GROUPS EXISTED IN FUNCTIONAL AND MEDICAL OUTCOMES BUT NOT FOR THE PSYCHOLOGICAL OR BEHAVIORAL OUTCOMES. UNIVARIATE ANALYSES OF MEDICAL AND FUNCTIONAL OUTCOMES REVEALED SIGNIFICANT REDUCTIONS IN PAIN INTENSITY (64%), FUNCTIONAL DISABILITY (77%) AND PAIN MEDICATION USAGE (88%) IN THE YOGA GROUP AT THE POST AND 3-MONTH FOLLOW-UP ASSESSMENTS. THESE PRELIMINARY DATA INDICATE THAT THE MAJORITY OF SELF-REFERRED PERSONS WITH MILD CHRONIC LOW BACK PAIN WILL COMPLY TO AND REPORT IMPROVEMENT ON MEDICAL AND FUNCTIONAL PAIN-RELATED OUTCOMES FROM IYENGAR YOGA THERAPY.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
10 2824  51 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.

11 2560  51 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.

12 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
13 1953  47 SECONDARY OUTCOMES FROM A RANDOMIZED CONTROLLED TRIAL OF YOGA FOR VETERANS WITH CHRONIC LOW-BACK PAIN. CHRONIC LOW-BACK PAIN (CLBP) IS A PREVALENT CONDITION, AND RATES ARE HIGHER AMONG MILITARY VETERANS. CLBP IS A PERSISTENT CONDITION, AND TREATMENT OPTIONS HAVE EITHER MODEST EFFECTS OR A SIGNIFICANT RISK OF SIDE-EFFECTS, WHICH HAS LED TO RECENT EFFORTS TO EXPLORE MIND-BODY INTERVENTION OPTIONS AND REDUCE OPIOID MEDICATION USE. PRIOR STUDIES OF YOGA FOR CLBP IN COMMUNITY SAMPLES, AND THE MAIN RESULTS OF A RECENT TRIAL WITH MILITARY VETERANS, INDICATE THAT YOGA CAN REDUCE BACK-RELATED DISABILITY AND PAIN INTENSITY. SECONDARY OUTCOMES FROM THE TRIAL OF YOGA WITH MILITARY VETERANS ARE PRESENTED HERE. IN THE STUDY, 150 MILITARY VETERANS (VETERANS ADMINISTRATION PATIENTS) WITH CLBP WERE RANDOMIZED TO EITHER YOGA OR A DELAYED-TREATMENT GROUP RECEIVING USUAL CARE BETWEEN 2013 AND 2015. ASSESSMENTS OCCURRED AT BASELINE, 6 WEEKS, 12 WEEKS, AND 6 MONTHS. INTENT-TO-TREAT ANALYSES WERE CONDUCTED. YOGA CLASSES LASTING 60 MINUTES EACH WERE OFFERED TWICE WEEKLY FOR 12 WEEKS. YOGA SESSIONS CONSISTED OF PHYSICAL POSTURES, MOVEMENT, FOCUSED ATTENTION, AND BREATHING TECHNIQUES. HOME PRACTICE GUIDED BY A MANUAL WAS STRONGLY RECOMMENDED. THE PRIMARY OUTCOME MEASURE WAS ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES AFTER 12 WEEKS. SECONDARY OUTCOMES INCLUDED PAIN INTENSITY, PAIN INTERFERENCE, DEPRESSION, FATIGUE, QUALITY OF LIFE, SELF-EFFICACY, AND MEDICATION USAGE. YOGA PARTICIPANTS IMPROVED MORE THAN DELAYED-TREATMENT PARTICIPANTS ON PAIN INTERFERENCE, FATIGUE, QUALITY OF LIFE, AND SELF-EFFICACY AT 12 WEEKS AND/OR 6 MONTHS. YOGA PARTICIPANTS HAD GREATER IMPROVEMENTS ACROSS A NUMBER OF IMPORTANT SECONDARY HEALTH OUTCOMES COMPARED TO CONTROLS. BENEFITS EMERGED DESPITE SOME VETERANS FACING CHALLENGES WITH ATTENDING YOGA SESSIONS IN PERSON. THE FINDINGS SUPPORT WIDER IMPLEMENTATION OF YOGA PROGRAMS FOR VETERANS, WITH ATTENTION TO INCREASING ACCESSIBILITY OF YOGA PROGRAMS IN THIS POPULATION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
14 2845  43 YOGA, EURYTHMY THERAPY AND STANDARD PHYSIOTHERAPY (YES-TRIAL) FOR PATIENTS WITH CHRONIC NON-SPECIFIC LOW BACK PAIN: A THREE-ARMED RANDOMIZED CONTROLLED TRIAL. WE AIMED TO EVALUATE THE EFFECTS OF YOGA AND EURYTHMY THERAPY COMPARED TO CONVENTIONAL PHYSIOTHERAPY EXERCISES IN PATIENTS WITH CHRONIC LOW BACK PAIN. IN A THREE-ARMED, MULTICENTRE, RANDOMIZED CONTROLLED TRIAL, PATIENTS WITH CHRONIC LOW BACK PAIN WERE TREATED FOR 8 WEEKS IN GROUP SESSIONS (75 MINUTES ONCE PER WEEK). PRIMARY OUTCOME WAS PATIENTS' PHYSICAL DISABILITY (MEASURED BY RMDQ) FROM BASELINE TO WEEK 8. SECONDARY OUTCOME VARIABLES WERE PAIN INTENSITY AND PAIN-RELATED BOTHERSOMENESS (VAS), HEALTH-RELATED QUALITY OF LIFE (SF-12) AND LIFE SATISFACTION (BMLSS). OUTCOMES WERE ASSESSED AT BASELINE, AFTER THE INTERVENTION AT 8 WEEKS AND AT A 16-WEEK FOLLOW UP. DATA OF 274 PARTICIPANTS WERE USED FOR STATISTICAL ANALYSES. THERE WERE NO SIGNIFICANT DIFFERENCES BETWEEN THE THREE GROUPS FOR THE PRIMARY AND ALL SECONDARY OUTCOMES. IN ALL GROUPS, RMDQ DECREASED COMPARABLY AT 8 WEEKS, BUT DID NOT REACH CLINICAL MEANINGFULNESS. PAIN INTENSITY AND PAIN-RELATED BOTHERSOMENESS DECREASED, WHILE QUALITY OF LIFE INCREASED IN ALL 3 GROUPS. IN EXPLORATIVE GENERAL LINEAR MODELS FOR THE SF-12'S MENTAL HEALTH COMPONENT PARTICIPANTS IN THE EURYTHMY ARM BENEFITTED SIGNIFICANTLY MORE COMPARED TO PHYSIOTHERAPY AND YOGA. FURTHERMORE, WITHIN-GROUP ANALYSES SHOWED IMPROVEMENTS OF SF-12 MENTAL SCORE FOR YOGA AND EURYTHMY THERAPY ONLY. ALL INTERVENTIONS WERE SAFE. CLINICAL TRIALS REGISTER: DRKS-ID: DRKS00004651 PERSPECTIVE: THIS ARTICLE PRESENTS THE RESULTS OF A MULTICENTRE THREE-ARMED RANDOMIZED CONTROLLED TRIAL ON THE CLINICAL EFFECTS OF THREE 8-WEEK PROGRAMS IN PATIENTS WITH CHRONIC LOW BACK PAIN. COMPARED TO THE 'GOLD STANDARD' OF CONVENTIONAL PHYSIOTHERAPEUTIC EXERCISES, EURYTHMY THERAPY AND YOGA THERAPY LEAD TO COMPARABLE SYMPTOMATIC IMPROVEMENTS IN PATIENTS WITH CHRONIC LOW BACK PAIN. HOWEVER, THE WITHIN-GROUP EFFECT SIZES WERE SMALL TO MODERATE AND DID NOT REACH CLINICAL MEANINGFULNESS ON PATIENTS' PHYSICAL DISABILITY (RMDQ).	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15 2558  56 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 1488  41 INTER-METHOD RELIABILITY OF PAPER SURVEYS AND COMPUTER ASSISTED TELEPHONE INTERVIEWS IN A RANDOMIZED CONTROLLED TRIAL OF YOGA FOR LOW BACK PAIN. BACKGROUND: LITTLE IS KNOWN ABOUT THE RELIABILITY OF DIFFERENT METHODS OF SURVEY ADMINISTRATION IN LOW BACK PAIN TRIALS. THIS ANALYSIS WAS DESIGNED TO DETERMINE THE RELIABILITY OF RESPONSES TO SELF-ADMINISTERED PAPER SURVEYS COMPARED TO COMPUTER ASSISTED TELEPHONE INTERVIEWS (CATI) FOR THE PRIMARY OUTCOMES OF PAIN INTENSITY AND BACK-RELATED FUNCTION, AND SECONDARY OUTCOMES OF PATIENT SATISFACTION, SF-36, AND GLOBAL IMPROVEMENT AMONG PARTICIPANTS ENROLLED IN A STUDY OF YOGA FOR CHRONIC LOW BACK PAIN. RESULTS: PAIN INTENSITY, BACK-RELATED FUNCTION, AND BOTH PHYSICAL AND MENTAL HEALTH COMPONENTS OF THE SF-36 SHOWED EXCELLENT RELIABILITY AT ALL THREE TIME POINTS; ICC SCORES RANGED FROM 0.82 TO 0.98. PAIN MEDICATION USE SHOWED GOOD RELIABILITY; KAPPA STATISTICS RANGED FROM 0.68 TO 0.78. PATIENT SATISFACTION HAD MODERATE TO EXCELLENT RELIABILITY; ICC SCORES RANGED FROM 0.40 TO 0.86. GLOBAL IMPROVEMENT SHOWED POOR RELIABILITY AT 6 WEEKS (ICC = 0.24) AND 12 WEEKS (ICC = 0.10). CONCLUSION: CATI SHOWS EXCELLENT RELIABILITY FOR PRIMARY OUTCOMES AND AT LEAST SOME SECONDARY OUTCOMES WHEN COMPARED TO SELF-ADMINISTERED PAPER SURVEYS IN A LOW BACK PAIN YOGA TRIAL. HAVING TWO RELIABLE OPTIONS FOR DATA COLLECTION MAY BE HELPFUL TO INCREASE RESPONSE RATES FOR CORE OUTCOMES IN BACK PAIN TRIALS. TRIAL REGISTRATION: CLINICALTRIALS.GOV: NCT01761617.

17  465  47 CHARACTERISTICS AND PREDICTORS OF SHORT-TERM OUTCOMES IN INDIVIDUALS SELF-SELECTING YOGA OR PHYSICAL THERAPY FOR TREATMENT OF CHRONIC LOW BACK PAIN. OBJECTIVE: TO COMPARE CLINICAL AND DEMOGRAPHIC CHARACTERISTICS OF INDIVIDUALS SELF-SELECTING YOGA OR PHYSICAL THERAPY (PT) FOR TREATMENT OF CHRONIC LOW BACK PAIN (CLBP) AND TO EXAMINE PREDICTORS OF SHORT-TERM PAIN AND FUNCTIONAL OUTCOMES. DESIGN: DESCRIPTIVE, LONGITUDINAL STUDY. SETTINGS: A HOSPITAL-BASED CLINIC THAT OFFERS MODIFIED INTEGRAL YOGA CLASSES FOR CLBP AND 2 OUTPATIENT PT CLINICS THAT OFFER EXERCISE-BASED PT. PARTICIPANTS: ADULTS (N=53) WITH CLBP>/=12 WEEKS: YOGA (N=27), PT (N=26). METHODS: YOGA PARTICIPANTS ATTENDED A 6-WEEK, ONCE WEEKLY, 2-HOUR YOGA CLASS. PT PARTICIPANTS UNDERWENT TWICE WEEKLY, 1-HOUR INDIVIDUALIZED PT. DATA WERE COLLECTED AT BASELINE AND AT 6 WEEKS. GROUPS WERE COMPARED BY USING CHI2 AND INDEPENDENT SAMPLES T-TESTS. HIERARCHICAL LINEAR REGRESSION WAS USED TO PREDICT TREATMENT OUTCOMES. MAIN OUTCOME MEASURES: DISABILITY (ROLAND MORRIS DISABILITY QUESTIONNAIRE), HEALTH STATUS (RAND SHORT FORM 36 HEALTH SURVEY 1.0), PAIN BOTHERSOMENESS (NUMERICAL RATING SCALE), BACK PAIN SELF-EFFICACY (BACK PAIN SELF-EFFICACY SCALE), AND TREATMENT SATISFACTION. RESULTS: AT BASELINE, YOGA PARTICIPANTS WERE SIGNIFICANTLY LESS DISABLED (P=.013), HAD HIGHER HEALTH STATUS (P=.023), GREATER PAIN SELF-EFFICACY (P=.012), AND LESS AVERAGE PAIN BOTHERSOMENESS (P=.001) COMPARED WITH PT PARTICIPANTS. AT 6 WEEKS, WHEN CONTROLLING FOR BASELINE GROUP DIFFERENCES, GREATER PAIN SELF-EFFICACY WAS THE STRONGEST PREDICTOR FOR REDUCED PAIN AND HIGHER FUNCTION FOR THE ENTIRE SAMPLE. A SIGNIFICANT GROUP INTERACTION BY BASELINE PAIN SELF-EFFICACY PREDICTED DISABILITY AT 6 WEEKS. PT PARTICIPANTS WITH LOW PAIN SELF-EFFICACY REPORTED SIGNIFICANTLY GREATER DISABILITY THAN THOSE WITH HIGH PAIN SELF-EFFICACY. YOGA PARTICIPANTS WITH LOW AND HIGH PAIN SELF-EFFICACY HAD SIMILAR DISABILITY OUTCOMES. CONCLUSION: THESE FINDINGS STRENGTHEN EVIDENCE THAT SELF-EFFICACY IS ASSOCIATED WITH CLBP OUTCOMES, ESPECIALLY IN INDIVIDUALS SELF-SELECTING PT. FURTHER RESEARCH TO EVALUATE OUTCOMES AFTER YOGA AND PT IN PARTICIPANTS WITH LOW PAIN SELF-EFFICACY IS NEEDED.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
18 2518  57 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	

19  162  48 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20  388  41 BENEFITS OF THE RESTORATIVE EXERCISE AND STRENGTH TRAINING FOR OPERATIONAL RESILIENCE AND EXCELLENCE YOGA PROGRAM FOR CHRONIC LOW BACK PAIN IN SERVICE MEMBERS: A PILOT RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: TO EXAMINE THE FEASIBILITY AND PRELIMINARY EFFECTIVENESS OF AN INDIVIDUALIZED YOGA PROGRAM. DESIGN: PILOT RANDOMIZED CONTROLLED TRIAL. SETTING: MILITARY MEDICAL CENTER. PARTICIPANTS: PATIENTS (N=68) WITH CHRONIC LOW BACK PAIN. INTERVENTIONS: RESTORATIVE EXERCISE AND STRENGTH TRAINING FOR OPERATIONAL RESILIENCE AND EXCELLENCE (RESTORE) PROGRAM (9-12 INDIVIDUAL YOGA SESSIONS) OR TREATMENT AS USUAL (CONTROL) FOR AN 8-WEEK PERIOD. MAIN OUTCOME MEASURES: THE PRIMARY OUTCOME WAS PAST 24-HOUR PAIN (DEFENSE & VETERANS PAIN RATING SCALE 2.0). SECONDARY OUTCOMES INCLUDED DISABILITY (ROLAND-MORRIS DISABILITY QUESTIONNAIRE) AND PHYSICAL FUNCTIONING AND SYMPTOM BURDEN (PATIENT-REPORTED OUTCOMES MEASUREMENT INFORMATION SYSTEM-29 SUBSCALES). ASSESSMENT OCCURRED AT BASELINE, WEEK 4, WEEK 8, 3-MONTH FOLLOW-UP, AND 6-MONTH FOLLOW-UP. EXPLORATORY OUTCOMES INCLUDED THE PROPORTION OF PARTICIPANTS IN EACH GROUP REPORTING CLINICALLY MEANINGFUL CHANGES AT 3- AND 6-MONTH FOLLOW-UPS. RESULTS: GENERALIZED LINEAR MIXED MODELS WITH SEQUENTIAL BONFERRONI-ADJUSTED PAIRWISE SIGNIFICANCE TESTS AND CHI-SQUARE ANALYSES EXAMINED LONGITUDINAL OUTCOMES. SECONDARY OUTCOME SIGNIFICANCE TESTS WERE BONFERRONI ADJUSTED FOR MULTIPLE OUTCOMES. THE RESTORE GROUP REPORTED IMPROVED PAIN COMPARED WITH THE CONTROL GROUP. SECONDARY OUTCOMES DID NOT RETAIN SIGNIFICANCE AFTER BONFERRONI ADJUSTMENTS FOR MULTIPLE OUTCOMES, ALTHOUGH A HIGHER PROPORTION OF RESTORE PARTICIPANTS REPORTED CLINICALLY MEANINGFULLY CHANGES IN ALL OUTCOMES AT 3-MONTH FOLLOW-UP AND IN SYMPTOM BURDEN AT 6-MONTH FOLLOW-UP. CONCLUSIONS: RESTORE MAY BE A VIABLE NONPHARMACOLOGICAL TREATMENT FOR LOW BACK PAIN WITH MINIMAL SIDE EFFECTS, AND RESEARCH EFFORTS ARE NEEDED TO COMPARE THE EFFECTIVENESS OF RESTORE DELIVERY FORMATS (EG, GROUP VS INDIVIDUAL) WITH THAT OF OTHER TREATMENT MODALITIES.	2018
