Effects of virtual reality rehabilitation after spinal cord injury: a systematic review and meta-analysis.

Background: Spinal cord injury (SCI) is a common neurological condition marked by damage to the spinal cord. In the field of neurological rehabilitation, virtual reality (VR) is increasingly employed for evaluating and addressing the physical limitations caused by SCI. This study aimed to describe and calculate the effect sizes of virtual reality intervention (VR) on the functional performance of SCI.

Methods: We searched PubMed, Embase, Web of Science, and Cochrane Library to identify articles published before October 30, 2023, that addressed the intervention of SCI using virtual reality technology. We excluded from the meta-analysis articles that did not provide enough data to evaluate the association between virtual reality intervention and spinal cord injury. The RevMan 5.4 statistical software was used for data analysis.

Results: We included 16 articles in the systematic review and pooled 9 for the meta-analysis, which were 5 randomized controlled trials (RCTs) and 4 non-RCTs, including 248 subjects. The outcome measure of the walking index for spinal cord injury, limits of stability testing and berg balance scale scores improved in non-RCTs.

Conclusion: VR has shown promise in enhancing walking ability and balance function in individuals with SCI. However, the existing evidence for VR interventions in SCI patients remains limited, highlighting the necessity for future studies in this area.
