Effect of yam chanting with Hridaya mudra on blood pressure and Heart Rate Variability (HRV) in hypertension - A randomized control trial protocol

Abstract

Background: Primary Hypertension is a prevalent chronic condition, defined by systolic blood pressure (SBP) ≥130 mmHg and/or diastolic blood pressure (DBP) >80 mmHg. Its prevalence is approximately 4.6% in the general adult population, with a higher prevalence in Indian villages (10%). Yam chanting with Hridaya mudra is a yogic practice with potential therapeutic effects, but its impact on Primary Hypertension has not been scientifically validated. Objective: To evaluate the effect of Yam chanting with Hridaya mudra on blood pressure in individuals with Primary Hypertension. Materials and Methods: A Randomized Controlled Trial (RCT) design will be employed. Eligible participants will be randomly assigned to either the study group or the control group. The study group will practice Yam chanting with Hridaya mudra for 10 minutes daily, while the control group will rest in a lying position for the same duration, over 21 days. Pre- and post-intervention blood pressure measurements will be recorded. Data will be analyzed using SPSS version 16, with a significance level set at p
