Abstract
This study was conducted to obtain evidence that virtual reality has an effect on balance in children with cerebral palsy and to provide physical therapists with guidelines therefor they can improve balance in children with cerebral palsy using virtual reality.Method: Systematicreview methodology was used to systematically and comprehensively search the web literature according to criteria included in Cochrane Handbook for Systematic Reviews of Interventions, Electronic searches were done using PubMed, Cochrane Central Register of Controlled Trials, Pedro and Google scholar. Consensus was achieved following two reviewers’ independent inclusion screening, data extraction and appraisal.Subjects:This systematic review concerned children with cerebral palsy (hemiplegia or diplegia), aged between 7 and 18 years, had according to Gross Motor Functional Classification System (GMFCS)level of I or II, could walk unaided for a period of ten minutes and had not previously used virtual reality.Results:This systematic review includes four studies that fulfilled inclusive criteria, studying the effect of virtual reality on balance (as primary outcome) in cerebral palsied children and on secondary outcomes ; Gross motor functions, functional mobility, upper limb function and control and synchronization of movement. The whole number of participants included in this review was 52participants, with age ranged from 7 to 18years. All four studies included in the descriptive analysis due to heterogeneity of the primary and secondary outcomes. Conclusion:The current level of evidence to support the effectiveness of virtual reality on promoting balance in children with cerebral palsy remains weak. The main limitations are the heterogeneity between included studies in the review and the small number of the studies involved
