Objective:This study was intended to assess the effect of Tai Chi on the prevention of fall among the elderly.Methods:Relevant randomized controlled trials published since inception up to 6 January 2019 were selected in the electronic databases(PubMed,Cochrane Library,Web of Science,EMBASE,CBM,CNKI and Wan fang).Two researchers independently screened the literature,extracted data and evaluated the literature quality.Publication bias was assessed by Forest plot,Begg's test and Egger's test.STATA 14.0 software was used to do meta-analysis on the relationship between TAI Chi and fall.This study was registered at international prospective register of systematic Reviews(number:CRD42019122958).Results:A total of 6 RCTs were included.The results showed that,the incidence of fall among the elderly in Tai Chi group is less than that of blank group[RR=0.44(0.21-0.90)],but no statistical difference in the comparison of Tai Chi plus education and education[RR=0.96(0.76-1.22)],which was also supported by subgroup analysis.Meanwhile,similar result also appeared in the comparison of Tai Chi group and education group[RR=0.73(0.51-1.06)].Conclusion:Tai Chi could reduce the incidence of falls among the elderly,but the effect of Tai Chi plus education/Tai Chi on the incidence of falls is consistent with education alone.Therefore,we should pay attention to fall-related education among the elderly.
