Virtual Reality Verses Conventional Physical Therapy in Parkinson's Disease Patients

ntervention Description - Conventional Physical Therapy Conventional physical therapy consists of therapist-guided exercises aimed at improving balance, gait, strength, and functional mobility in individuals with Parkinson's disease. Each session includes a warm-up, structured balance training (anticipatory, reactive, and sensory strategies), overground gait training with cueing techniques, lower-limb and core strengthening exercises, and a cool-down period with stretching and fall-prevention education. Treatment is delivered by licensed physiotherapists three times per week for eight weeks, with exercise difficulty progressively adjusted according to individual performance and tolerance.

Intervention Description - Virtual Reality-Based Physical Therapy Virtual reality-based physical therapy uses interactive computer-generated environments to provide task-specific balance and gait training with real-time visual and auditory feedback. Participants perform activities such as weight shifting, stepping to virtual targets, obstacle negotiation, and dynamic walking tasks designed to challenge postural control and mobility. Sessions are supervised by trained physiotherapists and delivered three times per week for eight weeks. Task difficulty is progressively increased based on participant performance, with safety measures in place throughout the intervention.
