Abstract:

BACKGROUND: There is no consensus on the effectiveness and safety of Tai Chi of traditional body refreshment for patients concerning bone mineral density loss, which needs further investigation.
OBJECTIVE: To assess the effectiveness and safety of Tai Chi of traditional body refreshment for improving bone mineral density loss.
METHODS: Databases including CNKI, WanFang, VIP, CBM, PubMed, MEDLINE, EMbase and Cochrane Library were searched by computer for randomized controlled trials involving Tai Chi of traditional body refreshment (including Tai Ji Quan, Tai Chi push hand, Tai Chi softball, et al.) on the effect of bone health/bone mineral density published before January 2019. The related periodicals were also manually retrieved. Literature screening, data extraction and methodological quality were conducted based on the Cochrane methods. Meta-analysis was performed on RevMan 5.3 software.
RESULTS AND CONCLUSION: Fourteen articles including 16 randomized controlled trials were included. Meta-analyses results found that: Tai Chi of traditional body refreshment was superior to the control group in improving bone mineral density of L2-4 (SMD=0.40, 95%CI[0.16, 0.65], P=0.001), and femoral neck (SMD=0.75, 95%CI [0.27, 1.24], P=0.002). Furthermore, no significant differences were observed between groups in bone mineral density of Ward’s triangle (SMD=0.50, 95%CI[-0.10, 1.10], P=0.10), femoral shaft (SMD=0.16, 95%CI [-0.11, 0.44], P=0.25), proximal femoral trochanter (SMD=0.54, 95%CI [-0.01, 1.09], P=0.05), and 1/3 distal radius (SMD=0.20, 95%CI [-0.26, 0.66], P=0.040). No seriously adverse events were reported. Current evidence suggest that Tai Chi of traditional body refreshment shows additive benefits for the improvement of bone mineral density loss of lumbar spine and femoral neck in specific populations (such as elderly, osteoporosis groups, perimenopausal and postmenopausal women). In view of the study of small number and itself limitations, further clinical trials with high quality and rigorous design are needed for further verification.
