 Management of dyspnea shortness of breath is a major concern for patients with COPD. The efficacy of complementary exercises to manage dyspnea is unknown. Complementary exercises may be more congruent with patients lifestyles and values than traditional exercise programs and can be adapted to changes in illness severity and disability. Yoga practice is a complementary therapy that people use to manage their dyspnea. The aims of this study are to: 1 develop a safe and feasible yoga program for patients with COPD; 2 test the efficacy of this program; and 3 determine whether physical performance, psychological well being, and health-related quality of life are positively affected by yoga practice.
