1 1329 163 HIGH-FREQUENCY CEREBRAL ACTIVATION AND INTERHEMISPHERIC SYNCHRONIZATION FOLLOWING SUDARSHAN KRIYA YOGA AS GLOBAL BRAIN RHYTHMS: THE STATE EFFECTS. CONTEXT: RESPIRATION IS KNOWN TO MODULATE NEURONAL OSCILLATIONS IN THE BRAIN AND IS MEASURED BY ELECTROENCEPHALOGRAM (EEG). SUDARSHAN KRIYA YOGA (SKY) IS A POPULAR BREATHING PROCESS AND IS ESTABLISHED FOR ITS SIGNIFICANT EFFECTS ON THE VARIOUS ASPECTS OF PHYSIOLOGY AND PSYCHOLOGY. AIMS: THIS STUDY AIMED TO OBSERVE NEURONAL OSCILLATIONS IN MULTIFREQUENCY BANDS AND INTERHEMISPHERIC SYNCHRONIZATION FOLLOWING SKY. SETTINGS AND DESIGN: THIS STUDY EMPLOYED BEFORE- AND AFTER-STUDY DESIGN. SUBJECTS AND METHODS: FORTY HEALTHY VOLUNTEERS (AVERAGE AGE 25.45 +/- 5.75, 23 MALES AND 17 FEMALES) PARTICIPATED IN THE STUDY. NINETEEN-CHANNEL EEG WAS RECORDED AND ANALYZED FOR 5 MIN EACH: BEFORE AND AFTER SKY. SPECTRAL POWER FOR DELTA, THETA, ALPHA, BETA, AND GAMMA FREQUENCY BAND WAS CALCULATED USING MULTI-TAPER FAST FOURIER TRANSFORM (CHRONUX TOOLBOX). THE ASYMMETRY INDEX WAS CALCULATED BY SUBTRACTING THE NATURAL LOG OF POWERS OF LEFT (L) HEMISPHERE FROM THE RIGHT((R)) TO SHOW INTERHEMISPHERIC SYNCHRONIZATION. STATISTICAL ANALYSIS: PAIRED T-TEST WAS USED FOR STATISTICAL ANALYSIS. RESULTS: SPECTRAL POWER INCREASED SIGNIFICANTLY IN ALL FREQUENCY BANDS BILATERALLY IN FRONTAL, CENTRAL, PARIETAL, TEMPORAL, AND OCCIPITAL REGIONS OF THE BRAIN AFTER LONG SKY. ELECTRICAL ACTIVITY SHIFTED FROM LOWER TO HIGHER FREQUENCY RANGE WITH A SIGNIFICANT RISE IN THE GAMMA AND BETA POWERS FOLLOWING SKY. ASYMMETRY INDEX VALUES TENDED TOWARD 0 FOLLOWING SKY. CONCLUSIONS: A SINGLE SESSION OF SKY GENERATES GLOBAL BRAIN RHYTHM DOMINANTLY WITH HIGH-FREQUENCY CEREBRAL ACTIVATION AND INITIATES APPROPRIATE INTERHEMISPHERIC SYNCHRONIZATION IN BRAIN RHYTHMS AS STATE EFFECTS. THIS SUGGESTS THAT SKY LEADS TO BETTER ATTENTION, MEMORY, AND EMOTIONAL AND AUTONOMIC CONTROL ALONG WITH ENHANCED COGNITIVE FUNCTIONS, WHICH FINALLY IMPROVES PHYSICAL AND MENTAL WELL-BEING.	2020	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
2  499  47 COMBINED YOGA AND TRANSCRANIAL DIRECT CURRENT STIMULATION INCREASE FUNCTIONAL CONNECTIVITY AND SYNCHRONIZATION IN THE FRONTAL AREAS. TRANSCRANIAL DIRECT CURRENT STIMULATION (TDCS) IS A NON-INVASIVE NEURO-STIMULATION TECHNIQUE THAT CAN MODULATE CORTICAL EXCITABILITY. SIMILARLY, YOGA IS SHOWN TO AFFECT THE BRAIN'S NEURAL ACTIVITY AND NETWORKS. HERE, WE AIMED TO INVESTIGATE THE EFFECT OF COMBINED YOGA AND TDCS ON BRAIN OSCILLATIONS AND NETWORKS USING RESTING-STATE ELECTROENCEPHALOGRAPHY RECORDINGS. IN A RANDOMIZED, CROSS-OVER, DOUBLE-BLIND DESIGN, TWENTY-TWO HEALTHY SUBJECTS PARTICIPATED IN A YOGA/ACTIVE TDCS SESSION (2 MA; 20 MIN; ANODE-F3, CATHODE F4) OR YOGA/SHAM TDCS ON 2 SEPARATE DAYS. RESTING-STATE EEG DATA WERE COLLECTED BEFORE AND AFTER EACH INTERVENTION. POWER SPECTRAL DENSITY (PSD) AND FUNCTIONAL CONNECTIVITY, MEASURED BY A SYNCHRONIZATION MEASURE, PHASE-LOCKING VALUE, WERE COMPUTED FOR EACH CONDITION. THERE WERE NO SIGNIFICANT DIFFERENCES IN PSD VALUES AMONG THE TWO INTERVENTIONS. THE NETWORK-BASED STATISTIC METHOD WAS EMPLOYED FOR DETECTING FUNCTIONAL CONNECTIVITY DIFFERENCES BETWEEN YOGA/ACTIVE AND YOGA/SHAM TDCS INTERVENTIONS. RESULTS SHOW THAT THE ADDITION OF ACTIVE TDCS TO YOGA IS ASSOCIATED WITH INCREASED FUNCTIONAL CONNECTIVITY OF THE SCALP AND SOURCE EEG DATA IN THE FRONTAL AREA. THE CHANGES WERE WIDESPREAD, INTRA-HEMISPHERIC, AND INTER-HEMISPHERIC CONNECTIONS, WHICH WERE MAINLY BETWEEN THE FRONTAL AREA TO OTHER REGIONS. AT THE SOURCE LEVEL, MOST OF THE CONNECTIVITY CHANGES WERE FOUND IN THE FRONTO-PARIETAL NETWORK. THESE FINDINGS SUGGEST THAT COMBINING YOGA WITH TDCS MIGHT LEAD TO BRAIN NETWORK CHANGES RELATED TO THE EXECUTIVE AND ATTENTIONAL FUNCTIONS.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
3  408  29 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
4  744  32 EFFECT OF ROSARY PRAYER AND YOGA MANTRAS ON AUTONOMIC CARDIOVASCULAR RHYTHMS: COMPARATIVE STUDY. OBJECTIVE: TO TEST WHETHER RHYTHMIC FORMULAS SUCH AS THE ROSARY AND YOGA MANTRAS CAN SYNCHRONISE AND REINFORCE INHERENT CARDIOVASCULAR RHYTHMS AND MODIFY BAROREFLEX SENSITIVITY. DESIGN: COMPARISON OF EFFECTS OF RECITATION OF THE AVE MARIA (IN LATIN) OR OF A MANTRA, DURING SPONTANEOUS AND METRONOME CONTROLLED BREATHING, ON BREATHING RATE AND ON SPONTANEOUS OSCILLATIONS IN RR INTERVAL, AND ON BLOOD PRESSURE AND CEREBRAL CIRCULATION. SETTING: FLORENCE AND PAVIA, ITALY. PARTICIPANTS: 23 HEALTHY ADULTS. MAIN OUTCOME MEASURES: BREATHING RATE, REGULARITY OF BREATHING, BAROREFLEX SENSITIVITY, FREQUENCY OF CARDIOVASCULAR OSCILLATIONS. RESULTS: BOTH PRAYER AND MANTRA CAUSED STRIKING, POWERFUL, AND SYNCHRONOUS INCREASES IN EXISTING CARDIOVASCULAR RHYTHMS WHEN RECITED SIX TIMES A MINUTE. BAROREFLEX SENSITIVITY ALSO INCREASED SIGNIFICANTLY, FROM 9.5 (SD 4.6) TO 11.5 (4.9) MS/MM HG, P<0.05. CONCLUSION: RHYTHM FORMULAS THAT INVOLVE BREATHING AT SIX BREATHS PER MINUTE INDUCE FAVOURABLE PSYCHOLOGICAL AND POSSIBLY PHYSIOLOGICAL EFFECTS.	2001	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  
5   81  22 A MATHEMATICAL MODEL OF EFFECTS ON SPECIFIC JOINTS DURING PRACTICE OF THE SUN SALUTATION--A SEQUENCE OF YOGA POSTURES. THE 'SUN SALUTATION' CONSISTS OF A SEQUENCE OF TEN YOGA POSTURES, EACH POSTURE COUNTERACTING THE PRECEDING ONE PRODUCING A BALANCE BETWEEN FLEXION AND EXTENSION, PERFORMED WITH SYNCHRONIZED BREATHING AND AEROBIC ACTIVITY. AS THIS SEQUENCE IS OFTEN PERFORMED AND RECOMMENDED BY MANY YOGA PRACTITIONERS, THERE IS A NEED FOR THE DEVELOPMENT OF A BIOMECHANICAL MODEL TO SUPPORT ITS REPORTED CLINICAL BENEFITS. THIS REQUIRES A DETAILED KNOWLEDGE OF THE NATURE OF THE FORCES AND MOMENTS AT THE VARIOUS JOINTS INVOLVED. A SIMPLE MATHEMATICAL MODEL BASED ON RIGID BODY MECHANICS IS DEVELOPED FOR EACH OF THE SUN SALUTATION POSTURES. DYNAMIC MOMENTS WITH HIGH MAGNITUDES AND RATES, APPLIED WITH UNUSUAL DISTRIBUTION PATTERNS, OPTIMAL FOR OSTEOGENESIS, ARE FOUND TO OCCUR. ALSO, THE JOINTS ARE SUBJECTED TO SUBMAXIMAL LOADINGS THUS ENSURING THAT NONE OF THE JOINTS ARE OVERSTRESSED.	2011	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
6  253  32 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	

7  492  45 COGNITIVE BEHAVIOR EVALUATION BASED ON PHYSIOLOGICAL PARAMETERS AMONG YOUNG HEALTHY SUBJECTS WITH YOGA AS INTERVENTION. OBJECTIVE: TO INVESTIGATE THE EFFECT OF YOGA PRACTICE ON COGNITIVE SKILLS, AUTONOMIC NERVOUS SYSTEM, AND HEART RATE VARIABILITY BY ANALYZING PHYSIOLOGICAL PARAMETERS. METHODS: THE STUDY WAS CONDUCTED ON 30 NORMAL YOUNG HEALTHY ENGINEERING STUDENTS. THEY WERE RANDOMLY SELECTED INTO TWO GROUPS: YOGA GROUP AND CONTROL GROUP. THE YOGA GROUP PRACTICED YOGA ONE AND HALF HOUR PER DAY FOR SIX DAYS IN A WEEK, FOR A PERIOD OF FIVE MONTHS. RESULTS: THE YOGA PRACTISING GROUP SHOWED INCREASED ALPHA, BETA, AND DELTA EEG BAND POWERS AND SIGNIFICANT REDUCTION IN THETA AND GAMMA BAND POWERS. THE INCREASED ALPHA AND BETA POWER CAN REPRESENT ENHANCED COGNITIVE FUNCTIONS SUCH AS MEMORY AND CONCENTRATION, AND THAT OF DELTA SIGNIFIES SYNCHRONIZATION OF BRAIN ACTIVITY. THE HEART RATE INDEX THETA/ALPHA DECREASED, NEURAL ACTIVITY BETA/THETA INCREASED, ATTENTION RESOURCE INDEX BETA/(ALPHA + THETA) INCREASED, EXECUTIVE LOAD INDEX (DELTA + THETA)/ALPHA DECREASED, AND THE RATIO (DELTA + THETA)/(ALPHA + BETA) DECREASED. THE YOGA PRACTICE GROUP SHOWED IMPROVEMENT IN HEART RATE VARIABILITY, INCREASED SDNN/RMSSD, AND REDUCTION IN LF/HF RATIO. CONCLUSION: YOGA PRACTISING GROUP SHOWED SIGNIFICANT IMPROVEMENT IN VARIOUS COGNITIVE FUNCTIONS, SUCH AS PERFORMANCE ENHANCEMENT, NEURAL ACTIVITY, ATTENTION, AND EXECUTIVE FUNCTION. IT ALSO RESULTED IN INCREASE IN THE HEART RATE VARIABILITY, PARASYMPATHETIC NERVOUS SYSTEM ACTIVITY, AND BALANCED AUTONOMIC NERVOUS SYSTEM REACTIVITY.	2015	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
8 1208  54 EXPLORATION OF LOWER FREQUENCY EEG DYNAMICS AND CORTICAL ALPHA ASYMMETRY IN LONG-TERM RAJYOGA MEDITATORS. BACKGROUND: RAJYOGA MEDITATION IS TAUGHT BY PRAJAPITA BRAHMAKUMARIS WORLD SPIRITUAL UNIVERSITY (BRAHMAKUMARIS) AND HAS BEEN FOLLOWED BY MORE THAN ONE MILLION FOLLOWERS ACROSS THE GLOBE. HOWEVER, RARE STUDIES WERE CONDUCTED ON PHYSIOLOGICAL ASPECTS OF RAJYOGA MEDITATION USING ELECTROENCEPHALOGRAPHY (EEG). BAND POWER AND CORTICAL ASYMMETRY WERE NOT STUDIED WITH RAJYOGA MEDITATORS. AIMS: THIS STUDY AIMS TO INVESTIGATE THE EFFECT OF REGULAR MEDITATION PRACTICE ON EEG BRAIN DYNAMICS IN LOW-FREQUENCY BANDS OF LONG-TERM RAJYOGA MEDITATORS. SETTINGS AND DESIGN: SUBJECTS WERE MATCHED FOR AGE IN BOTH GROUPS. LOWER FREQUENCY EEG BANDS WERE ANALYZED IN RESTING AND DURING MEDITATION. MATERIALS AND METHODS: TWENTY-ONE MALE LONG-TERM MEDITATORS (LTMS) AND SAME NUMBER OF CONTROLS WERE SELECTED TO PARTICIPATE IN STUDY AS PAR INCLUSION CRITERIA. SEMI HIGH-DENSITY EEG WAS RECORDED BEFORE AND DURING MEDITATION IN LTM GROUP AND RESTING IN CONTROL GROUP. THE MAIN OUTCOME OF THE STUDY WAS SPECTRAL POWER OF ALPHA AND THETA BANDS AND CORTICAL (HEMISPHERICAL) ASYMMETRY CALCULATED USING BAND POWER. STATISTICAL ANALYSIS: ONE-WAY ANOVA WAS PERFORMED TO FIND THE SIGNIFICANT DIFFERENCE BETWEEN EEG SPECTRAL PROPERTIES OF GROUPS. PEARSON'S CHI-SQUARE TEST WAS USED TO FIND DIFFERENCE AMONG DEMOGRAPHICS DATA. RESULTS: RESULTS REVEAL HIGH-BAND POWER IN ALPHA AND THETA SPECTRA IN MEDITATORS. CORTICAL ASYMMETRY CALCULATED THROUGH EEG POWER WAS ALSO FOUND TO BE HIGH IN FRONTAL AS WELL AS PARIETAL CHANNELS. HOWEVER, NO CORRELATION WAS SEEN BETWEEN THE EXPERIENCE OF MEDITATION (YEARS, HOURS) PRACTICE AND EEG INDICES. CONCLUSION: OVERALL FINDINGS INDICATE CONTRIBUTION OF SMALLER FREQUENCIES (ALPHA AND THETA) WHILE MAINTAINING MEDITATIVE EXPERIENCE. THIS SUGGESTS A POSITIVE IMPACT OF MEDITATION ON FRONTAL AND PARIETAL AREAS OF BRAIN, INVOLVED IN THE PROCESSES OF REGULATION OF SELECTIVE AND SUSTAINED ATTENTION AS WELL AS PROVIDE EVIDENCE ABOUT THEIR INVOLVEMENT IN EMOTION AND COGNITIVE PROCESSING.	2018	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
9 1565  48 LOW AND THEN HIGH FREQUENCY OSCILLATIONS OF DISTINCT RIGHT CORTICAL NETWORKS ARE PROGRESSIVELY ENHANCED BY MEDIUM AND LONG TERM SATYANANDA YOGA MEDITATION PRACTICE. MEDITATION PROFICIENCY IS RELATED TO TRAIT-LIKE (LEARNED) EFFECTS ON BRAIN FUNCTION, DEVELOPED OVER TIME. PREVIOUS STUDIES SHOW INCREASES IN EEG POWER IN LOWER FREQUENCY BANDS (THETA, ALPHA) IN EXPERIENCED MEDITATORS IN BOTH MEDITATION STATES AND BASELINE CONDITIONS. HIGHER GAMMA BAND POWER HAS BEEN FOUND IN ADVANCED BUDDHIST MEDITATORS, YET IT IS NOT KNOWN IF THIS OCCURS IN YOGA MEDITATION PRACTICES. THIS STUDY USED ELORETA TO COMPARE DIFFERENCES IN CORTICAL SOURCE ACTIVITY UNDERLYING SCALP EEG FROM INTERMEDIATE (MEAN EXPERIENCE 4 YEARS) AND ADVANCED (MEAN EXPERIENCE 30 YEARS) AUSTRALIAN MEDITATORS FROM THE SATYANANDA YOGA TRADITION DURING A BODY-STEADINESS MEDITATION, MANTRA MEDITATION, AND NON-MEDITATION MENTAL CALCULATION CONDITION. INTERMEDIATE YOGA MEDITATORS SHOWED GREATER SOURCE ACTIVITY IN LOW FREQUENCIES (PARTICULARLY THETA AND ALPHA1) DURING MENTAL CALCULATION, BODY-STEADINESS AND MANTRA MEDITATION. A SIMILAR SPATIAL PATTERN OF SIGNIFICANT DIFFERENCES WAS FOUND IN ALL CONDITIONS BUT THE NUMBER OF SIGNIFICANT VOXELS WAS DOUBLE DURING BODY-STEADINESS AND MANTRA MEDITATION THAN IN THE NON-MEDITATION (CALCULATION) CONDITION. THESE DIFFERENCES WERE GREATEST IN RIGHT (R) SUPERIOR FRONTAL AND R PRECENTRAL GYRI AND EXTENDED BACK TO INCLUDE THE R PARIETAL AND OCCIPITAL LOBES. ADVANCED YOGA MEDITATORS SHOWED GREATER ACTIVITY IN HIGH FREQUENCIES (BETA AND ESPECIALLY GAMMA) IN ALL CONDITIONS BUT GREATLY EXPANDED DURING MEDITATION PRACTICE. ACROSS ALL CONDITIONS (MEDITATION AND NON-MEDITATION) DIFFERENCES WERE GREATEST IN THE SAME REGIONS: R INSULA, R INFERIOR FRONTAL GYRUS AND R ANTERIOR TEMPORAL LOBE. DISTINCT R CORE NETWORKS WERE IDENTIFIED IN ALPHA1 (8-10 HZ) AND GAMMA (25-42 HZ) BANDS, RESPECTIVELY. THE VOXELS RECRUITED TO THESE NETWORKS GREATLY EXPANDED DURING MEDITATION PRACTICE TO INCLUDE HOMOLOGOUS REGIONS OF THE LEFT HEMISPHERE.

METHODS: WE PRESENT PROTOCOL MODIFICATIONS TO PIVOT A MULTISITE RANDOMIZED CONTROLLED TRIAL STUDY, CONDUCTED AT SOUTHEASTERN AND PACIFIC NORTHWESTERN VETERANS AFFAIRS HEALTH CARE SYSTEMS, FROM BEING CONDUCTED IN-PERSON TO VIRTUALLY, FOLLOWING THE ONSET OF THE COVID-19 PANDEMIC. WE MEASURED OUTCOMES OF POSTTRAUMATIC STRESS DISORDER (PTSD) SYMPTOMS AND PSYCHOPHYSIOLOGICAL MARKERS OF STRESS AMONG FEMALE VETERANS WITH PTSD SECONDARY TO MILITARY SEXUAL TRAUMA. WE COLLECTED QUALITATIVE DATA ABOUT PROVIDER AND PARTICIPANT EXPERIENCES WITH TELEHEALTH. RESULTS: ACROSS SITES, 200 PARTICIPANTS WERE CONSENTED (48 VIRTUALLY), 132 WERE RANDOMIZED (28 TO VIRTUAL GROUPS), AND 117 COMPLETED DATA COLLECTION AND TREATMENT (69 COMPLETED ALL OR SOME DATA COLLECTION OR TREATMENT VIRTUALLY). CONCLUSIONS: THE PIVOTS MADE FOR THIS STUDY WERE IN RESPONSE TO THE COVID-19 PANDEMIC AND OFFER INNOVATIVE PROCEDURES LEVERAGING TECHNOLOGY AND CONTRIBUTING TO THE BROADER LANDSCAPE OF CONDUCTING RESEARCH VIRTUALLY.

11 1913  27 ROLE OF BREATHING EXERCISES IN ASTHMA-YOGA AND PRANAYAMA. ASTHMA IS A CHRONIC AIRWAY INFLAMMATORY DISEASE THAT RESULTS FROM A COMPLEX INTERPLAY OF GENETIC, ENVIRONMENTAL, AND LIFESTYLE FACTORS. THERE IS NO CURE FOR ASTHMA, AND THE MANAGEMENT IS USUALLY AS PER PUBLISHED GUIDELINES. AS IN MANY CHRONIC DISEASES CONDITIONS, VARIOUS ALTERNATIVE OR COMPLIMENTARY THERAPIES HAVE BEEN TRIED. OF THESE, YOGA AND PRANAYAMA HAVE GAINED WIDER ATTENTION IN RECENT YEARS. WHILE THE TERM YOGA IS A COMPLEX TERM ENCOMPASSING EIGHT LIMBS AS PER PATAMJAI IN THE YOGA SUTRAS, IN SIMPLE TERMS, YOGA IS DESCRIBED AS A COMBINATION OF 'ASANA' (PHYSICAL EXERCISES) AND 'PRANAYAMA' (BREATHING EXERCISE). THE TERM "ASTHMA" HAS BEEN DERIVED FROM THE GREEK WORD "PANTING,", WHICH INDICATES A RAPID AND SHALLOW BREATHING. THE MAIN AIM OF YOGA AND PRANAYAMA IN ASTHMA IS TO SYNCHRONIZE AND CONTROL BREATHING, THUS DECREASING HYPERVENTILATION. BESIDES THIS, THEY ALSO DECREASE THE STRESS/STRAIN/ANXIETY, CHANGE IN BEHAVIOR, BOOST IMMUNITY, AND IMPROVE STRENGTH/ENDURANCE OF RESPIRATORY MUSCLES THAT ARE HELPFUL IN ANY SUBJECT WITH ASTHMA. THERE HAVE BEEN A GOOD NUMBER OF STUDIES INCLUDING CLINICAL TRIALS IN CHILDREN WITH ASTHMA THAT HAVE FOUND SOME BENEFICIAL EFFECTS. IN THE PRESENT REVIEW, THE PHYSIOLOGY OF YOGA AND PRANAYAMA, RATIONALE FOR THEIR USE IN CHILDREN WITH ASTHMA ALONG WITH A SUMMARY OF VARIOUS STUDIES CONDUCTED TILL DATE, HAVE BEEN DISCUSSED. THESE ARE FOLLOWED BY RECOMMENDATIONS REGARDING THEIR INCORPORATION IN THE STANDARD OF CARE OF CHILDREN WITH ASTHMA.	2022	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
12 1605  45 MENTAL STRESS: NEUROPHYSIOLOGY AND ITS REGULATION BY SUDARSHAN KRIYA YOGA. AIM: THE PRESENT STUDY FOCUSES ON ANALYZING THE EFFECTS OF SUDARSHAN KRIYA YOGA (SKY) ON EEG AS WELL AS ECG SIGNALS FOR STRESS REGULATION. TO ENVISION THE REGULATION OF STRESS DETERMINATION TEST (DT) HAS BEEN USED. WE HAVE CHOSEN A CONTROL GROUP FOR CONTRIVING A COGENT COMPARISON THAT COULD BE CORROBORATED USING STATISTICAL TESTS. SUBJECTS AND METHODS: A TOTAL OF 20 SUBJECTS WERE TAKEN IN THE STUDY, OF WHICH 10 WERE ALLOTTED TO A CONTROL GROUP. ELECTROENCEPHALOGRAPH WAS TAKEN DURING A DT TASK, BEFORE AND AFTER SKY THE SKY SESSION WITH 30 DAYS OF SKY SESSION GIVEN TO THE EXPERIMENTAL GROUP. NO SKY WAS GIVEN TO THE CONTROL GROUP. RESULTS: WE QUANTIFIED MENTAL STRESS USING EEG, ECG AND DT SYNERGISTICALLY AND USED SKY TO REGULATE IT. WE OBSERVED THAT ALPHA BAND POWER DECREASES IN THE FRONTAL LOBE OF THE BRAIN WITH INCREASING MENTAL STRESS WHILE FRONTAL BRAIN ASYMMETRY DECREASES WITH INCREASING STRESS TOLERANCE. CONCLUSIONS: THESE EEG, ECG AND DT SHOWS A SIGNIFICANT DECREMENT IN MENTAL STRESS AND IMPROVEMENT IN COGNITIVE PERFORMANCE AFTER SKY, INDICATING SKY AS A GOOD ALTERNATIVE OF MEDICATION FOR STRESS MANAGEMENT.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
13 2669  32 YOGA IN MALE SEXUAL FUNCTIONING: A NONCOMPARARIVE PILOT STUDY. INTRODUCTION: YOGA IS PRACTICED BOTH IN DEVELOPING AND DEVELOPED COUNTRIES. MANY PATIENTS AND YOGA PROTAGONISTS CLAIM THAT IT IS USEFUL IN IMPROVING SEXUAL FUNCTIONS AND TREATING SEXUAL DISORDERS. AIM: WE WANTED TO STUDY THE EFFECT OF YOGA ON MALE SEXUAL FUNCTIONING. METHODS: WE STUDIED 65 MALES (AGE RANGE= 24-60 YEARS, AVERAGE AGE=40+/-8.26 YEARS) WHO WERE ENROLLED IN A YOGA CAMP AND ADMINISTERED A KNOWN QUESTIONNAIRE, I.E., MALE SEXUAL QUOTIENT (MSQ) BEFORE AND AFTER 12 WEEKS SESSION OF YOGA. MAIN OUTCOME MEASURES: MSQ SCORES BEFORE AND AFTER YOGA SESSIONS. RESULTS: IT WAS FOUND THAT AFTER THE COMPLETION OF YOGA SESSIONS, THE SEXUAL FUNCTIONS SCORES WERE SIGNIFICANTLY IMPROVED (P<0.0001). THE IMPROVEMENT OCCURRED IN SCORES OF ALL THE DOMAINS OF SEXUAL FUNCTIONS AS STUDIED BY MSQ (DESIRE, INTERCOURSE SATISFACTION, PERFORMANCE, CONFIDENCE, PARTNER SYNCHRONIZATION, ERECTION, EJACULATORY CONTROL, ORGASM). CONCLUSIONS: YOGA APPEARS TO BE AN EFFECTIVE METHOD OF IMPROVING ALL DOMAINS OF SEXUAL FUNCTIONS IN MEN AS STUDIED BY MSQ.	2010	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
14 1836  25 PSYCHOPHYSIOLOGICAL CORRELATES OF THE PRACTICE OF TANTRIC YOGA MEDITATION. AUTONOMIC AND ELECTROENCEPHALOGRAPHIC (EEG) CORRELATES OF TANTRIC YOGA MEDITATION WERE STUDIED IN THREE GROUPS OF SUBJECTS AS THEY PROGRESSED FROM NORMAL CONSCIOUSNESS INTO MEDITATION. GROUPS DIFFERED IN THEIR LEVEL OF MEDITATION PROFICIENCY. MEASURES OF SKIN RESISTANCE, HEART RATE, RESPIRATION, AUTONOMIC ORIENTING RESPONSES, RESTING EEG, EEG ALPHA AND THETA FREQUENCIES, SLEEP-SCORED EEG, AVERAGED EVOKED RESPONSES, AND SUBJECTIVE EXPERIENCE WERE EMPLOYED. UNLIKE MOST PREVIOUSLY REPORTED MEDITATION STUDIES, PROFICIENT MEDITATORS DEMONSTRATED INCREASED AUTONOMIC ACTIVATION DURING MEDITATION WHILE UNEXPERIENCED MEDITATORS DEMONSTRATED AUTONOMIC RELAXATION. DURING MEDITATION, PROFICIENT MEDITATORS DEMONSTRATED INCREASED ALPHA AND THETA POWER, MINIMAL EVIDENCE OF EEG-DEFINED SLEEP, AND DECREASED AUTONOMIC ORIENTING TO EXTERNAL STIMULATION. AN EPISODE OF SUDDEN AUTONOMIC ACTIVATION WAS OBSERVED THAT WAS CHARACTERIZED BY THE MEDITATOR AS AN APPROACH TO THE YOGIC ECSTATIC STATE OF INTENSE CONCENTRATION. THESE FINDINGS CHALLENGE THE CURRENT "RELAXATION" MODEL OF MEDITATIVE STATES.	1978	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
15  322  25 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	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                           
16  690  26 EFFECT OF COMBINED YOGA AND TRANSCRANIAL DIRECT CURRENT STIMULATION INTERVENTION ON WORKING MEMORY AND MINDFULNESS. TRANSCRANIAL DIRECT STIMULATION, A NON-INVASIVE NEUROSTIMULATION TECHNIQUE FOR MODULATING CORTICAL EXCITABILITY, AND YOGA HAVE BOTH RESPECTIVELY BEEN SHOWN TO POSITIVELY AFFECT COGNITION. WHILE PRELIMINARY RESEARCH HAS SHOWN THAT COMBINED TRANSCRANIAL DIRECT STIMULATION AND MEDITATION MAY HAVE SYNERGISTIC EFFECTS ON MOOD AND COGNITION, THIS WAS THE FIRST STUDY TO EXPLORE THE COMBINATION OF TRANSCRANIAL DIRECT STIMULATION AND YOGA. TWENTY-TWO HEALTHY VOLUNTEERS WITH A REGULAR YOGA PRACTICE WERE RANDOMIZED TO RECEIVE EITHER ACTIVE TRANSCRANIAL DIRECT STIMULATION (ANODAL LEFT, CATHODAL RIGHT DORSOLATERAL PREFRONTAL CORTEX) FOLLOWED BY YOGA INTERVENTION OR SHAM TRANSCRANIAL DIRECT STIMULATION FOLLOWED BY YOGA INTERVENTION A DOUBLE-BLIND, CROSS-OVER DESIGN OVER TWO SEPARATE INTERVENTION DAYS. OUTCOME MEASURES INCLUDED WORKING MEMORY PERFORMANCE, MEASURED WITH THE N-BACK TASK AND MINDFULNESS STATE, MEASURED WITH THE TORONTO MINDFULNESS SCALE, AND WERE CONDUCTED OFFLINE, WITH PRE-POST ASSESSMENTS. TWENTY PARTICIPANTS COMPLETED BOTH DAYS OF THE INTERVENTION. ACTIVE TRANSCRANIAL DIRECT STIMULATION DID NOT HAVE A SIGNIFICANT EFFECT ON WORKING MEMORY OR LEVELS OF MINDFULNESS. THERE WAS A SIGNIFICANT PLACEBO EFFECT, WITH BETTER PERFORMANCE ON DAY 1 OF THE INTERVENTION, IRRESPECTIVE OF WHETHER PARTICIPANTS RECEIVED ACTIVE OR SHAM TRANSCRANIAL DIRECT STIMULATION. THERE WAS NO SIGNIFICANT DIFFERENCE BETWEEN ACTIVE VERSUS SHAM TRANSCRANIAL DIRECT STIMULATION CONCERNING WORKING MEMORY PERFORMANCE AND MINDFULNESS, WHICH MAY BE ACCOUNTED BY THE SMALL SAMPLE SIZE, THE TRANSIENT NATURE OF THE INTERVENTION, THE FACT THAT YOGA AND TRANSCRANIAL DIRECT STIMULATION CONCERNING WERE NOT CONDUCTED SIMULTANEOUSLY, AND THE SPECIFIC SITE OF STIMULATION.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                 
17 2308  32 TRANSCRANIAL DIRECT CURRENT STIMULATION AND YOGA FOR FUNCTIONAL MOVEMENT DISORDERS. BACKGROUND: FUNCTIONAL MOVEMENT DISORDER (FMD), A CONVERSION DISORDER CHARACTERIZED BY INVOLUNTARY MOVEMENTS, IS DIFFICULT TO TREAT. METHODS: WE AIMED TO ASSESS THE EFFECTS OF ANODAL TRANSCRANIAL DIRECT CURRENT STIMULATION (TDCS) AND YOGA IN FMD PATIENTS (N=5). TDCS OF THE RIGHT TEMPOROPARIETAL JUNCTION, A BRAIN REGION RELEVANT IN THE SENSE OF SELF-AGENCY, WAS CONDUCTED. SUBJECTS UNDERWENT BOTH SHAM AND ANODAL TDCS WITH A WASHOUT PERIOD OF 3 WEEKS. YOGA WAS USED AS A MODE OF EXERCISE, AS WELL AS IN CONJUNCTION WITH STIMULATION TO SUSTAIN POTENTIAL CHANGES IN NEURAL PLASTICITY. RESULTS: A TOTAL OF 5 SUBJECTS COMPLETED THE STUDY [MEAN AGE: 52 (SE: 4) Y, DISEASE DURATION: 5 (SE: 1.6) Y], UNDERGOING BOTH SHAM AND ANODAL TDCS. ANODAL TDCS DOES NOT APPEAR TO BE SUPERIOR TO SHAM TDCS IN ALLEVIATING SYMPTOMS AND DISABILITY, BUT COMBINING TDCS AND YOGA APPEARS TO LEAD TO MILD IMPROVEMENT NOTED ON CLINICAL OBSERVATION, BASED ON THE CHANGE IN THE EFFICACY INDEX OF CLINICAL GLOBAL IMPRESSION FOUND IN 4 SUBJECTS. CONCLUSION: OUR STUDY RESULTS SUGGEST THAT ANODAL TDCS IS NOT SUPERIOR TO SHAM TDCS IN ALLEVIATING SUBJECTIVE SYMPTOMS AND DISABILITY IN FMD. HOWEVER, INTERPRETATION OF THESE RESULTS IS LIMITED DUE TO THE SMALL NUMBER OF STIMULATION SESSIONS AND NUMBER OF SUBJECTS. FUTURE STUDIES USING MORE FREQUENT STIMULATION SESSIONS ARE NEEDED TO FURTHER DETERMINE WHETHER ANODAL TDCS MAY HAVE A THERAPEUTIC EFFECT IN THIS PATIENT GROUP COMPARED WITH SHAM TDCS.	2021	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              
18 1288  31 GREATER CORTICAL THICKNESS IN ELDERLY FEMALE YOGA PRACTITIONERS-A CROSS-SECTIONAL STUDY. YOGA, A MIND-BODY ACTIVITY THAT REQUIRES ATTENTIONAL ENGAGEMENT, HAS BEEN ASSOCIATED WITH POSITIVE CHANGES IN BRAIN STRUCTURE AND FUNCTION, ESPECIALLY IN AREAS RELATED TO AWARENESS, ATTENTION, EXECUTIVE FUNCTIONS AND MEMORY. NORMAL AGING, ON THE OTHER HAND, HAS ALSO BEEN ASSOCIATED WITH STRUCTURAL AND FUNCTIONAL BRAIN CHANGES, BUT THESE GENERALLY INVOLVE DECREASED COGNITIVE FUNCTIONS. THE AIM OF THIS CROSS-SECTIONAL STUDY WAS TO COMPARE BRAIN CORTICAL THICKNESS (CT) IN ELDERLY YOGA PRACTITIONERS AND A GROUP OF AGE-MATCHED HEALTHY NON-PRACTITIONERS. WE TESTED 21 OLDER WOMEN WHO HAD PRACTICED HATHA YOGA FOR AT LEAST 8 YEARS AND 21 WOMEN NAIVE TO YOGA, MEDITATION OR ANY MIND-BODY INTERVENTIONS WHO WERE MATCHED TO THE FIRST GROUP IN AGE, YEARS OF FORMAL EDUCATION AND PHYSICAL ACTIVITY LEVEL. A T1-WEIGHTED MPRAGE SEQUENCE WAS ACQUIRED FOR EACH PARTICIPANT. YOGA PRACTITIONERS SHOWED SIGNIFICANTLY GREATER CT IN A LEFT PREFRONTAL LOBE CLUSTER, WHICH INCLUDED PORTIONS OF THE LATERAL MIDDLE FRONTAL GYRUS, ANTERIOR SUPERIOR FRONTAL GYRUS AND DORSAL SUPERIOR FRONTAL GYRUS. WE FOUND GREATER CT IN THE LEFT PREFRONTAL CORTEX OF HEALTHY ELDERLY WOMEN WHO TRAINED YOGA FOR A MINIMUM OF 8 YEARS COMPARED WITH WOMEN IN THE CONTROL GROUP.	2017	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               
19  455  37 CHANGES IN NEURAL CONNECTIVITY AND MEMORY FOLLOWING A YOGA INTERVENTION FOR OLDER ADULTS: A PILOT STUDY. BACKGROUND: NO STUDY HAS EXPLORED THE EFFECT OF YOGA ON COGNITIVE DECLINE AND RESTING-STATE FUNCTIONAL CONNECTIVITY. OBJECTIVES: THIS STUDY EXPLORED THE RELATIONSHIP BETWEEN PERFORMANCE ON MEMORY TESTS AND RESTING-STATE FUNCTIONAL CONNECTIVITY BEFORE AND AFTER A YOGA INTERVENTION VERSUS ACTIVE CONTROL FOR SUBJECTS WITH MILD COGNITIVE IMPAIRMENT (MCI). METHODS: PARTICIPANTS ( >/= 55 Y) WITH MCI WERE RANDOMIZED TO RECEIVE A YOGA INTERVENTION OR ACTIVE "GOLD-STANDARD" CONTROL (I.E., MEMORY ENHANCEMENT TRAINING (MET)) FOR 12 WEEKS. RESTING-STATE FUNCTIONAL MAGNETIC RESONANCE IMAGING WAS USED TO MAP CORRELATIONS BETWEEN BRAIN NETWORKS AND MEMORY PERFORMANCE CHANGES OVER TIME. DEFAULT MODE NETWORKS (DMN), LANGUAGE AND SUPERIOR PARIETAL NETWORKS WERE CHOSEN AS NETWORKS OF INTEREST TO ANALYZE THE ASSOCIATION WITH CHANGES IN VERBAL AND VISUOSPATIAL MEMORY PERFORMANCE. RESULTS: FOURTEEN YOGA AND 11 MET PARTICIPANTS COMPLETED THE STUDY. THE YOGA GROUP DEMONSTRATED A STATISTICALLY SIGNIFICANT IMPROVEMENT IN DEPRESSION AND VISUOSPATIAL MEMORY. WE OBSERVED IMPROVED VERBAL MEMORY PERFORMANCE CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE DMN AND FRONTAL MEDIAL CORTEX, PREGENUAL ANTERIOR CINGULATE CORTEX, RIGHT MIDDLE FRONTAL CORTEX, POSTERIOR CINGULATE CORTEX, AND LEFT LATERAL OCCIPITAL CORTEX. IMPROVED VERBAL MEMORY PERFORMANCE POSITIVELY CORRELATED WITH INCREASED CONNECTIVITY BETWEEN THE LANGUAGE PROCESSING NETWORK AND THE LEFT INFERIOR FRONTAL GYRUS. IMPROVED VISUOSPATIAL MEMORY PERFORMANCE CORRELATED INVERSELY WITH CONNECTIVITY BETWEEN THE SUPERIOR PARIETAL NETWORK AND THE MEDIAL PARIETAL CORTEX. CONCLUSION: YOGA MAY BE AS EFFECTIVE AS MET IN IMPROVING FUNCTIONAL CONNECTIVITY IN RELATION TO VERBAL MEMORY PERFORMANCE. THESE FINDINGS SHOULD BE CONFIRMED IN LARGER PROSPECTIVE STUDIES.	2016	
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                      
20 1321  37 HEMISPHERE SPECIFIC EEG RELATED TO ALTERNATE NOSTRIL YOGA BREATHING. BACKGROUND: PREVIOUSLY, FORCED UNILATERAL NOSTRIL BREATHING WAS ASSOCIATED WITH IPSILATERAL, OR CONTRALATERAL CEREBRAL HEMISPHERE CHANGES, OR NO CHANGE. HENCE IT WAS INCONCLUSIVE. THE PRESENT STUDY WAS CONDUCTED ON 13 NORMAL HEALTHY PARTICIPANTS TO DETERMINE THE EFFECTS OF ALTERNATE NOSTRIL YOGA BREATHING ON (A) CEREBRAL HEMISPHERE ASYMMETRY, AND (B) CHANGES IN THE STANDARD EEG BANDS. METHODS: PARTICIPANTS WERE RANDOMLY ALLOCATED TO THREE SESSIONS (A) ALTERNATE NOSTRIL YOGA BREATHING (ANYB), (B) BREATH AWARENESS AND (C) QUIET SITTING, ON SEPARATE DAYS. EEG WAS RECORDED FROM BILATERALLY SYMMETRICAL SITES (FP1, FP2, C3, C4, O1 AND O2). ALL SITES WERE REFERENCED TO THE IPSILATERAL EAR LOBE. RESULTS: THERE WAS NO CHANGE IN CEREBRAL HEMISPHERE SYMMETRY. THE RELATIVE POWER IN THE THETA BAND WAS DECREASED DURING ALTERNATE NOSTRIL YOGA BREATHING (ANYB) AND THE BETA AMPLITUDE WAS LOWER AFTER ANYB. DURING QUIET SITTING THE RELATIVE POWER IN THE BETA BAND INCREASED, WHILE THE AMPLITUDE OF THE ALPHA BAND REDUCED. CONCLUSION: THE RESULTS SUGGEST THAT ANYB WAS ASSOCIATED WITH GREATER CALMNESS, WHEREAS QUIET SITTING WITHOUT SPECIFIC DIRECTIONS WAS ASSOCIATED WITH AROUSAL. THE RESULTS IMPLY A POSSIBLE USE OF ANYB FOR STRESS AND ANXIETY REDUCTION.	2017
