1  408 145 BIOMECHANICAL CHARACTERISTICS ON THE LOWER EXTREMITY OF THREE TYPICAL YOGA MANOEUVRES. THIS STUDY WAS AIMED AT EXPLORING THE BIOMECHANICAL CHARACTERISTICS OF THE LOWER EXTREMITY AMONGST THREE TYPICAL YOGA MANOEUVRES. A TOTAL OF THIRTEEN EXPERIENCED FEMALE YOGA PRACTITIONERS WERE RECRUITED IN THE CURRENT STUDY; THEY WERE ALL CERTIFIED WITH THE YOGA ALLIANCE. A THREE-DIMENSIONAL MOTION CAPTURE SYSTEM WITH 10 CAMERAS COMBINED WITH FOUR SYNCHRONISED FORCE PLATES WAS USED TO COLLECT KINEMATICS OF THE LOWER EXTREMITY AND GROUND REACTIVE FORCE WHILST THE PARTICIPANTS PERFORMED THE CRESCENT LUNGE POSE, WARRIOR II POSE, AND TRIANGLE POSE. ONE-WAY REPEATED ANOVA WAS USED IN EXPLORING THE DIFFERENCES AMONGST THE THREE YOGA MOVEMENTS, AND THE SIGNIFICANCE WAS SET TO ALPHA < 0.05. THE TRIANGLE POSE PERFORMED THE LARGEST RANGE OF MOTION (ROM) OF THE HIP (90.5 DEGREES +/- 22.9 DEGREES ), KNEE (68.8 DEGREES +/- 23.1 DEGREES ), AND ANKLE (46.4 DEGREES +/- 11.3 DEGREES ) IN THE SAGITTAL PLANE AND THE HIP (54.8 DEGREES +/- 6.5 DEGREES ), KNEE (42.4 DEGREES +/- 12.8 DEGREES ), AND ANKLE (4.8 DEGREES +/- 1.7 DEGREES ) IN THE FRONTAL PLANE AMONGST THE THREE MANOEUVRES (P < 0.05). NO SIGNIFICANT DIFFERENCE WAS FOUND FOR THE HIP AND ANKLE JOINT MOMENT AMONGST THE THREE MANOEUVRES (P > 0.05). KNEE JOINT TRAVELLED INTO 9.5 DEGREES OF EXTENSION AND SLIGHT ADDUCTION OF 1.94 DEGREES WHILST EXPRESSING THE LARGEST KNEE JOINT ADDUCTION MOMENTS (0.30 +/- 0.22 NM/KG) IN THE TRIANGLE POSE. THE DISTRIBUTION OF THE ANGULAR IMPULSE OF THE LOWER LIMB JOINTS INDICATED THAT THE HIP JOINT CONTRIBUTED SIGNIFICANTLY THE MOST IN THE SAGITTAL AND FRONTAL PLANES OF THE THREE YOGA MANOEUVRES (P < 0.05), RANGING FROM 51.67% TO 70.56%. RESULTS INDICATED THAT TRIANGLE POSE MAY BE SUPERIOR TO THE OTHER TWO MANOEUVRES, WHICH IMPROVED HIP JOINT ROM, STRENGTH, AND DYNAMIC STABILITY. HOWEVER, KNEE INJURIES SUCH AS OSTEOARTHRITIS (OA) SHOULD BE CONSIDERED BECAUSE OF THE LARGE KNEE EXTENSOR ANGLE AND ADDUCTOR MOMENTS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
2 2064  43 THE BIOMECHANICAL DEMANDS OF STANDING YOGA POSES IN SENIORS: THE YOGA EMPOWERS SENIORS STUDY (YESS). BACKGROUND: THE NUMBER OF OLDER ADULTS PARTICIPATING IN YOGA HAS INCREASED DRAMATICALLY IN RECENT YEARS; YET, THE PHYSICAL DEMANDS ASSOCIATED WITH YOGA PERFORMANCE HAVE NOT BEEN REPORTED. THE PRIMARY AIM OF THE YOGA EMPOWERS SENIORS STUDY (YESS) WAS TO USE BIOMECHANICAL METHODS TO QUANTIFY THE PHYSICAL DEMANDS ASSOCIATED WITH THE PERFORMANCE OF 7 COMMONLY-PRACTICED STANDING YOGA POSES IN OLDER ADULTS. METHODS: 20 AMBULATORY OLDER ADULTS (70.7+-3.8 YRS) ATTENDED 2 WEEKLY 60-MINUTE HATHA YOGA CLASSES FOR 32 WEEKS. THE LOWER-EXTREMITY NET JOINT MOMENTS OF FORCE (JMOFS), WERE OBTAINED DURING THE PERFORMANCE OF THE FOLLOWING POSES: CHAIR, WALL PLANK, TREE, WARRIOR II, SIDE STRETCH, CRESCENT, AND ONE-LEGGED BALANCE. REPEATED-MEASURE ANOVA AND TUKEY'S POST-HOC TESTS WERE USED TO IDENTIFY DIFFERENCES IN JMOFS AMONG THE POSES. ELECTROMYOGRAPHIC ANALYSIS WAS USED TO SUPPORT THE JMOF FINDINGS. RESULTS: THERE WAS A SIGNIFICANT MAIN EFFECT FOR POSE, AT THE ANKLE, KNEE AND HIP, IN THE FRONTAL AND SAGITTAL PLANES (P=0.00-0.03). THE CRESCENT, CHAIR, WARRIOR II, AND ONE-LEGGED BALANCE POSES GENERATED THE GREATEST AVERAGE SUPPORT MOMENTS. SIDE STRETCH GENERATED THE GREATEST AVERAGE HIP EXTENSOR AND KNEE FLEXOR JMOFS. CRESCENT PLACED THE HIGHEST DEMANDS ON THE HIP FLEXORS AND KNEE EXTENSORS. ALL OF THE POSES PRODUCED ANKLE PLANTAR-FLEXOR JMOFS. IN THE FRONTAL PLANE, THE TREE GENERATED THE GREATEST AVERAGE HIP AND KNEE ABDUCTOR JMOFS; WHEREAS WARRIOR II GENERATED THE GREATEST AVERAGE HIP AND KNEE ADDUCTOR JMOFS. WARRIOR II AND ONE-LEGGED BALANCE INDUCED THE LARGEST AVERAGE ANKLE EVERTOR AND INVERTOR JMOFS, RESPECTIVELY. THE ELECTROMYOGRAPHIC FINDINGS WERE CONSISTENT WITH THE JMOF RESULTS. CONCLUSIONS: MUSCULOSKELETAL DEMAND VARIED SIGNIFICANTLY ACROSS THE DIFFERENT POSES. THESE FINDINGS MAY BE USED TO GUIDE THE DESIGN OF EVIDENCE-BASED YOGA INTERVENTIONS THAT ADDRESS INDIVIDUAL-SPECIFIC TRAINING AND REHABILITATION GOALS IN SENIORS.

3  253  40 A YOGA STRENGTHENING PROGRAM DESIGNED TO MINIMIZE THE KNEE ADDUCTION MOMENT FOR WOMEN WITH KNEE OSTEOARTHRITIS: A PROOF-OF-PRINCIPLE COHORT STUDY. UNLABELLED: PEOPLE WITH KNEE OSTEOARTHRITIS MAY BENEFIT FROM EXERCISE PRESCRIPTIONS THAT MINIMIZE KNEE LOADS IN THE FRONTAL PLANE. THE PRIMARY OBJECTIVE OF THIS STUDY WAS TO DETERMINE WHETHER A NOVEL 12-WEEK STRENGTHENING PROGRAM DESIGNED TO MINIMIZE EXPOSURE TO THE KNEE ADDUCTION MOMENT (KAM) COULD IMPROVE SYMPTOMS AND KNEE STRENGTH IN WOMEN WITH SYMPTOMATIC KNEE OSTEOARTHRITIS. A SECONDARY OBJECTIVE WAS TO DETERMINE WHETHER THE PROGRAM COULD IMPROVE MOBILITY AND FITNESS, AND DECREASE PEAK KAM DURING GAIT. THE TERTIARY OBJECTIVE WAS TO EVALUATE THE BIOMECHANICAL CHARACTERISTICS OF THIS YOGA PROGRAM. IN PARTICULAR, WE COMPARED THE PEAK KAM DURING GAIT WITH THAT DURING YOGA POSTURES AT BASELINE. WE ALSO COMPARED LOWER LIMB NORMALIZED MEAN ELECTROMYOGRAPHY (EMG) AMPLITUDES DURING YOGA POSTURES BETWEEN BASELINE AND FOLLOW-UP. PRIMARY MEASURES INCLUDED SELF-REPORTED PAIN AND PHYSICAL FUNCTION (KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCORE) AND KNEE STRENGTH (EXTENSOR AND FLEXOR TORQUES). SECONDARY MEASURES INCLUDED MOBILITY (SIX-MINUTE WALK, 30-SECOND CHAIR STAND, STAIR CLIMBING), FITNESS (SUBMAXIMAL CYCLE ERGOMETER TEST), AND CLINICAL GAIT ANALYSIS USING MOTION CAPTURE SYNCHRONIZED WITH ELECTROMYOGRAPHY AND FORCE MEASUREMENT. ALSO, KAM AND NORMALIZED MEAN EMG AMPLITUDES WERE COLLECTED DURING YOGA POSTURES. FORTY-FIVE WOMEN OVER AGE 50 WITH SYMPTOMATIC KNEE OSTEOARTHRITIS, CONSISTENT WITH THE AMERICAN COLLEGE OF RHEUMATOLOGY CRITERIA, ENROLLED IN OUR 12-WEEK (3 SESSIONS PER WEEK) PROGRAM. DATA FROM 38 WERE ANALYZED (SIX DROP-OUTS; ONE LOST TO CO-INTERVENTION). PARTICIPANTS EXPERIENCED REDUCED PAIN (MEAN IMPROVEMENT 10.1-20.1 NORMALIZED TO 100; P<0.001), INCREASED KNEE EXTENSOR STRENGTH (MEAN IMPROVEMENT 0.01 NM/KG; P = 0.004), AND INCREASED FLEXOR STRENGTH (MEAN IMPROVEMENT 0.01 NM/KG; P = 0.001) AT FOLLOW-UP COMPARED TO BASELINE. PARTICIPANTS IMPROVED MOBILITY ON THE SIX-MINUTE WALK (MEAN IMPROVEMENT 37.7 M; P<0.001) AND 30-SECOND CHAIR STAND (MEAN IMPROVEMENT 1.3; P = 0.006) AT FOLLOW-UP COMPARED TO BASELINE. FITNESS AND PEAK KAM DURING GAIT WERE UNCHANGED BETWEEN BASELINE AND FOLLOW-UP. AVERAGE KAM DURING THE YOGA POSTURES WERE LOWER THAN THAT OF NORMAL GAIT. NORMALIZED MEAN EMG AMPLITUDES DURING YOGA POSTURES WERE UP TO 31.0% OF MAXIMUM BUT DID NOT CHANGE BETWEEN BASELINE AND FOLLOW-UP. IN THIS COHORT STUDY, THE YOGA-BASED STRENGTHENING POSTURES THAT ELICIT LOW KAMS IMPROVED KNEE SYMPTOMS AND STRENGTH IN WOMEN WITH KNEE OA FOLLOWING A 12 WEEK PROGRAM (3 SESSIONS PER WEEK). THE PROGRAM ALSO IMPROVED MOBILITY, BUT DID NOT IMPROVE FITNESS OR REDUCE PEAK KAM DURING GAIT. THE KAM DURING THE YOGA POSTURES WERE LOWER THAN THAT OF NORMAL GAIT. OVERALL, THE PROPOSED PROGRAM MAY BE USEFUL IN IMPROVING PAIN, STRENGTH, AND MOBILITY IN WOMEN WITH KNEE OSTEOARTHRITIS. CLINICAL EFFICACY NEEDS TO BE ASSESSED USING A RANDOMIZED CONTROLLED TRIAL DESIGN. TRIAL REGISTRATION: CLINICALTRIALS.GOV NCT02146105.	2015	

4 1348  31 IDENTIFYING YOGA-BASED KNEE STRENGTHENING EXERCISES USING THE KNEE ADDUCTION MOMENT. BACKGROUND: THIS STUDY AIMED TO COMPARE MUSCLE ACTIVATIONS, CO-CONTRACTION INDICES, AND THE KNEE ADDUCTION MOMENT BETWEEN STATIC STANDING YOGA POSTURES TO IDENTIFY APPROPRIATE EXERCISES FOR KNEE OSTEOARTHRITIS. METHODS: HEALTHY YOUNG WOMEN (24.4 (5.4) YEARS, 23.1 (3.7) KG/M(2)) PARTICIPATED. PRIMARY OUTCOME VARIABLES WERE ELECTROMYOGRAPHIC ACTIVATIONS OF THE VASTUS LATERALIS, RECTUS FEMORIS, VASTUS MEDIALIS, BICEPS FEMORIS, AND SEMITENDINOSUS; CO-CONTRACTION BETWEEN THE BICEPS FEMORIS AND RECTUS FEMORIS, AND VASTUS LATERALIS AND VASTUS MEDIALIS; AND KNEE ADDUCTION MOMENTS OF BOTH LEGS DURING SIX STATIC, STANDING YOGA POSTURES (TWO SQUATTING POSTURES, TWO LUNGING POSTURES, A HAMSTRING STRETCH, AND A SINGLE-LEG BALANCE POSTURE). A TWO-FACTOR REPEATED MEASURES ANALYSIS OF VARIANCE WAS USED TO IDENTIFY DIFFERENCES IN MUSCLE AMPLITUDES, CO-CONTRACTIONS, AND KNEE ADDUCTION MOMENT BETWEEN POSTURES AND LEGS. FINDINGS: QUADRICEPS ACTIVATIONS WERE HIGHEST DURING SQUAT AND LUNGE POSTURES (P</=0.001). HAMSTRING ACTIVATIONS WERE HIGHEST DURING THE HAMSTRING STRETCH (P</=0.003). SQUAT AND LUNGE POSTURES PRODUCED HIGHER CO-CONTRACTION INDICES THAN OTHER POSTURES (P</=0.011). THE WIDE LEGGED SQUAT (GODDESS) AND LUNGE WITH TRUNK UPRIGHT (WARRIOR) PRODUCED THE LOWEST KNEE ADDUCTION MOMENTS (P</=0.006), WHILE THE SINGLE-LEG BALANCE POSTURE ELICITED A HIGHER KNEE ADDUCTION MOMENT THAN ALL OTHER POSTURES (P<0.05). INTERPRETATION: SQUATTING AND LUNGING POSTURES COULD IMPROVE LEG STRENGTH WHILE POTENTIALLY MINIMIZING EXPOSURE TO HIGH KNEE ADDUCTION MOMENTS. FUTURE WORK SHOULD EVALUATE WHETHER THESE EXERCISES ARE USEFUL IN PEOPLE WITH KNEE OSTEOARTHRITIS.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
5 1113  36 EFFICACY OF A BIOMECHANICALLY-BASED YOGA EXERCISE PROGRAM IN KNEE OSTEOARTHRITIS: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: CERTAIN EXERCISES COULD OVERLOAD THE OSTEOARTHRITIC KNEE. WE DEVELOPED AN EXERCISE PROGRAM FROM YOGA POSTURES WITH A MINIMAL KNEE ADDUCTION MOMENT FOR KNEE OSTEOARTHRITIS. THE PURPOSE WAS TO COMPARE THE EFFECTIVENESS OF THIS BIOMECHANICALLY-BASED YOGA EXERCISE (YE), WITH TRADITIONAL EXERCISE (TE), AND A NO-EXERCISE ATTENTION-EQUIVALENT CONTROL (NE) FOR IMPROVING PAIN, SELF-REPORTED PHYSICAL FUNCTION AND MOBILITY PERFORMANCE IN WOMEN WITH KNEE OSTEOARTHRITIS. DESIGN: SINGLE-BLIND, THREE-ARM RANDOMIZED CONTROLLED TRIAL. SETTING: COMMUNITY IN SOUTHWESTERN ONTARIO, CANADA. PARTICIPANTS: A CONVENIENCE SAMPLE OF 31 WOMEN WITH SYMPTOMATIC KNEE OSTEOARTHRITIS WAS RECRUITED THROUGH RHEUMATOLOGY, ORTHOPAEDIC AND PHYSIOTHERAPY CLINICS, NEWSPAPERS AND WORD-OF-MOUTH. INTERVENTIONS: PARTICIPANTS WERE STRATIFIED BY DISEASE SEVERITY AND RANDOMLY ALLOCATED TO ONE OF THREE 12-WEEK, SUPERVISED INTERVENTIONS. YE INCLUDED BIOMECHANICALLY-BASED YOGA EXERCISES; TE INCLUDED TRADITIONAL LEG STRENGTHENING ON MACHINES; AND NE INCLUDED MEDITATION WITH NO EXERCISE. PARTICIPANTS WERE ASKED TO ATTEND THREE 1-HOUR GROUP CLASSES/SESSIONS EACH WEEK. MEASUREMENTS: PRIMARY OUTCOMES WERE PAIN, SELF-REPORTED PHYSICAL FUNCTION AND MOBILITY PERFORMANCE. SECONDARY OUTCOMES WERE KNEE STRENGTH, DEPRESSION, AND HEALTH-RELATED QUALITY OF LIFE. ALL WERE ASSESSED BY A BLINDED ASSESSOR AT BASELINE AND IMMEDIATELY FOLLOWING THE INTERVENTION. RESULTS: THE YE GROUP DEMONSTRATED GREATER IMPROVEMENTS IN KOOS PAIN (MEAN DIFFERENCE OF 22.9 [95% CI, 6.9 TO 38.8; P = 0.003]), INTERMITTENT PAIN (MEAN DIFFERENCE OF -19.6 [95% CI, -34.8 TO -4.4; P = 0.009]) AND SELF-REPORTED PHYSICAL FUNCTION (MEAN DIFFERENCE OF 17.2 [95% CI, 5.2 TO 29.2; P = 0.003]) COMPARED TO NE. IMPROVEMENTS IN THESE OUTCOMES WERE SIMILAR BETWEEN YE AND TE. HOWEVER, TE DEMONSTRATED A GREATER IMPROVEMENT IN KNEE FLEXOR STRENGTH COMPARED TO YE (MEAN DIFFERENCE OF 0.1 [95% CI, 0.1 TO 0.2]. IMPROVEMENTS FROM BASELINE TO FOLLOW-UP WERE PRESENT IN QUALITY OF LIFE SCORE FOR YE AND KNEE FLEXOR STRENGTH FOR TE, WHILE BOTH ALSO DEMONSTRATED IMPROVEMENTS IN MOBILITY. NO IMPROVEMENT IN ANY OUTCOME WAS PRESENT IN NE. CONCLUSIONS: THE BIOMECHANICALLY-BASED YOGA EXERCISE PROGRAM PRODUCED CLINICALLY MEANINGFUL IMPROVEMENTS IN PAIN, SELF-REPORTED PHYSICAL FUNCTION AND MOBILITY IN WOMEN WITH CLINICAL KNEE OA COMPARED TO NO EXERCISE. WHILE NOT STATISTICALLY SIGNIFICANT, IMPROVEMENTS IN THESE OUTCOMES WERE LARGER THAN THOSE ELICITED FROM THE TRADITIONAL EXERCISE-BASED PROGRAM. THOUGH THIS MAY SUGGEST THAT THE YOGA PROGRAM MAY BE MORE EFFICACIOUS FOR KNEE OA, FUTURE RESEARCH STUDYING A LARGER SAMPLE IS REQUIRED.

6 2306  45 TRAINING BENEFITS AND INJURY RISKS OF STANDING YOGA APPLIED IN MUSCULOSKELETAL PROBLEMS: LOWER LIMB BIOMECHANICAL ANALYSIS. STANDING YOGA POSES STRENGTHEN A PERSON'S LEGS AND HELPS TO ACHIEVE THE GOAL OF MUSCULOSKELETAL REHABILITATION, BUT INADEQUATE EXERCISE PLANNING CAN CAUSE INJURIES. THIS STUDY INVESTIGATED CHANGES IN THE ELECTROMYOGRAM AND JOINT MOMENTS OF FORCE (JMOFS) OF LOWER EXTREMITIES DURING COMMON STANDING YOGA POSES IN ORDER TO EXPLORE THE FEASIBILITY AND POSSIBLE INJURY RISK IN DEALING WITH MUSCULOSKELETAL PROBLEMS. ELEVEN YOGA INSTRUCTORS WERE RECRUITED TO EXECUTE FIVE YOGA POSES (CHAIR, TREE, WARRIOR 1, 2, AND 3). THE RESULTS REVEALED SIGNIFICANT DIFFERENCES IN HIP, KNEE, AND ANKLE JMOFS AND VARYING DEGREES OF MUSCLE ACTIVATION AMONG THE POSES. AMONG THESE POSES, RECTUS FEMORIS MUSCLE ACTIVATION DURING THE CHAIR POSE WAS THE HIGHEST, WARRIOR 2 PRODUCED THE HIGHEST MUSCLE ACTIVATION IN THE VASTUS LATERALIS OF THE FRONT LIMB, WHILE WARRIOR 1 HAD THE HIGHEST MUSCLE ACTIVATION IN THE VASTUS MEDIALIS OF THE BACK LIMB. THEREFORE, ALL THREE POSES CAN POSSIBLY BE SUGGESTED AS A THERAPEUTIC INTERVENTION FOR QUADRICEPS STRENGTHENING. WARRIOR 1 WAS POSSIBLY SUGGESTED AS A THERAPEUTIC INTERVENTION IN ORDER TO REDUCE EXCESSIVE LATERAL OVERLOAD OF THE PATELLA, BUT THE POSSIBLE ADVERSE EFFECTS OF WARRIOR 2 WITH THE HIGHEST KNEE ADDUCTOR JMOF IN THE BACK LIMB COULD RAISE JOINT REACTION FORCES ACROSS THE MEDIAL CONDYLES. IN SINGLE-LEG BALANCE POSTURES, WARRIOR 3 HAD UNIQUE TRAINING EFFECTS ON THE HAMSTRING, AND IS THEREFORE SUGGESTED AS A PART OF HAMSTRING REHABILITATION EXERCISES. THE TREE POSE INDUCED LOW LOWER-EXTREMITY JMOFS AND A LOW LEVEL OF THIGH MUSCLE ACTIVATIONS WHEN IT WAS PERFORMED BY SENIOR INSTRUCTORS WITH EXCELLENT BALANCE CONTROL; HOWEVER, FOR YOGA BEGINNERS WITH INSUFFICIENT STABILITY, IT WILL BE A USEFUL TRAINING MODE FOR STRENGTHENING THE MUSCLES THAT HELP TO KEEP ONE UPRIGHT. THIS STUDY QUANTIFIED THE PHYSICAL DEMANDS OF YOGA POSES USING BIOMECHANICAL DATA AND ELUCIDATED THE STRUCTURES AND PRINCIPLES UNDERLYING EACH YOGA MOVEMENT. THIS IS CRUCIAL FOR YOGA PRACTITIONERS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
7  322  34 ANKLE MOTION IN COMMON YOGA POSES. BACKGROUND: MOTION OF THE ANKLE IS ESSENTIAL FOR MANY YOGA POSES. AN UNDERSTANDING OF RANGE OF ANKLE MOTION DURING TYPICAL YOGA POSES MAY HELP THE CLINICIAN TO UNDERSTAND EXPECTED OUTCOMES OF PATIENTS WHEN RETURNING FROM ANKLE SURGERY OR INJURY TO YOGA. METHODS: THE BIOMECHANICS OF TWENTY HEALTHY ACTIVE YOGIS WERE COLLECTED DURING SEVEN YOGA POSES THAT ARE COMMON WITHIN THEIR PRACTICES. MOTION CAPTURE AND FORCE PLATES WERE USED TO ASSESS THE RANGE OF MOTION AND JOINT MOMENTS OF THE ANKLE FOR EACH POSE. RESULTS: ALL POSES RESULTED IN PLANTARFLEXION AND EXTERNAL ROTATION MOMENTS AT THE ANKLE JOINTS. JOINT LOADING WAS HIGHEST IN SINGLE LEG POSES. THE ARC OF MOTION USED BY THE STUDY PARTICIPANTS IN THE POSES WAS 29 DEGREES OF SAGITTAL MOTION, 20 DEGREES OF FRONTAL MOTION AND 35 DEGREES OF TRANSVERSE MOTION. DISCUSSION: ANKLE MOTION WAS EVALUATED WHEN HEALTHY YOGIS PERFORM STANDARD POSES. THESE RESULTS MAY HELP IN DISCUSSION WITH PATIENTS REGARDING EXPECTED OUTCOMES AFTER ANKLE INJURY OR SURGERY.	2019	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
8  971  28 EFFECTS OF AN INTEGRATED APPROACH OF HATHA YOGA THERAPY ON FUNCTIONAL DISABILITY, PAIN, AND FLEXIBILITY IN OSTEOARTHRITIS OF THE KNEE JOINT: A RANDOMIZED CONTROLLED STUDY. OBJECTIVES: THE STUDY OBJECTIVES WERE TO EVALUATE THE EFFICACY OF INTEGRATING HATHA YOGA THERAPY WITH THERAPEUTIC EXERCISES FOR OSTEOARTHRITIS (OA) OF THE KNEE JOINTS. DESIGN: THIS WAS A PROSPECTIVE, RANDOMIZED, ACTIVE CONTROLLED TRIAL. TWO HUNDRED AND FIFTY (250) PARTICIPANTS WHO HAD OA KNEES AND WHO WERE BETWEEN 35 AND 80 YEARS (YOGA 59.56+/-9.54) AND (CONTROL 59.42+/-10.66) FROM THE OUTPATIENT DEPARTMENT OF EBNEZAR ORTHOPEDIC CENTER, BENGALURU, WERE RANDOMLY ASSIGNED TO RECEIVE HATHA YOGA THERAPY OR THERAPEUTIC EXERCISES AFTER TRANSCUTANEOUS ELECTRICAL STIMULATION AND ULTRASOUND TREATMENT (20 MINUTES PER DAY). BOTH OF THE GROUPS PRACTICED SUPERVISED INTERVENTIONS (40 MINUTES PER DAY) FOR 3 MONTHS. ONE HUNDRED AND EIGHTEEN (118) (YOGA) AND 117 (CONTROL) SUBJECTS WERE AVAILABLE FOR THE FINAL ANALYSIS. RESULTS: THERE WERE SIGNIFICANT DIFFERENCES WITHIN (WILCOXON'S, P<0.001) AND BETWEEN THE GROUPS (MANN-WHITNEY U, P<0.001) ON ALL THE VARIABLES, WITH BETTER IMPROVEMENTS IN THE YOGA THAN THE CONTROL GROUPS. WALKING PAIN IN THE YOGA (37.3%, 64.9%) AND CONTROL (24.9%, 42%), KNEE DISABILITY IN THE YOGA (59.7%, 83%) AND CONTROL (32.7%, 53.6%), RANGE OF KNEE FLEXION IN YOGA (12.7%, 26.5% RIGHT, 13.5%, 28% LEFT) AND CONTROL (6.9%, 13.3% RIGHT, 5.6%, 11.5% LEFT), JOINT TENDERNESS IN YOGA (52.3%, 86.1%) AND CONTROL (28%, 57.1%), SWELLING IN YOGA (55.4%, 85.9%) AND CONTROL (32.1%, 60%), CREPITUS IN YOGA (44.0%, 79.9%) AND CONTROL (27.0%, 47.8%) AND WALKING TIME IN YOGA (26.6%, 52.8%) AND CONTROL (9.3%, 21.6%), ALL IMPROVED MORE IN THE YOGA THAN THE CONTROL GROUPS ON THE 15TH AND 90TH DAY, RESPECTIVELY. CONCLUSIONS: AN INTEGRATED APPROACH OF HATHA YOGA THERAPY IS BETTER THAN THERAPEUTIC EXERCISES AS AN ADJUNCT TO TRANSCUTANEOUS ELECTRICAL STIMULATION AND ULTRASOUND TREATMENT IN IMPROVING WALKING PAIN, RANGE OF KNEE FLEXION, WALKING TIME, TENDERNESS, SWELLING, CREPITUS, AND KNEE DISABILITY IN PATIENTS WITH OA KNEES.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
9 1743  27 PHYSICAL-PERFORMANCE OUTCOMES AND BIOMECHANICAL CORRELATES FROM THE 32-WEEK YOGA EMPOWERS SENIORS STUDY. BACKGROUND. YOGA EMPOWERS SENIORS STUDY (YESS) QUANTIFIED PHYSICAL DEMANDS ASSOCIATED WITH YOGA PERFORMANCE USING BIOMECHANICAL METHODS. THIS STUDY EVALUATED THE EFFICACY OF THE PROGRAM ON PHYSICAL FUNCTION OUTCOMES. METHODS. TWENTY COMMUNITY-DWELLING OLDER ADULTS AGED 70.7 +/- 3.8 YEARS ATTENDED BIWEEKLY 60-MINUTE HATHA YOGA CLASSES FOR 32 WEEKS. FOUR DOMAINS OF THE PHYSICAL MEASUREMENTS INCLUDING (1) FUNCTIONAL PERFORMANCE, (2) FLEXIBILITY, (3) MUSCLE STRENGTH, AND (4) BALANCE WERE TAKEN AT THE BASELINE, 16-WEEK AND 32-WEEK TIME POINTS. REPEATED-MEASURES ANOVA OMNIBUS TESTS AND TUKEY'S POST HOC TESTS WERE EMPLOYED TO EXAMINE THE DIFFERENCES IN EACH OUTCOME VARIABLE ACROSS THE 3 TIME POINTS. RESULTS. IMPROVED TIMED CHAIR STANDS (P < 0.01), 8-FOOT UP AND GO (P < 0.05), 2-MIN STEP TEST (P < 0.05), AND VERTICAL REACH (P = 0.05) PERFORMANCE WERE EVIDENT. ISOMETRIC KNEE FLEXOR STRENGTH (P < 0.05) AND REPETITIONS OF THE HEEL RISE TEST (P < 0.001) ALSO INCREASED FOLLOWING THE 32-WEEK INTERVENTION. BOTH FLEXIBILITY AND BALANCE PERFORMANCE REMAINED UNCHANGED. CONCLUSIONS. SIGNIFICANT IMPROVEMENTS IN PHYSICAL FUNCTION AND MUSCLE-SPECIFIC LOWER-EXTREMITY STRENGTH OCCUR WITH THE REGULAR PRACTICE OF A MODIFIED HATHA YOGA PROGRAM DESIGNED FOR SENIORS. THESE ADAPTATIONS CORRESPONDED WITH THE PREVIOUSLY REPORTED BIOMECHANICAL DEMANDS OF THE POSES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
10 1573  30 MANAGING KNEE OSTEOARTHRITIS WITH YOGA OR AEROBIC/STRENGTHENING EXERCISE PROGRAMS IN OLDER ADULTS: A PILOT RANDOMIZED CONTROLLED TRIAL. ALTHOUGH EXERCISE IS OFTEN RECOMMENDED FOR MANAGING OSTEOARTHRITIS (OA), LIMITED EVIDENCE-BASED EXERCISE OPTIONS ARE AVAILABLE FOR OLDER ADULTS WITH OA. THIS STUDY COMPARED THE EFFECTS OF HATHA YOGA (HY) AND AEROBIC/STRENGTHENING EXERCISES (ASE) ON KNEE OA. RANDOMIZED CONTROLLED TRIAL WITH THREE ARMS DESIGN WAS USED: HY, ASE, AND EDUCATION CONTROL. BOTH HY AND ASE GROUPS INVOLVED 8 WEEKLY 45-MIN GROUP CLASSES WITH 2-4 DAYS/WEEK HOME PRACTICE SESSIONS. CONTROL GROUP RECEIVED OA EDUCATION BROCHURES AND WEEKLY PHONE CALLS FROM STUDY STAFF. STANDARDIZED INSTRUMENTS WERE USED TO MEASURE OA SYMPTOMS, PHYSICAL FUNCTION, MOOD, SPIRITUAL HEALTH, FEAR OF FALLING, AND QUALITY OF LIFE AT BASELINE, 4 AND 8 WEEKS. HY/ASE ADHERENCES WERE ASSESSED WEEKLY USING CLASS ATTENDANCE RECORDS AND HOME PRACTICE VIDEO RECORDINGS. PRIMARY ANALYSIS OF THE DIFFERENCE IN THE CHANGE FROM BASELINE WAS BASED ON INTENT-TO-TREAT AND ADJUSTED FOR BASELINE VALUES. EIGHT-THREE ADULTS WITH SYMPTOMATIC KNEE OA COMPLETED THE STUDY (84% FEMALE; MEAN AGE 71.6 +/- 8.0 YEARS; MEAN BMI 29.0 +/- 7.0 KG/M(2)). RETENTION RATE WAS 82%. COMPARED TO THE ASE GROUP AT 8 WEEKS, PARTICIPANTS IN THE HY GROUP HAD A SIGNIFICANT IMPROVEMENT FROM BASELINE IN PERCEPTION OF OA SYMPTOMS (-9.6 [95% CI -15.3, -4]; P = .001), ANXIETY (-1.4 [95% CI -2.7, -0]; P = .04), AND FEAR OF FALLING (-4.6 [-7.5, -1.7]; P = .002). THERE WERE NO DIFFERENCES IN CLASS/HOME PRACTICE ADHERENCE BETWEEN HY AND ASE. THREE NON-SERIOUS ADVERSE EVENTS WERE REPORTED FROM THE ASE GROUP. BOTH HY AND ASE IMPROVED SYMPTOMS AND FUNCTION BUT HY MAY HAVE SUPERIOR BENEFITS FOR OLDER ADULTS WITH KNEE OA.

11 1741  34 PHYSICAL DEMAND PROFILES OF HATHA YOGA POSTURES PERFORMED BY OLDER ADULTS. UNDERSTANDING THE PHYSICAL DEMANDS PLACED UPON THE MUSCULOSKELETAL SYSTEM BY INDIVIDUAL POSTURES MAY ALLOW EXPERIENCED INSTRUCTORS AND THERAPISTS TO DEVELOP SAFE AND EFFECTIVE YOGA PROGRAMS WHICH REDUCE UNDESIRABLE SIDE EFFECTS. THUS, WE USED BIOMECHANICAL METHODS TO QUANTIFY THE LOWER EXTREMITY JOINT ANGLES, JOINT MOMENTS OF FORCE, AND MUSCLE ACTIVITIES OF 21 HATHA YOGA POSTURES, COMMONLY USED IN SENIOR YOGA PROGRAMS. TWENTY OLDER ADULTS, 70.7 YEARS +/- 3.8 YEARS, PARTICIPATED IN A 32-WK YOGA CLASS (2 D/WK) WHERE THEY LEARNED INTRODUCTORY AND INTERMEDIATE POSTURES (ASANAS). THEY THEN PERFORMED THE ASANAS IN A MOTION ANALYSIS LABORATORY. KINEMATIC, KINETIC, AND ELECTROMYOGRAPHIC DATA WAS COLLECTED OVER THREE SECONDS WHILE THE PARTICIPANTS HELD THE POSES STATICALLY. PROFILES ILLUSTRATING THE POSTURES AND INCLUDING THE BIOMECHANICAL DATA WERE THEN GENERATED FOR EACH ASANA. OUR FINDINGS DEMONSTRATED THAT HATHA YOGA POSTURES ENGENDERED A RANGE OF APPRECIABLE JOINT ANGLES, JMOFS, AND MUSCLE ACTIVITIES ABOUT THE ANKLE, KNEE, AND HIP, AND THAT DEMANDS ASSOCIATED WITH SOME POSTURES AND POSTURE MODIFICATIONS WERE NOT ALWAYS INTUITIVE. THEY ALSO DEMONSTRATED THAT ALL OF THE POSTURES ELICITED APPRECIABLE RECTUS ABDOMINIS ACTIVITY, WHICH WAS UP TO 70% OF THAT INDUCED DURING WALKING.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
12  782  26 EFFECT OF YOGA BASED LIFESTYLE INTERVENTION ON PATIENTS WITH KNEE OSTEOARTHRITIS: A RANDOMIZED CONTROLLED TRIAL. OBJECTIVE: TO INVESTIGATE THE EFFECT OF INTEGRATED APPROACH OF YOGA THERAPY (IAYT) INTERVENTION IN INDIVIDUAL WITH KNEE OSTEOARTHRITIS. DESIGN: RANDOMIZED CONTROLLED CLINCIAL TRAIL. PARTICIPANTS: SIXTY-SIX INDIVIDUAL PREDIAGNOSED WITH KNEE OSTEOARTHRITIS AGED BETWEEN 30 AND 75 YEARS WERE RANDOMIZED INTO TWO GROUPS, I.E., YOGA (N = 31) AND CONTROL (N = 35). YOGA GROUP RECEIVED IAYT INTERVENTION FOR 1 WEEK AT YOGA CENTER OF S-VYASA WHEREAS CONTROL GROUP MAINTAINED THEIR NORMAL LIFESTYLE. OUTCOME MEASURES: THE FALLS EFFICACY SCALE (FES), HANDGRIP STRENGTH TEST (LEFT HAND LHGS AND RIGHT HAND RHGS), TIMED UP AND GO TEST (TUG), SIT-TO-STAND (STS), AND RIGHT & LEFT EXTENSION AND FLEXION WERE MEASURED ON DAY 1 AND DAY 7. RESULTS: THERE WERE A SIGNIFICANT REDUCTION IN TUG (P < 0.001), RIGHT (P < 0.001), AND LEFT FLEXION (P < 0.001) WHEREAS SIGNIFICANT IMPROVEMENTS IN LHGS (P < 0.01), AND RIGHT EXTENSION (P < 0.05) & LEFT EXTENSION (P < 0.001) FROM BASELINE IN YOGA GROUP. CONCLUSION: IAYT PRACTICE SHOWED AN IMPROVEMENT IN TUG, STS, HGS, AND GONIOMETER TEST, WHICH SUGGEST IMPROVED MUSCULAR STRENGTH, FLEXIBILITY, AND FUNCTIONAL MOBILITY.

13  684  30 EFFECT OF AN INTEGRATED APPROACH OF YOGA THERAPY ON QUALITY OF LIFE IN OSTEOARTHRITIS OF THE KNEE JOINT: A RANDOMIZED CONTROL STUDY. AIM: THIS STUDY WAS DESIGNED TO EVALUATE THE EFFICACY OF ADDITION OF INTEGRATED YOGA THERAPY TO THERAPEUTIC EXERCISES IN OSTEOARTHRITIS (OA) OF KNEE JOINTS. MATERIALS AND METHODS: THIS WAS A PROSPECTIVE RANDOMIZED ACTIVE CONTROL TRIAL. A TOTAL OF T PARTICIPANTS WITH OA OF KNEE JOINTS BETWEEN 35 AND 80 YEARS (YOGA, 59.56 +/- 9.54 AND CONTROL, 59.42 +/- 10.66) FROM THE OUTPATIENT DEPARTMENT OF DR. JOHN'S ORTHOPEDIC CENTER, BENGALURU, WERE RANDOMLY ASSIGNED TO RECEIVE YOGA OR PHYSIOTHERAPY EXERCISES AFTER TRANSCUTANEOUS ELECTRICAL STIMULATION AND ULTRASOUND TREATMENT OF THE AFFECTED KNEE JOINTS. BOTH GROUPS PRACTICED SUPERVISED INTERVENTION (40 MIN PER DAY) FOR 2 WEEKS (6 DAYS PER WEEK) WITH FOLLOWUP FOR 3 MONTHS. THE MODULE OF INTEGRATED YOGA CONSISTED OF SHITHILIKARANAVYAYAMA (LOOSENING AND STRENGTHENING), ASANAS, RELAXATION TECHNIQUES, PRANAYAMA, MEDITATION AND DIDACTIC LECTURES ON YAMA, NIYAMA, JNANA YOGA, BHAKTI YOGA, AND KARMA YOGA FOR A HEALTHY LIFESTYLE CHANGE. THE CONTROL GROUP ALSO HAD SUPERVISED PHYSIOTHERAPY EXERCISES. A TOTAL OF 118 (YOGA) AND 117 (CONTROL) WERE AVAILABLE FOR FINAL ANALYSIS. RESULTS: SIGNIFICANT DIFFERENCES WERE OBSERVED WITHIN (P < 0.001, WILCOXON'S) AND BETWEEN GROUPS (P < 0.001, MANN-WHITNEY U-TEST) ON ALL DOMAINS OF THE SHORT FORM-36 (P < 0.004), WITH BETTER RESULTS IN THE YOGA GROUP THAN IN THE CONTROL GROUP, BOTH AT 15(TH) DAY AND 90(TH) DAY. CONCLUSION: AN INTEGRATED APPROACH OF YOGA THERAPY IS BETTER THAN THERAPEUTIC EXERCISES AS AN ADJUNCT TO TRANSCUTANEOUS ELECTRICAL STIMULATION AND ULTRASOUND TREATMENT IN IMPROVING KNEE DISABILITY AND QUALITY OF LIFE IN PATIENTS WITH OA KNEES.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
14  387  25 BENEFITS OF THAI YOGA ON PHYSICAL MOBILITY AND LOWER LIMB MUSCLE STRENGTH IN OVERWEIGHT/OBESE OLDER WOMEN: A RANDOMIZED CONTROLLED PILOT TRIAL. BACKGROUND AND PURPOSE: ALTHOUGH THAI YOGA (TY) IS REPORTED TO IMPROVE HEALTH-RELATED FITNESS FOR THE ELDERLY, NO STUDY HAS YET CARRIED OUT THE EFFECT OF TY PROGRAM ON PHYSICAL MOBILITY AND LOWER-LIMB MUSCLE STRENGTH IN OVERWEIGHT/OBESE OLDER WOMEN. MATERIALS AND METHODS: IN A RANDOMIZED CONTROLLED PILOT DESIGN, TWENTY-TWO SEDENTARY WOMEN WITH A BMI >/= 23 KG/M(2), AGED 62 +/- 1 YEARS WERE RANDOMLY ASSIGNED TO EITHER A TY GROUP FOR 60 MIN, 3 TIMES A WEEK OR TO A "NO EXERCISE" CONTROL (CON) GROUP. SIT AND REACH (SRT), FUNCTIONAL REACH (FRT) AND 30-S CHAIR STAND (CST-30), 8-FOOT UP AND GO (8UGT), 6-MIN WALK (6MWT)) AND LOWER-LIMB MUSCLE STRENGTH WERE MEASURED AT THE BEGINNING, 4, AND 8 WEEKS. RESULTS: AT WEEK 4, A SIGNIFICANT BETWEEN GROUPS WAS OBTAINED IN CST-30, 8UGT, AND 6MWT. AT WEEK 8, FRT, 8UGT, 6MWT AND KNEE FLEXOR AND EXTENSOR MUSCLE STRENGTH WERE IMPROVED IN THE TY OVER THE CON. SIGNIFICANT IMPROVEMENT WAS FOUND IN ALL VARIABLES WITHIN THE TY, BUT NO CHANGE WAS OBSERVED IN THE CON. CONCLUSION: AN 8-WEEK TY PROGRAM APPEARS TO PROVIDE BENEFICIAL IMPROVEMENTS IN PHYSICAL MOBILITY IN OVERWEIGHT/OBESE OLDER WOMEN.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
15  992  23 EFFECTS OF HATHA YOGA PRACTICE ON THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS. TEN HEALTHY, UNTRAINED VOLUNTEERS (NINE FEMALES AND ONE MALE), RANGING IN AGE FROM 18-27 YEARS, WERE STUDIED TO DETERMINE THE EFFECTS OF HATHA YOGA PRACTICE ON THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS, INCLUDING MUSCULAR STRENGTH AND ENDURANCE, FLEXIBILITY, CARDIORESPIRATORY FITNESS, BODY COMPOSITION, AND PULMONARY FUNCTION. SUBJECTS WERE REQUIRED TO ATTEND A MINIMUM OF TWO YOGA CLASSES PER WEEK FOR A TOTAL OF 8 WEEKS. EACH YOGA SESSION CONSISTED OF 10 MINUTES OF PRANAYAMAS (BREATH-CONTROL EXERCISES), 15 MINUTES OF DYNAMIC WARM-UP EXERCISES, 50 MINUTES OF ASANAS (YOGA POSTURES), AND 10 MINUTES OF SUPINE RELAXATION IN SAVASANA (CORPSE POSE). THE SUBJECTS WERE EVALUATED BEFORE AND AFTER THE 8-WEEK TRAINING PROGRAM. ISOKINETIC MUSCULAR STRENGTH FOR ELBOW EXTENSION, ELBOW FLEXION, AND KNEE EXTENSION INCREASED BY 31%, 19%, AND 28% (P<0.05), RESPECTIVELY, WHEREAS ISOMETRIC MUSCULAR ENDURANCE FOR KNEE FLEXION INCREASED 57% (P<0.01). ANKLE FLEXIBILITY, SHOULDER ELEVATION, TRUNK EXTENSION, AND TRUNK FLEXION INCREASED BY 13% (P<0.01), 155% (P<0.001), 188% (P<0.001), AND 14% (P<0.05), RESPECTIVELY. ABSOLUTE AND RELATIVE MAXIMAL OXYGEN UPTAKE INCREASED BY 7% AND 6%, RESPECTIVELY (P<0.01). THESE FINDINGS INDICATE THAT REGULAR HATHA YOGA PRACTICE CAN ELICIT IMPROVEMENTS IN THE HEALTH-RELATED ASPECTS OF PHYSICAL FITNESS.

16  275  22 ADDITIONAL EFFECT OF IYENGAR YOGA AND EMG BIOFEEDBACK ON PAIN AND FUNCTIONAL DISABILITY IN CHRONIC UNILATERAL KNEE OSTEOARTHRITIS. BACKGROUND: THERE ARE LIMITED DATA ABOUT IYENGAR YOGA AND EMG BIOFEEDBACK IN KNEE OA, ALTHOUGH THE EFFICACY OF EMG BIOFEEDBACK IN THE REHABILITATION OF PATIENTS WITH QUADRICEPS MUSCLE WEAKNESS SECONDARY TO IMMOBILIZATION, CONTRACTURE, AND JOINT SURGERY HAS BEEN WELL ESTABLISHED. MATERIALS AND METHODS: THIRTY SUBJECTS WHO HAVE FULFILLED INCLUSION AND EXCLUSION CRITERIA WERE SELECTED AND DIVIDED INTO TWO GROUPS (GROUP A AND B). BOTH THE GROUPS WERE TREATED WITH EMG BIOFEEDBACK, KNEE MUSCLE STRENGTHENING EXERCISES, AND TENS. GROUP A RECEIVED ADDITIONALLY IYENGAR YOGA FOR 8 WEEKS. BOTH GROUPS WERE EVALUATED BY VISUAL ANALOG SCALE AND MODIFIED WOMAC-WESTERN ONTARIO MCMASTER UNIVERSITIES SCALE. RESULTS: PATIENTS IN BOTH GROUPS EXPERIENCED SIGNIFICANT REDUCTION IN PAIN AND IMPROVEMENT IN FUNCTIONAL ABILITY. IN VAS SCALE GROUP A SHOWED REDUCTION OF 56.83% (P = 0.001) WHEN COMPARED WITH GROUP B 38.15% (P </= 0.001). IN MODIFIED WOMAC SCALE, GROUP A SHOWED REDUCTION OF 59.21% (P = 0.001) WHEN COMPARED WITH GROUP B 34.08% (P = 0.001). CONCLUSION: ADDING IYENGAR YOGA ALONG WITH CONVENTIONAL THERAPY PROVIDES BETTER RESULTS IN CHRONIC UNILATERAL KNEE OSTEOARTHRITIS IN TERMS OF PAIN AND FUNCTIONAL DISABILITY.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
17 2590  29 YOGA FOR MANAGING KNEE OSTEOARTHRITIS IN OLDER WOMEN: A PILOT RANDOMIZED CONTROLLED TRIAL. BACKGROUND: OSTEOARTHRITIS (OA) IS A COMMON PROBLEM IN OLDER WOMEN THAT IS ASSOCIATED WITH PAIN AND DISABILITIES. ALTHOUGH YOGA IS RECOMMENDED AS AN EXERCISE INTERVENTION TO MANAGE ARTHRITIS, THERE IS LIMITED EVIDENCE DOCUMENTING ITS EFFECTIVENESS, WITH LITTLE KNOWN ABOUT ITS LONG TERM BENEFITS. THIS STUDY'S AIMS WERE TO ASSESS THE FEASIBILITY AND POTENTIAL EFFICACY OF A HATHA YOGA EXERCISE PROGRAM IN MANAGING OA-RELATED SYMPTOMS IN OLDER WOMEN WITH KNEE OA. METHODS: ELIGIBLE PARTICIPANTS (N=36; MEAN AGE 72 YEARS) WERE RANDOMLY ASSIGNED TO 8-WEEK YOGA PROGRAM INVOLVING GROUP AND HOME-BASED SESSIONS OR WAIT-LIST CONTROL. THE YOGA INTERVENTION PROGRAM WAS DEVELOPED BY A GROUP OF YOGA EXPERTS (N=5). THE PRIMARY OUTCOME WAS THE WESTERN ONTARIO AND MCMASTER UNIVERSITIES OSTEOARTHRITIS INDEX (WOMAC) TOTAL SCORE THAT MEASURES KNEE OA PAIN, STIFFNESS, AND FUNCTION AT 8 WEEKS. THE SECONDARY OUTCOMES, PHYSICAL FUNCTION OF THE LOWER EXTREMITIES, BODY MASS INDEX (BMI), QUALITY OF SLEEP (QOS), AND QUALITY OF LIFE (QOL), WERE MEASURED USING WEIGHT, HEIGHT, THE SHORT PHYSICAL PERFORMANCE BATTERY (SPPB), THE PITTSBURGH SLEEP QUALITY INDEX (PSQI), THE CANTRIL SELF-ANCHORING LADDER, AND THE SF12V2 HEALTH SURVEY. DATA WERE COLLECTED AT BASELINE, 4 WEEKS AND 8 WEEKS, AND 20 WEEKS. RESULTS: THE RECRUITMENT TARGET WAS MET, WITH STUDY RETENTION AT 95%. BASED ON ANCOVAS, PARTICIPANTS IN THE TREATMENT GROUP EXHIBITED SIGNIFICANTLY GREATER IMPROVEMENT IN WOMAC PAIN (ADJUSTED MEANS [SE]) (8.3 [.67], 5.8 [.67]; P=.01), STIFFNESS (4.7 [.28], 3.4 [.28]; P=.002) AND SPPB (REPEATED CHAIR STANDS) (2.0 [.23], 2.8 [.23]; P=.03) AT 8 WEEKS. SIGNIFICANT TREATMENT AND TIME EFFECTS WERE SEEN IN WOMAC PAIN (7.0 [.46], 5.4 [.54]; P=.03), FUNCTION (24.5 [1.8], 19.9 [1.6]; P=.01) AND TOTAL SCORES (35.4 [2.3], 28.6 [2.1]; P=.01) FROM 4 TO 20 WEEKS. SLEEP DISTURBANCE WAS IMPROVED BUT THE PSQI TOTAL SCORE DECLINED SIGNIFICANTLY AT 20 WEEKS. CHANGES IN BMI AND QOL WERE NOT SIGNIFICANT. NO YOGA RELATED ADVERSE EVENTS WERE OBSERVED. CONCLUSIONS: A WEEKLY YOGA PROGRAM WITH HOME PRACTICE IS FEASIBLE, ACCEPTABLE, AND SAFE FOR OLDER WOMEN WITH KNEE OA, AND SHOWS THERAPEUTIC BENEFITS.

18 2083  26 THE EFFECT OF IYENGAR YOGA AND STRENGTHENING EXERCISES FOR PEOPLE LIVING WITH OSTEOARTHRITIS OF THE KNEE: A CASE SERIES. THIS CASE SERIES DESCRIBES THE IMPACT OF VARIOUS FORMS OF EXERCISE ON SYMPTOMS ASSOCIATED WITH OSTEOARTHRITIS OF THE KNEE. A GROUP OF 15 WOMEN AND MEN PERFORMED ONE OF THE FOLLOWING: TRADITIONAL STRETCHING AND STRENGTHENING EXERCISES, IYENGAR YOGA, OR NO STRUCTURED GROUP EXERCISE. LOW BACK AND HAMSTRING FLEXIBILITY AND QUADRICEPS STRENGTH AND FUNCTION WERE MONITORED BEFORE AND AFTER THE PROGRAM. THE WESTERN ONTARIO AND MCMASTER UNIVERSITIES OSTEOARTHRITIS INDEX (WOMAC) WAS USED TO ASSESS SUBJECTIVE CHANGE AFTER THE SIX-WEEK INTERVENTION PERIOD. A GLOBAL ASSESSMENT QUESTIONNAIRE WAS ALSO COMPLETED BY EACH PARTICIPANT AND EACH INSTRUCTOR AT THE EXIT SESSIONS TO MEASURE PERCEIVED CHANGES IN IMPROVEMENTS SINCE THE INITIATION OF THE INTERVENTION. THIS STUDY FOUND FUNCTIONAL CHANGES AND IMPROVEMENT IN QUALITY OF LIFE IN TRADITIONAL EXERCISE AND A YOGA BASED APPROACH THAT SHOULD ENCOURAGE FURTHER COMPREHENSIVE AND CAREFULLY DESIGNED STUDIES OF YOGA IN OSTEOARTHRITIS.	2006	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     
19  983  27 EFFECTS OF HATA YOGA ON KNEE OSTEOARTHRITIS. BACKGROUND: THE PURPOSE OF THIS RESEARCH WAS TO STUDY THE EFFECTS OF 8 WEEKS OF HATA YOGA EXERCISES ON WOMEN WITH KNEE OSTEOARTHRITIS. STUDIES ABOUT EFFECTS OF YOGA ON DIFFERENT CHRONIC DISEASES SHOW THAT THESE EXERCISES HAVE POSITIVE EFFECTS ON CHRONIC DISEASES. AS KNEE OSTEOARTHRITIS IS VERY COMMON AMONG MIDDLE AGE WOMEN WE DECIDED TO MEASURE EFFECTIVENESS OF THESE EXERCISES ON KNEE OSTEOARTHRITIS. METHODS: SAMPLE INCLUDED 30 WOMEN WITH KNEE OSTEOARTHRITIS WHO VOLUNTARILY PARTICIPATED IN THIS SEMI-EXPERIMENTAL STUDY AND WERE DIVIDED INTO A CONTROL GROUP (15) AND A YOGA GROUP (15). THE YOGA GROUP RECEIVED 60 MINUTES SESSIONS OF HATA YOGA, 3 TIMES A WEEK AND FOR 8 WEEKS. PAIN, SYMPTOMS, DAILY ACTIVITIES, SPORTS AND SPARE-TIME ACTIVITIES, AND QUALITY OF LIFE WERE RESPECTIVELY MEASURED BY VISUAL ANALOG SCALE (VAS) AND KNEE INJURY AND OSTEOARTHRITIS OUTCOME SCALE (KOOS) QUESTIONNAIRE. THE ANALYSIS OF VARIANCE (ANOVA) METHOD FOR REPETITIVE DATA WAS USED TO ANALYZE THE RESULTS (P = 0.05). RESULTS: FINDINGS SHOWED THAT PAIN AND SYMPTOMS WERE SIGNIFICANTLY DECREASED AND SCORES OF DAILY ACTIVITIES, SPORTS, SPARE-TIME ACTIVITIES, AND QUALITY OF LIFE WERE SIGNIFICANTLY INCREASED IN THE YOGA GROUP. CONCLUSIONS: IT SEEMS THAT YOGA CAN BE USED AS A CONSERVATIVE TREATMENT BESIDES USUAL TREATMENTS AND MEDICATIONS TO IMPROVE THE CONDITION OF PEOPLE WITH OSTEOARTHRITIS.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
20 2826  25 YOGA VERSUS MASSAGE IN THE TREATMENT OF AROMATASE INHIBITOR-ASSOCIATED KNEE JOINT PAIN IN BREAST CANCER SURVIVORS: A RANDOMIZED CONTROLLED TRIAL. AROMATASE INHIBITORS (AIS) ARE STANDARD ADJUVANT THERAPY FOR POSTMENOPAUSAL WOMEN WITH OESTROGEN RECEPTOR-POSITIVE, EARLY-STAGE, AND METASTATIC BREAST CANCER. ALTHOUGH EFFECTIVE, THE RISK OF FALLS DUE TO AI-ASSOCIATED KNEE JOINT PAIN SIGNIFICANTLY INCREASED. THE AIM OF THIS STUDY WAS TO EVALUATE THE THERAPEUTIC EFFECTS OF YOGA AND MASSAGE ON AI-ASSOCIATED KNEE JOINT PAIN. BREAST CANCER SURVIVORS WERE RANDOMLY ASSIGNED TO A 6-WEEK YOGA INTERVENTION-2-WEEK REST-6-WEEK MASSAGE EXPOSURE (YOGA FIRST, N = 30) OR A 6-WEEK MASSAGE INTERVENTION-2-WEEK REST-6-WEEK YOGA EXPOSURE (MASSAGE FIRST, N = 30). EVALUATIONS OF THE TREATMENT EFFICACY WERE MADE AT BASELINE, POST-INTERVENTION, AND POST-EXPOSURE USING THE WESTERN ONTARIO AND MCMASTER UNIVERSITIES OSTEOARTHRITIS INDEX (WOMAC) SCALE, PLASMA CYTOKINE LEVELS, AND CHANGES IN MERIDIAN ENERGY. THE RESULTS SHOWED THAT YOGA, SUPERIOR TO MASSAGE INTERVENTION, SIGNIFICANTLY REDUCED AI-ASSOCIATED KNEE JOINT PAIN, AS DEMONSTRATED BY THE WOMAC PAIN SCORE. THE YOGA INTERVENTION IMPROVEMENTS WERE ALSO ASSOCIATED WITH CHANGES IN PLASMA CYTOKINE LEVELS AND MERIDIAN ENERGY CHANGES. IN CONCLUSION, THIS STUDY PROVIDES SCIENTIFIC EVIDENCE THAT YOGA WAS MORE EFFECTIVE THAN MASSAGE FOR REDUCING AI-ASSOCIATED KNEE JOINT PAIN. MERIDIAN ENERGY CHANGES MAY PROVIDE ANOTHER SCIENTIFIC, OBJECTIVE, NON-INVASIVE WAY TO MONITOR THE THERAPEUTIC EFFECTS OF YOGA AND INVESTIGATE ANOTHER ALTERNATIVE, COMPLEMENTARY MEDICINE.	2021
