A group of American authors has created an evidence map of the effect of tai chi on various health outcomes, based on a systematic review of 107 systematic reviews. The map identified a number of areas with evidence of a potentially positive treatment effect on patient outcomes, indicated by statistically significant pooled treatment effects in systematic reviews, and based on a substantial number of research studies. These included hypertension, fall prevention, cognitive performance, osteoarthritis, depression, chronic obstructive pulmonary disease, pain, balance and muscle strength.
