This study is comparing two types of physical therapy for people with Parkinson's disease, a condition that affects movement and balance. *Parkinson's* causes symptoms like slow movements, stiffness, and tremors. **Virtual reality (VR) therapy** uses computer-based exercises, while **conventional therapy** involves traditional exercises with a therapist. Participants will be split into two groups by chance. One group will try VR therapy, and the other will do conventional therapy. They will do exercises three times a week for eight weeks. Before and after the sessions, researchers will check how well participants can move and do daily tasks. **Key Points:** - The study lasts about 9 months with 24 therapy sessions over 8 weeks. - Participants should be aged 45-65 with Parkinson’s disease, but not have other neurological issues or recent surgeries. - Safety measures are in place, and participation is voluntary with no penalty for withdrawal. This research might help find out if VR therapy can be as good or better than regular therapy for improving movement in Parkinson's patients.
