Therapeutic effects of whole-body vibration on postmenopausal women with osteoporosis: a systematic review and meta-analysis.

The objective of this study was to assess the efficacy of whole-body vibration (WBV) on bone mineral density (BMD), pain levels, and body composition in postmenopausal women with osteoporosis (PMOP). Relevant studies were retrieved from the PubMed, EMBASE, Web of science, CENTRAL, and PEDro databases. Thirteen randomized controlled trials with 783 patients were enrolled. The meta-analysis results showed that WBV can significantly increase lumbar spine BMD (WMD=0.018; 95%CI: 0.004 to 0.032; P=0.011), femoral neck BMD (WMD=0.005, 95%CI: 0.001 to 0.011, P=0.0493), and reduce pain degree (WMD=-0.786; 95%CI: -1.300 to -0.272; P=0.0027) in PMOP, but has no significant effect on patients' muscle mass (WMD=0.547; 95%CI: -1.104 to 2.199; P=0.5158) as well as fat mass (WMD=0.530; 95%CI: -2.389 to 3.448; P=0.7222). To conclude, WBV showed the potential to provide positive benefits in improving BMD and relieving pain of PMOP.
