Tai Chi and yoga as complementary therapies in rheumatologic conditions

Tai Chi and yoga are complementary therapies which have, during the last few decades, emerged as popular treatments for rheumatologic and musculoskeletal diseases. This review covers the evidence of Tai Chi and yoga in the management of rheumatologic diseases, especially osteoarthritis of the knee, hip and hand, and rheumatoid arthritis.There is evidence that Tai Chi and yoga are safe, and some evidence that they have benefit, leading to reduction of pain and improvement of physical function and quality of life in patients. Recommendations for Tai Chi in knee osteoarthritis have recently been issued by the American College of Rheumatology. To allow broader recommendations for the use of Tai Chi and yoga in rheumatic diseases, there is a need to collect more evidence researched with larger randomised controlled trials.
