  • Objectives To analyze the effectiveness of tai chi for falls prevention.

    Design Systematic review and meta-analysis.

    Setting Pubmed, Scopus, CINHAL, and Physiotherapy Evidence Database (PEDro) were searched to May 26, 2016.

    Participants Older adult population and at-risk adults.

    Intervention Randomized controlled trials analyzing the effect of tai chi versus other treatments on risk of falls.

    Measurements The incidence rate ratio (IRR) for falls incidence and hazard ratio (HR) for time to first fall.

    Results The search strategy identified 891 potentially eligible studies, of which 10 met the inclusion criteria. There was high-quality evidence of a medium protective effect for fall incidence over the short term (IRR = 0.57; 95% CI = 0.46, 0.70) and a small protective effect over the long term (IRR = 0.87; 95% CI = 0.77, 0.98). Regarding injurious falls, we found very low-quality evidence of a medium protective effect over the short term (IRR = 0.50; 95% CI = 0.33, 0.74) and a small effect over the long term (IRR = 0.72; 95% CI = 0.54, 0.95). There was no effect on time to first fall, with moderate quality of evidence (HR = 0.98; 95% CI = 0.69, 1.37).

    Conclusion In at-risk adults and older adults, tai chi practice may reduce the rate of falls and injury-related falls over the short term (<12 months) by approximately 43% and 50%, respectively. Tai chi practice may not influence time to first fall in these populations. Due to the low quality of evidence, more studies investigating the effects of tai chi on injurious falls and time to first fall are required.
