We are indebted to Li et al.1 for their demonstration that an intervention exercise regime based on tai chi is not only effective for preventing falls among elderly persons but also can be well tolerated and thoroughly enjoyed. The participants in their study also likely benefited in other ways: physiologically, psychologically, and socially. It appears that even a brief exposure to a simplified version of tai chi can be effective for highly motivated elderly participants with a fear of falling.
