Virtual reality-enhanced partial body weight-supported treadmill training poststroke: feasibility and effectiveness...

Area of Science:

• Neurorehabilitation
• Biomedical Engineering
• Physical Therapy

Background:

• Stroke survivors often experience persistent gait and balance deficits despite completing traditional rehabilitation.
• Partial body weight-supported treadmill training (BWSTT) is a common intervention to improve walking post-stroke.
• Virtual reality (VR) offers immersive environments that can enhance motor learning and engagement during rehabilitation.

Purpose of the Study:

• To assess the feasibility and effectiveness of a low-cost virtual reality (VR) system integrated with partial body weight-supported treadmill training (BWSTT) for individuals post-stroke.
• To determine if this combined intervention can improve walking and balance abilities in patients with residual gait impairments.

Main Methods:

• A before-after study design was employed with a single group receiving the intervention.
• Participants included adults within one year post-stroke who had finished conventional therapy but still had gait deficits.
• The intervention consisted of twelve sessions of BWSTT incorporating a VR system that simulated walking environments and provided postural feedback.

Main Results:

• Six out of seven participants completed the study, indicating good feasibility.
• Significant improvements were observed in Functional Gait Assessment (FGA) scores (mean 13.8 to 18) and overground walking speed (mean 0.49 m/s to 0.68 m/s).
• Berg Balance Scale (BBS) scores also increased (mean 43.8 to 48.8), though a ceiling effect was noted for this measure.

Conclusions:

• The integration of a low-cost virtual reality system with partial body weight-supported treadmill training is a feasible and effective approach for enhancing gait and balance in stroke survivors.
• This combined therapy shows promise for improving functional mobility in individuals with persistent post-stroke impairments.
