VIRTUAL REALITY-BASED REHABILITATION FOR STROKE RECOVERY: A SYSTEMATIC REVIEW OF RANDOMIZED CONTROLLED TRIALS

Abstract

Background: Stroke may also affect motor abilities, balance and cognitive abilities, and is a major cause of disability in the world. Virtual reality (VR) is a new approach to rehabilitation providing attractive therapeutic environments, which are interactive, task-focused, and can significantly enhance the recovery. Objective:The intent of this project is to review extensively literature on the topic of virtual reality (VR) rehabilitation and its impact on motor, balance, cognitive, and psychosocial outcomes in stroke patients. Methods:We followed the PRISMA criteria when we performed our systematic review of RCTs. Studies were included from the year 2022–2026.  Studies assessing VR based interventions in stroke rehabilitation were selected. Data were extracted and synthesized narratively Due to methodological, intervention and outcome measurement inconsistencies among all the studies. The PEDro scale was used to evaluate the quality of the methods, and the Cochrane Risk of Bias 2 tool was used to evaluate the risk of bias. Results:The upper limb motor function was significantly improved with VR-based therapy as shown by all of the research that were considered.  balance, gait, cognitive performance, and psychological outcomes. Immersive and combined VR interventions showed greater improvements in some studies; however, several trials reported comparable outcomes between VR and conventional therapy. VR interventions also enhanced patient engagement, motivation, and adherence to rehabilitation. The methodological quality on the whole, was moderate to high and the risk of bias was low-moderate. Conclusion:Virtual reality (VR) is a promising tool for stroke patients' rehabilitation. particularly as an adjunct to conventional therapy. While it consistently improves multiple functional outcomes, its superiority over traditional rehabilitation remains inconclusive. Further testing with standard methods and prospective follow up would be needed for it to be fully utilized in the clinic.
