Effects of whole-body vibration on muscle strength, bone mineral content and density, and balance and body composition of children and adolescents with Down syndrome: a systematic review.
The aim of this study is to verify the effects of whole-body vibration (WBV) training on the muscle strength of children and adolescents with Down syndrome. We searched MEDLINE, Cochrane, SciELO, Lilacs and PUBMED databases and included manual searches to identify randomised controlled trials to investigate the effects of WBV on the structure and body function of children and adolescents with Down syndrome. Two reviewers independently selected the studies and performed statistical analysis. In total, five studies with 171 patients that compared WBV with exercise and/or control were included. Two studies demonstrated a significant difference between the muscle strength of children and adolescents with Down syndrome who received WBV training and that of those who did not receive the intervention. The studies included in this systematic review showed that WBV training has positive effects on bone mineral density (BMD), body composition and balance. Results of this study showed that WBV training improves muscle strength, BMD, body composition and balance of children and adolescents with Down syndrome, and a more in-depth analysis of its effects on other variables in this population is required, as well as of parameters to be used.
