The effect of whole body vibration in common neurological conditions - a systematic review

Background: Whole body vibration (WBV) is a new therapeutic tool used to improve muscle strength, power and postural control in various healthy and pathological populations. Aim: The aim of this systematic review was to summarise and evaluate the available literature on the effectiveness of WBV in neurological conditions. Method: A systematic review of the literature was performed to identify randomised controlled trials (RCTs) examining the effect of WBV on common neurological conditions. The methodological quality of the studies was systematically assessed using the PEDro rating scale. Reported outcomes were assessed for differences between the experimental and control groups and effect sizes were calculated. Results: Five RCTs and two pseudo RCTs were included. Methodological scores ranged from 1 to 9 ( maximum 11) with a mean score of 5.71 (SD 2.69). There is weak to moderate evidence for positive effects on postural control, mobility, motor function and strength following the single application of WBV in neurological populations. A paucity of available literature into repeated WBV training prevents the drawing of firm conclusions regarding long-term treatment effectiveness. Conclusion: Despite being a new technique, there is early evidence that WBV applied to neurological populations has positive effects on postural control, mobility, motor function and strength. Further studies into the effectiveness of WBV in neurological populations are warranted.
