Background: Despite clinical use of whole body vibration treatment has emerged as a useful intervention for improving overall health including BMD in various population, previous studies have reported heterogeneous results on the effect of whole body vibration treatment on BMD.
Purpose: We systematically reviewed the effects of whole body vibration treatment (WBV) on bone mineral density in functionally impaired children with neuromuscular disorder.
Materials and Method: We systematically searched PubMED, Embase, Cochrane database, and Google Scholar up to June 2020. The inclusion criteria were: (1) A quantitative study design, (2) investigation of the effects of whole body vibration on bone mineral density, (3) enrolment of children with functionally impaired children with neuromuscular disorder, (4) participants without metabolic disorders or primary disorder including muscle and bone. Standardized mean difference (SMD), 95% confidence intervals (CIs) and p-values were calculated for analysis.
Result: Of 85 initially identified studies, five met the inclusion criteria: three randomized clinical trial, one clinical trial and one repeated measure study. BMD of the femur and lumbar spine significantly improved after applying whole body vibration treatment compared to pre-treatment values (Lumbar spine: SMD, 1.68; 95% CI, 0.47-2.89; p<0.01, Femur neck: SMD, 1.11; 95% CI, 0.74-1.48; p<0.01 ).
Conclusion: Weight bearing exercise has a significant effect on improving BMD of the femur and lumbar spine in functionally impaired children.
