Randomized Controlled Trial
Impact of tai-chi on falls among preclinically disabled older people. A randomized controlled trial.
To investigate the effectiveness of tai-chi in preventing falls among community-dwelling older people. ⋯ This study does not support modified Sun style tai-chi as a falls prevention measure among relatively well community-dwelling older people with modified mobility and at increased risk of disability. Insufficient intervention intensity, or low exercise class attendance may have contributed to the lack of effect, as may have attrition bias among the intervention group.
