Review of controlled trials show tai chi to be effective at reducing risk of falls among seniors.

A systematic review of randomizes trials of interventions to reduce falls in community-dwelling seniors published in the April 2009 Cochrane Database Syst Rev. found that tai chi is effective at reducing the rate of falls. In addition to tai chi, multiple-component group exercise, individually prescribed multiple-component home-based exercise, and assessment and multifactorial intervention were also found to be effective. Of these tai chi had the greatest estimated reduction in falls. A number of other interventions were also found to be effective, however these only applied to selected situations or populations such as anti-slip shoes in icy conditions and first eye cataract surgery.
