Randomized Controlled Trial of Yoga for Chronic Poststroke Hemiparesis: Motor Function, Mental Health, and Quality of Life Outcomes

Abstract

Purpose: To assess the efficacy of yoga for motor function, mental health, and quality of life outcomes in persons with chronic poststroke hemiparesis. Method: Twenty-two individuals participated in a randomized controlled trial involving assessment of task-orientated function, balance, mobility, depression, anxiety, and quality of life domains before and after either a 10-week yoga intervention (n = 11) or no treatment (n = 11). Results: The yoga intervention did not result in any significant improvements in objective motor function measures, however there was a significant improvement in quality of life associated with perceived motor function (P = .0001) and improvements in perceived recovery approached significance (P = .072). Memory-related quality of life scores significantly improved after yoga intervention (P = .022), and those participating in the intervention exhibited clinically relevant decreases in state and trait anxiety. Conclusions: Preliminary results offer promise for yoga as an intervention to address mental health and quality of life in persons with stroke-related activity limitations. There is a need to more rigorously evaluate these yoga benefits with a larger randomized controlled trial, which, based on this preliminary trial, is feasible.
