Abstract Background Virtual Reality (VR) is an emerging technology in post stroke recovery. However, its precise role in stroke rehabilitation is not well defined. The aim of this paper is to conduct an overview of systematic reviews on the role of VR in stroke rehabilitation. Methods A meta-review with results from a search of 7 databases from inception till 5th December 2022 with subsequent quality appraisal was conducted. The primary outcome was to produce a narrative review on the efficacy of VR versus usual or other care in stroke recovery. Data was synthesized in a descriptive fashion and high-quality systematic reviews were emphasized. The AMSTAR-2 tool was used for quality assessment of the included studies. Results Evidence from high-quality systematic reviews suggests that there is benefit from VR in upper limb, lower limb, gait, and balance recovery particularly when additive to conventional therapy. There is also limited evidence to suggest that VR has a positive effect in those with impaired cognition. Conclusion VR is safe and effective as an adjunct to conventional therapy for adults after stroke and should be used routinely for upper and lower limb motor recovery. Further high-quality studies that evaluate its efficacy and explore ways to increase its positive impact in areas such as cognition are required. There is also a scope for the development of stroke-specific virtual environments. (PROSPERO registration # CRD42022372926).
