A growing body of knowledge supports the health benefits of regular tai chi practice. Evidence from a comprehensive review of more than 200 studies confirms the therapeutic value of tai chi practice for improving quality of life, pain management and physical function (including activity tolerance and cardiovascular function); reducing the risk of falls; enhancing immune response; and increasing flexibility, strength, balance and kinesthetic awareness. The review was published in the American Journal of Physical Medicine and Rehabilitation (2004; 83, 735–45).
