Abstract
Virtual reality (VR) interventions have been increasingly used in the rehabilitation of a wide range of neurological and neuropsychological dysfunctions. Findings of previous reviews showed positive and promising effects of VR-based interventions. However, they summarized findings on VR-based intervention carried out through different VR systems and tasks. We carried out a narrative review with the aim of qualitatively synthesising the results of previous studies that used specific VR systems, i.e. the Khymeia -Virtual Reality Rehabilitation System, for treatment purposes. We searched the literature in various databases (i.e. EMBASE, Web of Science, SCOPUS, PubMed and PubMed Central) for studies published until November 23, 2023. 30 studies were selected. The VRRS was used for neuromotor rehabilitation only in 13 studies, for cognitive rehabilitation in 11 studies, and for both neuromotor and cognitive rehabilitation in six studies. The study design was heterogeneous including 15 randomised controlled trials. After discussing each study according to the type of rehabilitation we concluded that the use and efficacy of VRRS rehabilitative intervention for increasing the neurological and neuropsychological functioning of patients are promising but more evidence is needed to make a comparison with conventional treatment. Future studies should also include long-term follow-up as well as cost-effectiveness analysis.
