Effectiveness of Virtual Reality Rehabilitation in Improving Balance and Gait in Stroke Patients: A Randomized Controlled Trial

Thesis Abstract

Abstract
Stroke is a leading cause of long-term disability worldwide, often resulting in impairments such as balance and gait disturbances. Traditional rehabilitation methods have limitations in addressing these issues comprehensively. Virtual reality (VR) rehabilitation has emerged as a promising intervention for improving balance and gait in stroke patients. This study aimed to investigate the effectiveness of VR rehabilitation in enhancing balance and gait outcomes in stroke patients through a randomized controlled trial (RCT). The study design was a RCT involving stroke patients with balance and gait impairments. Participants were randomly assigned to either the VR rehabilitation group or the control group receiving traditional rehabilitation. The VR rehabilitation group underwent a structured program utilizing VR technology to target specific balance and gait components, while the control group received standard physical therapy interventions. The primary outcome measures included balance assessment using the Berg Balance Scale and gait analysis through gait speed and gait symmetry measurements. Secondary outcomes encompassed functional mobility, quality of life, and patient satisfaction with the intervention. Data were collected at baseline, post-intervention, and follow-up assessments to evaluate the short-term and long-term effects of VR rehabilitation. Results indicated that the VR rehabilitation group demonstrated significant improvements in balance and gait parameters compared to the control group. Specifically, individuals in the VR group exhibited enhanced balance control, increased gait speed, and improved gait symmetry following the intervention. These improvements were sustained at the follow-up assessment, suggesting the durability of the effects of VR rehabilitation on balance and gait outcomes in stroke patients. Furthermore, participants in the VR group reported high satisfaction levels with the intervention, indicating positive acceptance and engagement with the VR rehabilitation program. The findings underscore the potential of VR technology as an effective and engaging tool for enhancing balance and gait rehabilitation in stroke patients. In conclusion, this RCT provides robust evidence supporting the effectiveness of VR rehabilitation in improving balance and gait in stroke patients. The results highlight the value of incorporating VR technology into rehabilitation protocols to optimize functional outcomes and enhance the quality of life for individuals post-stroke. Future research should explore the long-term benefits and cost-effectiveness of VR rehabilitation to further establish its role in stroke rehabilitation practices.
