1 2831 178 YOGA VS. PHYSICAL THERAPY VS. EDUCATION FOR CHRONIC LOW BACK PAIN IN PREDOMINANTLY MINORITY POPULATIONS: STUDY PROTOCOL FOR A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: CHRONIC LOW BACK PAIN CAUSES SUBSTANTIAL MORBIDITY AND COST TO SOCIETY WHILE DISPROPORTIONATELY IMPACTING LOW-INCOME AND MINORITY ADULTS. SEVERAL RANDOMIZED CONTROLLED TRIALS SHOW YOGA IS AN EFFECTIVE TREATMENT. HOWEVER, THE COMPARATIVE EFFECTIVENESS OF YOGA AND PHYSICAL THERAPY, A COMMON MAINSTREAM TREATMENT FOR CHRONIC LOW BACK PAIN, IS UNKNOWN. METHODS/DESIGN: THIS IS A RANDOMIZED CONTROLLED TRIAL FOR 320 PREDOMINANTLY LOW-INCOME MINORITY ADULTS WITH CHRONIC LOW BACK PAIN, COMPARING YOGA, PHYSICAL THERAPY, AND EDUCATION. INCLUSION CRITERIA ARE ADULTS 18-64 YEARS OLD WITH NON-SPECIFIC LOW BACK PAIN LASTING >/= 12 WEEKS AND A SELF-REPORTED AVERAGE PAIN INTENSITY OF >/= 4 ON A 0-10 SCALE. RECRUITMENT TAKES PLACE AT BOSTON MEDICAL CENTER, AN URBAN ACADEMIC SAFETY-NET HOSPITAL AND SEVEN FEDERALLY QUALIFIED COMMUNITY HEALTH CENTERS LOCATED IN DIVERSE NEIGHBORHOODS. THE 52-WEEK STUDY HAS AN INITIAL 12-WEEK TREATMENT PHASE WHERE PARTICIPANTS ARE RANDOMIZED IN A 2:2:1 RATIO INTO I) A STANDARDIZED WEEKLY HATHA YOGA CLASS SUPPLEMENTED BY HOME PRACTICE; II) A STANDARDIZED EVIDENCE-BASED EXERCISE THERAPY PROTOCOL ADAPTED FROM THE TREATMENT BASED CLASSIFICATION METHOD, INDIVIDUALLY DELIVERED BY A PHYSICAL THERAPIST AND SUPPLEMENTED BY HOME PRACTICE; AND III) EDUCATION DELIVERED THROUGH A SELF-CARE BOOK. CO-PRIMARY OUTCOME MEASURES ARE 12-WEEK PAIN INTENSITY MEASURED ON AN 11-POINT NUMERICAL RATING SCALE AND BACK-SPECIFIC FUNCTION MEASURED USING THE MODIFIED ROLAND MORRIS DISABILITY QUESTIONNAIRE. IN THE SUBSEQUENT 40-WEEK MAINTENANCE PHASE, YOGA PARTICIPANTS ARE RE-RANDOMIZED IN A 1:1 RATIO TO EITHER STRUCTURED MAINTENANCE YOGA CLASSES OR HOME PRACTICE ONLY. PHYSICAL THERAPY PARTICIPANTS ARE SIMILARLY RE-RANDOMIZED TO EITHER FIVE BOOSTER SESSIONS OR HOME PRACTICE ONLY. EDUCATION PARTICIPANTS CONTINUE TO FOLLOW RECOMMENDATIONS OF EDUCATIONAL MATERIALS. WE WILL ALSO ASSESS COST EFFECTIVENESS FROM THE PERSPECTIVES OF THE INDIVIDUAL, INSURERS, AND SOCIETY USING CLAIMS DATABASES, ELECTRONIC MEDICAL RECORDS, SELF-REPORT COST DATA, AND STUDY RECORDS. QUALITATIVE DATA FROM INTERVIEWS WILL ADD SUBJECTIVE DETAIL TO COMPLEMENT QUANTITATIVE DATA. TRIAL REGISTRATION: THIS TRIAL IS REGISTERED IN CLINICALTRIALS.GOV, WITH THE ID NUMBER: NCT01343927.	2014	
                                                                                                                                                                                                                                                  
2 2824  91 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.

3 2638  46 YOGA FOR VETERANS WITH CHRONIC LOW BACK PAIN: DESIGN AND METHODS OF A RANDOMIZED CLINICAL TRIAL. CHRONIC LOW BACK PAIN (CLBP) AFFLICTS MILLIONS OF PEOPLE WORLDWIDE, WITH PARTICULARLY HIGH PREVALENCE IN MILITARY VETERANS. MANY TREATMENT OPTIONS EXIST FOR CLBP, BUT MOST HAVE LIMITED EFFECTIVENESS AND SOME HAVE SIGNIFICANT SIDE EFFECTS. IN GENERAL POPULATIONS WITH CLBP, YOGA HAS BEEN SHOWN TO IMPROVE HEALTH OUTCOMES WITH FEW SIDE EFFECTS. HOWEVER, YOGA HAS NOT BEEN ADEQUATELY STUDIED IN MILITARY VETERAN POPULATIONS. IN THE CURRENT PAPER WE WILL DESCRIBE THE DESIGN AND METHODS OF A RANDOMIZED CLINICAL TRIAL AIMED AT EXAMINING WHETHER YOGA CAN EFFECTIVELY REDUCE DISABILITY AND PAIN IN US MILITARY VETERANS WITH CLBP. A TOTAL OF 144 US MILITARY VETERANS WITH CLBP WILL BE RANDOMIZED TO EITHER YOGA OR A DELAYED TREATMENT COMPARISON GROUP. THE YOGA INTERVENTION WILL CONSIST OF 2X WEEKLY YOGA CLASSES FOR 12WEEKS, COMPLEMENTED BY REGULAR HOME PRACTICE GUIDED BY A MANUAL. THE DELAYED TREATMENT GROUP WILL RECEIVE THE SAME INTERVENTION AFTER SIX MONTHS. THE PRIMARY OUTCOME IS THE CHANGE IN BACK PAIN-RELATED DISABILITY MEASURED WITH THE ROLAND-MORRIS DISABILITY QUESTIONNAIRE AT BASELINE AND 12-WEEKS. SECONDARY OUTCOMES INCLUDE PAIN INTENSITY, PAIN INTERFERENCE, DEPRESSION, ANXIETY, FATIGUE/ENERGY, QUALITY OF LIFE, SELF-EFFICACY, SLEEP QUALITY, AND MEDICATION USAGE. ADDITIONAL PROCESS AND/OR MEDIATIONAL FACTORS WILL BE MEASURED TO EXAMINE DOSE RESPONSE AND EFFECT MECHANISMS. ASSESSMENTS WILL BE CONDUCTED AT BASELINE, 6-WEEKS, 12-WEEKS, AND 6-MONTHS. ALL RANDOMIZED PARTICIPANTS WILL BE INCLUDED IN INTENTION-TO-TREAT ANALYSES. STUDY RESULTS WILL PROVIDE MUCH NEEDED EVIDENCE ON THE FEASIBILITY AND EFFECTIVENESS OF YOGA AS A THERAPEUTIC MODALITY FOR THE TREATMENT OF CLBP IN US MILITARY VETERANS.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
4  536  59 COMPARISON OF YOGA VERSUS STRETCHING FOR CHRONIC LOW BACK PAIN: PROTOCOL FOR THE YOGA EXERCISE SELF-CARE (YES) TRIAL. BACKGROUND: BACK PAIN, ONE OF THE MOST PREVALENT CONDITIONS AFFLICTING AMERICAN ADULTS, IS THE LEADING REASON FOR USING COMPLEMENTARY AND ALTERNATIVE MEDICINE (CAM) THERAPIES. YOGA IS AN INCREASINGLY POPULAR "MIND-BODY" CAM THERAPY OFTEN USED FOR RELIEVING BACK PAIN AND SEVERAL SMALL STUDIES HAVE FOUND YOGA EFFECTIVE FOR THIS CONDITION. THIS STUDY WILL ASSESS WHETHER YOGA IS EFFECTIVE FOR TREATING CHRONIC LOW BACK PAIN COMPARED WITH SELF CARE AND EXERCISE AND WILL EXPLORE THE MECHANISMS RESPONSIBLE FOR ANY OBSERVED BENEFITS. METHODS/DESIGN: A TOTAL OF 210 PARTICIPANTS WITH LOW BACK PAIN LASTING AT LEAST 3 MONTHS WILL BE RECRUITED FROM PRIMARY CARE CLINICS OF A LARGE HEALTHCARE SYSTEM BASED IN SEATTLE. THEY WILL BE RANDOMIZED IN A 2:2:1 RATIO TO RECEIVE 12 WEEKLY YOGA CLASSES, 12 WEEKLY CONVENTIONAL THERAPEUTIC EXERCISE CLASSES OF COMPARABLE PHYSICAL EXERTION, OR A SELF-CARE BOOK. INTERVIEWERS MASKED TO PARTICIPANTS' TREATMENT GROUP WILL ASSESS OUTCOMES AT BASELINE AND 6, 12 AND 26 WEEKS AFTER RANDOMIZATION. PRIMARY OUTCOMES WILL BE BACK-RELATED DYSFUNCTION AND SYMPTOM BOTHERSOMENESS. IN ADDITION, DATA WILL BE COLLECTED ON PHYSICAL MEASUREMENTS (E.G., FLEXION) AT BASELINE AND 12 WEEKS AND SALIVA SAMPLES WILL BE OBTAINED AT BASELINE, 6 AND 12 WEEKS. INFORMATION WILL BE COLLECTED ON SPECIFIC PHYSICAL, PSYCHOLOGICAL, AND PHYSIOLOGICAL FACTORS TO ALLOW EXPLORATION OF POSSIBLE MECHANISMS OF ACTION THROUGH WHICH YOGA COULD RELIEVE BACK PAIN AND DYSFUNCTION. THE EFFECTIVENESS OF YOGA WILL BE ASSESSED USING ANALYSIS OF COVARIANCE (USING GENERAL ESTIMATING EQUATIONS - GEE) WITHIN AN INTENTION-TO-TREAT CONTEXT. IF YOGA IS FOUND EFFECTIVE, FURTHER ANALYSES WILL EXPLORE WHETHER YOGA'S BENEFITS ARE ATTRIBUTABLE TO PHYSICAL, PSYCHOLOGICAL AND/OR PHYSIOLOGICAL FACTORS. CONCLUSIONS: THIS STUDY WILL PROVIDE THE CLEAREST EVIDENCE TO DATE ABOUT THE VALUE OF YOGA AS A THERAPEUTIC OPTION FOR TREATING CHRONIC BACK PAIN, AND IF THE RESULTS ARE POSITIVE, WILL HELP FOCUS FUTURE, MORE IN-DEPTH, RESEARCH ON THE MOST PROMISING POTENTIAL MECHANISMS OF ACTION IDENTIFIED BY THIS STUDY.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
5 1699  60 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	
                                                                                                                                                                                                                                                                                                                                                                                           
6 1787  47 PREFERENCE AND EXPECTATION FOR TREATMENT ASSIGNMENT IN A RANDOMIZED CONTROLLED TRIAL OF ONCE- VS TWICE-WEEKLY YOGA FOR CHRONIC LOW BACK PAIN. BACKGROUND: IN STUDIES INVOLVING NONPHARMACOLOGICAL COMPLEMENTARY AND ALTERNATIVE MEDICINE INTERVENTIONS, PARTICIPANT BLINDING IS VERY DIFFICULT. PARTICIPANT EXPECTATIONS MAY AFFECT PERCEIVED BENEFIT OF THERAPY. IN STUDIES OF YOGA AS TREATMENT FOR CHRONIC LOW BACK PAIN, LITTLE IS KNOWN ABOUT THE RELATIONSHIP BETWEEN PATIENT EXPECTATIONS AND PREFERENCES ON OUTCOMES. THIS STUDY WAS DESIGNED TO IDENTIFY BASELINE PREDICTORS OF PREFERENCE AND TO DETERMINE IF EXPECTATIONS AND PREFERENCES FOR DIFFERENT DOSES OF YOGA AFFECT BACK-RELATED FUNCTION AND LOW BACK PAIN INTENSITY. METHODS: THIS WAS A SECONDARY DATA ANALYSIS OF A 12-WEEK RANDOMIZED CONTROLLED TRIAL COMPARING ONCE-WEEKLY VS TWICE-WEEKLY YOGA FOR TREATMENT OF CHRONIC LOW BACK PAIN IN 93 ADULTS FROM A PREDOMINANTLY LOW-INCOME MINORITY POPULATION. AT BASELINE, PARTICIPANTS WERE ASKED ABOUT BACK FUNCTION, BACK PAIN, TREATMENT EXPECTATIONS, AND TREATMENT PREFERENCES. WE CREATED A VARIABLE "CONCORDANCE" TO DESCRIBE THE MATCHING OF PARTICIPANT PREFERENCE TO RANDOMIZED TREATMENT. OUR OUTCOME VARIABLES WERE CHANGE IN BACK FUNCTION AND PAIN INTENSITY AFTER 12 WEEKS OF YOGA INSTRUCTION. WE PERFORMED LOGISTIC REGRESSION TO IDENTIFY PREDICTORS OF PREFERENCE FOR ONCE- OR TWICE-WEEKLY YOGA INSTRUCTION. WE CREATED LINEAR REGRESSION MODELS TO IDENTIFY INDEPENDENT ASSOCIATIONS BETWEEN EXPECTATIONS, PREFERENCE, CONCORDANCE, AND OUTCOMES. RESULTS: WORSE BACK FUNCTION AT BASELINE WAS ASSOCIATED WITH 20% HIGHER ODDS OF PREFERRING TWICE-WEEKLY YOGA (OR 1.2, CI 1.1, 1.3). INDIVIDUALS WITH HIGHER EXPECTATION SCORES FOR TWICE-WEEKLY YOGA HAD 90% HIGHER ODDS OF PREFERRING TWICE-WEEKLY VS ONCE-WEEKLY YOGA (OR 1.9, CI 1.3, 2.7). INDIVIDUALS WITH HIGHER EXPECTATION SCORES FOR ONCE-WEEKLY YOGA HAD 40% LESS ODDS OF PREFERRING TWICE-WEEKLY YOGA (OR 0.6, CI 0.5, 0.9). AFTER CONTROLLING FOR BASELINE CHARACTERISTICS, WE FOUND NO STATISTICALLY SIGNIFICANT RELATIONSHIP BETWEEN TREATMENT OUTCOMES, PREFERENCE, EXPECTATION SCORES, OR CONCORDANCE. CONCLUSION: IN A POPULATION OF PREDOMINANTLY LOW-INCOME MINORITY PARTICIPANTS WITH CHRONIC LOW BACK PAIN, WORSE BACK FUNCTION WAS ASSOCIATED WITH PREFERENCE FOR MORE FREQUENT YOGA CLASSES. THOSE WHO PREFERRED MORE YOGA CLASSES HAD HIGHER EXPECTATIONS FOR THOSE CLASSES. TWELVE-WEEK CHANGE IN BACK PAIN INTENSITY AND BACK FUNCTION WERE NOT AFFECTED BY DOSING PREFERENCE, EXPECTATION SCORE, OR CONCORDANCE. MORE RESEARCH IS NEEDED TO BETTER MEASURE AND QUANTIFY PREFERENCE, EXPECTATIONS, AND THEIR RELATIONSHIP TO OUTCOMES IN YOGA RESEARCH.	2015	

7 1953  46 SECONDARY OUTCOMES FROM A RANDOMIZED CONTROLLED TRIAL OF YOGA FOR VETERANS WITH CHRONIC LOW-BACK PAIN. CHRONIC LOW-BACK PAIN (CLBP) IS A PREVALENT CONDITION, AND RATES ARE HIGHER AMONG MILITARY VETERANS. CLBP IS A PERSISTENT CONDITION, AND TREATMENT OPTIONS HAVE EITHER MODEST EFFECTS OR A SIGNIFICANT RISK OF SIDE-EFFECTS, WHICH HAS LED TO RECENT EFFORTS TO EXPLORE MIND-BODY INTERVENTION OPTIONS AND REDUCE OPIOID MEDICATION USE. PRIOR STUDIES OF YOGA FOR CLBP IN COMMUNITY SAMPLES, AND THE MAIN RESULTS OF A RECENT TRIAL WITH MILITARY VETERANS, INDICATE THAT YOGA CAN REDUCE BACK-RELATED DISABILITY AND PAIN INTENSITY. SECONDARY OUTCOMES FROM THE TRIAL OF YOGA WITH MILITARY VETERANS ARE PRESENTED HERE. IN THE STUDY, 150 MILITARY VETERANS (VETERANS ADMINISTRATION PATIENTS) WITH CLBP WERE RANDOMIZED TO EITHER YOGA OR A DELAYED-TREATMENT GROUP RECEIVING USUAL CARE BETWEEN 2013 AND 2015. ASSESSMENTS OCCURRED AT BASELINE, 6 WEEKS, 12 WEEKS, AND 6 MONTHS. INTENT-TO-TREAT ANALYSES WERE CONDUCTED. YOGA CLASSES LASTING 60 MINUTES EACH WERE OFFERED TWICE WEEKLY FOR 12 WEEKS. YOGA SESSIONS CONSISTED OF PHYSICAL POSTURES, MOVEMENT, FOCUSED ATTENTION, AND BREATHING TECHNIQUES. HOME PRACTICE GUIDED BY A MANUAL WAS STRONGLY RECOMMENDED. THE PRIMARY OUTCOME MEASURE WAS ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES AFTER 12 WEEKS. SECONDARY OUTCOMES INCLUDED PAIN INTENSITY, PAIN INTERFERENCE, DEPRESSION, FATIGUE, QUALITY OF LIFE, SELF-EFFICACY, AND MEDICATION USAGE. YOGA PARTICIPANTS IMPROVED MORE THAN DELAYED-TREATMENT PARTICIPANTS ON PAIN INTERFERENCE, FATIGUE, QUALITY OF LIFE, AND SELF-EFFICACY AT 12 WEEKS AND/OR 6 MONTHS. YOGA PARTICIPANTS HAD GREATER IMPROVEMENTS ACROSS A NUMBER OF IMPORTANT SECONDARY HEALTH OUTCOMES COMPARED TO CONTROLS. BENEFITS EMERGED DESPITE SOME VETERANS FACING CHALLENGES WITH ATTENDING YOGA SESSIONS IN PERSON. THE FINDINGS SUPPORT WIDER IMPLEMENTATION OF YOGA PROGRAMS FOR VETERANS, WITH ATTENTION TO INCREASING ACCESSIBILITY OF YOGA PROGRAMS IN THIS POPULATION.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
8  193  49 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 2596  51 YOGA FOR MILITARY VETERANS WITH CHRONIC LOW BACK PAIN: A RANDOMIZED CLINICAL TRIAL. INTRODUCTION: CHRONIC LOW BACK PAIN (CLBP) IS PREVALENT, ESPECIALLY AMONG MILITARY VETERANS. MANY CLBP TREATMENT OPTIONS HAVE LIMITED BENEFITS AND ARE ACCOMPANIED BY SIDE EFFECTS. MAJOR EFFORTS TO REDUCE OPIOID USE AND EMBRACE NONPHARMACOLOGICAL PAIN TREATMENTS HAVE RESULTED. RESEARCH WITH COMMUNITY CLBP PATIENTS INDICATES THAT YOGA CAN IMPROVE HEALTH OUTCOMES AND HAS FEW SIDE EFFECTS. THE BENEFITS OF YOGA AMONG MILITARY VETERANS WERE EXAMINED. DESIGN: PARTICIPANTS WERE RANDOMIZED TO EITHER YOGA OR DELAYED YOGA TREATMENT IN 2013-2015. OUTCOMES WERE ASSESSED AT BASELINE, 6 WEEKS, 12 WEEKS, AND 6 MONTHS. INTENTION-TO-TREAT ANALYSES OCCURRED IN 2016. SETTING/PARTICIPANTS: ONE HUNDRED AND FIFTY MILITARY VETERANS WITH CLBP WERE RECRUITED FROM A MAJOR VETERANS AFFAIRS MEDICAL CENTER IN CALIFORNIA. INTERVENTION: YOGA CLASSES (WITH HOME PRACTICE) WERE LED BY A CERTIFIED INSTRUCTOR TWICE WEEKLY FOR 12 WEEKS, AND CONSISTED PRIMARILY OF PHYSICAL POSTURES, MOVEMENT, AND BREATHING TECHNIQUES. MAIN OUTCOME MEASURES: THE PRIMARY OUTCOME WAS ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES AFTER 12 WEEKS. PAIN INTENSITY WAS IDENTIFIED AS AN IMPORTANT SECONDARY OUTCOME. RESULTS: PARTICIPANT CHARACTERISTICS WERE MEAN AGE 53 YEARS, 26% WERE FEMALE, 35% WERE UNEMPLOYED OR DISABLED, AND MEAN BACK PAIN DURATION WAS 15 YEARS. IMPROVEMENTS IN ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES DID NOT DIFFER BETWEEN THE TWO GROUPS AT 12 WEEKS, BUT YOGA PARTICIPANTS HAD GREATER REDUCTIONS IN ROLAND-MORRIS DISABILITY QUESTIONNAIRE SCORES THAN DELAYED TREATMENT PARTICIPANTS AT 6 MONTHS -2.48 (95% CI= -4.08, -0.87). YOGA PARTICIPANTS IMPROVED MORE ON PAIN INTENSITY AT 12 WEEKS AND AT 6 MONTHS. OPIOID MEDICATION USE DECLINED AMONG ALL PARTICIPANTS, BUT GROUP DIFFERENCES WERE NOT FOUND. CONCLUSIONS: YOGA IMPROVED HEALTH OUTCOMES AMONG VETERANS DESPITE EVIDENCE THEY HAD FEWER RESOURCES, WORSE HEALTH, AND MORE CHALLENGES ATTENDING YOGA SESSIONS THAN COMMUNITY SAMPLES STUDIED PREVIOUSLY. THE MAGNITUDE OF PAIN INTENSITY DECLINE WAS SMALL, BUT OCCURRED IN THE CONTEXT OF REDUCED OPIOID USE. THE FINDINGS SUPPORT WIDER IMPLEMENTATION OF YOGA PROGRAMS FOR VETERANS.

10  162  52 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	
                                                                                                                                                                                                                                                                                                                                                              
11  721  44 EFFECT OF IYENGAR YOGA THERAPY FOR CHRONIC LOW BACK PAIN. LOW BACK PAIN IS A SIGNIFICANT PUBLIC HEALTH PROBLEM AND ONE OF THE MOST COMMONLY REPORTED REASONS FOR THE USE OF COMPLEMENTARY ALTERNATIVE MEDICINE. A RANDOMIZED CONTROL TRIAL WAS CONDUCTED IN SUBJECTS WITH NON-SPECIFIC CHRONIC LOW BACK PAIN COMPARING IYENGAR YOGA THERAPY TO AN EDUCATIONAL CONTROL GROUP. BOTH PROGRAMS WERE 16 WEEKS LONG. SUBJECTS WERE PRIMARILY SELF-REFERRED AND SCREENED BY PRIMARY CARE PHYSICIANS FOR STUDY OF INCLUSION/EXCLUSION CRITERIA. THE PRIMARY OUTCOME FOR THE STUDY WAS FUNCTIONAL DISABILITY. SECONDARY OUTCOMES INCLUDING PRESENT PAIN INTENSITY, PAIN MEDICATION USAGE, PAIN-RELATED ATTITUDES AND BEHAVIORS, AND SPINAL RANGE OF MOTION WERE MEASURED BEFORE AND AFTER THE INTERVENTIONS. SUBJECTS HAD LOW BACK PAIN FOR 11.2+/-1.54 YEARS AND 48% USED PAIN MEDICATION. OVERALL, SUBJECTS PRESENTED WITH LESS PAIN AND LOWER FUNCTIONAL DISABILITY THAN SUBJECTS IN OTHER PUBLISHED INTERVENTION STUDIES FOR CHRONIC LOW BACK PAIN. OF THE 60 SUBJECTS ENROLLED, 42 (70%) COMPLETED THE STUDY. MULTIVARIATE ANALYSES OF OUTCOMES IN THE CATEGORIES OF MEDICAL, FUNCTIONAL, PSYCHOLOGICAL AND BEHAVIORAL FACTORS INDICATED THAT SIGNIFICANT DIFFERENCES BETWEEN GROUPS EXISTED IN FUNCTIONAL AND MEDICAL OUTCOMES BUT NOT FOR THE PSYCHOLOGICAL OR BEHAVIORAL OUTCOMES. UNIVARIATE ANALYSES OF MEDICAL AND FUNCTIONAL OUTCOMES REVEALED SIGNIFICANT REDUCTIONS IN PAIN INTENSITY (64%), FUNCTIONAL DISABILITY (77%) AND PAIN MEDICATION USAGE (88%) IN THE YOGA GROUP AT THE POST AND 3-MONTH FOLLOW-UP ASSESSMENTS. THESE PRELIMINARY DATA INDICATE THAT THE MAJORITY OF SELF-REFERRED PERSONS WITH MILD CHRONIC LOW BACK PAIN WILL COMPLY TO AND REPORT IMPROVEMENT ON MEDICAL AND FUNCTIONAL PAIN-RELATED OUTCOMES FROM IYENGAR YOGA THERAPY.	2005	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
12 2628  42 YOGA FOR THE MANAGEMENT OF PAIN AND SLEEP IN RHEUMATOID ARTHRITIS: A PILOT RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: THE AIM OF THE PRESENT STUDY WAS TO DETERMINE THE FEASIBILITY OF A RELAXATION-BASED YOGA INTERVENTION FOR RHEUMATOID ARTHRITIS, DESIGNED AND REPORTED IN ACCORDANCE WITH DELPHI RECOMMENDATIONS FOR YOGA INTERVENTIONS FOR MUSCULOSKELETAL CONDITIONS. METHODS: PARTICIPANTS WERE RECRUITED FROM A HOSPITAL DATABASE, AND RANDOMIZED TO EITHER EIGHT WEEKLY 75-MIN YOGA CLASSES OR A USUAL CARE CONTROL. FEASIBILITY WAS DETERMINED BY RECRUITMENT RATES, RETENTION, PROTOCOL ADHERENCE, PARTICIPANT SATISFACTION AND ADVERSE EVENTS. SECONDARY PHYSICAL AND PSYCHOSOCIAL OUTCOMES WERE ASSESSED USING SELF-REPORTED QUESTIONNAIRES AT BASELINE (WEEK 0), WEEK 9 (PRIMARY TIME POINT) AND WEEK 12 (FOLLOW-UP). RESULTS: OVER A 3-MONTH PERIOD, 26 PARTICIPANTS WITH MILD PAIN, MILD TO MODERATE FUNCTIONAL DISABILITY AND MODERATE DISEASE ACTIVITY WERE RECRUITED INTO THE STUDY (25% RECRUITMENT RATE). RETENTION RATES WERE 100% FOR YOGA PARTICIPANTS AND 92% FOR USUAL CARE PARTICIPANTS AT BOTH WEEKS 9 AND 12. PROTOCOL ADHERENCE AND PARTICIPANT SATISFACTION WERE HIGH. YOGA PARTICIPANTS ATTENDED A MEDIAN OF SEVEN CLASSES; ADDITIONALLY, SEVEN OF THE YOGA PARTICIPANTS (54%) REPORTED CONTINUING YOGA AT HOME DURING THE FOLLOW-UP PERIOD. NO SERIOUS ADVERSE EVENTS WERE RELATED TO THE STUDY. SECONDARY OUTCOMES SHOWED NO GROUP EFFECTS OF YOGA COMPARED WITH USUAL CARE. CONCLUSIONS: A RELAXATION-BASED YOGA PROGRAMME WAS FOUND TO BE FEASIBLE AND SAFE FOR PARTICIPANTS WITH RHEUMATOID ARTHRITIS-RELATED PAIN AND FUNCTIONAL DISABILITY. ADVERSE EVENTS WERE MINOR, AND NOT UNEXPECTED FROM AN INTERVENTION INCLUDING PHYSICAL COMPONENTS. THIS PILOT PROVIDES A FRAMEWORK FOR LARGER INTERVENTION STUDIES, AND SUPPORTS FURTHER EXPLORATION OF YOGA AS A COMPLEX INTERVENTION TO ASSIST WITH THE MANAGEMENT OF RHEUMATOID ARTHRITIS.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
13 2852  71 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.

14 1413  32 IMPLEMENTING YOGA INTO THE MANAGEMENT OF PATIENTS WITH REFRACTORY LOW BACK PAIN IN AN OUTPATIENT CLINIC SETTING. PURPOSE: TO EVALUATE THE EFFECTIVENESS OF IMPLEMENTING YOGA INTO THE TREATMENT OF PATIENTS WITH CHRONIC LOW BACK PAIN. DESIGN: QUANTITATIVE ANALYSIS WITH OPPORTUNITY FOR QUALITATIVE FEEDBACK. METHOD: EFFECTIVENESS OF THIS COMPLEMENTARY TREATMENT WAS ASSESSED USING A PRETEST/POSTTEST DESIGN OF PATIENTS WHO VOLUNTEERED TO PARTICIPATE IN YOGA CLASSES AS PART OF THEIR BACK PAIN MANAGEMENT. MEASUREMENTS INCLUDED LOW BACK PAIN RATING, PERCEPTION OF BACK PAIN INTERFERENCE WITH DAILY ACTIVITIES, AND SELF-EFFICACY IN DEALING WITH CHRONIC LOW BACK PAIN. FINDINGS: ALTHOUGH NO STATISTICALLY SIGNIFICANT FINDINGS WERE FOUND DUE TO THE SMALL SAMPLE SIZE, MOST PARTICIPANTS DEMONSTRATED IMPROVED INDIVIDUAL SCORES ON ALL MEASUREMENT SURVEYS INCLUDING QUALITATIVE COMMENTS. CONCLUSION: BASED ON THE FINDINGS OF THIS PILOT STUDY, FURTHER STUDIES ON IMPLEMENTING YOGA INTO THE TREATMENT OF CHRONIC LOW BACK PAIN ARE ENCOURAGED.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
15 2558  58 YOGA FOR CHRONIC LOW BACK PAIN IN A PREDOMINANTLY MINORITY POPULATION: A PILOT RANDOMIZED CONTROLLED TRIAL. BACKGROUND: SEVERAL STUDIES SUGGEST YOGA MAY BE EFFECTIVE FOR CHRONIC LOW BACK PAIN; HOWEVER, TRIALS TARGETING MINORITIES HAVE NOT BEEN CONDUCTED. PRIMARY STUDY OBJECTIVES: ASSESS THE FEASIBILITY OF STUDYING YOGA IN A PREDOMINANTLY MINORITY POPULATION WITH CHRONIC LOW BACK PAIN. COLLECT PRELIMINARY DATA TO PLAN A LARGER POWERED STUDY. STUDY DESIGN: PILOT RANDOMIZED CONTROLLED TRIAL. SETTING: TWO COMMUNITY HEALTH CENTERS IN A RACIALLY DIVERSE NEIGHBORHOOD OF BOSTON, MASSACHUSETTS. PARTICIPANTS: THIRTY ENGLISH-SPEAKING ADULTS (MEAN AGE 44 YEARS, 83% FEMALE, 83% RACIAL/ETHNIC MINORITIES; 48% WITH INCOMES < OR = $30,000) WITH MODERATE-TO-SEVERE CHRONIC LOW BACK PAIN. INTERVENTIONS: STANDARDIZED SERIES OF WEEKLY HATHA YOGA CLASSES FOR 12 WEEKS COMPARED TO A WAITLIST USUAL CARE CONTROL. OUTCOME MEASURES: FEASIBILITY MEASURED BY TIME TO COMPLETE ENROLLMENT, PROPORTION OF RACIAL/ETHNIC MINORITIES ENROLLED, RETENTION RATES, AND ADVERSE EVENTS. PRIMARY EFFICACY OUTCOMES WERE CHANGES FROM BASELINE TO 12 WEEKS IN PAIN SCORE (0=NO PAIN TO 10=WORST POSSIBLE PAIN) AND BACK-RELATED FUNCTION USING THE MODIFIED ROLAND-MORRIS DISABILITY QUESTIONNAIRE (0-23 POINT SCALE, HIGHER SCORES REFLECT POORER FUNCTION). SECONDARY EFFICACY OUTCOMES WERE ANALGESIC USE, GLOBAL IMPROVEMENT, AND QUALITY OF LIFE (SF-36). RESULTS: RECRUITMENT TOOK 2 MONTHS. RETENTION RATES WERE 97% AT 12 WEEKS AND 77% AT 26 WEEKS. MEAN PAIN SCORES FOR YOGA DECREASED FROM BASELINE TO 12 WEEKS (6.7 TO 4.4) COMPARED TO USUAL CARE, WHICH DECREASED FROM 7.5 TO 7.1 (P=.02). MEAN ROLAND SCORES FOR YOGA DECREASED FROM 14.5 TO 8.2 COMPARED TO USUAL CARE, WHICH DECREASED FROM 16.1 TO 12.5 (P=.28). AT 12 WEEKS, YOGA COMPARED TO USUAL CARE PARTICIPANTS REPORTED LESS ANALGESIC USE (13% VS 73%, P=.003), LESS OPIATE USE (0% VS 33%, P=.04), AND GREATER OVERALL IMPROVEMENT (73% VS 27%, P=.03). THERE WERE NO DIFFERENCES IN SF-36 SCORES AND NO SERIOUS ADVERSE EVENTS. CONCLUSION: A YOGA STUDY INTERVENTION IN A PREDOMINANTLY MINORITY POPULATION WITH CHRONIC LOW BACK PAIN WAS MODERATELY FEASIBLE AND MAY BE MORE EFFECTIVE THAN USUAL CARE FOR REDUCING PAIN AND PAIN MEDICATION USE.	2009	
                                                                                                                                                                                                                                                                                                                                                                                                                                      
16  521  52 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       
17 2830  45 YOGA VS STRETCHING IN VETERANS WITH CHRONIC LOWER BACK PAIN AND THE ROLE OF MINDFULNESS: A PILOT RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: THE PURPOSE OF THIS STUDY WAS TO INVESTIGATE THE FEASIBILITY OF RECRUITING, RANDOMIZING, ENROLLING, AND COLLECTING OUTCOME DATA ON VETERAN PATIENTS WITH CHRONIC LOW BACK PAIN (CLBP) WHO UNDERGO AN 8-WEEK, ACTIVE EXERCISE CLASS WITH MINDFULNESS (YOGA CLASS) AND WITHOUT (STRETCHING CLASS). METHODS: UNITED STATES VETERANS WITH CLBP BASED ON INCLUSION/EXCLUSION CRITERIA WERE RANDOMIZED TO 1 OF 2 GROUPS. THE STUDY DESIGN WAS A PILOT RANDOMIZED CONTROLLED TRIAL. TWENTY CLBP PATIENTS ATTENDED A YOGA CLASS OR STRETCHING CLASS ONCE PER WEEK FOR 8 WEEKS AT THE VETERANS AFFAIRS ROCHESTER OUTPATIENT CENTER, ROCHESTER, NEW YORK. THE FOLLOWING MEASUREMENTS WERE OBTAINED: RECRUITMENT OR ENROLLMENT DATA, COMPLIANCE DATA TO INCLUDE CLASS ATTENDANCE AND HOME EXERCISE, AND COMPLIANCE DATA REGARDING ABILITY TO COLLECT OUTCOME MEASURES AT BASELINE AND AT COMPLETION. OUTCOME MEASURES INCLUDED PAIN (PEG), QUALITY OF LIFE (PROMIS GLOBAL HEALTH SURVEY), SELF-EFFICACY (2-ITEM QUESTIONNAIRE), FEAR AVOIDANCE BELIEF, CATASTROPHIZING, AND SOCIAL ENGAGEMENT IN ADDITION TO QUALITATIVE CLINICIAN OPEN-ENDED QUESTIONS POSTINTERVENTION. RESULTS: FORTY-FIVE VETERANS WERE QUERIED REGARDING INTEREST IN PARTICIPATION. OF THESE, 34 (76%) MET THE STUDY'S CRITERIA. TWENTY (44%) AGREED TO PARTICIPATE AND WERE CONSENTED, RANDOMIZED, AND ENROLLED IN THE STUDY. INITIAL AND FINAL OUTCOME MEASURES WERE OBTAINED FOR EACH PARTICIPANT (100%). FORTY PERCENT ATTENDED MORE THAN 80% OF THE SESSIONS FOR BOTH YOGA AND STRETCHING GROUPS. CONCLUSION: THIS PILOT STUDY DEMONSTRATED FEASIBILITY OF RECRUITING, ENROLLING, AND COLLECTING OUTCOME DATA ON CLBP VETERAN PATIENTS PARTICIPATING IN YOGA AND STRETCHING CLASS. THE DATA FROM THIS PILOT WILL INFORM THE DEVELOPMENT OF A RANDOMIZED, COMPARATIVE EFFECTIVENESS STUDY OF YOGA WITH AND WITHOUT MINDFULNESS IN THE MANAGEMENT OF CLBP.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
18 1488  36 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.

19 1180  48 EVALUATION OF THE EFFECTIVENESS AND EFFICACY OF IYENGAR YOGA THERAPY ON CHRONIC LOW BACK PAIN. STUDY DESIGN: THE EFFECTIVENESS AND EFFICACY OF IYENGAR YOGA FOR CHRONIC LOW BACK PAIN (CLBP) WERE ASSESSED WITH INTENTION-TO-TREAT AND PER-PROTOCOL ANALYSIS. NINETY SUBJECTS WERE RANDOMIZED TO A YOGA (N = 43) OR CONTROL GROUP (N = 47) RECEIVING STANDARD MEDICAL CARE. PARTICIPANTS WERE FOLLOWED 6 MONTHS AFTER COMPLETION OF THE INTERVENTION. OBJECTIVE: THIS STUDY AIMED TO EVALUATE IYENGAR YOGA THERAPY ON CHRONIC LOW BACK PAIN. YOGA SUBJECTS WERE HYPOTHESIZED TO REPORT GREATER REDUCTIONS IN FUNCTIONAL DISABILITY, PAIN INTENSITY, DEPRESSION, AND PAIN MEDICATION USAGE THAN CONTROLS. SUMMARY OF BACKGROUND DATA: CLBP IS A MUSCULOSKELETAL DISORDER WITH PUBLIC HEALTH AND ECONOMIC IMPACT. PILOT STUDIES OF YOGA AND BACK PAIN HAVE REPORTED SIGNIFICANT CHANGES IN CLINICALLY IMPORTANT OUTCOMES. METHODS: SUBJECTS WERE RECRUITED THROUGH SELF-REFERRAL AND HEALTH PROFESSIONAL REFERRALS ACCORDING TO EXPLICIT INCLUSION/EXCLUSION CRITERIA. YOGA SUBJECTS PARTICIPATED IN 24 WEEKS OF BIWEEKLY YOGA CLASSES DESIGNED FOR CLBP. OUTCOMES WERE ASSESSED AT 12 (MIDWAY), 24 (IMMEDIATELY AFTER), AND 48 WEEKS (6-MONTH FOLLOW-UP) AFTER THE START OF THE INTERVENTION USING THE OSWESTRY DISABILITY QUESTIONNAIRE, A VISUAL ANALOG SCALE, THE BECK DEPRESSION INVENTORY, AND A PAIN MEDICATION-USAGE QUESTIONNAIRE. RESULTS: USING INTENTION-TO-TREAT ANALYSIS WITH REPEATED MEASURES ANOVA (GROUP X TIME), SIGNIFICANTLY GREATER REDUCTIONS IN FUNCTIONAL DISABILITY AND PAIN INTENSITY WERE OBSERVED IN THE YOGA GROUP WHEN COMPARED TO THE CONTROL GROUP AT 24 WEEKS. A SIGNIFICANTLY GREATER PROPORTION OF YOGA SUBJECTS ALSO REPORTED CLINICAL IMPROVEMENTS AT BOTH 12 AND 24 WEEKS. IN ADDITION, DEPRESSION WAS SIGNIFICANTLY LOWER IN YOGA SUBJECTS. FURTHERMORE, WHILE A REDUCTION IN PAIN MEDICATION OCCURRED, THIS WAS COMPARABLE IN BOTH GROUPS. WHEN RESULTS WERE ANALYZED USING PER-PROTOCOL ANALYSIS, IMPROVEMENTS WERE OBSERVED FOR ALL OUTCOMES IN THE YOGA GROUP, INCLUDING AGREATER TREND FOR REDUCED PAIN MEDICATION USAGE. ALTHOUGH SLIGHTLY LESS THAN AT 24 WEEKS, THE YOGA GROUP HAD STATISTICALLY SIGNIFICANT REDUCTIONS IN FUNCTIONAL DISABILITY, PAIN INTENSITY, AND DEPRESSION COMPARED TO STANDARD MEDICAL CARE 6-MONTHS POSTINTERVENTION. CONCLUSION: YOGA IMPROVES FUNCTIONAL DISABILITY, PAIN INTENSITY, AND DEPRESSION IN ADULTS WITH CLBP. THERE WAS ALSO A CLINICALLY IMPORTANT TREND FOR THE YOGA GROUP TO REDUCE THEIR PAIN MEDICATION USAGE COMPARED TO THE CONTROL GROUP.	2009	
                                                                                                                                          
20 2322  45 TREATMENT OF CHRONIC LOWER BACK PAIN: STUDY PROTOCOL OF A COMPARATIVE EFFECTIVENESS STUDY ON YOGA, EURYTHMY THERAPY, AND PHYSIOTHERAPEUTIC EXERCISES. BACKGROUND: WE AIM TO COMPARE THE EFFECTIVENESS OF 3 ACTIVE INTERVENTIONS, I.E., YOGA, EURYTHMY THERAPY, AND PHYSIOTHERAPEUTIC EXERCISE, ON CHRONIC LOWER BACK PAIN. METHODS: IN THIS RANDOMIZED CONTROLLED TRIAL OVER 16 WEEKS (8 WEEKS OF INTERVENTION, 8 WEEKS OF FOLLOW-UP), DATA OF INDIVIDUALS WITH CHRONIC LOWER BACK PAIN WILL BE ANALYZED. INTERVENTIONS ARE IMPLEMENTED AS GROUP SESSIONS (75 MIN) ONCE PER WEEK. PARTICIPANTS RECEIVE A MANUAL FOR HOME-BASED PRACTICE AND ARE ASSESSED BEFORE AND AT THE END OF THE 8-WEEK INTERVENTION PERIOD, AND AT THE END OF AN 8-WEEK FOLLOW-UP PERIOD. STANDARDIZED QUESTIONNAIRES ARE: THE ROLAND-MORRIS DISABILITY SCORE, VISUAL ANALOG SCALES MEASURING INTENSITY OF PAIN, THE BRIEF MULTIDIMENSIONAL LIFE SATISFACTION SCALE, THE PERCEIVED STRESS SCALE, THE INNER CORRESPONDENCE WITH THE PRACTICES QUESTIONNAIRE, THE FREIBURG MINDFULNESS QUESTIONNAIRE, THE GENERAL SELF-EFFICACY SCALE, A SELF-REGULATION QUESTIONNAIRE, THE INTERNAL COHERENCE SCALE, A PAIN DIARY (REGISTERING THE NEED OF ANALGESIC MEDICATION), AND A QUESTIONNAIRE ON THE PATIENTS' EXPECTATION THAT THE INTERVENTIONS WILL BE EFFECTIVE IN REDUCING PAIN AND HOW STRONG THIS REDUCTION MIGHT BE (2 SINGLE ITEMS), ETC. DISCUSSION: THIS LARGE MULTICENTER STUDY WILL PROVIDE EVIDENCE ON THE EFFECTIVENESS OF 3 CONTRASTING MOVEMENT-ORIENTATED TREATMENTS THAT SHARE SOME SIMILARITIES BUT DIFFER IN ESSENTIAL DETAILS: YOGA, EURYTHMY THERAPY, AND PHYSIOTHERAPEUTIC EXERCISES. IT WILL PROVIDE IMPORTANT DATA ON NON-PHARMACOLOGICAL OPTIONS TO TREAT LOWER BACK PAIN IN A LARGE GROUP OF AFFECTED INDIVIDUALS.	2018
