Effect of Yoga on Quality of Life in Patients with Pulmonary Tuberculosis: A Randomized Control Trial.

Abstract

Yoga is emerging as one of the holistic approaches to respiratory diseases. The scope of yoga is expanding in communicable diseases with physical, mental, and societal benefits. The present study aims to evaluate the effect of integrated yoga as an adjuvant therapy to the National Tuberculosis Elimination Programme (NTEP) on assessing health-related Quality of Life (QoL) in patients with pulmonary tuberculosis (PTB). A randomized controlled trail study was conducted in a tertiary care teaching hospital. The study screened 826 PTB patients; 72 patients were found suitable and agreed to participate. The PTB patients were randomly assigned to either a yoga group (n = 36) or a control group (n = 36) using the sequentially numbered opaque sealed envelope technique. The control group received standard-of-care treatment as per NTEP, and the yoga group practiced 45 min of integrated yoga for 8 weeks along with standard of care. The World Health Organization Quality of Life (WHOQOL-BREF) questionnaire was used to collect the data at baseline and after 8 weeks of intervention. The results of within-group comparisons in both the groups showed that there was a significant improvement in physical (P < 0.01), psychological (P < 0.01), and social (P < 0.01), with P ≤ 0.05 being considered statistically significant except environmental domain. Between groups, analysis shows that in the preintervention, there was no difference between the yoga and control group as P > 0.05. After the yoga intervention, there was an enhancement in QoL scores with three domains except the environmental domain (P = 0.28). The study evidence supports the use of yoga as a complementary therapy for the NTEP in patients with PTB may improve their QoL.
