Tai Chi is effective in treating knee osteoarthritis: a randomized controlled trial

Current guidelines consider non-pharmacological treatment modalities as the cornerstones in modern management of OA with information, exercise, and weight loss as core treatments (NICE 2008). Although this trial involved instruction by a Tai Chi master and selected participants, the study results might encourage physiotherapists to consider Tai Chi as an alternative, or additional, form of exercise for persons with knee OA.
