Purpose Overseas studies and reviews showed that about 30% of elderly suffer from falls every year and approximately one fall in ten resulted in fractures. Fall is a major cause of hospitalization in Hong Kong, ranking the fifth in terms of total bed days of all public acute hospitals. Tai Chi (TC) is a Chinese martial art form for centuries and seems to be an effective intervention to prevent falls through improving functional balance and physical response. Methods A prospective observational study of 3,222 communitydwelling elderly aged 60 or above was conducted to assess the effect of TC in reducing injurious falls incidence. Participants were community-dwelling elderly aged 60 or above with “Timed Up-and-Go” test (TUGT) less than or equal to 20 seconds. An hour simplified TC session led by recognized TC coaches was performed twice a week in a period of four weeks. Participants were encouraged to practice TC after training. Injurious fall incidents were retrieved and compared from a medical records database 12 months before and after TC training between 2 strata: continue (n=1,269) vs cease (n=1,360) TC in 12 months post training. Results The injurious fall rate dropped from 2.21% (pre) to 1.34% (post) in the continuing TC group while the fall rate increased from 2.06% (pre) to 3.46% (post) in the noncontinuing TC group. The percentage of hospitalization due to fall-related injuries was 0.39% and 1.03% in the continuing and non-continuing TC groups, respectively. Conclusion Study results demonstrate that TC has a potential preventive effect on injurious falls and hospital utilization.
