Item EFFECT OF INTEGRATED YOGA IN NURSING PROFESSIONALS WITH CHRONIC LOW BACK PAIN – A RANDOMIZED CONTROL TRIAL(S-VYASA, 2018-11) PATIL, NEETINAKUMAR; Tekur, Padmini; Nagendra, H. R.; Monohar, P.V.Background: Chronic Low back pain (CLBP) adversely affects health-related quality of life in nursing professionals. Yoga has positive impact on LBP. Studies assessing the effects of Yoga on CLBP in nursing population are lacking. Aim: Present study is conducted to evaluate and compare the effect of integrated Yoga and physical exercises on pain, disability, psychological parameters and quality of life in nurses with CLBP. Methods: It is a prospective randomized control trail.88 female nursing professionals of age 33.77±3.44 years from a tertiary care hospital of South India were randomized in to yoga group (YG) (n=44; 31.45 ± 3.47 years) and control [exercise] group (CG) (n=44; 32.75 ± 3.71). YG was intervened with Integrated Yoga Therapy Module (IYTM) practices, one hour per day, five days week for six weeks. CG practiced a set of physical exercises for the same duration. All subjects were assessed using Numerical Rating Scale (NRS) for pain, Roland Morris Disability Questionnaire (RMDQ) for functional disability, Fear Avoidance Belief Questionnaire- physical (FABQpa), Fear Avoidance Belief Questionnaire - work (FABQw), State and Trait Anxiety Inventory (STAI), Beck’s Depression Inventory (BDI), and Perceived Stress Scale (PSS), Heart Rate Variability (HRV) [low frequency (LF), high frequency (HF), LF/HF ratio] and WHO quality of life questionnaire (WHOQOL-BREF) at baseline and end of six week intervention. Data were analyzed by paired samples t test and independent samples t test for within group and between group comparisons respectively by using SPSS version 22. Results: After six weeks of Yoga intervention, we found a significant decrease in NRS (p<0.001), RMDQ (p<0.001), FABQpa (p<0.001), FABQw (p<0.001), State Anxiety (p<0.001), Trait Anxiety (p<0.001), BDI (p<0.001), and PSS (p<0.001), LF/ HF ratio (p<0.001), WHOQOL-BREF [Physical (p<0.001), Psychological(p<0.001), Social(p<0.001)] but did not differ statistically for HF (p=0.24) and LF (p=0.103), environmental-QoL (p=0.078) variables compared to baseline in YG. After six weeks of physical exercise intervention, there was a significant decrease in NRS (p<0.001), RMDQ (p<0.001), FABQpa (p<0.001), FABQw (p<0.001), State Anxiety (p=0.031), BDI (p<0.001), and PSS (p<0.001), WHOQOL-BREF [Physical (p<0.001), Psychological(p<0.001), Social(p<0.001)] but did not differ statistically for Trait Anxiety (p=0.29), LF (p=0.513), HF (p=0.555) and LF/HF ratio (p=0.615), environmental- QoL (p=0.0957) variables compared to baseline in CG. On comparison between groups, YG showed a significant decrease in NRS (p<0.001), RMDQ (p<0.001), FABQpa (p<0.001), FABQw (p<0.001), State Anxiety (p<0.001), Trait Anxiety (p=0.025), BDI (p<0.001), and PSS (p<0.001), LF (p=0.01), LF/ HF ratio (p<0.001), WHOQOL-BREF [Physical (p<0.001), Psychological(p<0.001), Social(p<0.001)] but did not differ statistically for in HF (p=0.32) and environmental-QoL (p=0.25) variables compared to control group for post assessment. Conclusions: Integrated Yoga intervention was found to be more beneficial in improving pain, disability, anxiety, stress, fear avoidance, heart rate variability and quality of life among nursing professionals with chronic low back pain. There was a negative correlation between psychological parameters and quality of life at baseline.Item Empirical evidence for increased creative cognition and associated EEG Synchrony following experience of self during low default mode network activity in youth(S-VYASA, 2018) Shetkar, Reshma M.; Hankey, Alex; Nagendra, H. R.Background: Western science divides the creative process into four stages: preparation, incubation, illumination and verification. The scientific study of creativity now focuses on brain function studying how different brain regions are involved, suggesting that process depends on coordinated use of the frontal, parietal and temporal lobes of the brain. Brain studies indicate that EEG coherence is a bio-marker signature, suggesting that creativity involves increased integration between different brain regions. Traditional Indian approaches to understanding creativity are based on expanded states of mind described in Vedic literature. They suggest that ‘expansion of mind’ is the key step, achieved by practice of deep meditations. The disparity between the two approaches western and eastern, suggests that considering both together may bring deeper insights. Deep meditation is known to bring illumination, which is important. Brain mechanisms suggest themselves as illumination correlates with brain coherence and synchrony. Eastern wisdom may help resolve problems in the scientific approach. Eastern Literature: Certain Upaniñat, Çikñä, Yoga, and Alaìkära Çästra contain insights into the nature of creativity. The Upaniñat have deep implications for workings of the mind. Çikñä identifies four levels of speech: transcendental, ideas, linguistic thoughts, and speech. Ideas form the basis for cognition. Yoga brings access to the deepest level of consciousness Samädhi, the ‘blank’ state of mind held to be necessary for incubation; and Åtambharä Prajïä, the state where creativity arises. The works of Vyasa, Kälidäsa, and Saint Jïäneçvara, all experts in Alaìkära Çästra, offer examples of profound processes of cognition and creativity. The Upaniñat offer insights and patterns of thought that guide disciples of Masters to their own realization of illumination, and abilities to help solve humanity’s problems.Item Use of integrated approach of yoga therapy and ayurveda in the management of migraine headache(S-VYASA, 2019) Sharma, Vasudha M.; Nagendra, H. R.Background: There is a rise in the need for Complementary and Integrative medicine to provide long-term healing solutions in non-communicable diseases in general and Migraine Headache in particular. Knowing the limitations of conventional medical approach, the present study therefore evaluated the influence of the two Indian traditional systems of medicine, i.e., Ayurveda and Yoga as an integrative medical intervention. Changes following the use of Ayurveda and Yoga therapy were studied on symptoms, migraine-related disability, perceived stress, autonomic variables, muscle activity and quality of life in patients with migraine headache without aura. Aims and Objective: • To compile and understand the concept of migraine headache according to Ayurveda and Yoga texts. • To scientifically validate the use of Ayurveda and Yoga in the management of migraine headache without aura. Methodology: This study was a Prospective, Open labelled, matched control trial comparing an Ayurveda- Yoga group (AY) with a Control group (CT) on symptomatic conventional treatment. 30 subjects who were recruited to Ayurveda and Yoga (AY) group underwent traditional Pañcakarma (Bio-purification) using Virecana (therapeutic purgation) followed by Yoga therapy, while 30 subjects matched for age and gender belonging to the Control (CT) group continued on symptomatic treatment (NSAID's) for 90 days. The subjects of both groups were administered the Suśruta Prakṛti Inventory on day 1 to understand individual body constitution. A Comprehensive Headache-related Quality of life Questionnaire (CHQQ) and Visual analogue scale (VAS) were administered on day 1 and day 90 of the study. The symptom checklist, migraine disability assessment score, perceived stress, heart rate variability and surface electromyography of Frontalis muscle were measured on Day 1, Day 30 and Day 90 in both groups. Data were analysed using Repeated Measures of ANOVA followed by a post-hoc analysis with Bonferroni correction. Results: Out of the 60 subjects belonging to both groups, 46 (76.6%) had Pitta based Prakṛti either as pravara (primary) or as madhyama (secondary)). Following 90 days of intervention the AY group showed significant reduction in the migraine related symptoms viz., number of attacks, duration of each attack, associated with nausea and vomiting, severity of headache and analgesic requirements. The pain intensity reduced significantly (p<.001). There was a significant reduction in migraine disability and perceived stress scores were seen in AY group (P<.001). The low-frequency component of the heart rate variability decreased significantly, the high-frequency component increased and their ratio showed improved sympatho-vagal balance. The root mean square of the electromyography signal and integral electromyography of the frontalis muscle decreased in the AY group compared to the control group. There was a significant improvement in the total score of headache related Quality of Life (p<.001). Conclusion: An Integrated Yoga therapy and Ayurveda based intervention reduces symptoms, intensity of pain, migraine related disability and perceived stress. It also reduces the sympathetic arousal and muscle tension therefore improving the quality of life in migraine patients.Item FIELD REG STUDIES IN MYSORE DASARĀ AND SOMAYAJÑA EVENTS(S-VYASA, 2017-10) Divya, B. R.; Nagendra, H. R.The existence of the psychokinetic potential of the human consciousness through the interactions between the man and the physical systems has explored the ability of the mind to collapse the randomness of a physical system. Performance of sacrificial rituals is harmonious to all living beings of the Cosmos. The life process governed by proper combination of Agni and Soma is very well demonstrated in our Vedic Rituals such as Yāga/Homa. Chanting of mantras, ingredients, and rituals involved in Yāga have already proved the positive impact of performing Yāga on human beings, animal and plant life through many studies. The use of Soma establishes a link between the consciousness and the processes of creation. It`s ceremonies with specific herbal mixtures act medicinally on the body and psycho actively on the mind directly effecting the ontological status of a person. Yajñas and Cultural programs are a participatory act thru which human beings create and maintain their existence in the world. Harmonious company with similar focused attention are motivation towards togetherness and mutual support creating Collective Consciousness Fields.
