Tai chi was shown to have a favorable effect on physical performance in four chronic conditions, including COPD.
Yi-Wen Chen, from the University of British Columbia in Canada, and colleagues conducted a systematic review to summarize evidence relating to tai chi effectiveness in individuals with cancer, osteoarthritis, heart failure, and chronic obstructive pulmonary disease (COPD). Data were included from 33 studies. For each chronic condition, meta-analyses were performed on disease-specific symptoms, physiological outcomes, and physical performance.
The researchers found that in most or all of the four conditions, tai chi improved or showed a tendency to improve physical performance outcomes, including six-minute walking distance and knee extensor strength. In osteoarthritis, tai chi was associated with improvements in disease-specific symptoms of pain and stiffness.
