Effect Of Whole Body Vibration On Reduction Of Bone Loss And Fall Prevention In Postmenopausal Women

Background:To examine the effect of whole body vibration (WBV) on bone mineral density (BMD) and fall prevention in postmenopausal women, we performed a meta-analysis and systematic review of prospective randomized controlled trials (RCTs) comparing change in BMD of femoral neck and lumbar spine and related factors of falls between WBV group and control group.Methods:A search of EMBASE, Pubmed, Cochrane Central Register of Controlled Trials, ISI Web of Science and China National Knowledge Infrastructure (CNKI) were done, search strategy was used as follows:(vibration) AND (osteoporo* OR muscle* OR bone mineral density OR BMD). All prospective randomized controlled trials comparing related factors of falls and BMD change in femoral neck and lumbar spine between WBV group and control group were retrieved.Results:Eight studies with 1014 patients were included,477 in the WBV group and 537in the control group. We found that there was no significant difference in all magnitude group of the femoral neck (N= 936, WMD:0.00 (-0.00,0.01); p=0.18). A statistical significance showed in the all magnitude group (N=1014, WMD:0.01 (0.00,0.01); p=0.01) and low-magnitude group (N= 838, WMD:0.01 (0.00,0.01); p=0.007) of lumbar spine. All the studies provided data of related factors of falls such as strength of lower-limb, balance and fall rate reported effectiveness of WBV therapy. In addition, no complication was reported.Conclusion:Low-magnitude whole body vibration therapy can provide a significant improvement in reducing bone loss in lumbar spine in postmenopausal women. Moreover, whole body vibration can be used as an intervention for fall prevention.
