Evaluating the effect of single auriculotherapy point for large intestine among indivisuals with functional constipation - A randomized control trial
(S-VYASA, 2026-05-13) Shaik Saba Banu; Kavana.G; Moulya K Appanna; Pallavi V
BACKGROUND:
Functional constipation is one of the most common gastrointestinal disorders affecting young adults and university students due to poor dietary habits, low fiber intake, inadequate hydration, stress, sedentary lifestyle, and irregular bowel habits. It is characterized by infrequent bowel movements, hard stools, straining during defecation, abdominal bloating, and a feeling of incomplete evacuation. Although conventional management such as laxatives and dietary modifications provides temporary relief, prolonged use may cause side effects including bloating, abdominal cramps, and dependency. Therefore, there is an increasing need for safe, simple, and non-invasive complementary therapies. Auriculotherapy, a branch of Traditional Chinese Medicine (TCM), is based on stimulation of specific auricular points corresponding to internal organs and body systems. The Large Intestine auricular point is believed to regulate intestinal motility, improve bowel function, and restore the flow of Qi, thereby relieving constipation symptoms.
AIM:
To evaluate the effectiveness of single-point auriculotherapy at the Large Intestine auricular point in improving symptoms of functional constipation among young adults.
METHODS:
This randomized controlled trial included 60 participants aged between 18 and 25 years diagnosed with functional constipation. Participants were randomly divided into two groups: Experimental Group (Group A) and Control Group (Group B), with 30 participants in each group. The experimental group received press needle auriculotherapy at the Large Intestine auricular point, while the control group received sham auriculotherapy using adhesive plaster without active stimulation. The intervention was administered three sessions per week for four weeks. Baseline assessments were recorded before the intervention, and post-intervention assessments were conducted after completion of the four-week treatment period.
ASSESSMENT:
Bowel function and constipation severity were assessed using standardized outcome measures. Bowel movement frequency was evaluated using a daily Bowel Diary. Constipation severity was assessed using the Constipation Assessment Scale (CAS), which included symptoms such as abdominal bloating, hard stool, straining, rectal fullness, and incomplete evacuation. Abdominal discomfort and symptom severity were measured using the Visual Analogue Scale (VAS), with scores ranging from 0 to 10.
RESULTS:
The study demonstrated significant improvement in constipation symptoms following single-point auriculotherapy intervention. CAS scores and bowel movement frequency showed highly significant improvement after four weeks of intervention (p < 0.001), indicating reduced constipation severity and improved bowel habits. The experimental group showed better clinical improvement compared to the control group. VAS scores showed mild improvement in abdominal discomfort, although the changes were not statistically significant. The observed improvement may be associated with activation of the vagus nerve and autonomic nervous system modulation, which enhances intestinal motility and colon peristalsis.
CONCLUSION:
Single-point auriculotherapy at the Large Intestine auricular point may serve as a safe, simple, cost-effective, and non-invasive complementary therapy for managing functional constipation among young adults. The findings suggest that auriculotherapy effectively improves bowel movement frequency and reduces constipation severity, thereby contributing to better bowel health and quality of life. Further studies with larger sample sizes and longer follow-up periods are recommended to establish long-term effectiveness and broader clinical applicability.

Evaluating neural activation changes following figure of eight walk training in parkinson's disease using fNIRS Pre-post observational study
(S-VYASA, 2026-05-13) Tejaswini R; T Srujana; Sharad Shivajirao Chaudhari; Krishna Dwivedhi; Arundathi Goley
Background: Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by impaired motor control, particularly during complex gait activities. Figure-of-eight walking (infinity walk) is a dynamic locomotor task that challenges balance, coordination, and motor planning. Functional near-infrared spectroscopy (fNIRS) enables real-time assessment of cortical hemodynamic responses during such functional movements.
Objective: To evaluate the immediate effect of figure-of-eight walking on cortical activation, measured through changes in oxygenated (HbO) and deoxygenated hemoglobin (HbR), in individuals with Parkinson’s disease.
Methods: A single-group, within-subject experimental study was conducted on 11 participants diagnosed with Parkinson’s disease. Baseline cortical activity was recorded using fNIRS during rest, followed by recording during and after the figure-of-eight walking task. Hemodynamic parameters including HbO, HbR, and total hemoglobin were analyzed. Normality of data was assessed using the Shapiro–Wilk test, and paired sample t-tests were applied to compare pre- and post-intervention values.
Results: All variables were normally distributed (p > 0.05). Paired t-test analysis revealed no statistically significant differences between pre- and post-intervention values for HbO (p = 0.378), HbR (p = 0.397), and total hemoglobin (p = 0.627). Effect size analysis indicated small effect sizes across all variables. However, qualitative observation of fNIRS topographical maps demonstrated increased and more symmetrical cortical activation patterns following the intervention.
Conclusion: Figure-of-eight walking did not produce statistically significant changes in cortical hemodynamics in this sample. However, observed trends in cortical activation suggest potential neural engagement and compensatory cortical recruitment. Further studies with larger sample sizes and longer intervention durations are recommended to better elucidate the neurophysiological effects of complex gait training in Parkinson’s disease.

Effect of cyclic meditation on changes of Iris and perceived stress among college going students: A pilot observational study
(S-VYASA, 2026-05-13) Lavanya M. R.; Titty George
BACKGROUND:
Stress has been defined as a state of mental or emotional strain due to adverse or challenging circumstances. (Agyapong et al., 2023)The ability to adapt to stress is crucial for maintaining homeostasis and, consequently, for sustaining life.(Chaves et al., 2021).The rising incidence of stress-related disorders highlights the necessity for further research into stress adaptation, there are two primary regulatory pathways: the hypothalamic-pituitary-adrenocortical axis and the sympathetic-adrenomedullary axis. These pathways work together, supported by the significant bidirectional connections between their respective centers, the paraventricular nucleus of the hypothalamus (PVN), and the brainstem monoaminergic cell groups. The PVN, particularly its corticotropin-releasing hormone (CRH) producing neurons, is regarded as the central hub for stress regulation.(Chaves et al., 2021)
AIM:
• To assess the impact of 'Cyclic Meditation' practice on iris changes and perceived stress among college students.
OBJECTIVE: The objective of the study is:
• To study the effect of cyclic meditation on the iris.
• To study the effect of cyclic meditation on perceived stress
• To evaluate the common changes in iris pattern in stressed individuals.
MATERIALS AND METHODS:
Participants:
College going students of age 18 to 25 years. The proposed study was a Pilot observational study with a total of 34 subjects who were pre assessed and selected.
Design:
A total of 34 subjects were screened and sample were based on inclusion and exclusion criteria. before the intervention consent form is taken.
Assessments:
• Iris parameters
• Perceived Stress Scale (PSS)
Intervention:
• Yoga- Cyclic Meditation will be given as intervention daily one time for about 30minutes duration for 60 days.
RESULTS:
There is statistically significant difference between pre data and post data which suggests that yogic cyclic meditation is effective. Significant improvement was seen in PSS scoring and P value (less than 0.05)
CONCLUSION:
Cyclic Meditation has an effect on stress rings in the iris, as well as a reduction in perceived stress levels measured by the PSS-10 questionnaire and is effective in improving quality of life and reducing stress in individuals.

Glycemic and physiological responses in healthy adults following 1008 surya namaskar: A time dependent pre-post CGM study.
(S-VYASA, 2026-05-13) Nandini Priya; Dasari Navya Sindhuri; H. R. Nagendra; Sharad Shivajirao Chaudhari
Background:
Surya Namaskar is a classical yogic practice integrating physical movement, breath regulation, and metabolic activation. While its general health benefits are known, the acute glycemic and physiological responses to performing 1008 Surya Namaskar remain underexplored, particularly using continuous glucose monitoring (CGM).
Aim:
To evaluate the time-dependent glycemic variability and physiological responses in healthy adults following the performance of 1008 Surya Namaskar using continuous glucose monitoring (CGM) and pre– and post–assessment.
Methods:
A pre–post experimental study was conducted on 52 healthy adults. CGM readings were recorded at nine break intervals during the session. Pre- and post-intervention parameters included random blood glucose (GRBS), blood pressure (SBP, DBP), oxygen saturation (SpO₂), body weight, and breath-holding capacity (Kumbhaka). Repeated measures analysis with appropriate corrections was used to evaluate changes across time points, along with paired and non-parametric tests for pre–post comparisons.
Assessment:
Continuous glucose monitoring was performed at nine break intervals, along with pre and post–measurements of random blood glucose, blood pressure, oxygen saturation (SpO₂), body weight, and breath-holding capacity (Kumbhaka).
Results:
A significant variation in glucose levels was observed across the nine break intervals, demonstrating marked glycemic variability during the session. The CGM revealed a biphasic pattern, with an initial decline followed by a progressive rise, reaching peak levels toward the final phase. Pre–post analysis showed an increase in blood glucose levels along with improvements in oxygen saturation and breath-holding capacity. A measurable change in body weight was also observed following the session.
Conclusion:
The 1008 Surya Namaskar induces significant time-dependent glycemic fluctuations and acute physiological adaptations in healthy individuals. The biphasic glucose response reflects enhanced metabolic activity, involving increased peripheral utilization followed by compensatory glucose mobilization. These findings highlight Surya Namaskar as a potent metabolic stimulus influencing glucose regulation and respiratory efficiency.

Effects of Bhagavad Gita shloka chanting on autonomic and cognitive functions in college students
(S-VYASA, 2026-05-13) Mithra Raja; Puja Kumari Mandal; Sridevi K. J.; Krishna Dwivedi
Background:
Bhagavad Gita chanting is a traditional yogic practice involving rhythmic recitation, controlled breathing, focused attention, and memorization. Previous studies on mantra chanting have demonstrated beneficial effects on autonomic regulation, cognitive abilities, and emotional well-being through modulation of the autonomic nervous system and Heart Rate Variability (HRV). Bhagavad Gita shlokas are traditionally believed to enhance mental clarity, concentration, and inner stability. However, limited scientific evidence exists regarding the effects of structured Bhagavad Gita shloka chanting and memorization on autonomic functions, cognitive abilities, and anxiety among young adults.
Aim:
To explore the effect of chanting and memorizing the Bhagavad Gita Shlokas on autonomic and cognitive functions (Attention and Mindfulness) in college students.
Objective:
1. To explore the effect of an 8-week Bhagavad Gita shloka chanting on autonomic nervous system functioning using HRV as a biomarker.
2. To explore the effect of an 8-week Bhagavad Gita shloka chanting on cognitive abilities such as attention and mindfulness.
3. To assess changes in anxiety levels before and after the 8-week of Bhagavad Gita shloka chanting.
MATERIALS AND METHODS:
Participants:
A total of 30 college-going students of the age group 18-25 years were recruited based on convenience sampling (Voluntary Participation).
Design: Participants who expressed interest in the study were first screened using the predefined inclusion and exclusion criteria. Thirty eligible participants were selected, after which written informed consent was obtained prior to participation.
Assessments:
Baseline assessments included Heart Rate Variability parameters such as RMSSD, SDNN, HF, LF, and LF/HF ratio, along with cognitive and psychological assessments using the Six Letter Cancellation Task (SLCT), Mindfulness Attention Awareness Scale (MAAS), and State-Trait Anxiety Inventory Form Y-2 (STAI-Y2). Post-intervention assessments were conducted following completion of the intervention.
Intervention:
The intervention consisted of chanting and memorizing 20 shlokas from the Bhakti Yoga chapter of the Bhagavad Gita, divided into four padas for systematic learning, practiced for 30 minutes daily, 6 days a week, for 8 weeks, with the first 20 days focused on learning along with chanting and the remaining period dedicated to revision and memorization.
Results:
Statistically significant changes were observed in cognitive assessments, including mindfulness and attention, as well as in HRV parameters such as SDNN, LF, and LF/HF ratio following the intervention. However, RMSSD, HF, and anxiety scores did not show significant changes.
Conclusion:
The findings support chanting as a simple and effective mind–body intervention; however, further studies with larger sample sizes, longer intervention duration, and controlled designs are required to validate and generalize these results.
