OBJECTIVE: To investigate the effect of whole-body vibration exercise (WBV) on
fracture risk in adults ?50 years of age. DESIGN: A systematic review and
meta-analysis calculating relative risk ratios, fall rate ratio and absolute
weighted mean difference using random effects models. Heterogeneity was estimated
using I(2) statistics, and the Cochrane Collaboration's risk of bias tool and the
GRADE approach were used to evaluate quality of evidence and summarise
conclusions. DATA SOURCES: The databases PubMed, Embase and the Cochrane Central
Register from inception to April 2016 and reference lists of retrieved
publications. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled
trials examining the effect of WBV on fracture risk in adults ?50 years of age.
The primary outcomes were fractures, fall rates and the proportion of
participants who fell. Secondary outcomes were bone mineral density (BMD), bone
microarchitecture, bone turnover markers and calcaneal broadband attenuation
(BUA). RESULTS: 15 papers (14 trials) met the inclusion criteria. Only one study
had fracture data reporting a non-significant fracture reduction (risk ratio
(RR)=0.47, 95%?CI 0.14 to 1.57, P=0.22) (moderate quality of evidence). Four
studies (n=746) showed that WBV reduced the rate of falls with a rate ratio of
0.67 (95% CI 0.50 to 0.89, P=0.0006; I(2)=19%) (moderate quality of evidence).
Furthermore, data from three studies (n=805) found a trend towards falls
reduction (RR=0.76, 95%?CI 0.48 to 1.20, P=0.24; I(2)=24%) (low quality of
evidence). Finally, moderate to low quality of evidence showed no overall effect
on BMD and only sparse data were available regarding microarchitecture
parameters, bone turnover markers and BUA. CONCLUSIONS: WBV reduces fall rate but
seems to have no overall effect on BMD or microarchitecture. The impact of WBV on
fractures requires further larger adequately powered studies. This meta-analysis
suggests that WBV may prevent fractures by reducing falls. PROSPERO REGISTRATION
