Whole-Body Vibration Training Protocols for People with Cerebral Palsy: a Systematic Review of Randomised Controlled Trials

Abstract

Objectives: Whole-body vibration training (WBVT) has been emerging as a promising therapeutic modality for cerebral palsy (CP); however, reported efficacy is inconsistent and methodological approaches differ substantially. This study aimed to review the methodological protocols adopted by randomised controlled trials reporting on the efficacy of WBVT for people with CP. Methods: Electronic databases were searched for randomised controlled trials reporting on the efficacy of WBVT for people with CP. Data were extracted from included studies related to study and participant characteristics and WBVT protocols including training programmes, patient positioning, and machine and vibration specifications. Results: Eighteen randomised controlled trials were identified. Training programmes varied considerably, including duration, number of sessions per week, session length, and whether static, dynamic, or combination exercises were performed. Positioning of participants on the vibration platform also varied, including foot, knee, hip, and hand positioning. The machine specifications were poorly reported, with variations in frequency, amplitude, and peak acceleration settings. Conclusions: This review highlights the inconsistency in the use and reporting of training protocols, machine specifications, and patient positioning when investigating the efficacy of WBVT for people with CP. Current clinical trials continue to poorly acknowledge WBVT research recommendations, which may contribute to ongoing misunderstanding of basic WBVT principals and safety considerations, as well as contribute to the inconclusive results with regard to treatment efficacy.
