Objective: To systematically evaluate the effects of whole body vibration training on chronic ankle instability. Methods: The randomized controlled trials (RCTs) about whole body vibration training on chronic ankle instability were searched from CNKI, WanFang, Vip, PubMed, Embase, The Cochrane Library, Web of Science, Science Direct until July 2019. Two judges independently screened literature, collected data and conducted quality assessment. Data were analyzed with RevMan5.3 software. Results: A total of 222 patients with 7 RCTs were included. The results of meta-analysis revealed that whole body vibration training was more effective in improving the Y balance test score of patients with chronic ankle instability [WMD=5.69, 95%CI (4.33, 7.06), P<0.00001], unilateral stability index of the affected side [WMD=-0.13, 95%CI (-0.17,-0.10), P<0.00001], response time of the long fibula muscle [WMD=-7.14, 95%CI (-13.41, -0.86), P=0.03] than the control group. However, based on the current evidence, there was no statistically significant difference between whole body vibration training and the control group in improving the functional scale [SMD=-0.16, 95%CI (-0.63, 0.31), P=0.50]. Conclusion: The current evidence shows that the whole body vibration training can effectively improve the balance ability of patients with chronic ankle joint instability and enhance the neuromuscular response ability of the long fibula muscle. |
