RecruitingBehavioural interventionThe Effect of a Technology-Mediated Integrated Walking and Tai Chi Intervention on Physical Function in Veterans With COPD and Chronic Musculoskeletal PainPersons with COPD benefit from being physically active, but they are often limited by chronic musculoskeletal pain. This project will determine whether a non-pharmacologic, integrated, technology-mediated walking and Tai Chi mindfulness intervention can improve physical function in Veterans with COPD and chronic musculoskeletal pain. The proposed research addresses VA Rehabilitation R\&D Service's high priority area of improving health-related quality of life by reducing disease burden and maximizing function in Veterans with chronic disease.
