Effects of self-directed game-based virtual reality program on upper-limb motor recovery in mild-to-moderate ischemic...

Area of Science:

• Neurorehabilitation
• Digital Health
• Stroke Recovery

Background:

• Virtual reality (VR) shows promise for post-stroke motor recovery.
• Self-directed VR training can reduce staffing needs but requires safety and efficacy validation.

Purpose of the Study:

• To assess the effectiveness of a self-directed, game-based VR program for upper-limb motor recovery in patients with mild-to-moderate ischemic stroke.

Main Methods:

• A randomized controlled trial involving 84 mild-to-moderate ischemic stroke patients.
• Participants received standard rehabilitation; the VR group had additional VR training, the control group had conventional training for 4 weeks.

Main Results:

• The VR group showed significant improvements in upper-limb function (FMA-UE) and strength compared to controls.
• More VR patients achieved clinically meaningful improvements (FMA-UE MCID).
• The VR program demonstrated high usability, safety (minimal simulator sickness), and patient motivation.

Conclusions:

• Integrating self-directed VR games enhances upper-limb recovery and independence in stroke patients.
• The VR program provides clinically meaningful and sustained benefits, especially for moderate impairments.
• VR is a safe, engaging, and scalable option for inpatient stroke rehabilitation.
