1 1107 140 EFFECTS OF YOGA, STRENGTH TRAINING AND ADVICE ON BACK PAIN: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: AMONG THE WORKING POPULATION, NON-SPECIFIC LOW-BACK PAIN AND NECK PAIN ARE ONE OF THE MOST COMMON REASONS FOR SICKNESS ABSENTEEISM. THE AIM WAS TO EVALUATE THE EFFECTS OF AN EARLY INTERVENTION OF YOGA - COMPARED WITH STRENGTH TRAINING OR EVIDENCE-BASED ADVICE - ON SICKNESS ABSENTEEISM, SICKNESS PRESENTEEISM, BACK AND NECK PAIN AND DISABILITY AMONG A WORKING POPULATION. METHODS: A RANDOMIZED CONTROLLED TRIAL WAS CONDUCTED ON 159 PARTICIPANTS WITH PREDOMINANTLY (90%) CHRONIC BACK AND NECK PAIN. AFTER SCREENING, THE PARTICIPANTS WERE RANDOMIZED TO KUNDALINI YOGA, STRENGTH TRAINING OR EVIDENCE-BASED ADVICE. PRIMARY OUTCOME WAS SICKNESS ABSENTEEISM. SECONDARY OUTCOMES WERE SICKNESS PRESENTEEISM, BACK AND NECK PAIN AND DISABILITY. SELF-REPORTED QUESTIONNAIRES AND SMS TEXT MESSAGES WERE COMPLETED AT BASELINE, 6 WEEKS, 6 AND 12 MONTHS. RESULTS: THE RESULTS DID NOT INDICATE THAT KUNDALINI YOGA AND STRENGTH TRAINING HAD ANY STATISTICALLY SIGNIFICANT EFFECTS ON THE PRIMARY OUTCOME COMPARED WITH EVIDENCE-BASED ADVICE. AN INTERACTION EFFECT WAS FOUND BETWEEN ADHERENCE TO RECOMMENDATIONS AND SICKNESS ABSENTEEISM, INDICATING LARGER SIGNIFICANT EFFECTS AMONG THE ADHERERS TO KUNDALINI YOGA VERSUS EVIDENCE-BASED ADVICE: RR = 0.47 (CI 0.30; 0.74, P = 0.001), STRENGTH TRAINING VERSUS EVIDENCE-BASED ADVICE: RR = 0.60 (CI 0.38; 0.96, P = 0.032). SOME SIGNIFICANT DIFFERENCES WERE ALSO FOUND FOR THE SECONDARY OUTCOMES TO THE ADVANTAGE OF KUNDALINI YOGA AND STRENGTH TRAINING. CONCLUSIONS: GUIDED EXERCISE IN THE FORMS OF KUNDALINI YOGA OR STRENGTH TRAINING DOES NOT REDUCE SICKNESS ABSENTEEISM MORE THAN EVIDENCE-BASED ADVICE ALONE. HOWEVER, SECONDARY ANALYSES REVEAL THAT AMONG THOSE WHO PURSUE KUNDALINI YOGA OR STRENGTH TRAINING AT LEAST TWO TIMES A WEEK, A SIGNIFICANTLY REDUCTION IN SICKNESS ABSENTEEISM WAS FOUND. METHODS TO INCREASE ADHERENCE TO TREATMENT RECOMMENDATIONS SHOULD BE FURTHER DEVELOPED AND APPLIED IN EXERCISE INTERVENTIONS.

2  558  40 COST-EFFECTIVENESS OF YOGA FOR MANAGING MUSCULOSKELETAL CONDITIONS IN THE WORKPLACE. BACKGROUND: BACK PAIN AND MUSCULOSKELETAL CONDITIONS NEGATIVELY AFFECT THE HEALTH-RELATED QUALITY OF LIFE (HRQL) OF EMPLOYEES AND GENERATE SUBSTANTIAL COSTS TO EMPLOYERS. AIMS: TO ASSESS THE COST-EFFECTIVENESS OF YOGA FOR MANAGING MUSCULOSKELETAL CONDITIONS. METHODS: A RANDOMIZED CONTROLLED TRIAL EVALUATED AN 8-WEEK YOGA PROGRAMME, WITH A 6-MONTH FOLLOW-UP, FOR NATIONAL HEALTH SERVICE (NHS) EMPLOYEES. EFFECTIVENESS IN MANAGING MUSCULOSKELETAL CONDITIONS WAS ASSESSED USING REPEATED-MEASURES GENERALIZED LINEAR MODELLING FOR THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE (RDQ) AND THE KEELE START BACK SCREENING TOOL. COST-EFFECTIVENESS WAS DETERMINED USING AREA-UNDER-THE-CURVE LINEAR REGRESSION FOR ASSESSING HRQL FROM HEALTHCARE AND SOCIETAL PERSPECTIVES. THE INCREMENTAL COST PER QUALITY-ADJUSTED LIFE YEAR (QALY) WAS ALSO CALCULATED. SICKNESS ABSENCE WAS MEASURED USING ELECTRONIC STAFF RECORDS AT 6 MONTHS. RESULTS: THERE WERE 151 PARTICIPANTS. AT 6 MONTHS, MEAN DIFFERENCES BETWEEN GROUPS FAVOURING YOGA WERE OBSERVED FOR RDQ [-0.63 (95% CI, -1.78, 0.48)], KEELE START [-0.28 (95% CI, -0.97, 0.07)] AND HRQL (0.016 QALY GAIN). FROM A HEALTHCARE PERSPECTIVE, YOGA YIELDED AN INCREMENTAL COST-EFFECTIVENESS RATIO OF POUND2103 PER QALY. GIVEN A WILLINGNESS TO PAY FOR AN ADDITIONAL QALY OF POUND20 000, THE PROBABILITY OF YOGA BEING COST-EFFECTIVE WAS 95%. FROM A SOCIETAL PERSPECTIVE, YOGA WAS THE DOMINANT TREATMENT COMPARED WITH USUAL CARE. AT 6 MONTHS, ELECTRONIC STAFF RECORDS SHOWED THAT YOGA PARTICIPANTS MISSED A TOTAL OF 2 WORKING DAYS DUE TO MUSCULOSKELETAL CONDITIONS COMPARED WITH 43 DAYS FOR USUAL CARE PARTICIPANTS. CONCLUSIONS: YOGA FOR NHS EMPLOYEES MAY ENHANCE HRQL, REDUCE DISABILITY ASSOCIATED WITH BACK PAIN, LOWER SICKNESS ABSENCE DUE TO MUSCULOSKELETAL CONDITIONS AND IS LIKELY TO BE COST-EFFECTIVE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
3 2610  41 YOGA FOR REDUCING PERCEIVED STRESS AND BACK PAIN AT WORK. BACKGROUND: STRESS AND BACK PAIN ARE TWO KEY FACTORS LEADING TO SICKNESS ABSENCE AT WORK. RECENT RESEARCH INDICATES THAT YOGA CAN BE EFFECTIVE FOR REDUCING PERCEIVED STRESS, ALLEVIATING BACK PAIN, AND IMPROVING PSYCHOLOGICAL WELL-BEING. AIMS: TO DETERMINE THE EFFECTIVENESS OF A YOGA-BASED INTERVENTION FOR REDUCING PERCEIVED STRESS AND BACK PAIN AT WORK. METHODS: PARTICIPANTS WERE RECRUITED FROM A BRITISH LOCAL GOVERNMENT AUTHORITY AND RANDOMIZED INTO A YOGA GROUP WHO RECEIVED ONE 50 MIN DRU YOGA SESSION EACH WEEK FOR 8 WEEKS AND A 20 MIN DVD FOR HOME PRACTICE AND A CONTROL GROUP WHO RECEIVED NO INTERVENTION. BASELINE AND END-PROGRAMME MEASUREMENTS OF SELF-REPORTED STRESS, BACK PAIN AND PSYCHOLOGICAL WELL-BEING WERE ASSESSED WITH THE PERCEIVED STRESS SCALE, ROLAND MORRIS DISABILITY QUESTIONNAIRE AND THE POSITIVE AND NEGATIVE AFFECT SCALE. RESULTS: THERE WERE 37 PARTICIPANTS IN EACH GROUP. ANALYSIS OF VARIANCE AND MULTIPLE LINEAR REGRESSION SHOWED THAT IN COMPARISON TO THE CONTROL GROUP, THE YOGA GROUP REPORTED SIGNIFICANT REDUCTIONS IN PERCEIVED STRESS AND BACK PAIN, AND A SUBSTANTIAL IMPROVEMENT IN PSYCHOLOGICAL WELL-BEING. WHEN COMPARED WITH THE CONTROL GROUP AT THE END OF THE PROGRAMME, THE YOGA GROUP SCORES WERE SIGNIFICANTLY LOWER FOR PERCEIVED STRESS, BACK PAIN, SADNESS AND HOSTILITY, AND SUBSTANTIALLY HIGHER FOR FEELING SELF-ASSURED, ATTENTIVE AND SERENE. CONCLUSIONS: THE RESULTS INDICATE THAT A WORKPLACE YOGA INTERVENTION CAN REDUCE PERCEIVED STRESS AND BACK PAIN AND IMPROVE PSYCHOLOGICAL WELL-BEING. LARGER RANDOMIZED CONTROLLED TRIALS ARE NEEDED TO DETERMINE THE BROADER EFFICACY OF YOGA FOR IMPROVING WORKPLACE PRODUCTIVITY AND REDUCING SICKNESS ABSENCE.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
4  518  46 COMPARING ONCE- VERSUS TWICE-WEEKLY YOGA CLASSES FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY LOW INCOME MINORITIES: A RANDOMIZED DOSING TRIAL. BACKGROUND. PREVIOUS STUDIES HAVE DEMONSTRATED THAT ONCE-WEEKLY YOGA CLASSES ARE EFFECTIVE FOR CHRONIC LOW BACK PAIN (CLBP) IN WHITE ADULTS WITH HIGH SOCIOECONOMIC STATUS. THE COMPARATIVE EFFECTIVENESS OF TWICE-WEEKLY CLASSES AND GENERALIZABILITY TO RACIALLY DIVERSE LOW INCOME POPULATIONS ARE UNKNOWN. METHODS. WE CONDUCTED A 12-WEEK RANDOMIZED, PARALLEL-GROUP, DOSING TRIAL FOR 95 ADULTS RECRUITED FROM AN URBAN SAFETY-NET HOSPITAL AND FIVE COMMUNITY HEALTH CENTERS COMPARING ONCE-WEEKLY (N = 49) VERSUS TWICE-WEEKLY (N = 46) STANDARDIZED YOGA CLASSES SUPPLEMENTED BY HOME PRACTICE. PRIMARY OUTCOMES WERE CHANGE FROM BASELINE TO 12 WEEKS IN PAIN (11-POINT SCALE) AND BACK-RELATED FUNCTION (23-POINT MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE). RESULTS. 82% OF PARTICIPANTS WERE NONWHITE; 77% HAD ANNUAL HOUSEHOLD INCOMES <$40,000. THE SAMPLE'S BASELINE MEAN PAIN INTENSITY [6.9 (SD 1.6)] AND FUNCTION [13.7 (SD 5.0)] REFLECTED MODERATE TO SEVERE BACK PAIN AND IMPAIRMENT. PAIN AND BACK-RELATED FUNCTION IMPROVED WITHIN BOTH GROUPS (P < 0.001). HOWEVER, THERE WERE NO DIFFERENCES BETWEEN ONCE-WEEKLY AND TWICE-WEEKLY GROUPS FOR PAIN REDUCTION [-2.1 (95% CI -2.9, -1.3) VERSUS -2.4 (95% CI -3.1, -1.8), P = 0.62] OR BACK-RELATED FUNCTION [-5.1 (95% CI -7.0, -3.2) VERSUS -4.9 (95% CI -6.5, -3.3), P = 0.83]. CONCLUSIONS. TWELVE WEEKS OF ONCE-WEEKLY OR TWICE-WEEKLY YOGA CLASSES WERE SIMILARLY EFFECTIVE FOR PREDOMINANTLY LOW INCOME MINORITY ADULTS WITH MODERATE TO SEVERE CHRONIC LOW BACK PAIN.

5  540  56 COMPLIANCE EFFECTS IN A RANDOMISED CONTROLLED TRIAL OF YOGA FOR CHRONIC LOW BACK PAIN: A METHODOLOGICAL STUDY. STUDY DESIGN: METHODOLOGICAL STUDY NESTED WITHIN A MULTICENTRE RANDOMISED CONTROLLED TRIAL (RCT) OF YOGA PLUS USUAL GENERAL PRACTITIONER (GP) CARE VS USUAL GP CARE FOR CHRONIC LOW BACK PAIN. OBJECTIVE: TO EXPLORE THE TREATMENT EFFECTS OF NON-COMPLIANCE USING THREE APPROACHES IN AN RCT EVALUATING YOGA FOR LOW BACK PAIN. SUMMARY OF BACKGROUND DATA: A LARGE MULTICENTRE RCT USING INTENTION-TO-TREAT (ITT) ANALYSIS FOUND THAT PARTICIPANTS WITH CHRONIC LOW BACK PAIN WHO WERE OFFERED A 12-WEEK PROGRESSIVE PROGRAMME OF YOGA PLUS USUAL GP CARE HAD BETTER BACK FUNCTION THAN THOSE OFFERED USUAL GP CARE ALONE. HOWEVER, ITT ANALYSIS CAN UNDERESTIMATE THE EFFECT OF TREATMENT IN THOSE WHO COMPLY WITH TREATMENT. AS SUCH, THE DATA WERE ANALYSED USING OTHER APPROACHES TO ASSESS THE PROBLEM OF NON-COMPLIANCE. THE MAIN OUTCOME MEASURE WAS THE SELF-REPORTED ROLAND MORRIS DISABILITY QUESTIONNAIRE (RMDQ). METHODS: COMPLIER AVERAGE CAUSAL EFFECT (CACE) ANALYSIS, PER-PROTOCOL ANALYSIS AND ON-TREATMENT ANALYSIS WERE CONDUCTED ON THE DATA OF PARTICIPANTS WHO WERE FULLY COMPLIANT, PREDEFINED AS ATTENDANCE OF AT LEAST THREE OF THE FIRST SIX SESSIONS AND AT LEAST THREE OTHER SESSIONS. THE ANALYSIS WAS REPEATED FOR PARTICIPANTS WHO HAD ATTENDED AT LEAST ONE YOGA SESSION (I.E. ANY COMPLIANCE), WHICH INCLUDED PARTICIPANTS WHO WERE FULLY COMPLIANT. EACH APPROACH WAS DESCRIBED, INCLUDING STRENGTHS AND WEAKNESSES, AND THE RESULTS OF THE DIFFERENT APPROACHES WERE COMPARED WITH THOSE OF THE ITT ANALYSIS. RESULTS: FOR THE PARTICIPANTS WHO WERE FULLY COMPLIANT (N=93, 60%), A LARGER BENEFICIAL TREATMENT EFFECT WAS SEEN USING CACE ANALYSIS COMPARED WITH PER-PROTOCOL, ON-TREATMENT AND ITT ANALYSES AT 3 AND 12 MONTHS. THE DIFFERENCE IN MEAN CHANGE IN RMDQ SCORE BETWEEN RANDOMISED GROUPS WAS -3.30 [95% CONFIDENCE INTERVAL (CI) -4.90 TO -1.70, P<0.001] AT 3 MONTHS AND -2.23 (95% CI -3.93 TO -0.53, P=0.010) AT 12 MONTHS FOR CACE ANALYSIS, -3.12 (95% CI -4.26 TO -1.98, P<0.001) AT 3 MONTHS AND -2.11 (95% CI -3.33 TO -0.89, P=0.001) AT 12 MONTHS FOR PER-PROTOCOL ANALYSIS, AND -2.91 (95% CI -4.06 TO -1.76, P<0.001) AT 3 MONTHS AND -2.10 (95% CI -3.31 TO -0.89, P=0.001) AT 12 MONTHS FOR ON-TREATMENT ANALYSIS. FOR THE PARTICIPANTS WHO DEMONSTRATED ANY COMPLIANCE (N=133, 85%), THE RESULTS WERE GENERALLY CONSISTENT WITH THE FULLY COMPLIANT GROUP AT 3 MONTHS, BUT THE TREATMENT EFFECT WAS SMALLER. THE DIFFERENCE IN MEAN CHANGE IN RMDQ SCORE BETWEEN RANDOMISED GROUPS WAS -2.45 (95% CI -3.67 TO -1.24) FOR CACE ANALYSIS, -2.30 (95% CI -3.43 TO 1.17) FOR PER-PROTOCOL ANALYSIS AND -2.15 (95% CI -3.25 TO -1.06) FOR ON-TREATMENT ANALYSIS, WHICH WAS SLIGHTLY LESS THAN THAT FOR ITT ANALYSIS. IN CONTRAST, AT 12 MONTHS, PER-PROTOCOL AND ON-TREATMENT ANALYSES SHOWED A LARGER TREATMENT EFFECT COMPARED WITH CACE AND ITT ANALYSES: PER PROTOCOL ANALYSIS -1.86 (95% CI -3.02 TO -0.71), ON-TREATMENT ANALYSIS -1.99 (95% CI -3.13 TO -0.86) AND CACE ANALYSIS -1.67 (95% CI -2.95 TO -0.40). CONCLUSION: ITT ANALYSIS ESTIMATED A SLIGHTLY SMALLER TREATMENT EFFECT IN PARTICIPANTS WHO COMPLIED WITH TREATMENT. WHEN EXAMINING COMPLIANCE, CACE ANALYSIS IS MORE RIGOROUS THAN PER-PROTOCOL AND ON-TREATMENT ANALYSES. USING CACE ANALYSIS, THE TREATMENT EFFECT WAS LARGER IN PARTICIPANTS WHO COMPLIED WITH TREATMENT COMPARED WITH PARTICIPANTS WHO WERE ALLOCATED TO TREATMENT, AND THE DIFFERENCE BETWEEN ITT AND CACE ANALYSES FOR THE FULLY COMPLIANT GROUP AT 3 MONTHS WAS SMALL BUT CLINICALLY IMPORTANT. PER-PROTOCOL AND ON-TREATMENT ANALYSES MAY PRODUCE UNRELIABLE ESTIMATES WHEN THE EFFECT OF TREATMENT IS SMALL. INTERNATIONAL STANDARD RANDOMISED TRIAL NUMBER REGISTER: ISRCTN 81079604.	2014	

6 2560  49 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.

7  521  51 COMPARING YOGA, EXERCISE, AND A SELF-CARE BOOK FOR CHRONIC LOW BACK PAIN: A RANDOMIZED, CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN IS A COMMON PROBLEM THAT HAS ONLY MODESTLY EFFECTIVE TREATMENT OPTIONS. OBJECTIVE: TO DETERMINE WHETHER YOGA IS MORE EFFECTIVE THAN CONVENTIONAL THERAPEUTIC EXERCISE OR A SELF-CARE BOOK FOR PATIENTS WITH CHRONIC LOW BACK PAIN. DESIGN: RANDOMIZED, CONTROLLED TRIAL. SETTING: A NONPROFIT, INTEGRATED HEALTH CARE SYSTEM. PATIENTS: 101 ADULTS WITH CHRONIC LOW BACK PAIN. INTERVENTION: 12-WEEK SESSIONS OF YOGA OR CONVENTIONAL THERAPEUTIC EXERCISE CLASSES OR A SELF-CARE BOOK. MEASUREMENTS: PRIMARY OUTCOMES WERE BACK-RELATED FUNCTIONAL STATUS (MODIFIED 24-POINT ROLAND DISABILITY SCALE) AND "BOTHERSOMENESS" OF PAIN (11-POINT NUMERICAL SCALE). THE PRIMARY TIME POINT WAS 12 WEEKS. CLINICALLY SIGNIFICANT CHANGE WAS CONSIDERED TO BE 2.5 POINTS ON THE FUNCTIONAL STATUS SCALE AND 1.5 POINTS ON THE BOTHERSOMENESS SCALE. SECONDARY OUTCOMES WERE DAYS OF RESTRICTED ACTIVITY, GENERAL HEALTH STATUS, AND MEDICATION USE. RESULTS: AFTER ADJUSTMENT FOR BASELINE VALUES, BACK-RELATED FUNCTION IN THE YOGA GROUP WAS SUPERIOR TO THE BOOK AND EXERCISE GROUPS AT 12 WEEKS (YOGA VS. BOOK: MEAN DIFFERENCE, -3.4 [95% CI, -5.1 TO - 1.6] [P < 0.001]; YOGA VS. EXERCISE: MEAN DIFFERENCE, -1.8 [CI, -3.5 TO - 0.1] [P = 0.034]). NO SIGNIFICANT DIFFERENCES IN SYMPTOM BOTHERSOMENESS WERE FOUND BETWEEN ANY 2 GROUPS AT 12 WEEKS; AT 26 WEEKS, THE YOGA GROUP WAS SUPERIOR TO THE BOOK GROUP WITH RESPECT TO THIS MEASURE (MEAN DIFFERENCE, -2.2 [CI, -3.2 TO - 1.2]; P < 0.001). AT 26 WEEKS, BACK-RELATED FUNCTION IN THE YOGA GROUP WAS SUPERIOR TO THE BOOK GROUP (MEAN DIFFERENCE, -3.6 [CI, -5.4 TO - 1.8]; P < 0.001). LIMITATIONS: PARTICIPANTS IN THIS STUDY WERE FOLLOWED FOR ONLY 26 WEEKS AFTER RANDOMIZATION. ONLY 1 INSTRUCTOR DELIVERED EACH INTERVENTION. CONCLUSIONS: YOGA WAS MORE EFFECTIVE THAN A SELF-CARE BOOK FOR IMPROVING FUNCTION AND REDUCING CHRONIC LOW BACK PAIN, AND THE BENEFITS PERSISTED FOR AT LEAST SEVERAL MONTHS.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
8  193  47 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.

9  556  46 COST-EFFECTIVENESS OF EARLY INTERVENTIONS FOR NON-SPECIFIC LOW BACK PAIN: A RANDOMIZED CONTROLLED STUDY INVESTIGATING MEDICAL YOGA, EXERCISE THERAPY AND SELF-CARE ADVICE. OBJECTIVE: TO EVALUATE THE COST-EFFECTIVENESS OF MEDICAL YOGA AS AN EARLY INTERVENTION COMPARED WITH EVIDENCE-BASED EXERCISE THERAPY AND SELF-CARE ADVICE FOR NON-SPECIFIC LOW BACK PAIN. DESIGN: RANDOMIZED CONTROLLED TRIAL WITH A COST-EFFECTIVENESS ANALYSIS. SUBJECTS: A TOTAL OF 159 PARTICIPANTS RANDOMIZED INTO THE MEDICAL YOGA GROUP (N = 52), THE EXERCISE THERAPY GROUP (N = 52) AND THE SELF-CARE ADVICE GROUP (N = 55). METHODS: THE HEALTH OUTCOME MEASURE EQ-5D WAS APPLIED TO MEASURE QUALITY OF LIFE DATA COMBINED WITH COST DATA COLLECTED FROM TREATMENT GROUPS FROM BASELINE TO 12 MONTHS FOLLOW-UP. OUTCOME MEASURE WAS HEALTH-RELATED QUALITY OF LIFE (HRQL). INCREMENTAL COST PER QUALITY ADJUSTED LIFE YEAR (QALY) WAS ALSO CALCULATED. COST-EFFECTIVENESS ANALYSIS WAS CONDUCTED PRIMARILY FROM THE SOCIETAL AND EMPLOYER PERSPECTIVES. RESULTS: MEDICAL YOGA IS COST-EFFECTIVE COMPARED WITH SELF-CARE ADVICE IF AN EMPLOYER CONSIDERS THE SIGNIFICANT IMPROVEMENT IN THE HRQL OF AN EMPLOYEE WITH LOW BACK PAIN JUSTIFIES THE ADDITIONAL COST OF TREATMENT (I.E. IN THIS STUDY EUR 150). FROM A SOCIETAL PERSPECTIVE, MEDICAL YOGA IS A COST-EFFECTIVE TREATMENT COMPARED WITH EXERCISE THERAPY AND SELF-CARE ADVICE IF AN ADDITIONAL QALY IS WORTH EUR 11,500. SENSITIVITY ANALYSIS SUGGESTS THAT MEDICAL YOGA IS MORE COST-EFFECTIVE THAN ITS ALTERNATIVES. CONCLUSION: SIX WEEKS OF UNINTERRUPTED MEDICAL YOGA THERA-PY IS A COST-EFFECTIVE EARLY INTERVENTION FOR NON-SPECIFIC LOW BACK PAIN, WHEN TREATMENT RECOMMENDATIONS ARE ADHERED TO.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
10  132  41 A PRAGMATIC MULTICENTERED RANDOMIZED CONTROLLED TRIAL OF YOGA FOR CHRONIC LOW BACK PAIN: ECONOMIC EVALUATION. STUDY DESIGN: MULTICENTERED RANDOMIZED CONTROLLED TRIAL WITH QUALITY OF LIFE AND RESOURCE USE DATA COLLECTED. OBJECTIVE: THE OBJECTIVE OF THIS STUDY WAS TO EVALUATE THE COST-EFFECTIVENESS OF YOGA INTERVENTION PLUS USUAL CARE COMPARED WITH USUAL CARE ALONE FOR CHRONIC OR RECURRENT LOW BACK PAIN. SUMMARY OF BACKGROUND DATA: YOGA HAS BEEN SHOWN AS AN EFFECTIVE INTERVENTION FOR TREATING CHRONIC OR RECURRENT LOW BACK PAIN. HOWEVER, THERE IS LITTLE EVIDENCE ON ITS COST-EFFECTIVENESS. THE DATA ARE EXTRACTED FROM A PRAGMATIC, MULTICENTERED, RANDOMIZED CONTROLLED TRIAL THAT HAS BEEN CONDUCTED TO EVALUATE THE EFFECTIVENESS AND COST-EFFECTIVENESS OF A 12-WEEK PROGRESSIVE PROGRAM OF YOGA PLUS USUAL CARE IN PATIENTS WITH CHRONIC OR RECURRENT LOW BACK PAIN. METHODS: WITH THIS TRIAL DATA, A COST-EFFECTIVENESS ANALYSIS DURING THE TIME PERIOD OF 12 MONTHS FROM BOTH PERSPECTIVES OF THE UK NATIONAL HEALTH SERVICE AND THE SOCIETAL IS PRESENTED. MAIN OUTCOME MEASURE IS AN INCREMENTAL COST PER QUALITY-ADJUSTED LIFE-YEAR (QALY). RESULTS: FROM THE PERSPECTIVE OF THE U.K. NATIONAL HEALTH SERVICE, YOGA INTERVENTION YIELDS AN INCREMENTAL COST-EFFECTIVENESS RATIO OF POUND13,606 PER QALY. GIVEN A WILLINGNESS TO PAY FOR AN ADDITIONAL QALY OF POUND20,000, THE PROBABILITY OF YOGA INTERVENTION BEING COST-EFFECTIVE IS 72%. FROM THE PERSPECTIVE OF THE SOCIETY, YOGA INTERVENTION IS A DOMINANT TREATMENT COMPARED WITH USUAL CARE ALONE. THIS RESULT IS SURROUNDED BY FEWER UNCERTAINTIES-THE PROBABILITY OF YOGA BEING COST-EFFECTIVE REACHES 95% AT A WILLINGNESS TO PAY FOR AN ADDITIONAL QALY OF POUND20,000. SENSITIVE ANALYSES SUGGEST THE SAME RESULTS THAT YOGA INTERVENTION IS LIKELY TO BE COST-EFFECTIVE IN BOTH PERSPECTIVES. CONCLUSION: ON THE BASIS OF THIS TRIAL, 12 WEEKLY GROUP CLASSES OF SPECIALIZED YOGA ARE LIKELY TO BE A COST-EFFECTIVE INTERVENTION FOR TREATING PATIENTS WITH CHRONIC OR RECURRENT LOW BACK PAIN.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
11 2813  31 YOGA TO TREAT NONSPECIFIC LOW BACK PAIN. LOW BACK PAIN IS COMMON AND POSES A CHALLENGE FOR CLINICIANS TO FIND EFFECTIVE TREATMENT TO PREVENT IT FROM BECOMING CHRONIC. CHRONIC LOW BACK PAIN CAN HAVE A SIGNIFICANT IMPACT ON AN EMPLOYEE'S ABILITY TO REMAIN AN ACTIVE AND PRODUCTIVE MEMBER OF THE WORK FORCE DUE TO INCREASED ABSENTEEISM, DUTY RESTRICTIONS, OR PHYSICAL LIMITATIONS FROM PAIN. LOW BACK PAIN IS THE MOST COMMON CAUSE OF WORK-RELATED DISABILITY AMONG EMPLOYEES YOUNGER THAN 46 YEARS. ADVANCING TECHNOLOGY AND LESS INVASIVE SURGICAL PROCEDURES HAVE NOT IMPROVED OUTCOMES FOR EMPLOYEES WHO SUFFER FROM LOW BACK PAIN. MOST CONTINUE TO EXPERIENCE SOME PAIN AND DYSFUNCTION AFTER CONVENTIONAL TREATMENTS SUCH AS INJECTIONS AND SURGERY. AN ALTERNATIVE TREATMENT THAT COULD REDUCE NONSPECIFIC CHRONIC LOW BACK PAIN WOULD BENEFIT BOTH EMPLOYEES AND EMPLOYERS. EXERCISING AND REMAINING ACTIVE ARE PART OF MOST GUIDELINES' ROUTINE CARE RECOMMENDATIONS BUT ARE NOT WELL DEFINED.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
12 1054  43 EFFECTS OF YOGA ON CHRONIC NECK PAIN: A SYSTEMATIC REVIEW AND META-ANALYSIS. OBJECTIVE: THE AIM OF THIS REVIEW WAS TO SYSTEMATICALLY ASSESS AND META-ANALYZE THE EFFECTIVENESS OF YOGA IN RELIEVING CHRONIC NECK PAIN. METHODS: PUBMED/MEDLINE, THE COCHRANE LIBRARY, SCOPUS, AND INDMED WERE SCREENED THROUGH JANUARY 2017 FOR RANDOMIZED CONTROLLED TRIALS ASSESSING NECK PAIN INTENSITY AND/OR NECK PAIN-RELATED DISABILITY IN CHRONIC NECK PAIN PATIENTS. SECONDARY OUTCOME MEASURES INCLUDED QUALITY OF LIFE, MOOD, AND SAFETY. RISK OF BIAS WAS ASSESSED USING THE COCHRANE TOOL. RESULTS: THREE STUDIES ON 188 PATIENTS WITH CHRONIC NON-SPECIFIC NECK PAIN COMPARING YOGA TO USUAL CARE WERE INCLUDED. TWO STUDIES HAD OVERALL LOW RISK OF BIAS; AND ONE HAD HIGH OR UNCLEAR RISK OF BIAS FOR SEVERAL DOMAINS. EVIDENCE FOR SHORT-TERM EFFECTS WAS FOUND FOR NECK PAIN INTENSITY (STANDARDIZED MEAN DIFFERENCE (SMD) = -1.28; 95% CONFIDENCE INTERVAL (CI) = -1.18, -0.75; P < 0.001), NECK PAIN-RELATED DISABILITY (SMD = -0.97; 95% CI = -1.44, -0.50; P < 0.001), QUALITY OF LIFE (SMD = 0.57; 95% CI = 0.17, 0.197; P = 0.005), AND MOOD (SMD = -1.02; 95% CI = -1.38, -0.65; P < 0.001). EFFECTS WERE ROBUST AGAINST POTENTIAL METHODOLOGICAL BIAS AND DID NOT DIFFER BETWEEN DIFFERENT INTERVENTION SUBGROUPS. IN THE TWO STUDIES THAT INCLUDED SAFETY DATA, NO SERIOUS ADVERSE EVENTS OCCURRED. CONCLUSION: YOGA HAS SHORT-TERM EFFECTS ON CHRONIC NECK PAIN, ITS RELATED DISABILITY, QUALITY OF LIFE, AND MOOD SUGGESTING THAT YOGA MIGHT BE A GOOD TREATMENT OPTION.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
13  557  44 COST-EFFECTIVENESS OF YOGA FOR CHRONIC LOW BACK PAIN IN VETERANS. BACKGROUND: YOGA INTERVENTIONS CAN IMPROVE FUNCTION AND REDUCE PAIN IN PERSONS WITH CHRONIC LOW BACK PAIN (CLBP). OBJECTIVE: USING DATA FROM A RECENT TRIAL OF YOGA FOR MILITARY VETERANS WITH CLBP, WE ANALYZED THE INCREMENTAL COST-EFFECTIVENESS OF YOGA COMPARED WITH USUAL CARE. METHODS: PARTICIPANTS (N=150) WERE RANDOMIZED TO EITHER 2X WEEKLY, 60-MINUTE YOGA SESSIONS FOR 12 WEEKS, OR TO DELAYED TREATMENT (DT). OUTCOMES WERE MEASURED AT 12 WEEKS, AND 6 MONTHS. QUALITY-ADJUSTED LIFE YEARS (QALYS) WERE MEASURED USING THE EQ-5D SCALE. A 30% IMPROVEMENT ON THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE (PRIMARY OUTCOME) SERVED AS AN ADDITIONAL EFFECTIVENESS MEASURE. INTERVENTION COSTS INCLUDING PERSONNEL, MATERIALS, AND TRANSPORTATION WERE TRACKED DURING THE STUDY. HEALTH CARE COSTS WERE OBTAINED FROM PATIENT MEDICAL RECORDS. HEALTH CARE ORGANIZATION AND SOCIETAL PERSPECTIVES WERE EXAMINED WITH A 12-MONTH HORIZON. RESULTS: INCREMENTAL QALYS GAINED BY THE YOGA GROUP OVER 12 MONTHS WERE 0.043. INTERVENTION COSTS TO DELIVER YOGA WERE $307/PARTICIPANT. NEGLIGIBLE DIFFERENCES IN HEALTH CARE COSTS WERE FOUND BETWEEN GROUPS. FROM THE HEALTH CARE ORGANIZATION PERSPECTIVE, THE INCREMENTAL COST-EFFECTIVENESS RATIO TO PROVIDE YOGA WAS $4488/QALY. FROM THE SOCIETAL PERSPECTIVE, YOGA WAS "DOMINANT" PROVIDING BOTH HEALTH BENEFIT AND COST SAVINGS. PROBABILISTIC SENSITIVITY ANALYSIS INDICATES AN 89% CHANCE OF YOGA BEING COST-EFFECTIVE AT A WILLINGNESS-TO-PAY OF $50,000. A SCENARIO COMPARING THE COSTS OF YOGA AND PHYSICAL THERAPY SUGGEST THAT YOGA MAY PRODUCE SIMILAR RESULTS AT A MUCH LOWER COST.

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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
15 1959  26 SELF-MANAGEMENT SUPPORT WITH YOGA ON PSYCHOLOGICAL HEALTH AND QUALITY OF LIFE FOR BREAST CANCER SURVIVORS. THE PURPOSE OF THIS STUDY WAS TO IDENTIFY WHETHER THE IMPROVEMENT OF SELF-MANAGEMENT SUPPORT (SMS) COMBINED WITH YOGA CAN IMPROVE ANXIETY, DEPRESSION, STRESS, AND QUALITY OF LIFE IN FEMALE BREAST CANCER SURVIVORS. THE SMS COMBINED WITH YOGA GROUP AND CONTROL GROUP (YOGA ONLY) WERE COMPRISED OF 21 AND 20 PARTICIPANTS, RESPECTIVELY. THE SMS WITH YOGA AND YOGA PROGRAMS WERE PROVIDED TO EACH GROUP FOR 8 WEEKS. DATA OBTAINED FROM SELF-REPORT QUESTIONNAIRES INCLUDED DETAILS OF ANXIETY, DEPRESSION, STRESS, AND QUALITY OF LIFE. THE LEVELS OF ANXIETY, DEPRESSION, AND STRESS SIGNIFICANTLY DECREASED IN BOTH THE SMS WITH YOGA AND CONTROL GROUPS (P &LT; 0.05). MOREOVER, THE QUALITY OF LIFE IMPROVED SIGNIFICANTLY IN THE SMS WITH YOGA GROUP (P &LT; 0.001). AMONG THE FIVE QUALITY-OF-LIFE DOMAINS (PHYSICAL, SOCIAL/FAMILY, EMOTIONAL AND FUNCTIONAL WELL-BEING, AND BREAST CANCER SUBSCALE), SOCIAL/FAMILY WELL-BEING IN THE SMS WITH YOGA GROUP WAS SIGNIFICANTLY HIGHER THAN THAT IN THE YOGA-ONLY GROUP (P = 0.011). CONCLUSIONS: THE RESULTS SHOW THAT YOGA IS A BENEFICIAL ACTIVITY FOR THE PSYCHOLOGICAL HEALTH OF BREAST CANCER SURVIVORS. OUR FINDINGS SUGGEST THAT SMS STRATEGIES CAN IMPROVE QUALITY OF LIFE.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
16 2831  43 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.

17 2824  44 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.

18 2852  46 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.

19 2330  32 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
20  461  53 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
