1 1494 140 INTERRATER RELIABILITY OF AN OBSERVATIONAL RATING SCALE AND VIDEO ANALYSIS OF YOGA POSES. CONTEXT: YOGA IS INCREASINGLY POPULAR, NOT ONLY AS A FORM OF RECREATIONAL EXERCISE BUT ALSO AS A PHYSICIAN-RECOMMENDED INTERVENTION FOR HEALTH CONDITIONS. WHILE SERIOUS ADVERSE EFFECTS ACCOMPANYING YOGA PRACTICE ARE RARE, POSES THAT INVOLVE UPPER-EXTREMITY WEIGHT-BEARING HAVE A HIGH RISK OF DISCOMFORT. TO BETTER UNDERSTAND FACTORS CONTRIBUTING TO ADVERSE EFFECTS, THERE IS A CRITICAL NEED FOR ROBUST INSTRUMENTS THAT OBJECTIVELY EVALUATE POSE PERFORMANCE. THE PURPOSE OF THIS STUDY WAS TO ASSESS THE INTERRATER RELIABILITY OF AN OBSERVATIONAL SCALE DEVELOPED TO ASSESS THE ALIGNMENT OF 3 YOGA POSES. DESIGN: CROSS-SECTIONAL EXPERIMENTAL STUDY. METHODS: THIRTY-EIGHT INDIVIDUALS WERE GIVEN STANDARDIZED INSTRUCTIONS AND PERFORMED 3 POSES (DOWNWARD DOG, PLANK, AND SIDE PLANK). LATERAL VIDEOS WERE RATED BY 2 RATERS. A RATING SCALE EVALUATING THE ALIGNMENT OF 7 REGIONS WAS DEVELOPED BY THE STUDY TEAM WITH INPUT FROM YOGA TEACHERS. DESCRIPTIVE STATISTICS WERE USED TO SUMMARIZE THE PERCENTAGE OF SUBJECTS SHOWING IDEAL ALIGNMENT AND DEVIATIONS. INTERRATER RELIABILITY WAS QUANTIFIED USING COHEN KAPPA COEFFICIENT (KAPPA). RESULTS: IN DOWNWARD DOG, THE PREVALENCE OF IDEAL ALIGNMENT WAS 20%, 28%, AND 37%, AT THE NECK, SHOULDER, AND BACK, RESPECTIVELY; KAPPA RANGED FROM .44 TO .69. IN PLANK, THE PREVALENCE OF IDEAL ALIGNMENT WAS 31%, 45%, AND 54% AT THE NECK, SHOULDER, AND BACK, RESPECTIVELY; KAPPA RANGED FROM .47 TO .95. IN SIDE PLANK, THE PREVALENCE OF IDEAL ALIGNMENT WAS 16, 41%, AND 24%, AT THE NECK, SHOULDER, AND BACK, RESPECTIVELY; KAPPA RANGED FROM .20 TO .84. CONCLUSION: THE OBSERVATIONAL SCALE FOUND A HIGH PREVALENCE OF DEVIATIONS, AND DEMONSTRATED FAIR TO SUBSTANTIAL INTERRATER AGREEMENT.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
2 1488  24 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.

3 2768  34 YOGA REDUCES INFLAMMATORY SIGNALING IN FATIGUED BREAST CANCER SURVIVORS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: YOGA IS A POPULAR MIND-BODY THERAPY THAT HAS DEMONSTRATED BENEFICIAL EFFECTS ON PSYCHOLOGICAL, BEHAVIORAL, AND FUNCTIONAL OUTCOMES. HOWEVER, FEW STUDIES HAVE INVESTIGATED EFFECTS ON INFLAMMATORY PROCESSES. THIS STUDY TESTED THE HYPOTHESIS THAT AN IYENGAR YOGA INTERVENTION SPECIFICALLY DESIGNED FOR FATIGUED BREAST CANCER SURVIVORS WOULD LEAD TO DECREASES IN INFLAMMATION-RELATED GENE EXPRESSION AND CIRCULATING MARKERS OF PROINFLAMMATORY CYTOKINE ACTIVITY. METHODS: BREAST CANCER SURVIVORS WITH PERSISTENT CANCER-RELATED FATIGUE WERE RANDOMIZED TO A 12-WEEK IYENGAR YOGA INTERVENTION (N=16) OR A 12-WEEK HEALTH EDUCATION CONTROL CONDITION (N=15). BLOOD SAMPLES WERE COLLECTED AT BASELINE, POST-INTERVENTION, AND AT A 3-MONTH FOLLOW-UP FOR GENOME-WIDE TRANSCRIPTIONAL PROFILING AND BIOINFORMATIC ANALYSES. PLASMA INFLAMMATORY MARKERS AND SALIVARY CORTISOL WERE ALSO ASSESSED. RESULTS: IN PROMOTER-BASED BIOINFORMATICS ANALYSES, THE YOGA GROUP SHOWED REDUCED ACTIVITY OF THE PRO-INFLAMMATORY TRANSCRIPTION FACTOR NUCLEAR FACTOR KAPPA B (NF-KAPPAB), INCREASED ACTIVITY OF THE ANTI-INFLAMMATORY GLUCOCORTICOID RECEPTOR, AND REDUCED ACTIVITY OF CAMP RESPONSE ELEMENT-BINDING PROTEIN (CREB) FAMILY TRANSCRIPTION FACTORS RELATIVE TO CONTROLS (ALL PS<.05). THERE WAS ALSO A SIGNIFICANT INTERVENTION EFFECT ON THE SOLUBLE TUMOR NECROSIS FACTOR RECEPTOR TYPE II (STNF-RII), A MARKER OF TNF ACTIVITY; PLASMA LEVELS OF STNF-RII REMAINED STABLE IN THE YOGA GROUP, WHEREAS LEVELS OF THIS MARKER INCREASED IN THE HEALTH EDUCATION GROUP (P=.028). A SIMILAR, NON-SIGNIFICANT TREND WAS OBSERVED FOR THE INTERLEUKIN 1 RECEPTOR ANTAGONIST (P=.16). NO SIGNIFICANT CHANGES IN C REACTIVE PROTEIN (CRP), INTERLEUKIN 6 (IL-6), OR DIURNAL CORTISOL MEASURES WERE OBSERVED. CONCLUSIONS: A 12-WEEK RESTORATIVE IYENGAR YOGA INTERVENTION REDUCED INFLAMMATION-RELATED GENE EXPRESSION IN BREAST CANCER SURVIVORS WITH PERSISTENT FATIGUE. THESE FINDINGS SUGGEST THAT A TARGETED YOGA PROGRAM MAY HAVE BENEFICIAL EFFECTS ON INFLAMMATORY ACTIVITY IN THIS PATIENT POPULATION, WITH POTENTIAL RELEVANCE FOR BEHAVIORAL AND PHYSICAL HEALTH.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
4  518  30 COMPARING ONCE- VERSUS TWICE-WEEKLY YOGA CLASSES FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY LOW INCOME MINORITIES: A RANDOMIZED DOSING TRIAL. BACKGROUND. PREVIOUS STUDIES HAVE DEMONSTRATED THAT ONCE-WEEKLY YOGA CLASSES ARE EFFECTIVE FOR CHRONIC LOW BACK PAIN (CLBP) IN WHITE ADULTS WITH HIGH SOCIOECONOMIC STATUS. THE COMPARATIVE EFFECTIVENESS OF TWICE-WEEKLY CLASSES AND GENERALIZABILITY TO RACIALLY DIVERSE LOW INCOME POPULATIONS ARE UNKNOWN. METHODS. WE CONDUCTED A 12-WEEK RANDOMIZED, PARALLEL-GROUP, DOSING TRIAL FOR 95 ADULTS RECRUITED FROM AN URBAN SAFETY-NET HOSPITAL AND FIVE COMMUNITY HEALTH CENTERS COMPARING ONCE-WEEKLY (N = 49) VERSUS TWICE-WEEKLY (N = 46) STANDARDIZED YOGA CLASSES SUPPLEMENTED BY HOME PRACTICE. PRIMARY OUTCOMES WERE CHANGE FROM BASELINE TO 12 WEEKS IN PAIN (11-POINT SCALE) AND BACK-RELATED FUNCTION (23-POINT MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE). RESULTS. 82% OF PARTICIPANTS WERE NONWHITE; 77% HAD ANNUAL HOUSEHOLD INCOMES <$40,000. THE SAMPLE'S BASELINE MEAN PAIN INTENSITY [6.9 (SD 1.6)] AND FUNCTION [13.7 (SD 5.0)] REFLECTED MODERATE TO SEVERE BACK PAIN AND IMPAIRMENT. PAIN AND BACK-RELATED FUNCTION IMPROVED WITHIN BOTH GROUPS (P < 0.001). HOWEVER, THERE WERE NO DIFFERENCES BETWEEN ONCE-WEEKLY AND TWICE-WEEKLY GROUPS FOR PAIN REDUCTION [-2.1 (95% CI -2.9, -1.3) VERSUS -2.4 (95% CI -3.1, -1.8), P = 0.62] OR BACK-RELATED FUNCTION [-5.1 (95% CI -7.0, -3.2) VERSUS -4.9 (95% CI -6.5, -3.3), P = 0.83]. CONCLUSIONS. TWELVE WEEKS OF ONCE-WEEKLY OR TWICE-WEEKLY YOGA CLASSES WERE SIMILARLY EFFECTIVE FOR PREDOMINANTLY LOW INCOME MINORITY ADULTS WITH MODERATE TO SEVERE CHRONIC LOW BACK PAIN. THIS TRIAL IS REGISTERED WITH CLINICALTRIALS.GOV NCT01761617.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
5 2558  33 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                       
6  521  30 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
7 1787  33 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	

8  193  28 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 2852  32 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.

10 2836  34 YOGA'S IMPACT ON INFLAMMATION, MOOD, AND FATIGUE IN BREAST CANCER SURVIVORS: A RANDOMIZED CONTROLLED TRIAL. PURPOSE: TO EVALUATE YOGA'S IMPACT ON INFLAMMATION, MOOD, AND FATIGUE. PATIENTS AND METHODS: A RANDOMIZED CONTROLLED 3-MONTH TRIAL WAS CONDUCTED WITH TWO POST-TREATMENT ASSESSMENTS OF 200 BREAST CANCER SURVIVORS ASSIGNED TO EITHER 12 WEEKS OF 90-MINUTE TWICE PER WEEK HATHA YOGA CLASSES OR A WAIT-LIST CONTROL. THE MAIN OUTCOME MEASURES WERE LIPOPOLYSACCHARIDE-STIMULATED PRODUCTION OF PROINFLAMMATORY CYTOKINES INTERLEUKIN-6 (IL-6), TUMOR NECROSIS FACTOR ALPHA (TNF-ALPHA), AND INTERLEUKIN-1BETA (IL-1BETA), AND SCORES ON THE MULTIDIMENSIONAL FATIGUE SYMPTOM INVENTORY-SHORT FORM (MFSI-SF), THE VITALITY SCALE FROM THE MEDICAL OUTCOMES STUDY 36-ITEM SHORT FORM (SF-36), AND THE CENTER FOR EPIDEMIOLOGICAL STUDIES-DEPRESSION (CES-D) SCALE. RESULTS: IMMEDIATELY POST-TREATMENT, FATIGUE WAS NOT LOWER (P > .05) BUT VITALITY WAS HIGHER (P = .01) IN THE YOGA GROUP COMPARED WITH THE CONTROL GROUP. AT 3 MONTHS POST-TREATMENT, FATIGUE WAS LOWER IN THE YOGA GROUP (P = .002), VITALITY WAS HIGHER (P = .01), AND IL-6 (P = .027), TNF-ALPHA (P = .027), AND IL-1BETA (P = .037) WERE LOWER FOR YOGA PARTICIPANTS COMPARED WITH THE CONTROL GROUP. GROUPS DID NOT DIFFER ON DEPRESSION AT EITHER TIME (P > .2). PLANNED SECONDARY ANALYSES SHOWED THAT THE FREQUENCY OF YOGA PRACTICE HAD STRONGER ASSOCIATIONS WITH FATIGUE AT BOTH POST-TREATMENT VISITS (P = .019; P < .001), AS WELL AS VITALITY (P = .016; P = .0045), BUT NOT DEPRESSION (P > .05) THAN SIMPLE GROUP ASSIGNMENT; MORE FREQUENT PRACTICE PRODUCED LARGER CHANGES. AT 3 MONTHS POST-TREATMENT, INCREASING YOGA PRACTICE ALSO LED TO A DECREASE IN IL-6 (P = .01) AND IL-1BETA (P = .03) PRODUCTION BUT NOT IN TNF-ALPHA PRODUCTION (P > .05). CONCLUSION: CHRONIC INFLAMMATION MAY FUEL DECLINES IN PHYSICAL FUNCTION LEADING TO FRAILTY AND DISABILITY. IF YOGA DAMPENS OR LIMITS BOTH FATIGUE AND INFLAMMATION, THEN REGULAR PRACTICE COULD HAVE SUBSTANTIAL HEALTH BENEFITS.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
11  465  33 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
12 2560  34 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.

13 1699  30 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	
                                                                                                                                                                                                                                                                                                                                                                                          
14  638  29 DO PHYSICAL THERAPY AND YOGA IMPROVE PAIN AND DISABILITY THROUGH PSYCHOLOGICAL MECHANISMS? A CAUSAL MEDIATION ANALYSIS OF ADULTS WITH CHRONIC LOW BACK PAIN. OBJECTIVE: TO INVESTIGATE WHETHER INDIRECT EFFECTS VIA PSYCHOLOGICAL MECHANISMS EXPLAIN THE EFFECTS OF PHYSICAL THERAPY (PT) OR YOGA, VERSUS EDUCATION, ON BACK-RELATED OUTCOMES. DESIGN: MEDIATION ANALYSES USING DATA FROM A RANDOMIZED CONTROLLED TRIAL OF PT, YOGA, AND EDUCATION INTERVENTIONS FOR CHRONIC LOW BACK PAIN. METHODS: PRIMARY OUTCOMES WERE CHANGES IN BACK-RELATED PAIN ON THE 11-POINT NUMERICAL RATING SCALE AND DISABILITY ON THE MODIFIED 23-POINT ROLAND MORRIS DISABILITY QUESTIONNAIRE, MEASURED AT 52-WEEKS POST-RANDOMIZATION. HYPOTHESIZED MEDIATORS WERE 12-WEEK CHANGES IN PAIN SELF-EFFICACY, FEAR AVOIDANCE BELIEFS, DEPRESSION, ANXIETY, PERCEIVED STRESS, AND SLEEP QUALITY. WE USED CAUSAL MEDIATION ANALYSIS TO ESTIMATE THE TOTAL EFFECT, DIRECT EFFECT, INDIRECT EFFECT, AND PROPORTION MEDIATED. RESULTS: WE ANALYZED DATA FROM 230 ADULTS (MEAN AGE = 46.2 YEARS, 69.6% FEMALE, 79.6% NON-WHITE). IN THE PT VERSUS EDUCATION MODEL, WHEN THE MEDIATOR WAS PERCEIVED STRESS, THE TOTAL EFFECT ON DISABILITY WAS 2.6 POINTS (95% CI: 0.3, 4.9) AND DECOMPOSED INTO A DIRECT EFFECT OF 1.7 POINTS (95% CI: -0.4, 3.8) AND AN INDIRECT EFFECT 0.9 POINTS (95% CI: 0.1, 2.0; PROPORTION MEDIATED 34%). NO OTHER PSYCHOLOGICAL CONSTRUCT WAS A SIGNIFICANT MEDIATOR. CONCLUSION: IMPROVEMENTS IN PERCEIVED STRESS MEDIATED IMPROVEMENTS IN DISABILITY AFTER PT TREATMENT COMPARED TO EDUCATION. OTHER PSYCHOLOGICAL OUTCOMES DID NOT MEDIATE THE EFFECT OF YOGA OR PT ON PAIN OR DISABILITY OUTCOMES COMPARED TO EDUCATION. J ORTHOP SPORTS PHYS THER, EPUB 18 MAY 2022.

15  162  33 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	
                                                                                                                                                                                                                                                                                                                                                              
16 2604  34 YOGA FOR PERSISTENT FATIGUE IN BREAST CANCER SURVIVORS: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CANCER-RELATED FATIGUE AFFLICTS UP TO 33% OF BREAST CANCER SURVIVORS, YET THERE ARE NO EMPIRICALLY VALIDATED TREATMENTS FOR THIS SYMPTOM. METHODS: THE AUTHORS CONDUCTED A 2-GROUP RANDOMIZED CONTROLLED TRIAL TO DETERMINE THE FEASIBILITY AND EFFICACY OF AN IYENGAR YOGA INTERVENTION FOR BREAST CANCER SURVIVORS WITH PERSISTENT POST-TREATMENT FATIGUE. PARTICIPANTS WERE BREAST CANCER SURVIVORS WHO HAD COMPLETED CANCER TREATMENTS (OTHER THAN ENDOCRINE THERAPY) AT LEAST 6 MONTHS BEFORE ENROLLMENT, REPORTED SIGNIFICANT CANCER-RELATED FATIGUE, AND HAD NO OTHER MEDICAL CONDITIONS THAT WOULD ACCOUNT FOR FATIGUE SYMPTOMS OR INTERFERE WITH YOGA PRACTICE. BLOCK RANDOMIZATION WAS USED TO ASSIGN PARTICIPANTS TO A 12-WEEK, IYENGAR-BASED YOGA INTERVENTION OR TO 12 WEEKS OF HEALTH EDUCATION (CONTROL). THE PRIMARY OUTCOME WAS CHANGE IN FATIGUE MEASURED AT BASELINE, IMMEDIATELY POST-TREATMENT, AND 3 MONTHS AFTER TREATMENT COMPLETION. ADDITIONAL OUTCOMES INCLUDED CHANGES IN VIGOR, DEPRESSIVE SYMPTOMS, SLEEP, PERCEIVED STRESS, AND PHYSICAL PERFORMANCE. INTENT-TO-TREAT ANALYSES WERE CONDUCTED WITH ALL RANDOMIZED PARTICIPANTS USING LINEAR MIXED MODELS. RESULTS: THIRTY-ONE WOMEN WERE RANDOMLY ASSIGNED TO YOGA (N = 16) OR HEALTH EDUCATION (N = 15). FATIGUE SEVERITY DECLINED SIGNIFICANTLY FROM BASELINE TO POST-TREATMENT AND OVER A 3-MONTH FOLLOW-UP IN THE YOGA GROUP RELATIVE TO CONTROLS (P = .032). IN ADDITION, THE YOGA GROUP HAD SIGNIFICANT INCREASES IN VIGOR RELATIVE TO CONTROLS (P = .011). BOTH GROUPS HAD POSITIVE CHANGES IN DEPRESSIVE SYMPTOMS AND PERCEIVED STRESS (P < .05). NO SIGNIFICANT CHANGES IN SLEEP OR PHYSICAL PERFORMANCE WERE OBSERVED. CONCLUSIONS: A TARGETED YOGA INTERVENTION LED TO SIGNIFICANT IMPROVEMENTS IN FATIGUE AND VIGOR AMONG BREAST CANCER SURVIVORS WITH PERSISTENT FATIGUE SYMPTOMS.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
17 1462  31 INFLUENCE OF YOGA ON POSTOPERATIVE OUTCOMES AND WOUND HEALING IN EARLY OPERABLE BREAST CANCER PATIENTS UNDERGOING SURGERY. CONTEXT: PRE- AND POSTOPERATIVE DISTRESS IN BREAST CANCER PATIENTS CAN CAUSE COMPLICATIONS AND DELAY RECOVERY FROM SURGERY. OBJECTIVE: THE AIM OF OUR STUDY WAS TO EVALUATE THE EFFECTS OF YOGA INTERVENTION ON POSTOPERATIVE OUTCOMES AND WOUND HEALING IN EARLY OPERABLE BREAST CANCER PATIENTS UNDERGOING SURGERY. METHODS: NINETY-EIGHT RECENTLY DIAGNOSED STAGE II AND III BREAST CANCER PATIENTS WERE RECRUITED IN A RANDOMIZED CONTROLLED TRIAL COMPARING THE EFFECTS OF A YOGA PROGRAM WITH SUPPORTIVE THERAPY AND EXERCISE REHABILITATION ON POSTOPERATIVE OUTCOMES AND WOUND HEALING FOLLOWING SURGERY. SUBJECTS WERE ASSESSED AT THE BASELINE PRIOR TO SURGERY AND FOUR WEEKS LATER. SOCIODEMOGRAPHIC, CLINICAL AND INVESTIGATIVE NOTES WERE ASCERTAINED IN THE BEGINNING OF THE STUDY. BLOOD SAMPLES WERE COLLECTED FOR ESTIMATION OF PLASMA CYTOKINES-SOLUBLE INTERLEUKIN (IL)-2 RECEPTOR (IL-2R), TUMOR NECROSIS FACTOR (TNF)-ALPHA AND INTERFERON (IFN)-GAMMA. POSTOPERATIVE OUTCOMES SUCH AS THE DURATION OF HOSPITAL STAY AND DRAIN RETENTION, TIME OF SUTURE REMOVAL AND POSTOPERATIVE COMPLICATIONS WERE ASCERTAINED. WE USED INDEPENDENT SAMPLES T TEST AND NONPARAMETRIC MANN WHITNEY U TESTS TO COMPARE GROUPS FOR POSTOPERATIVE OUTCOMES AND PLASMA CYTOKINES. REGRESSION ANALYSIS WAS DONE TO DETERMINE PREDICTORS FOR POSTOPERATIVE OUTCOMES. RESULTS: SIXTY-NINE PATIENTS CONTRIBUTED DATA TO THE CURRENT ANALYSIS (YOGA: N = 33, CONTROL: N = 36). THE RESULTS SUGGEST A SIGNIFICANT DECREASE IN THE DURATION OF HOSPITAL STAY (P = 0.003), DAYS OF DRAIN RETENTION (P = 0.001) AND DAYS FOR SUTURE REMOVAL (P = 0.03) IN THE YOGA GROUP AS COMPARED TO THE CONTROLS. THERE WAS ALSO A SIGNIFICANT DECREASE IN PLASMA TNF ALPHA LEVELS FOLLOWING SURGERY IN THE YOGA GROUP (P < 0.001), AS COMPARED TO THE CONTROLS. REGRESSION ANALYSIS ON POSTOPERATIVE OUTCOMES SHOWED THAT THE YOGA INTERVENTION AFFECTED THE DURATION OF DRAIN RETENTION AND HOSPITAL STAY AS WELL AS TNF ALPHA LEVELS. CONCLUSION: THE RESULTS SUGGEST POSSIBLE BENEFITS OF YOGA IN REDUCING POSTOPERATIVE COMPLICATIONS IN BREAST CANCER PATIENTS.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
18  920  30 EFFECTIVENESS OF YOGA AND EDUCATIONAL INTERVENTION ON DISABILITY, ANXIETY, DEPRESSION, AND PAIN IN PEOPLE WITH CLBP: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: THE CURRENT STUDY INVESTIGATES THE EFFECTS OF AN 8-WEEK YOGA PROGRAM WITH EDUCATIONAL INTERVENTION COMPARED WITH AN INFORMATIONAL PAMPHLET ON DISABILITY, ANXIETY, DEPRESSION, AND PAIN, IN PEOPLE AFFECTED BY CHRONIC LOW BACK PAIN (CLBP). METHODS: THIRTY INDIVIDUALS (AGE 34.2+/-4.52YRS) WITH CLBP WERE RANDOMLY ASSIGNED INTO A YOGA GROUP (YG, N=15) AND A PAMPHLET GROUP (PG, N=15). THE YG PARTICIPATED IN AN 8-WEEK (2 DAYS PER WEEK) YOGA PROGRAM WHICH INCLUDED EDUCATION ON SPINE ANATOMY/BIOMECHANICS AND THE MANAGEMENT OF CLBP. MAIN OUTCOME MEASURES: MONITORING RESPONSE TO INTERVENTION, THE OSWESTRY LOW BACK PAIN DISABILITY QUESTIONNAIRE (ODI-I), ZUNG SELF-RATING DEPRESSION SCALE (SDS), ZUNG SELF-RATING ANXIETY SCALE (SAS) AND NUMERIC RATING SCALE FOR PAIN (NRS 0-10) WERE USED TO COLLECT DATA. RESULTS: AFTER INTERVENTION, THE YG SHOWED A SIGNIFICANT DECREASE (P<0.05) IN THE MEAN SCORE IN ALL ASSESSED VARIABLES WHEN COMPARED WITH BASELINE DATA. IN ADDITION, STATISTICALLY SIGNIFICANT (P<0.05) DIFFERENCES WERE OBSERVED AMONG GROUPS AT THE END OF INTERVENTION IN DEPRESSION, ANXIETY, AND PAIN, BUT NOT IN DISABILITY. CONCLUSIONS: THE YOGA PROGRAM AND EDUCATION TOGETHER APPEAR TO BE EFFECTIVE IN REDUCING DEPRESSION AND ANXIETY, WHICH CAN AFFECT PERCEPTION OF PAIN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
19 1789  24 PRELIMINARY INDICATIONS OF THE EFFECT OF A BRIEF YOGA INTERVENTION ON MARKERS OF INFLAMMATION AND DNA METHYLATION IN CHRONICALLY STRESSED WOMEN. YOGA IS ASSOCIATED WITH REDUCED STRESS AND INCREASED WELL-BEING, ALTHOUGH THE MOLECULAR BASIS FOR THESE BENEFITS IS NOT CLEAR. MOUNTING EVIDENCE IMPLICATES THE IMMUNE RESPONSE, WITH CURRENT STUDIES FOCUSED ON PROTEIN IMMUNE MARKERS (SUCH AS CYTOKINES) IN CLINICAL POPULATIONS. TO EXPLORE THE MOLECULAR IMPACT, THIS PILOT STUDY USES A SUBSAMPLE (N=28) FROM A RANDOMISED WAITLIST CONTROL TRIAL INVESTIGATING THE IMPACT OF AN 8-WEEK YOGA INTERVENTION IN A COMMUNITY POPULATION OF WOMEN REPORTING PSYCHOLOGICAL DISTRESS (N=116). WE MEASURED INTERLEUKIN-6 (IL-6), TUMOUR NECROSIS FACTOR (TNF) AND C-REACTIVE PROTEIN (CRP) PROTEIN LEVELS, AND THE DNA METHYLATION OF THESE GENES AND THE GLOBAL INDICATOR, LINE-1. CORRELATIONS BETWEEN THESE AND PSYCHOLOGICAL VARIABLES WERE EXPLORED, IDENTIFYING MODERATE CORRELATIONS WITH CRP PROTEIN LEVELS, AND METHYLATION OF IL-6, CRP AND LINE-1. MANY CYTOKINE SAMPLES WERE BELOW DETECTION, HOWEVER A MANN-WHITNEY U DEMONSTRATED A TREND OF MODERATE BETWEEN-GROUP EFFECT FOR ELEVATED IL-6 IN THE YOGA GROUP. METHYLATION ANALYSES APPLIED CROSS-SECTIONAL AND NON-CONTROLLED LONGITUDINAL ANALYSES. WAIST-TO-HEIGHT RATIO AND AGE WERE COVARIED. WE DEMONSTRATED REDUCED METHYLATION OF THE TNF REGION IN THE YOGA GROUP RELATIVE TO THE WAITLIST CONTROL GROUP. NO OTHER GENES DEMONSTRATED A SIGNIFICANT DIFFERENCE. LONGITUDINAL ANALYSIS FURTHER SUPPORTED THESE RESULTS. THIS STUDY IS ONE OF THE FIRST TO EXPLORE YOGA AND IMMUNOLOGICAL MARKERS IN A NON-CLINICAL POPULATION, AND IS THE FIRST STUDY TO EXPLORE DNA METHYLATION. THESE FINDINGS INDICATE THAT FURTHER RESEARCH INTO MOLECULAR IMPACT OF YOGA ON MARKERS OF IMMUNE FUNCTION IS WARRANTED, WITH LARGER STUDIES REQUIRED.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
20 2851  34 YOGA, PHYSICAL THERAPY, AND BACK PAIN EDUCATION FOR SLEEP QUALITY IN LOW-INCOME RACIALLY DIVERSE ADULTS WITH CHRONIC LOW BACK PAIN: A SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: POOR SLEEP IS COMMON AMONG ADULTS WITH CHRONIC LOW BACK PAIN (CLBP), BUT THE INFLUENCE OF CLBP TREATMENTS, SUCH AS YOGA AND PHYSICAL THERAPY (PT), ON SLEEP QUALITY IS UNDER STUDIED. OBJECTIVE: EVALUATE THE EFFECTIVENESS OF YOGA AND PT FOR IMPROVING SLEEP QUALITY IN ADULTS WITH CLBP. DESIGN: SECONDARY ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL. SETTING: ACADEMIC SAFETY-NET HOSPITAL AND 7 AFFILIATED COMMUNITY HEALTH CENTERS. PARTICIPANTS: A TOTAL OF 320 ADULTS WITH CLBP. INTERVENTION: TWELVE WEEKLY YOGA CLASSES, 1-ON-1 PT SESSIONS, OR AN EDUCATIONAL BOOK. MAIN MEASURES: SLEEP QUALITY WAS MEASURED USING THE PITTSBURGH SLEEP QUALITY INDEX (PSQI) GLOBAL SCORE (0-21) AT BASELINE, 12 WEEKS, AND 52 WEEKS. ADDITIONALLY, WE ALSO EVALUATED HOW THE PROPORTION OF PARTICIPANTS WHO ACHIEVED A CLINICALLY MEANINGFUL IMPROVEMENT IN SLEEP QUALITY (> 3-POINT REDUCTION IN PSQI) AT 12 WEEKS VARIED BY CHANGES IN PAIN AND PHYSICAL FUNCTION AT 6 WEEKS. KEY RESULTS: AMONG PARTICIPANTS (MEAN AGE = 46.0, 64% FEMALE, 82% NON-WHITE), NEARLY ALL (92%) REPORTED POOR SLEEP QUALITY (PSQI > 5) AT BASELINE. AT 12 WEEKS, MODEST IMPROVEMENTS IN SLEEP QUALITY WERE OBSERVED AMONG THE YOGA (PSQI MEAN DIFFERENCE [MD] = - 1.19, 95% CONFIDENCE INTERVAL [CI] - 1.82, - 0.55) AND PT (PSQI MD = - 0.91, 95% CI - 1.61, - 0.20) GROUPS. PARTICIPANTS WHO REPORTED A >/= 30% IMPROVEMENT IN PAIN OR PHYSICAL FUNCTION AT 6 WEEKS, COMPARED WITH THOSE WHO IMPROVED < 10%, WERE MORE LIKELY TO BE A SLEEP QUALITY RESPONDER AT 12 WEEKS (ODDS RATIO [OR] = 3.51, 95% CI 1.73, 7.11 AND OR = 2.16, 95% CI 1.18, 3.95, RESPECTIVELY). RESULTS WERE SIMILAR AT 52 WEEKS. CONCLUSION: IN A SAMPLE OF ADULTS WITH CLBP, VIRTUALLY ALL WITH POOR SLEEP QUALITY PRIOR TO INTERVENTION, MODEST BUT STATISTICALLY SIGNIFICANT IMPROVEMENTS IN SLEEP QUALITY WERE OBSERVED WITH BOTH YOGA AND PT. IRRESPECTIVE OF TREATMENT, CLINICALLY IMPORTANT SLEEP IMPROVEMENTS AT THE END OF THE INTERVENTION WERE ASSOCIATED WITH MID-INTERVENTION PAIN AND PHYSICAL FUNCTION IMPROVEMENTS.
