Collaborative vs Non-Immersive VR in Parkinson's Rehabilitation

This randomized controlled trial aims to compare the effectiveness of a Collaborative Virtual Reality Environment (CVE) and Non-Immersive Virtual Reality (NIVR) in the rehabilitation of patients with Parkinson's disease. Participants with mild to moderate disease severity will be randomly assigned to either the CVE group or the NIVR group. The CVE intervention will involve therapist-guided, interactive virtual exercises in a shared environment, promoting real-time engagement and feedback. The NIVR group will perform task-oriented exercises using screen-based virtual reality without immersive and collaborative features. Both interventions will be delivered over an 12-week period. Primary outcomes will assess motor function using standardized clinical scales, while secondary outcomes will evaluate cognitive function, mobility, and quality of life. The study seeks to determine whether collaborative and interactive virtual rehabilitation provides superior clinical outcomes compared to conventional non-immersive virtual approaches in patients with Parkinson's disease.
