Effect of Virtual Reality-Based Music Therapy on Cognitive and Motor Skills in Subacute Stroke Patients

Effect of Immersive Virtual Reality-Based Music Therapy on Cognitive and Motor Skills in Subacute Stroke Patients

This clinical trial aims to investigate the effects of immersive virtual reality-based music therapy on cognitive and motor functions in individuals aged 50 to 75 years with subacute stroke (between 2 weeks and 6 months post-stroke). Participants will be randomly assigned to either a control group receiving conventional physiotherapy or an experimental group receiving conventional physiotherapy plus virtual reality-based music therapy.

The study will assess cognitive performance, upper extremity motor skills, stroke impact, balance, and spatial neglect before and after a 6-week intervention. All participants will be treated at Istanbul Aydın University VM Medical Park Hospital. The study has been approved by the ethics committee, and written informed consent will be obtained from all participants.

This is a single-center, single bilind, randomized, controlled, prospective clinical trial designed to evaluate the effects of immersive virtual reality (VR)-based music therapy on cognitive functions, upper extremity motor skills, stroke impact, balance, and spatial neglect in patients with subacute stroke. The study targets individuals aged between 50 and 75 years who have experienced a stroke within the previous 2 weeks to 6 months. All participants will be recruited from Istanbul Aydın University VM Medical Park Hospital.

Participants will be stratified based on the side of hemispheric damage (right or left) and randomized into two equal groups (n=15 per group). The control group will receive conventional physiotherapy and rehabilitation 5 days per week for 6 weeks. The experimental group will receive the same conventional physiotherapy program along with additional immersive VR-based music therapy sessions twice a week. These VR sessions involve rhythm-based and music-supported tasks delivered through Oculus Quest 2 applications, including Ocean Rift and PianoVision.

Assessments will be performed at baseline and after the 6-week intervention period. Cognitive function will be assessed using standardized neuropsychological tools, and motor function will be evaluated through established stroke motor recovery scales. The Virtual Reality Sickness Questionnaire (VRSQ) will be administered after the first VR session to monitor adverse effects such as dizziness or nausea.

This trial adopts a stratified randomization method to enhance internal validity by balancing brain hemisphere involvement across groups. A power analysis conducted using G*Power (version 3.1) determined a sample size of 30 participants based on an effect size reported by Fan et al. (2024), with 95% power and α=0.05. The study protocol has been approved by the Non-Interventional Research Ethics Committee of Üsküdar University (Approval No: 61351342/020-1000, Date: March 27, 2025). Written informed consent will be obtained from all participants before enrollment.
