What was done
A systematic review and meta-analysis of randomized controlled trials was conducted across PubMed, EMBASE, Web of Science, CENTRAL, and PEDro databases to assess the efficacy of whole-body vibration (WBV) on bone mineral density (BMD), pain levels, and body composition in postmenopausal women with osteoporosis.
What was found
Across 13 randomized controlled trials (783 patients), WBV significantly increased lumbar spine BMD (WMD = 0.018; 95% CI: 0.004 to 0.032; P = 0.011) and femoral neck BMD (WMD = 0.005; 95% CI: 0.001 to 0.011; P = 0.0493), and significantly reduced pain degree (WMD = -0.786; 95% CI: -1.300 to -0.272; P = 0.0027). WBV had no significant effect on muscle mass (WMD = 0.547; 95% CI: -1.104 to 2.199; P = 0.5158) or fat mass (WMD = 0.530; 95% CI: -2.389 to 3.448; P = 0.7222).
Why it matters
This review synthesizes trial data showing that whole-body vibration provides modest site-specific increases in bone mineral density and pain relief for postmenopausal osteoporosis.
Limits
The abstract does not provide specific vibration parameters, intervention durations, comparator details, or adverse effect reporting. Clinical significance of the very small absolute increases in BMD and the impact on actual fracture risk were not reported.
