Tai chi provides greater fall-prevention benefits than conventional physical therapy exercises for frail seniors, according to a Canadian study. A total of 152 frail older adults were randomised to receive a 15-week intervention, consisting of either supervised tai chi exercises, or conventional physical therapy. Both interventions demonstrated a protective effect on falls, but the effect of tai chi was significantly greater compared with physical therapy.
