Objective To evaluate the quality of literature and the quality of evidence of outcome measures related to systematic reviews of Tai Chi in the prevention and treatment of osteoporosis. Methods PubMed, EMbase, the Cochrane Library, PROSPERO, WBC, CBM, CNKI, WanFang and VIP database were searched to collect systematic reviews of Tai Chi in the prevention and treatment of osteoporosis. The methodological quality and reporting quality of the included studies was evaluated using the AMSTAR-2 scale and PRISMA score respectively, and the outcome measures were graded for the quality of evidence according to the GRADE tool. Results A total of 13 systematic reviews were included, one of the studies had relatively high methodological quality, while the others had low or very low quality. The PRISMA score varied from 12 to 24 points. The main problems existed in protocol registration, risk of bias assessment, heterogeneity, publication bias, data combination and analysis. The GRADE evaluation results showed that of the 44 outcome measures included, 8 outcome measures were of moderate quality, 22 were of low quality, and 14 were of very low quality, and the outcome measures of moderate quality suggested that Tai Chi had a better improvement effect on the spine, lumbar spine, and femoral neck than the control group. Conclusion The systematic reviews of Tai Chi for osteoporosis are generally of low quality and the evidence strength of the conclusions is low, large sample, high-quality studies are still needed to further evaluate its effectiveness in the future. |
