Effect of Yoga of Adaptive Yogasana Practice on the Flexibility and Psychomotor Variables in Intellectually Disabled Subjects.

Intellectual disability (ID) is a public health challenge affecting communities worldwide. ID is characterized by impaired physical and cognitive functioning and less engaged in physical activities. The objective of this study was to assess the impact of adaptive yoga practices on cognitive and motor abilities in the subjects with ID. Sixty-six subjects with mild and moderate IDs were purposively selected and randomly divided into experimental and control groups, with 33 subjects in each group. One month of adaptive yoga module was provided to the experimental group. To assess the impact of the yoga intervention, Functional Reach Test (FRT), Wall Toss Test (WTT), Finger Tapping Test (FTT), Sit-Reach Test (SRT), and Six Letter Cancellation Test (SLCT) were administered. The experimental group showed a statistically significant improvement with P < 0.05 across all the parameters, whereas the control group could not observe a significant improvement. Based on the results, this study concludes that "one month of adaptive yoga module" delivered impact and helped to improve the dynamic balance, eye-hand coordination, neuro-motor function, spinal flexibility, and selective attention in ID-afflicted subjects.

Integrated Yoga Practice in Cardiac Rehabilitation Program: A Randomized Control Trial.

Background: Coronary artery disease (CAD) is a detrimental noncommunicable disease, which is increasing due to sedentary lifestyle and urbanization in the young population. It is further elevated with risk factors such as stress, anxiety, depression, an increase in triglycerides, dyslipidemia, hyperglycemia, hypertension, and so on, which manifests as atherosclerotic disease. Yoga-based lifestyle intervention is a noninvasive effective treatment method to control and prevent cardiac risk factors in CAD patients. Yoga has been used in India as a therapeutic method to manage hypertension and other chronic disorders and is fast gaining popularity as an effective means for the alleviation of stress, improvement of fitness, and enhancement of well-being. This study aimed to determine the feasibility of introducing the integrated approach of yoga therapy (IAYT) in a cardiac rehabilitation center in India and understand its usefulness in improving the cardiac function and managing the cardiac risk factors in acute myocardial infarction patients with left ventricular dysfunction. Methods and Design: Cardiac patients were randomized to a yoga-practicing group (n = 33) and a control group (n = 33). The yoga-practicing group was instructed to attend three supervised IAYT classes 3 days per week for 12 weeks at the hospital yoga center. The control group received standard care that included pharmacologic treatment and the instructions of the cardiologist. The outcome measures were assessed at baseline (T1 = 0) and completion (T2 = 3 months). The primary outcome measure was the left ventricular ejection fraction (LVEF). Results: There was no statistically significant difference in LVEF (U = 420.500, p value = 0.218) between the two groups. However, the yoga-practicing group showed significant reduction in depression (Cardiac Depression Scale [CDS], U = 71, p value = 0.0), anxiety (Hamilton Anxiety Rating Scale [HAM-A], U = 128, p value = 0.0), and a significant increase in quality of life (QOL) scores (Duke Activity Status Index [DASI], U = 146, p value = 0.0; and metabolic equivalents (METs), U = 136, p value = 0.0) at 3 months compared to control. Overall, the CAD patients practicing yoga showed a favorable profile compared to control individuals on CDS, HAM-A, DASI, and MET outcomes. Control and yoga practicing groups did not differ significantly in the lipid levels. Conclusion: This study indicated that the integration of yoga practice in a cardiac rehabilitation program is feasible and has no added benefit in improving the cardiac function. However, the addition of yoga to cardiac rehabilitation may be beneficial in reducing depression and anxiety and improving QOL in patients.

Development of a yoga module targeting cardiovascular health for patients with post-myocardial left ventricular dysfunction in India.

BACKGROUND: Yoga is known to contribute towards cardiovascular health. This paper describes the development of a need-based yoga program which is suitable to be integrated into the cardiac rehabilitation of post-myocardial infarction patients with left ventricular dysfunction. MATERIALS AND METHODS: Based on the assessment of the need of the patients, literature review, and expert opinion, a yoga module was developed using the qualitative method of inquiry. The program included warm-up exercises, yogic asanas, pranayama, meditation and counseling sessions. A structured questionnaire eliciting comments on the contents was given independently to ten experts working in the field of health and yoga for validation. The final module was derived after incorporating the suggestions of the experts. RESULTS: Using the raters' expertise in cardiology and yoga practice, the practices which constitute the module were optimized. Majority of the experts (raters) agreed with the duration of 1 h training for 1month under supervision as adequate for subsequent practice at home. There was a 0.786 inter-rater reliability estimated using the interclass coefficient (ICC) and 0.789 internal consistency of the questions, measured using Cronbach's alpha. Both values indicate "good" reliability and consistency of the yoga module. CONCLUSION: The developed yoga module was found to be acceptable. Future randomized control trials will be necessary to validate the effectiveness of this module and if the module demonstrates to be effective by clinical studies, it may add a therapeutic option in the rehabilitation of patients with heart failure following myocardial infarction, which can be applied in the hospitals and community level.

P300 and Heart Rate Variability Recorded Simultaneously in Meditation.

Sympathetic activation is required for attention. Separate studies have shown that meditation ( a) improves attention and ( b) reduces sympathetic activity. The present study assessed attention with the P300 and sympathetic activity with heart rate variability (HRV). Forty-seven male subjects (group mean age ± SD, 21.6 ± 3.4 years) were assessed in 4 mental states: ( a) random thinking, ( b) nonmeditative focusing, ( c) meditative focusing, and ( d) defocused meditation. These were recorded on 4 consecutive days. HRV, respiration, and P300 event-related potentials (ERPs) were recorded before and after the sessions. Data were analyzed with repeated-measures analysis of variance followed by post hoc analysis. HRV showed a significant increase in low-frequency (LF) power, decrease in high-frequency (HF) power and an increase in average heart rate based on the average R-R interval after meditative focusing, compared with before. In contrast, the average heart rate decreased after defocused meditation compared with before. There was a significant increase in the P300 peak amplitude after meditative focusing and defocused meditation, with a reduction in peak latency after defocused meditation. These results suggest that after meditation with focusing, there was sympathetic arousal whereas after defocused meditation, there was a decrease in the average heart rate while participants carried out the P300 auditory oddball task sooner.

Association between a guided meditation practice, sleep and psychological well-being in type 2 diabetes mellitus patients.

Background Type 2 diabetes mellitus [T2DM] is one of the leading causes for mortality. This study examined the role of an self-awareness based guided meditation practice, Cyclic Meditation [CM] on perceived stress, anxiety, depression, sleep and quality of life in T2DM patients. Design A single arm pre-post design was used for the study. Setting The study was conducted in an auditorium for general public diagnosed with T2DM in Ernakulam, Kerala, India. Subjects Subjects were 30 T2DM patients, both male and female of age 50.12 ± 11.15 years and BMI 25.14 ± 4.37 Kg/m2 and not having a history of hospitalisation were randomly recruited for the study following advertisements in national dailies. Intervention Participants completed a supervised CM programs in the evenings, 5 days a week for 4 weeks, in addition to their regular medication. Measures Perceived stress, anxiety and depression were assessed with Perceived Stress Scale, State Anxiety Inventory and Beck's depression inventory, respectively. Sleep and quality of life were assessed with Pittsburgh Sleep Quality Index and WHO-Quality of Life - BREF respectively. Analysis Changes in the outcome measures from baseline to 4 weeks were compared using paired "t" test. Results After 4 weeks, the quality of life and sleep scores increased 7.1% [p = 0.001] and 32.7% [p = 0.001], respectively. The perceived stress, anxiety and depression reduced 26.1% [p = 0.001], 16.01% [p = 0.003] and 37.63% [p = 0.006] as compared to their baseline reports. The CM practice also reduced daytime dysfunction. Conclusions A guided self-awareness based meditation program was safe and effective in improving depression, anxiety, perceived stress and enhance sleep and quality of life in T2DM patients, which could be helpful in reducing the future complications of T2DM. Mind management is essential along with medical management to achieve better clinical results.

Yoga: Managing overweight in mid-life T2DM.

BACKGROUND: The dramatic rise in the prevalence of obesity and type 2 diabetes mellitus (T2DM) is associated with increased mortality, morbidity as well as public health care expenses worldwide. Previous research suggests that yoga holds promise for obesity and T2DM management. OBJECTIVE: The objective of the present study was to assess the effect of intensive integrated approach of yoga therapy (IAYT) on body fat and body mass index (BMI) and resting metabolism in mid-life overweight patients with T2DM (BMI, Mean ± SD, 27.05 ± 4.51). MATERIALS AND METHODS: Twenty-four mid-life patients (6 females) with T2DM (Age, Mean ± SD, 55.38 ± 7.96 years) participated in the study and practiced IAYT for 7 days. The IAYT works at five layers of human existence (physical, vital, mental, intellectual and bliss) to bring positive health. The body fat and BMI and resting metabolism were recorded before and after IAYT using Karada Scan body composition monitor HBF-375 from Omron Healthcare Singapore PTE LTD. STATISTICAL ANALYSIS: SPSS-16 was used to analyze the data. Shapiro-Wilk test showed that the data was not normally distributed. Further, the Wilcoxon signed-ranks test was used to analyze the change in means of pre- and post-measurements. RESULTS: Data analysis showed that there was a significant decrease in body fat and BMI and resting metabolism (in all assessments, P < 0.001). CONCLUSION: The present study suggests that 7 days practice of IAYT has a great promise for the management of overweight in mid-life patients with T2DM. Additional well-designed studies are needed before a strong recommendation can be made.

Prevalence of type 2 diabetes among Yoga practitioners: A pilot cross-sectional study in two districts in India.

INTRODUCTION: Diabetes is one of the major health diseases in the world today. The efficacy of Yoga in the management of type 2 diabetes is well-established. The aim of this study was to assess the prevalence of type 2 diabetes among Yoga practitioners in two districts of India (one each in West and South of India). METHODOLOGY: In this cross-sectional field study, 155 Yoga practitioners from Pune and 192 from Ernakulam districts were assessed using the diabetes risk test and fasting blood sugar. The data collected were entered in a statistics software package and analyzed using the Pearson's correlation analysis, t-test, univariate ANOVA, and linear regression to understand the predictors of risk for diabetes. RESULTS: The overall prevalence of diabetes among Yoga practitioners in Central Pune was 3.6% (95% confidence interval [CI]: [0.01-0.04]). 18.9% of participants (95% CI: [0.16-0.19]) were diagnosed to be "at risk" for diabetes. In Ernakulam, the overall prevalence of diabetes among practitioners was 26% (95% CI: [0.05-0.06]) with 12% of practitioners (95% CI: [0.05-0.06]) diagnosed to be "at risk" for diabetes (prediabetic). Higher age and lesser duration of Yoga practice were significant predictors of diabetes. CONCLUSION: It is essential for every person above the age of 40 to undergo regular health check-ups and screening for diabetes and involve oneself in lifestyle modification programs such as Yoga for significantly long duration of time on a daily basis, to better manage diabetes.

Long Latency Auditory Evoked Potentials during Meditation.

The auditory sensory pathway has been studied in meditators, using midlatency and short latency auditory evoked potentials. The present study evaluated long latency auditory evoked potentials (LLAEPs) during meditation. Sixty male participants, aged between 18 and 31 years (group mean±SD, 20.5±3.8 years), were assessed in 4 mental states based on descriptions in the traditional texts. They were (a) random thinking, (b) nonmeditative focusing, (c) meditative focusing, and (d) meditation. The order of the sessions was randomly assigned. The LLAEP components studied were P1 (40-60 ms), N1 (75-115 ms), P2 (120-180 ms), and N2 (180-280 ms). For each component, the peak amplitude and peak latency were measured from the prestimulus baseline. There was significant decrease in the peak latency of the P2 component during and after meditation (P<.001; analysis of variance and post hoc analysis with Bonferroni adjustment). The P1, P2, and N2 components showed a significant decrease in peak amplitudes during random thinking (P<.01; P<.001; P<.01, respectively) and nonmeditative focused thinking (P<.01; P<.01; P<.05, respectively). The results suggest that meditation facilitates the processing of information in the auditory association cortex, whereas the number of neurons recruited was smaller in random thinking and non-meditative focused thinking, at the level of the secondary auditory cortex, auditory association cortex and anterior cingulate cortex.
