1 1359 139 IMMEDIATE EFFECTS OF OM CHANTING ON HEART RATE VARIABILITY MEASURES COMPARED BETWEEN EXPERIENCED AND INEXPERIENCED YOGA PRACTITIONERS. BACKGROUND: CHANTING "OM" IS A FORM OF MEDITATION THAT HAS NUMEROUS HEALTH BENEFITS. HOWEVER, THE NEUROPHYSIOLOGICAL MECHANISMS UNDERPINNING ITS EFFECT ARE SURPRISINGLY SCARCE. THE PRESENT STUDY AIMED TO INVESTIGATE THE EFFECT OF OM CHANTING ON AUTONOMIC MODULATION, USING HEART RATE VARIABILITY (HRV), ON EXPERIENCED YOGA PRACTITIONERS AND YOGA NAIVE PERSONS. METHODS: THIS PROSPECTIVE STUDY INCLUDED 19 YOGA PRACTITIONERS (9 FEMALES AND 10 MALES; GROUP MEAN AGE +/- STANDARD DEVIATION [SD]; 25.9 +/- 3.2 YEARS) AND 17 YOGA NAIVE PERSONS (8 FEMALES AND 9 MALES; GROUP MEAN AGE +/- SD; 24.8 +/- 3.6 YEARS) OF BOTH SEXES AND SIMILAR AGE RANGE. BOTH THE GROUPS WERE ASSESSED FOR HRV INDICES (TIME AND FREQUENCY DOMAIN MEASURES) BEFORE AND AFTER LOUD OM CHANTING FOR 5 MIN. RESULTS: BASELINE COMPARISON USING MANN-WHITNEY U TEST BETWEEN GROUPS SHOWED YOGA PRACTITIONERS HAD SIGNIFICANTLY INCREASED HIGH FREQUENCY (HF) POWER (P < 0.029) THAN NONYOGA PRACTITIONERS, SIGNIFYING A STATE OF TRANQUILITY BEFORE THE CHANTING OF OM. AFTER 5 MIN OF LOUD CHANTING OF OM, A COMPARISON BETWEEN GROUPS ASSESSED USING WILCOXON SIGNED RANKS TEST REVEALED: HF POWER, A COMPONENT OF THE PARASYMPATHETIC NERVOUS SYSTEM, WAS FURTHER AMPLIFIED WITH A SIGNIFICANTLY INCREASE (P < 0.001) IN THE YOGA PRACTITIONERS GROUP COMPARED TO NONYOGA PRACTITIONERS. FURTHERMORE, THIS INCREASE IN HF POWER WAS POSITIVELY CORRELATED WITH THE YEARS OF EXPERIENCE IN YOGA. CONCLUSION: THE PRESENT STUDY SHOWED THAT A BRIEF CHANTING OF OM (5 MIN) MIGHT ENHANCE PARASYMPATHETIC NERVOUS SYSTEM ACTIVITY, PROMOTE RELAXATION, AND PROVIDE CALMNESS. FURTHER, THIS EXPERIENCE MAY BE ACHIEVED EFFECTIVELY IN INDIVIDUALS EXPERIENCED IN YOGA THAN NONYOGA PRACTITIONERS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
2  703  38 EFFECT OF INTEGRAL YOGA ON PSYCHOLOGICAL AND HEALTH VARIABLES AND THEIR CORRELATIONS. OBJECTIVE: CERTAIN PSYCHOLOGICAL AND HEALTH VARIABLES ARE COMMONLY MEASURED IN INDIA. THIS STUDY EVALUATES THE EFFECTS OF INTEGRAL YOGA PRACTICES ON THESE VARIABLES AND ALSO THE CONSISTENCY OF CORRELATIONS OBSERVED BETWEEN THEM. MATERIALS AND METHODS: THE STUDY WAS A PRE-POST INTERVENTION STUDY. THE VARIABLES WERE MEASURED AT THE BEGINNING AND THE END OF A ONE-MONTH YOGA COURSE. THERE WAS NO CONTROL GROUP.THE STUDY WAS CARRIED OUT AT SWAMI VIVEKANANDA YOGA ANUSANDHANA SAMSTHANA (S-VYASA) UNIVERSITY, IN ITS RURAL CAMPUS SOUTH OF BANGALORE. BASED ON HEALTH CRITERIA, 108 SUBJECTS WERE SELECTED OUT OF 198 VOLUNTEERS TO FORM THE EXPERIMENTAL YOGA GROUP. AGES RANGED FROM 17 TO 63 YEARS. THE YOGASANAS (POSTURES), PRANAYAMA (BREATHING EXERCISES), RELAXATION TECHNIQUES, MEDITATION, CHANTING AND LECTURES WERE THE COMPONENTS OF YOGA INTERVENTION. THE VARIABLES MEASURED WERE SUSTAINED ATTENTION, EMOTIONAL INTELLIGENCE - EQ, GENERAL HEALTH - GHQ, GUNA PERSONALITY - SATTVA, RAJAS AND TAMAS. RESULTS: SIGNIFICANT PRE-POST CHANGES WERE FOUND IN ALL VARIABLES. SIGNIFICANT CORRELATIONS WERE FOUND BETWEEN THE FOLLOWING PAIRS: THE TWO SUSTAINED ATTENTION VARIABLES; EMOTIONAL INTELLIGENCE AND GENERAL HEALTH; GHQ AND TAMAS; SATTVA AND TAMAS; AND RAJAS AND TAMAS. CONCLUSION: THE STUDY SHOWS THAT THERE WERE SIGNIFICANT CHANGES IN ALL VARIABLES (P< 0.001) EXCEPT IN SATTVA. IT ALSO CONFIRMS THAT EQ AND GENERAL HEALTH VARIABLES CORRELATE SIGNIFICANTLY WITH EACH OTHER AND NEGATIVELY WITH TAMAS. EQ AND TAMAS FORM POSITIVE AND NEGATIVE PREDICTORS OF HEALTH RESPECTIVELY. SATTVA CORRELATES POSITIVELY WITH EQ SUGGESTING THAT A SATTVIC PERSONALITY INDICATES BETTER SELF-CONTROL. THIS SUGGESTS THAT, BY IMPROVING GUNA PERSONALITY, LONG-TERM YOGA PRACTICE MAY STABILIZE EQ.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                   
3 1975  39 SINGLE SESSION OF INTEGRATED "SILVER YOGA" PROGRAM IMPROVES CARDIOVASCULAR PARAMETERS IN SENIOR CITIZENS. AIM AND OBJECTIVE: THIS PILOT STUDY WAS CARRIED OUT TO DETERMINE CARDIOVASCULAR EFFECTS OF A SINGLE SESSION OF AN INTEGRATED "SILVER YOGA" PROGRAM IN SENIOR CITIZENS OF SERENE PELICAN TOWNSHIP, PONDICHERRY. MATERIALS AND METHODS: HEART RATE (HR) AND BLOOD PRESSURE (BP) MEASUREMENTS WERE RECORDED IN 124 SENIOR CITIZENS (75 FEMALE, 49 MALE) WITH MEAN AGE OF 67.19 +/- 10.61 YEAR WHO ATTENDED AN INTEGRATED "SILVER YOGA" PROGRAM AT CENTRE FOR YOGA THERAPY, EDUCATION AND RESEARCH FROM AUGUST TO OCTOBER 2014. PARTICIPANTS PRACTICED THE PROTOCOL THAT WAS SPECIALLY DESIGNED FOR SENIOR CITIZENS, KEEPING IN MIND THEIR HEALTH STATUS AND PHYSICAL LIMITATIONS. THIS INCLUDED SIMPLE WARM-UPS (JATHIS), BREATH BODY MOVEMENT COORDINATION PRACTICES (KRIYAS), STATIC STRETCHING POSTURES (ASANAS), BREATHING TECHNIQUES (PRANAYAMAS), RELAXATION AND SIMPLE CHANTING. NON-INVASIVE BP APPARATUS WAS USED TO RECORD THE HR, SYSTOLIC (SP) AND DIASTOLIC PRESSURE (DP) BEFORE AND AFTER THE 60 MIN SESSIONS. PULSE PRESSURE (PP), MEAN PRESSURE (MP), RATE-PRESSURE PRODUCT (RPP) AND DOUBLE PRODUCT (DOP) INDICES WERE DERIVED FROM THE RECORDED PARAMETERS. STUDENT'S PAIRED T-TEST WAS USED TO COMPARE DATA THAT PASSED NORMALITY TESTING BY KOLMOGOROV-SMIRNOV TEST AND WILCOXON MATCHED-PAIRS SIGNED-RANKS TEST FOR THOSE THAT DID NOT. P < 0.05 WERE ACCEPTED AS INDICATING SIGNIFICANT DIFFERENCES FOR PRE-POST COMPARISONS. RESULTS: ALL PARAMETERS WITNESSED A REDUCTION FOLLOWING THE SINGLE SESSION. THIS WAS STATISTICALLY MORE SIGNIFICANT (P < 0. 0001) IN HR, RPP AND DOP WHILE IT WAS ALSO SIGNIFICANT (P < 0.01 AND P < 0.05) IN SP AND PP, RESPECTIVELY. THE DECREASE IN MP JUST MISSED SIGNIFICANCE (P = 0.054) WHILE IT WAS NOT SIGNIFICANT IN DP. CONCLUSION: THERE IS A HEALTHY REDUCTION IN HR, BP AND DERIVED CARDIOVASCULAR INDICES FOLLOWING A SINGLE YOGA SESSION IN GERIATRIC SUBJECTS. THESE CHANGES MAY BE ATTRIBUTED TO ENHANCED HARMONY OF CARDIAC AUTONOMIC FUNCTION AS A RESULT OF COORDINATED BREATH-BODY WORK AND MIND-BODY RELAXATION DUE TO AN INTEGRATED "SILVER YOGA" PROGRAM.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
4  163  42 A RANDOMIZED CONTROL TRIAL OF THE EFFECT OF YOGA ON GUNAS (PERSONALITY) AND HEALTH IN NORMAL HEALTHY VOLUNTEERS. OBJECTIVE: TO STUDY THE EFFICACY OF YOGA ON GUNA (YOGIC PERSONALITY MEASURE) AND GENERAL HEALTH IN NORMAL ADULTS. METHODS: OF THE 1228 PERSONS WHO ATTENDED INTRODUCTORY LECTURES, 226 SUBJECTS AGED 18-71 YEARS, OF BOTH SEXES, WHO SATISFIED THE INCLUSION AND EXCLUSION CRITERIA AND WHO CONSENTED TO PARTICIPATE IN THE STUDY WERE RANDOMLY ALLOCATED INTO TWO GROUPS. THE YOGA(Y) GROUP PRACTISED AN INTEGRATED YOGA MODULE THAT INCLUDED ASANAS, PRANAYAMA, MEDITATION, NOTIONAL CORRECTION AND DEVOTIONAL SESSIONS. THE CONTROL GROUP PRACTISED MILD TO MODERATE PHYSICAL EXERCISES (PE). BOTH GROUPS HAD SUPERVISED PRACTICE SESSIONS (BY TRAINED EXPERTS) FOR ONE HOUR DAILY, SIX DAYS A WEEK FOR EIGHT WEEKS. GUNA (YOGIC PERSONALITY) WAS ASSESSED BEFORE AND AFTER EIGHT WEEKS USING THE SELF-ADMINISTERED VEDIC PERSONALITY INVENTORY (VPI) WHICH ASSESSES SATTVA (GENTLE AND CONTROLLED), RAJAS (VIOLENT AND UNCONTROLLED) AND TAMAS (DULL AND UNCONTROLLED). THE GENERAL HEALTH STATUS (TOTAL HEALTH), WHICH INCLUDES FOUR DOMAINS NAMELY SOMATIC SYMPTOMS (SS), ANXIETY AND INSOMNIA (AI), SOCIAL DYSFUNCTION (SF) AND SEVERE DEPRESSION (SP), WAS ASSESSED USING A GENERAL HEALTH QUESTIONNAIRE (GHQ). RESULTS: BASELINE SCORES FOR ALL THE DOMAINS FOR BOTH THE GROUPS DID NOT DIFFER SIGNIFICANTLY (P > 0.05, INDEPENDENT SAMPLES T TEST). SATTVA SHOWED A SIGNIFICANT DIFFERENCE WITHIN THE GROUPS AND THE EFFECT SIZE WAS MORE IN THE Y THAN IN THE PE GROUP. RAJAS SHOWED A SIGNIFICANT DECREASE WITHIN AND BETWEEN THE GROUPS WITH A HIGHER EFFECT SIZE IN THE PE GROUP. TAMAS SHOWED SIGNIFICANT REDUCTION WITHIN THE PE GROUP ONLY. THE GHQ REVEALED THAT THERE WAS SIGNIFICANT DECREASE IN SS, AI, SF AND SP IN BOTH Y AND PE GROUPS (WILCOXCON SINGED RANK T TEST). SS SHOWED A SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS (MANN WHITNEY U TEST). CONCLUSIONS: THERE WAS AN IMPROVEMENT IN SATTVA IN BOTH THE YOGA AND CONTROL GROUPS WITH A TREND OF HIGHER EFFECT SIZE IN YOGA; RAJAS REDUCED IN BOTH BUT SIGNIFICANTLY BETTER IN PE THAN IN YOGA AND TAMAS REDUCED IN PE. THE GENERAL HEALTH STATUS IMPROVED IN BOTH THE YOGA AND CONTROL GROUPS.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
5  724  44 EFFECT OF LAUGHTER YOGA ON MOOD AND HEART RATE VARIABILITY IN PATIENTS AWAITING ORGAN TRANSPLANTATION: A PILOT STUDY. CONTEXT: RESEARCH SHOWS THAT LAUGHTER HAS MYRIAD HEALTH BENEFITS, YET THE MEDICAL COMMUNITY HAS NOT IMPLEMENTED IT FORMALLY AS A TREATMENT. PATIENTS AWAITING ORGAN TRANSPLANTATION HAVE SIGNIFICANT PHYSICAL DISABILITIES AND ARE AT RISK FOR PSYCHOLOGICAL DISTRESS. ATTENUATED HEART RATE VARIABILITY (HRV) IS A RISK FACTOR FOR A NEGATIVE LONG-TERM OUTCOME IN SOME PATIENTS. OBJECTIVE: THE STUDY INTENDED TO EVALUATE THE CLINICAL UTILITY OF LAUGHTER YOGA IN IMPROVING PSYCHOLOGICAL AND PHYSIOLOGICAL MEASURES IN OUTPATIENTS AWAITING ORGAN TRANSPLANTATION. POSITIVE RESULTS WOULD INDICATE PROMISING AREAS TO PURSUE IN A FOLLOW-UP STUDY. DESIGN: SIX PARTICIPANTS MET FOR 10 SESSIONS OVER 4 WEEKS. THE RESEARCH TEAM MEASURED EACH PARTICIPANT'S HEART RATE, HRV, BLOOD PRESSURE (BP), AND IMMEDIATE MOOD BEFORE AND AFTER THE LAUGHTER AND CONTROL INTERVENTIONS. THE TEAM ASSESSED PARTICIPANTS' LONGER-TERM MOOD (ANXIETY AND DEPRESSION) AT THE STUDY'S INITIATION, AFTER A NO-TREATMENT CONTROL WEEK, AND AT THE END OF THE STUDY. SETTING: THE STUDY OCCURRED AT THE DEPARTMENT OF SURGERY AND MEDICINE AT THE UNIVERSITY OF ARIZONA HEALTH SCIENCES CENTER, TUCSON. PARTICIPANTS: PARTICIPANTS WERE PATIENTS AWAITING TRANSPLANTS (THREE HEART AND THREE LUNG), TWO WOMEN AND FOUR MEN (AGES 51-69 Y). PARTICIPANTS HAD RECEIVED NO MAJOR SURGERY IN THE 3 MONTHS PRIOR TO THE INTERVENTION, DID NOT HAVE A HERNIA OR UNCONTROLLED HYPERTENSION, AND DID NOT FALL INTO THE NEW YORK HEART ASSOCIATION FUNCTION CLASS 4. INTERVENTION: THE 20-MINUTE LAUGHTER INTERVENTION INVOLVED BREATHING AND STRETCHING EXERCISES, SIMULATED LAUGHTER (IE, UNCONDITIONAL LAUGHTER THAT IS NOT CONTINGENT ON THE ENVIRONMENT), CHANTING, CLAPPING, AND A MEDITATION. THE 20-MINUTE CONTROL INTERVENTION INVOLVED THE STUDY'S PERSONNEL DISCUSSING HEALTH AND STUDY-RELATED TOPICS WITH THE PARTICIPANTS. OUTCOME MEASURES: THE RESEARCH TEAM MEASURED BP, HEART RATE, AND HRV AND ADMINISTERED THE PROFILE OF MOOD STATES, BECK ANXIETY INVENTORY, AND BECK DEPRESSION INVENTORY-II TO EVALUATE IMMEDIATE AND LONGER-TERM MOOD. THE TEAM HAD PLANNED QUANTITATIVE STATISTICAL ANALYSIS OF THE DATA AT THE STUDY'S INITIATION BUT DID NOT COMPLETE IT BECAUSE THE NUMBER OF ENROLLED PARTICIPANTS WAS TOO LOW FOR THE ANALYSIS TO BE MEANINGFUL. THE TEAM VISUALLY EXAMINED THE DATA, HOWEVER, FOR TRENDS THAT WOULD INDICATE AREAS TO EXAMINE FURTHER IN A FOLLOW-UP STUDY. RESULTS: PARTICIPANTS SHOWED IMPROVED IMMEDIATE MOOD (VIGOR-ACTIVITY AND FRIENDLINESS) AND INCREASED HRV AFTER THE LAUGHTER INTERVENTION. BOTH THE LAUGHTER AND CONTROL INTERVENTIONS APPEARED TO IMPROVE LONGER-TERM ANXIETY. TWO PARTICIPANTS AWAITING A LUNG TRANSPLANT DROPPED OUT OF THE STUDY, AND NO ADVERSE EVENTS OCCURRED. CONCLUSION: THIS PILOT STUDY SUGGESTS THAT LAUGHTER YOGA MAY IMPROVE HRV AND SOME ASPECTS OF MOOD, AND THIS TOPIC WARRANTS FURTHER RESEARCH.	2012	

6  858  48 EFFECT OF YOGA OR PHYSICAL EXERCISE ON PHYSICAL, COGNITIVE AND EMOTIONAL MEASURES IN CHILDREN: A RANDOMIZED CONTROLLED TRIAL. BACKGROUND: PREVIOUS STUDIES HAVE SEPARATELY REPORTED THE EFFECTS OF PHYSICAL EXERCISE AND YOGA IN CHILDREN, SHOWING PHYSICAL, COGNITIVE AND EMOTIONAL BENEFITS. OBJECTIVES: THE PRESENT RANDOMIZED CONTROLLED TRIAL ASSESSED THE EFFECTS OF YOGA OR PHYSICAL EXERCISE ON PHYSICAL FITNESS, COGNITIVE PERFORMANCE, SELF-ESTEEM, AND TEACHER-RATED BEHAVIOR AND PERFORMANCE, IN SCHOOL CHILDREN. METHODS: 98 SCHOOL CHILDREN BETWEEN 8 TO 13 YEARS WERE RANDOMIZED AS YOGA AND PHYSICAL EXERCISE GROUPS {N = 49 EACH; (YOGA: 15 GIRLS, GROUP MEAN AGE 10.4 +/- 1.2 YEARS), (PHYSICAL EXERCISE: 23 GIRLS, GROUP MEAN AGE 10.5 +/- 1.3 YEARS)}. BOTH GROUPS WERE BLIND ASSESSED AFTER ALLOCATION, USING: (I) THE EUROFIT PHYSICAL FITNESS TEST BATTERY, (II) STROOP COLOR-WORD TASK FOR CHILDREN, (III) BATTLE'S SELF-ESTEEM INVENTORY AND (IV) THE TEACHERS' RATING OF THE CHILDREN'S OBEDIENCE, ACADEMIC PERFORMANCE, ATTENTION, PUNCTUALITY, AND BEHAVIOR WITH FRIENDS AND TEACHERS. AFTER ASSESSMENTS THE YOGA GROUP PRACTICED YOGA (BREATHING TECHNIQUES, POSTURES, GUIDED RELAXATION AND CHANTING), 45 MINUTES EACH DAY, 5 DAYS A WEEK. DURING THIS TIME THE PHYSICAL EXERCISE GROUP HAD JOGGING-IN-PLACE, RAPID REPETITIVE MOVEMENTS AND RELAY RACES OR GAMES. BOTH GROUPS WERE ASSESSED AT THE END OF 3 MONTHS. DATA WERE ANALYZED WITH RM ANOVA AND POST-HOC TESTS WERE BONFERRONI ADJUSTED. RESULTS: THERE WAS ONE SIGNIFICANT DIFFERENCE BETWEEN GROUPS. THIS WAS IN SOCIAL SELF-ESTEEM WHICH WAS HIGHER AFTER PHYSICAL EXERCISE COMPARED TO YOGA (P < 0.05). ALL THE CHANGES REPORTED BELOW ARE BASED ON AFTER-BEFORE COMPARISONS, WITHIN EACH GROUP. BOTH GROUPS SHOWED AN INCREASE IN BMI, AND NUMBER OF SIT-UPS (P < 0.001). BALANCE WORSENED IN THE PHYSICAL EXERCISE GROUP, WHILE PLATE TAPPING IMPROVED IN THE YOGA GROUP (P < 0.001). IN THE STROOP TASK BOTH GROUPS SHOWED IMPROVED COLOR, WORD- AND COLOR-WORD NAMING (P < 0.01), WHILE THE PHYSICAL EXERCISE GROUP SHOWED HIGHER INTERFERENCE SCORES. TOTAL, GENERAL AND PARENTAL SELF-ESTEEM IMPROVED IN THE YOGA GROUP (P < 0.05). CONCLUSION: YOGA AND PHYSICAL EXERCISE ARE USEFUL ADDITIONS TO THE SCHOOL ROUTINE, WITH PHYSICAL EXERCISE IMPROVING SOCIAL SELF-ESTEEM. TRIAL REGISTRATION: THE STUDY WAS REGISTERED IN THE CLINICAL TRIALS REGISTRY OF INDIA (CTRI/2012/11/003112).	2013

TO THE BEST OF OUR KNOWLEDGE, THERE HAS BEEN NO STUDY THAT DEALS WITH THE FORMULATION OF A YOGA MODULE FOR THE PARTICULAR CLINICAL FEATURES OF DEPRESSION. AIM: THE MAIN AIM OF OUR STUDY WAS TO DEVELOP A COMPREHENSIVE YOGA THERAPY MODULE TARGETING SPECIFIC CLINICAL FEATURES OF DEPRESSION. SETTINGS AND DESIGN: SPECIFIC YOGA PRACTICES WERE MATCHED FOR CLINICAL FEATURES OF DEPRESSION BASED ON A THOROUGH LITERATURE REVIEW. A YOGA PROGRAM WAS DEVELOPED, WHICH CONSISTED OF SUKSMAVYAYAMA, (LOOSENING EXERCISES), ASANAS (POSTURES), RELAXATION TECHNIQUES, PRANAYAMA (BREATHING EXERCISES) AND CHANTING MEDITATION TO BE TAUGHT IN A 2 WEEK PERIOD. MATERIALS AND METHODS: A STRUCTURED QUESTIONNAIRE WAS DEVELOPED FOR VALIDATION FROM NINE EXPERIENCED YOGA PROFESSIONALS. THE FINAL VERSION OF YOGA THERAPY MODULE WAS PILOT-TESTED ON SEVEN PATIENTS (FIVE FEMALES) WITH DEPRESSION RECRUITED FROM OUTPATIENT SERVICE OF NATIONAL INSTITUTE OF MENTAL HEALTH AND NEURO SCIENCES, BANGALORE. RESULTS: THE FINAL YOGA THERAPY MODULE HAD THOSE PRACTICES THAT RECEIVED A SCORE OF THREE OR MORE (MODERATELY/VERY MUCH/EXTREMELY USEFUL) FROM ALL RESPONDERS. SIX OUT OF NINE (>65%) EXPERTS SUGGESTED SUKSMAVYAYAMA SHOULD BE INCLUDED. FIVE OUT OF NINE EXPERTS OPINED THAT TRAINING WITH 10 SESSIONS (OVER 2 WEEKS) IS RATHER SHORT. ALL EXPERTS OPINED THAT THE MODULE IS EASY TO TEACH, LEARN AND PRACTICE. AT THE PILOT STAGE, THE FIVE PATIENTS WHO COMPLETED THE MODULE REPORTED MORE THAN 80% SATISFACTION ABOUT THE YOGA PRACTICES AND HOW THE YOGA WAS TAUGHT. SEVERITY OF DEPRESSION SUBSTANTIALLY REDUCED AT BOTH 1 AND 3 MONTHS FOLLOW-UP. CONCLUSION: THE DEVELOPED COMPREHENSIVE YOGA THERAPY MODULE WAS VALIDATED BY EXPERTS IN THE FIELD AND WAS FOUND TO BE FEASIBLE AND USEFUL IN PATIENTS WITH DEPRESSION.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
8  985  37 EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. OBJECTIVES: TO EVALUATE EFFECTS OF HATHA YOGA AND OMKAR MEDITATION ON CARDIORESPIRATORY PERFORMANCE, PSYCHOLOGIC PROFILE, AND MELATONIN SECRETION. SUBJECTS AND METHODS: THIRTY HEALTHY MEN IN THE AGE GROUP OF 25-35 YEARS VOLUNTEERED FOR THE STUDY. THEY WERE RANDOMLY DIVIDED IN TWO GROUPS OF 15 EACH. GROUP 1 SUBJECTS SERVED AS CONTROLS AND PERFORMED BODY FLEXIBILITY EXERCISES FOR 40 MINUTES AND SLOW RUNNING FOR 20 MINUTES DURING MORNING HOURS AND PLAYED GAMES FOR 60 MINUTES DURING EVENING HOURS DAILY FOR 3 MONTHS. GROUP 2 SUBJECTS PRACTICED SELECTED YOGIC ASANAS (POSTURES) FOR 45 MINUTES AND PRANAYAMA FOR 15 MINUTES DURING THE MORNING, WHEREAS DURING THE EVENING HOURS THESE SUBJECTS PERFORMED PREPARATORY YOGIC POSTURES FOR 15 MINUTES, PRANAYAMA FOR 15 MINUTES, AND MEDITATION FOR 30 MINUTES DAILY, FOR 3 MONTHS. ORTHOSTATIC TOLERANCE, HEART RATE, BLOOD PRESSURE, RESPIRATORY RATE, DYNAMIC LUNG FUNCTION (SUCH AS FORCED VITAL CAPACITY, FORCED EXPIRATORY VOLUME IN 1 SECOND, FORCED EXPIRATORY VOLUME PERCENTAGE, PEAK EXPIRATORY FLOW RATE, AND MAXIMUM VOLUNTARY VENTILATION), AND PSYCHOLOGIC PROFILE WERE MEASURED BEFORE AND AFTER 3 MONTHS OF YOGIC PRACTICES. SERIAL BLOOD SAMPLES WERE DRAWN AT VARIOUS TIME INTERVALS TO STUDY EFFECTS OF THESE YOGIC PRACTICES AND OMKAR MEDITATION ON MELATONIN LEVELS. RESULTS: YOGIC PRACTICES FOR 3 MONTHS RESULTED IN AN IMPROVEMENT IN CARDIORESPIRATORY PERFORMANCE AND PSYCHOLOGIC PROFILE. THE PLASMA MELATONIN ALSO SHOWED AN INCREASE AFTER THREE MONTHS OF YOGIC PRACTICES. THE SYSTOLIC BLOOD PRESSURE, DIASTOLIC BLOOD PRESSURE, MEAN ARTERIAL PRESSURE, AND ORTHOSTATIC TOLERANCE DID NOT SHOW ANY SIGNIFICANT CORRELATION WITH PLASMA MELATONIN. HOWEVER, THE MAXIMUM NIGHT TIME MELATONIN LEVELS IN YOGA GROUP SHOWED A SIGNIFICANT CORRELATION (R = 0.71, P < 0.05) WITH WELL-BEING SCORE. CONCLUSION: THESE OBSERVATIONS SUGGEST THAT YOGIC PRACTICES CAN BE USED AS PSYCHOPHYSIOLOGIC STIMULI TO INCREASE ENDOGENOUS SECRETION OF MELATONIN, WHICH, IN TURN, MIGHT BE RESPONSIBLE FOR IMPROVED SENSE OF WELL-BEING.	2004	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
9  350  57 ASSESSMENT OF CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA IN ART OF LIVING PRACTITIONERS. OBJECTIVE: THE BREATHING PROCESSES ARE KNOWN TO MODULATE CARDIAC AUTONOMIC TONE AND IMPROVE PSYCHOLOGICAL STATUS. WE INVESTIGATED CARDIAC AUTONOMIC TONE FOLLOWING LONG SUDARSHAN KRIYA YOGA (SKY) USING HEART RATE VARIABILITY (HRV) AND SKIN CONDUCTANCE LEVEL (SCL). METHODS: THIRTY HEALTHY VOLUNTEERS (AGE 28.3 +/- 8.4 YEARS; 23 M: 7 F) PARTICIPATED IN THE STUDY. ELECTROCARDIOGRAM (ECG) AND SCL WERE RECORDED FOR 5 MIN EACH, BEFORE AND AFTER LONG SKY. LONG SKY IS A COMBINATION OF PRANAYAMA AND CYCLIC RHYTHMIC BREATHING AND IS PERFORMED BY FOLLOWING THE GUIDED AUDIO INSTRUCTIONS. HRV ANALYSIS WAS USED FOR THE ASSESSMENT OF CARDIAC AUTONOMIC TONE. TIME AND FREQUENCY DOMAIN PARAMETERS OF HRV WERE CALCULATED BY USING RR INTERVAL OF ECG. SCL WAS ACQUIRED USING GALVANIC SKIN RESPONSE (GSR) AMPLIFIER OF POWERLAB IN MICROSEIMENS (MUS). RESULTS: TIME DOMAIN PARAMETERS OF HRV, INCLUDING MEAN RR INTERVAL (P = 0.000), RESPIRATORY SINUS ARRHYTHMIA (RSA) (P = 0.037), STANDARD DEVIATION OF ALL NN INTERVALS (SDNN) (P = 0.013), NN50 COUNT DIVIDED BY THE TOTAL NUMBER OF ALL NN INTERVALS (PNN50) (P = 0.004), AND SQUARE ROOT OF THE MEAN OF THE SUM OF THE SQUARES OF DIFFERENCES BETWEEN ADJACENT NN INTERVALS (RMSSD) (P = 0.002) INCREASED, AND MEAN HEART RATE DECREASED (P = 0.000) FOLLOWING LONG SKY. IN FREQUENCY DOMAIN ANALYSIS, POWER OF LOW-FREQUENCY (LF) COMPONENT (P = 0.010) AND LF/HF RATIO (P = 0.008) DECREASED SIGNIFICANTLY, WHEREAS POWER OF HIGH FREQUENCY (HF) SIGNIFICANTLY INCREASED (P = 0.010). SCL DECREASED FOLLOWING LONG SKY, ALTHOUGH IT DID NOT ATTAIN STATISTICAL SIGNIFICANCE. CONCLUSIONS: THE RESULTS SUGGEST THAT LONG SKY INDUCES SIGNIFICANT OSCILLATIONS IN CARDIAC AUTONOMIC TONE. PARASYMPATHETIC ACTIVITY INCREASES AND SYMPATHETIC ACTIVITY DECREASES AND SYMPATHOVAGAL BALANCE IMPROVES FOLLOWING LONG SKY. DECREASE IN SYMPATHETIC ACTIVITY IS ALSO DEMONSTRATED BY DECREASE IN CONDUCTANCE ALTHOUGH IT DID NOT REACH STATISTICAL SIGNIFICANCE. FROM THIS STUDY IT CAN BE CONCLUDED THAT LONG SKY HAS A BENEFICIAL EFFECT ON CARDIAC AUTONOMIC TONE, AND PSYCHOPHYSIOLOGICAL RELAXATION. IT MAY SERVE AS A TOOL TO IMPROVE HRV, WHICH IS THE MARKER OF CARDIOVASCULAR HEALTH.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
10 1317  42 HEART RATE VARIABILITY CHANGES DURING HIGH FREQUENCY YOGA BREATHING AND BREATH AWARENESS. BACKGROUND: PRE AND POST COMPARISON AFTER ONE MINUTE OF HIGH FREQUENCY YOGA BREATHING (HFYB) SUGGESTED THAT THE HFYB MODIFIES THE AUTONOMIC STATUS BY INCREASING SYMPATHETIC MODULATION, BUT ITS EFFECT DURING THE PRACTICE WAS NOT ASSESSED. METHODS: THIRTY-EIGHT MALE VOLUNTEERS WITH GROUP AVERAGE AGE +/- S.D., 23.3 +/- 4.4 YEARS WERE EACH ASSESSED ON TWO SEPARATE DAYS IN TWO SESSIONS, (I) HFYB AND (II) BREATH AWARENESS. EACH SESSION WAS FOR 35 MINUTES, WITH 3 PERIODS, I.E., PRE (5 MINUTES), DURING HFYB OR BREATH AWARENESS (15 MINUTES) AND POST (5 MINUTES). RESULTS: THERE WAS A SIGNIFICANT DECREASE IN NN50, PNN50 AND THE MEAN RR INTERVAL DURING AND AFTER HFYB AND AFTER BREATH AWARENESS, COMPARED TO THE RESPECTIVE 'PRE' VALUES (P < 0.05) (REPEATED MEASURES ANOVA FOLLOWED BY POST-HOC ANALYSIS). THE LF POWER INCREASED AND HF POWER DECREASED DURING AND AFTER BREATH AWARENESS AND LF/HF RATIO INCREASED AFTER BREATH AWARENESS (P < 0.05). CONCLUSION: THE RESULTS SUGGEST THAT THERE WAS REDUCED PARASYMPATHETIC MODULATION DURING AND AFTER HFYB AND INCREASED SYMPATHETIC MODULATION WITH REDUCED PARASYMPATHETIC MODULATION DURING AND AFTER BREATH AWARENESS.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
11  867  41 EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY IN CORONARY ARTERY DISEASE PATIENTS: A RANDOMIZED CONTROLLED STUDY. BACKGROUND: LUNG FUNCTIONS ARE FOUND TO BE IMPAIRED IN CORONARY ARTERY DISEASE (CAD), CONGESTIVE HEART FAILURE, LEFT VENTRICULAR DYSFUNCTION, AND AFTER CARDIAC SURGERY. DIFFUSION CAPACITY PROGRESSIVELY WORSENS AS THE SEVERITY OF CAD INCREASES DUE TO REDUCTION IN LUNG TISSUE PARTICIPATING IN GAS EXCHANGE. AIMS AND OBJECTIVES: PRANAYAMA BREATHING EXERCISES AND YOGIC POSTURES MAY PLAY AN IMPRESSIVE ROLE IN IMPROVING CARDIO-RESPIRATORY EFFICIENCY AND FACILITATING GAS DIFFUSION AT THE ALVEOLO-CAPILLARY MEMBRANE. THIS STUDY WAS DONE TO SEE THE EFFECT OF YOGA REGIMEN ON LUNG FUNCTIONS PARTICULARLY DIFFUSION CAPACITY IN CAD PATIENTS. MATERIALS AND METHODS: A TOTAL OF 80 STABLE CAD PATIENTS BELOW 65 YEARS OF AGE OF BOTH SEXES WERE SELECTED AND RANDOMIZED INTO TWO GROUPS OF 40 EACH. GROUP I CAD PATIENTS WERE GIVEN YOGA REGIMEN FOR 3 MONTHS WHICH CONSISTED OF YOGIC POSTURES, PRANAYAMA BREATHING EXERCISES, DIETARY MODIFICATION, AND HOLISTIC TEACHING ALONG WITH THEIR CONVENTIONAL MEDICINE WHILE GROUP II CAD PATIENTS WERE PUT ONLY ON CONVENTIONAL MEDICINE. LUNG FUNCTIONS INCLUDING DIFFUSION CAPACITY WERE RECORDED THRICE IN BOTH THE GROUPS: 0 DAY AS BASELINE, 22(ND) DAY AND ON 90(TH) DAY BY USING COMPUTERIZED MS MEDISOFT CARDIO-RESPIRATORY INSTRUMENT, HYP'AIR COMPACT MODEL OF CARDIO-RESPIRATORY TESTING MACHINE WAS MANUFACTURED BY P K MORGAN, INDIA. THE RECORDED PARAMETERS WERE STATISTICALLY ANALYZED BY REPEATED MEASURES ANOVA FOLLOWED BY TUKEY'S TEST IN BOTH THE GROUPS. CARDIOVASCULAR PARAMETERS WERE ALSO COMPARED BEFORE AND AFTER INTERVENTION IN BOTH THE GROUPS. RESULTS: STATISTICALLY SIGNIFICANT IMPROVEMENTS WERE SEEN IN SLOW VITAL CAPACITY, FORCED VITAL CAPACITY, PEAK EXPIRATORY FLOW RATE, MAXIMUM VOLUNTARY VENTILATION, AND DIFFUSION FACTOR/ TRANSFER FACTOR OF LUNG FOR CARBON MONOXIDE AFTER 3 MONTHS OF YOGA REGIMEN IN GROUP I. FORCED EXPIRATORY VOLUME IN 1(ST) SEC (FEV1), AND FEV1 % ALSO SHOWED A TREND TOWARD IMPROVEMENT ALTHOUGH NOT STATISTICALLY SIGNIFICANT. HR, SBP AND DBP ALSO SHOWED SIGNIFICANT IMPROVEMENT IN GROUP-I PATIENTS WHO FOLLOWED YOGA REGIMEN. CONCLUSIONS: YOGA REGIMEN WAS FOUND TO IMPROVE LUNG FUNCTIONS AND DIFFUSION CAPACITY IN CAD PATIENTS BESIDES IMPROVING CARDIOVASCULAR FUNCTIONS. THUS, IT CAN BE USED AS A COMPLIMENTARY OR ADJUNCT THERAPY ALONG WITH THE CONVENTIONAL MEDICINE FOR THEIR TREATMENT AND REHABILITATION.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
12 2731  45 YOGA OFFERS CARDIOVASCULAR PROTECTION IN EARLY POSTMENOPAUSAL WOMEN. CONTEXT: POSTMENOPAUSE, AN ESTROGEN DEFICIENT STATE COMES WITH INCREASED INCIDENCE OF CARDIOVASCULAR DISEASES (CVDS). YOGA HAS BEEN DESCRIBED AS HAVING A BENEFICIAL EFFECT ON HEART RATE VARIABILITY (HRV), A MARKER FOR CARDIAC AUTONOMIC ACTIVITY WHICH CAN ASSESS CARDIOVASCULAR RISK, IN VARIOUS POPULATIONS. AIM: THE AIM OF THE STUDY WAS TO STUDY THE EFFECT OF 3-MONTH LONG YOGA PRACTICE ON HRV IN EARLY POSTMENOPAUSAL WOMEN. SETTINGS AND DESIGN: A PROSPECTIVE LONGITUDINAL STUDY OF 67 WOMEN WITHIN 5 YEARS OF MENOPAUSE BETWEEN 45 AND 60 YEARS OF AGE ATTENDING MENOPAUSE CLINIC OF DEPARTMENT OF GYNAECOLOGY, SUCHETA KRIPLANI HOSPITAL FULFILLING INCLUSION AND EXCLUSION CRITERIA AND CONSENTING WERE ENROLLED FOR THE STUDY. SUBJECTS AND METHODS: HRV OF 37 CASES (YOGA GROUP) AND 30 CONTROLS (NON-YOGA GROUP) WAS RECORDED PRE AND 3-MONTH POSTINTERVENTION. STATISTICAL ANALYSIS USED: GRAPHPAD PRISM VERSION 5 SOFTWARE WAS USED. VALUES ARE A MEAN AND STANDARD ERROR OF MEAN. STATISTICAL SIGNIFICANCE WAS SET UP AT P < 0.05. RESULTS: IN HRV, FREQUENCY DOMAIN ANALYSIS SHOWED A SIGNIFICANT FALL IN LOW FREQUENCY (LF) IN NORMALIZED UNITS (NU) AND LF: HIGH FREQUENCY (HF) RATIO AND SIGNIFICANT RISE IN HF IN NU IN THE YOGA GROUP (DEPICTING PARASYMPATHETIC DOMINANCE) AGAINST A SIGNIFICANT RISE IN LF (NU) AND LF: HF RATIO AND SIGNIFICANT FALL IN HF (NU) IN NON-YOGA GROUP (INDICATING SYMPATHETIC DOMINANCE). TIME DOMAIN ANALYSIS SHOWED A SIGNIFICANT DECREASE IN STANDARD DEVIATION OF NN INTERVALS IN NON-YOGA GROUP AGAINST NONSIGNIFICANT CHANGES IN YOGA GROUP INDICATING DETERIORATION IN PARASYMPATHETIC ACTIVITY IN NON-YOGA GROUP. CONCLUSIONS: THREE-MONTH LONG YOGA PRACTICE IMPROVED HRV IN EARLY POSTMENOPAUSAL WOMEN SIGNIFICANTLY AND HAS THE POTENTIAL TO ATTENUATE THE CVD RISK IN POSTMENOPAUSAL WOMEN.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                    
13  165  42 A RANDOMIZED CONTROL TRIAL OF THE EFFECT OF YOGA ON VERBAL AGGRESSIVENESS IN NORMAL HEALTHY VOLUNTEERS. OBJECTIVE: TO STUDY THE EFFECT OF YOGA ON VERBAL AGGRESSIVENESS IN NORMAL HEALTHY ADULTS. METHODS: OF THE 1228 PERSONS WHO ATTENDED INTRODUCTORY LECTURES, 226 SUBJECTS OF BOTH SEXES WHO SATISFIED THE INCLUSION AND EXCLUSION CRITERIA AND WHO CONSENTED TO PARTICIPATE IN THE STUDY WERE RANDOMLY ALLOCATED INTO TWO GROUPS. THESE 226 SUBJECTS WERE BETWEEN THE AGES OF 17 AND 62 YEARS AND 173/226 COMPLETED THE EIGHT WEEKS OF INTERVENTION. THE YOGA (Y) GROUP PRACTISED AN INTEGRATED YOGA MODULE THAT INCLUDED ASANAS, PRANAYAMA, MEDITATION, NOTIONAL CORRECTION, AND DEVOTIONAL SESSIONS. THE CONTROL GROUP PRACTISED MILD TO MODERATE PHYSICAL EXERCISES (PE). BOTH GROUPS HAD SUPERVISED PRACTICES (BY TRAINED EXPERTS) FOR ONE HOUR DAILY, SIX DAYS A WEEK FOR EIGHT WEEKS. VERBAL AGGRESSIVENESS WAS ASSESSED BEFORE AND AFTER EIGHT WEEKS USING THE SELF-ADMINISTERED VERBAL AGGRESSIVE SCALE. RESULTS: THE BASELINE SCORE OF THE TWO GROUPS DID NOT DIFFER SIGNIFICANTLY (P = 0.66). THERE WAS A SIGNIFICANT DECREASE IN VERBAL AGGRESSIVENESS IN THE YOGA GROUP (P = 0.01 PAIRED SAMPLES T-TEST) WITH A NONSIGNIFICANT INCREASE IN THE PE GROUP. ANCOVA USING PRE- VALUES AS COVARIATES SHOWED A SIGNIFICANT DIFFERENCE BETWEEN THE GROUPS (P = 0.013). RMANOVA FOR INTERACTION BETWEEN THE SEXES OR AGE GROUPS IN CHANGE SCORES WERE NOT SIGNIFICANT. CONCLUSIONS: THIS STUDY HAS DEMONSTRATED THAT AN EIGHT WEEK INTERVENTION OF AN INTEGRATED YOGA MODULE DECREASED VERBAL AGGRESSIVENESS IN THE YOGA GROUP (IN MALES AND THOSE BELOW 25 YEARS OF AGE), WITH A NONSIGNIFICANT INCREASE IN THE PE GROUP.	2008	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
14 1578  56 MEASUREMENT OF THE EFFECT OF ISHA YOGA ON CARDIAC AUTONOMIC NERVOUS SYSTEM USING SHORT-TERM HEART RATE VARIABILITY. BACKGROUND: BENEFICIAL EFFECTS OF YOGA HAVE BEEN POSTULATED TO BE DUE TO MODULATION OF THE AUTONOMIC NERVOUS SYSTEM. OBJECTIVE: TO ASSESS THE EFFECT OF ISHA YOGA PRACTICES ON CARDIOVASCULAR AUTONOMIC NERVOUS SYSTEM THROUGH SHORT-TERM HEART RATE VARIABILITY (HRV). DESIGN OF THE STUDY: SHORT-TERM HRV OF LONG-TERM REGULAR HEALTHY 14 (12 MALES AND 2 FEMALES) ISHA YOGA PRACTITIONERS WAS COMPARED WITH THAT OF AGE- AND GENDER-MATCHED 14 (12 MALES AND 2 FEMALES) NON-YOGA PRACTITIONERS. METHODS AND MATERIALS: ECG LEAD II AND RESPIRATORY MOVEMENTS WERE RECORDED IN BOTH GROUPS USING POLYRITE DURING SUPINE REST FOR 5 MIN AND CONTROLLED DEEP BREATHING FOR 1 MINUTE. FREQUENCY DOMAIN ANALYSIS [RR INTERVAL IS THE MEAN OF DISTANCE BETWEEN SUBSEQUENT R WAVE PEAKS IN ECG], LOW FREQUENCY (LF) POWER, HIGH FREQUENCY (HF) POWER, LF NORMALIZED UNITS (NU), HF NU, LF/HF RATIO] AND TIME DOMAIN ANALYSIS [STANDARD DEVIATION OF NORMAL TO NORMAL INTERVAL (SDNN), SQUARE OF MEAN SQUARED DIFFERENCE OF SUCCESSIVE NORMAL TO NORMAL INTERVALS (RMSSD), NORMAL TO NORMAL INTERVALS WHICH ARE DIFFERING BY 50 MS (NN50), AND PERCENTAGE OF NN50 (PNN50)] OF HRV VARIABLES WERE ANALYZED FOR SUPINE REST. TIME DOMAIN ANALYSIS WAS RECORDED FOR DEEP BREATHING. RESULTS: RESULTS SHOWED STATISTICALLY SIGNIFICANT DIFFERENCES BETWEEN ISHA YOGA PRACTITIONERS AND CONTROLS IN BOTH FREQUENCY AND TIME DOMAIN ANALYSES OF HRV INDICES, WITH NO DIFFERENCE IN RESTING HEART RATE BETWEEN THE GROUPS. CONCLUSIONS: PRACTITIONERS OF ISHA YOGA SHOWED WELL-BALANCED BENEFICIAL ACTIVITY OF VAGAL EFFERENTS, AN OVERALL INCREASED HRV, AND SYMPATHOVAGAL BALANCE, COMPARED TO NON-YOGA PRACTITIONERS DURING SUPINE REST AND DEEP BREATHING.	2012	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
15 1318  47 HEART RATE VARIABILITY IN CHRONIC LOW BACK PAIN PATIENTS RANDOMIZED TO YOGA OR STANDARD CARE. BACKGROUND: CHRONIC PAIN CAN ALTER THE AUTONOMIC BALANCE WITH INCREASED SYMPATHETIC ACTIVITY REFLECTED IN ALTERED HEART RATE VARIABILITY (HRV). IT HAS BEEN PROPOSED THAT YOGA CAN BE USEFUL TO CORRECT THE AUTONOMIC IMBALANCE IN PATIENTS WITH CHRONIC PAIN WHO HAVE REDUCED HRV. METHODS AND DESIGNS: IN THE PRESENT RANDOMIZED CONTROLLED TRIAL 62 PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS (AGED BETWEEN 20 AND 45 YEARS, 32 MALES) WERE RANDOMIZED TO 2 GROUPS. ONE GROUP RECEIVED YOGA FOR 3 MONTHS WHILE THE OTHER GROUP CARRIED OUT STANDARD MEDICAL CARE BASED ON THE PHYSICIAN'S ADVICE. THE DURATION WAS THE SAME, I.E., 3 MONTHS. THE HEART RATE VARIABILITY AND RATE OF RESPIRATION WERE ASSESSED AT BASELINE AND AT THE END OF 3 MONTHS. RESULTS: THERE WAS A SIGNIFICANT DIFFERENCE IN THE BASELINE (PRE) VALUES BETWEEN GROUPS (P = 0.008) FOR RESPIRATION RATE WHICH WAS HIGHER IN THE YOGA GROUP. THE CHANGES REPORTED BELOW ARE PRE-POST COMPARISONS WITHIN EACH GROUP. THE YOGA GROUP SHOWED A SIGNIFICANT (P < 0.05; REPEATED MEASURES ANOVA, POST-HOC ANALYSES) DECREASE IN THE LF POWER OF HRV, RATE OF RESPIRATION AND A SIGNIFICANT INCREASE IN THE HF POWER OF HRV AND IN THE PNN50. CONCLUSION: THE RESULTS SUGGEST THAT YOGA PRACTICE CAN SHIFT THE AUTONOMIC BALANCE TOWARDS VAGAL DOMINANCE IN PATIENTS WITH CHRONIC LOW BACK PAIN ASSOCIATED WITH ALTERED ALIGNMENT OF INTERVERTEBRAL DISCS. TRIAL REGISTRATION: THE STUDY IS REGISTERED WITH THE CLINICAL TRIALS REGISTRY OF INDIA ( CTRI/2012/11/003094 ) AND CAN BE ACCESSED AT.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
16  667  44 EFFECT OF A 12-WEEK YOGA THERAPY PROGRAM ON MENTAL HEALTH STATUS IN ELDERLY WOMEN INMATES OF A HOSPICE. AIM AND OBJECTIVES: THIS STUDY WAS UNDERTAKEN TO EVALUATE THE EFFECTIVENESS OF YOGA ON THE MENTAL HEALTH STATUS OF ELDERLY WOMEN INMATES RESIDING IN A HOSPICE IN PUDUCHERRY. MATERIALS AND METHODS: FORTY ELDERLY WOMEN WERE RANDOMLY DIVIDED INTO YOGA AND WAIT-LISTED CONTROL GROUP. A YOGA THERAPY PROGRAM OF 60 MIN WAS GIVEN TWICE A WEEK FOR 12 WEEKS. THIS PROTOCOL WAS SPECIALLY DESIGNED FOR SENIOR CITIZENS, KEEPING IN MIND THEIR HEALTH STATUS AND PHYSICAL LIMITATIONS THAT INCLUDED SIMPLE WARM-UP AND BREATH-BODY MOVEMENT COORDINATION PRACTICES (JATHIS AND KRIYAS), STATIC STRETCHING POSTURES (ASANAS), BREATHING TECHNIQUES (PRANAYAMAS), AND RELAXATION. HAMILTON ANXIETY SCALE FOR MEASURING ANXIETY, HAMILTON RATING SCALE FOR DEPRESSION, AND ROSENBERG SELF-ESTEEM SCALE TO MEASURE SELF-ESTEEM WERE ADMINISTERED TO BOTH GROUPS BEFORE AND AFTER THE 12-WEEK STUDY PERIOD. DATA WERE ASSESSED FOR NORMALITY, AND APPROPRIATE PARAMETRIC AND NONPARAMETRIC STATISTICAL METHODS WERE APPLIED FOR INTRA- AND INTER-GROUP COMPARISONS. RESULTS: OVERALL, INTRA- AND INTER-GROUP COMPARISON OF PREPOST DATA SHOWED STATISTICALLY SIGNIFICANT (P < 0.001) DIFFERENCES FOR ALL THREE PARAMETERS. THERE WAS AN OVERALL IMPROVEMENT IN THE SCORES INDICATING DECREASED LEVELS OF DEPRESSION AND ANXIETY COUPLED WITH AN INCREASE IN THE LEVEL OF SELF-ESTEEM AFTER THE YOGA THERAPY PROGRAM. DISCUSSION: THE INFLUENCE OF YOGA IN THE REDUCTION OF DEPRESSION AND ANXIETY SCORES AND IMPROVEMENT IN SELF-ESTEEM SCORES IN ELDERLY WOMEN SUBJECTS IS EVIDENT FROM THIS STUDY. AS REPORTED IN EARLIER STUDIES, THIS MAY BE ATTRIBUTED TO CHANGES IN CENTRAL NEUROTRANSMITTERS SUCH AS GAMMA-AMINOBUTYRIC-ACID COUPLED WITH INCREASED PARASYMPATHETIC TONE AND DECREASED SYMPATHO-ADRENAL ACTIVITY. CONCLUSION: IT IS RECOMMENDED THAT YOGA SHOULD BE A PART OF HEALTH-CARE FACILITIES FOR ELDERLY AS IT CAN ENHANCE THE QUALITY OF LIFE BY IMPROVING THEIR OVERALL MENTAL HEALTH STATUS. IT COULD PROVIDE A HEALTHY AND POSITIVE ALTERNATIVE FROM DEPRESSING NEGATIVE THOUGHTS, AND GIVE THEM A SENSE OF PURPOSE AND HOPE.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                          
17 2863  34 YOGA-BASED GUIDED RELAXATION REDUCES SYMPATHETIC ACTIVITY JUDGED FROM BASELINE LEVELS. 35 MALE VOLUNTEERS WHOSE AGES RANGED FROM 20 TO 46 YEARS WERE STUDIED IN TWO SESSIONS OF YOGA-BASED GUIDED RELAXATION AND SUPINE REST. ASSESSMENTS OF AUTONOMIC VARIABLES WERE MADE FOR 15 SUBJECTS, BEFORE, DURING, AND AFTER THE PRACTICES, WHEREAS OXYGEN CONSUMPTION AND BREATH VOLUME WERE RECORDED FOR 25 SUBJECTS BEFORE AND AFTER BOTH TYPES OF RELAXATION. A SIGNIFICANT DECREASE IN OXYGEN CONSUMPTION AND INCREASE IN BREATH VOLUME WERE RECORDED AFTER GUIDED RELAXATION (PAIRED T TEST). THERE WERE COMPARABLE REDUCTIONS IN HEART RATE AND SKIN CONDUCTANCE DURING BOTH TYPES OF RELAXATION. DURING GUIDED RELAXATION THE POWER OF THE LOW FREQUENCY COMPONENT OF THE HEART-RATE VARIABILITY SPECTRUM REDUCED, WHEREAS THE POWER OF THE HIGH FREQUENCY COMPONENT INCREASED, SUGGESTING REDUCED SYMPATHETIC ACTIVITY. ALSO, SUBJECTS WITH A BASELINE RATIO OF LF/HF > 0.5 SHOWED A SIGNIFICANT DECREASE IN THE RATIO AFTER GUIDED RELAXATION, WHILE SUBJECTS WITH A RATIO < OR = 0.5 AT BASELINE SHOWED NO SUCH CHANGE. THE RESULTS SUGGEST THAT SYMPATHETIC ACTIVITY DECREASED AFTER GUIDED RELAXATION BASED ON YOGA, DEPENDING ON THE BASELINE LEVELS.	2002	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                
18 1060  44 EFFECTS OF YOGA ON FUNCTIONAL CAPACITY AND WELL BEING. YOGA HAS PROVEN BENEFICIAL EFFECTS ON VARIOUS HEALTH DOMAINS INCLUDING MUSCULOSKELETAL CONDITIONS, CARDIOPULMONARY CONDITIONS THROUGH THE PRACTICE OF ASANA AND PRANAYAMAS AS WELL AS ON MENTAL HEALTH, AS IT IS KNOWN TO ENHANCE THE BODY-AND MIND COORDINATION. THERE IS PAUCITY OF DATA ON THE EFFECT OF YOGA ON FUNCTIONAL CAPACITY IN LITERATURE USING 6 MIN WALK TEST. THE PRESENT STUDY AIMS TO LOOK AT THE EFFECT OF YOGA ON 6-MIN WALKED DISTANCE, RATING OF PERCEIVED EXERTION (RPE), RECOVERY TIME FOLLOWING THE WALK AND STATE OF WELL BEING. THIS IS A HOSPITAL-BASED LONGITUDINAL STUDY WHERE 30 PHYSIOTHERAPY STUDENTS OF THE AGE GROUP 18 - 22 YEARS OF EITHER SEX WERE ENROLLED. SUBJECTS HAVING MUSCULOSKELETAL PROBLEMS, CARDIO RESPIRATORY DISEASE AND THOSE WHO WERE NOT WILLING TO VOLUNTEER WERE EXCLUDED THEY RECEIVED YOGA INTERVENTION IN FORM OF YOGIC PRACTICES WHICH INCLUDED A COMBINATION OF ASANAS, PRANAYAMAS AND OMKAR CHANTING FOR 1 H FOR 30 SESSIONS. A BASELINE 6-MIN WALK TEST WAS CONDUCTED ON SUBJECTS AND THE 6-MIN WALKED DISTANCE, RATING OF PERCEIVED EXERTION (RPE) ON MODIFIED BORG'S SCALE WERE RECORDED. THE BASELINE STATE OF WELL-BEING WAS NOTED USING THE WARWICK- EDINBURGH MENTAL WELL-BEING SCALE AND SIMILAR RECORDING WAS DONE POST INTERVENTION AFTER 30 SESSIONS. OF THE 30 SUBJECTS, THERE WERE NO DROP OUTS AS THESE WERE COMMITTED COLLEGE STUDENTS. OF THEM, 24 WERE FEMALES AND 6 WERE MALES WITH A MEAN AGE OF 21.5 YEARS SD 2.38. STATISTICALLY SIGNIFICANT IMPROVEMENTS WERE OBSERVED IN 6-MIN WALK DISTANCE (P VALUE = 0.000), RPE (P VALUE < 0.000), RECOVERY TIME (P VALUE < 0.000) AND SENSE OF WELL BEING SCORE (P VALUE < 0.000). YOGA PRACTICES ARE BENEFICIAL IN IMPROVING THE FUNCTIONAL CAPACITY IN YOUNG HEALTHY ADULTS. YOGA CAN VERY WELL BE INCORPORATED IN MEDICAL PRACTICE FOR INCREASING THE PATIENT'S FUNCTIONAL CAPACITY, FOR THOSE WHO HAVE LIMITATIONS IN PERFORMING AEROBIC TRAINING DUE TO VARIOUS HEALTH REASONS. THE IMPROVED STATE OF WELL BEING MOTIVATES THE PATIENTS TO ADHERE TO YOGIC PRACTICES.	2013	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
19 2507  40 YOGA BASED CARDIAC REHABILITATION AFTER CORONARY ARTERY BYPASS SURGERY: ONE-YEAR RESULTS ON LVEF, LIPID PROFILE AND PSYCHOLOGICAL STATES--A RANDOMIZED CONTROLLED STUDY. OBJECTIVE: TO COMPARE THE LONG TERM EFFECTS OF YOGA BASED CARDIAC REHABILITATION PROGRAM WITH ONLY PHYSIOTHERAPY BASED PROGRAM AS AN ADD-ON TO CONVENTIONAL REHABILITATION AFTER CORONARY ARTERY BYPASS GRAFTING (CABG) ON RISK FACTORS. METHODS: IN THIS SINGLE BLIND PROSPECTIVE RANDOMIZED PARALLEL TWO ARMED ACTIVE CONTROL STUDY, 1026 PATIENTS POSTED FOR CABG AT NARAYANA HRUDAYALAYA INSTITUTE OF CARDIAC SCIENCES, BENGALURU (INDIA) WERE SCREENED. OF THESE, 250 MALE PARTICIPANTS (35-65 YEARS) WHO SATISFIED THE SELECTION CRITERIA AND CONSENTED WERE RANDOMIZED INTO TWO GROUPS. WITHIN AND BETWEEN GROUP COMPARISONS WERE DONE AT THREE POINTS OF FOLLOW UP (I.E. 6TH WEEK, 6TH MONTH, AND 12TH MONTH) BY USING WILCOXON'S SIGNED RANKS TEST AND MANN WHITNEY U TEST RESPECTIVELY. RESULTS: YOGA GROUP HAD SIGNIFICANTLY (P = 0.001, MANN WHITNEY) BETTER IMPROVEMENT IN LVEF THAN CONTROL GROUP IN THOSE WITH ABNORMAL BASELINE EF (<53%) AFTER 1 YEAR. THERE WAS A BETTER REDUCTION IN BMI IN THE YOGA GROUP (P = 0.038, BETWEEN GROUPS) IN THOSE WITH HIGH BASELINE BMI (>/=23) AFTER 12 MONTHS. YOGA GROUP SHOWED SIGNIFICANT (P = 0.008, WILCOXON'S) REDUCTION IN BLOOD GLUCOSE AT ONE YEAR IN THOSE WITH HIGH BASELINE FBS >/=110 MG/DL. THERE WAS SIGNIFICANTLY BETTER IMPROVEMENT IN YOGA THAN THE CONTROL GROUP IN HDL (P = 0.003), LDL (P = 0.01) AND VLDL (P = 0.03) IN THOSE WITH ABNORMAL BASELINE VALUES. THERE WAS SIGNIFICANTLY BETTER IMPROVEMENT (P = 0.02, BETWEEN GROUPS) IN POSITIVE AFFECT IN YOGA GROUP. WITHIN YOGA GROUP, THERE WAS SIGNIFICANT DECREASE IN PERCEIVED STRESS (P = 0.001), ANXIETY (P = 0.001), DEPRESSION (P = 0.001), AND NEGATIVE AFFECT (P = 0.03) WHILE IN THE CONTROL GROUP THERE WAS REDUCTION (P = 0.003) ONLY IN SCORES ON ANXIETY. CONCLUSION: ADDITION OF YOGA BASED RELAXATION TO CONVENTIONAL POST-CABG CARDIAC REHABILITATION HELPS IN BETTER MANAGEMENT OF RISK FACTORS IN THOSE WITH ABNORMAL BASELINE VALUES AND MAY HELP IN PREVENTING RECURRENCE.	2014	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                        
20  870  31 EFFECT OF YOGA THERAPY ON ANXIETY AND DEPRESSIVE SYMPTOMS AND QUALITY-OF-LIFE AMONG CAREGIVERS OF IN-PATIENTS WITH NEUROLOGICAL DISORDERS AT A TERTIARY CARE CENTER IN INDIA: A RANDOMIZED CONTROLLED TRIAL. CONTEXT: THE CONCERNS OF CAREGIVERS OF PATIENTS WITH NEUROLOGICAL DISORDERS HAVE BEEN A FELT NEED FOR A LONG TIME, WITH MANY OF THEM EXPERIENCING SIGNIFICANT PSYCHIATRIC MORBIDITY. AIMS: THIS STUDY AIMED TO FIND THE EFFECT OF YOGA IN REDUCING ANXIETY AND DEPRESSION, AS WELL AS IMPROVING QUALITY-OF-LIFE IN CAREGIVERS OF PATIENTS WITH NEUROLOGICAL DISORDERS. SETTINGS AND DESIGN: THE STUDY WAS CONDUCTED USING A RANDOMIZED CONTROLLED DESIGN, WITH YOGA INTERVENTION AND WAITLISTED CONTROLS. METHODOLOGY: SIXTY CONSENTING CAREGIVERS OF INPATIENTS IN NEUROLOGY WARDS WERE RANDOMIZED INTO TWO GROUPS: YOGA AND CONTROL. DEMOGRAPHIC VARIABLES EXCEPT YEARS OF EDUCATION AND LENGTH OF CARETAKING WERE COMPARABLE IN THE TWO GROUPS, AS ALSO BASELINE SCORES OF ANXIETY, DEPRESSION AND QUALITY-OF-LIFE. A SPECIFIC YOGA MODULE COMPRISING YOGASANAS, PRANAYAMA, AND CHANTING WAS TAUGHT TO THE PARTICIPANTS IN THE YOGA GROUP BY THE RESEARCHER. AT FOLLOW-UP 43 PATIENTS (YOGA N=20 AND CONTROL GROUP N=23) WERE AVAILABLE. TWO-WAY REPEATED MEASURES ANALYSIS OF VARIANCE WAS USED TO TEST THE CHANGE FROM PRE-TEST TO POST-TEST SCORES WITHIN AND BETWEEN GROUPS. ANALYSIS OF COVARIANCE WAS PERFORMED TO COMPARE THE POST-TEST SCORES BETWEEN THE GROUPS ADJUSTING FOR EDUCATION AND LENGTH OF CARETAKING. RESULTS: FOLLOWING ONE MONTH INTERVENTION OF YOGA THERAPY, THERE WAS A SIGNIFICANT (P<0.001) DECREASE IN ANXIETY AND DEPRESSION SCORES, AS WELL AS IMPROVED QUALITY-OF-LIFE AMONG THE PARTICIPANTS IN THE YOGA GROUP AS COMPARED WITH THE CONTROL GROUP. CONCLUSION: THIS STUDY HIGHLIGHTS THE USEFULNESS OF A YOGA INTERVENTION FOR CAREGIVERS OF INPATIENTS WITH NEUROLOGICAL PROBLEMS. THE SMALL SAMPLE SIZE AND LACK OF BLINDING WERE SOME OF THE LIMITATIONS OF THIS STUDY.	2013
