Context: The concerns of caregivers of patients with neurological disorders have been a felt need for a long time, with many of them experiencing significant psychiatric morbidity. Aims: This study aimed to find the effect of yoga in reducing anxiety and depression, as well as improving quality-of-life in caregivers of patients with neurological disorders. Settings and Design: The study was conducted using a randomized controlled design, with yoga intervention and waitlisted controls. Methodology: Sixty consenting caregivers of inpatients in neurology wards were randomized into two groups: Yoga and control. Demographic variables except years of education and length of caretaking were comparable in the two groups, as also baseline scores of anxiety, depression and quality-of-life. A specific yoga module comprising yogāsanas, prāṇāyāma, and chanting was taught to the participants in the yoga group by the researcher. At follow-up 43 patients (yoga n=20 and control group n=23) were available. Two-way repeated measures analysis of variance was used to test the change from pre-test to post-test scores within and between groups. Analysis of covariance was performed to compare the post-test scores between the groups adjusting for education and length of caretaking. Results: Following one month intervention of yoga therapy, there was a significant ( P<0.001) decrease in anxiety and depression scores, as well as improved quality-of-life among the participants in the yoga group as compared with the control group. Conclusion: This study highlights the usefulness of a yoga intervention for caregivers of inpatients with neurological problems. The small sample size and lack of blinding were some of the limitations of this study.
