Background: Childhood neurological diseases result in neuromotor impairment, which affects selective motor control, compromising the acquisition of motor skills and functional independence. The positive results achieved with virtual reality are believed to be related to training in an interactive environment that provides a broad range of activities and scenarios with multiple sensory channels, enabling the creation of exercises at an intensity based on individual need. Therefore, a review was conducted to answer the following question: What are the possible effects of virtual reality for the pediatric population, specifically children with cerebral palsy and Down syndrome?
Objective: The objective of the present study was to conduct a systematic review of the literature to determine the possible effects of virtual reality therapy in children with cerebral palsy and Down's syndrome.
Methods: The PubMed, Bireme, Scielo and PEDro electronic databases were searched in the period from January to March 2016 using the following keywords: Down syndrome and virtual reality, virtual reality and cerebral palsy, virtual reality and neuropediatrics, and Down's syndrome and virtual reality. Only randomized controlled trials published in English in the previous 10 years (2007-2016) that addressed the specific purpose of this review and achieved a score of at least 4 points on the PEDro methodological quality scale were eligible for inclusion.
Results: The initial research led to the retrieval of 214 articles, which were analyzed considering the inclusion criteria. Eighteen articles were submitted to an appraisal of methodological quality using the PEDro scale, only five of which received a score of four or more points and were described in the present review. Three of the studies selected analyzed children with cerebral palsy and two analyzed children with Down syndrome. Despite the different physiopathological characteristics of the two conditions, the authors employed similar therapeutic methods and evaluations. The results of the studies demonstrated that virtual reality training either alone or combined with motor training leads to improvements in sensory-motor functions and can be used as a complement to other successful rehabilitation interventions in the two populations.
Conclusion: Based on the results of the studies included in the present systematic review, despite differences in the characteristics of each population, the objectives and methods proposed by the authors were similar and virtual reality demonstrated promising effects for individuals with cerebral palsy and Down syndrome.
