Virtual Reality for Balance After Stroke: A Narrative Review.

Background: The present study was conducted to provide an upto-date understanding of clinical applications in balance capability, as well as delivering a review of pieces of literature on Virtual Reality (VR) on balance control in stroke survivors. Methods: Databases including PubMed, Cochrane Library, and Pedro were searched for published papers from 2010 to 2020 with the terms "Game-based rehabilitation", "balance training", "virtual reality", "stroke", "neurorehabilitation", and "virtual environment". We evaluated the effect of VR on balance improvement after a stroke. Results: 33 articles describing results following the use of VR on balance in patients with stroke that met our inclusion criteria were found. Among these studies, two studies described the results in acute, eight in subacute, twenty-two in chronic stroke patients, and one study included both chronic and subacute stroke patients. The results indicated that balance can be improved with VR. Conclusion: The results of this study strengthen the idea that VR training has the potential to become an effective adjacent to routine rehabilitation treatments for improving balance status post-stroke. However, conducting a randomized control trial that incorporates all three stroke phases with an appropriate study setting is necessary to achieve an integrated clinical protocol.
