Effects of Virtual Reality and Otago Exercises in Parkinson's Disease Patients.

The second most prevalent neurological condition is Parkinson disease. It impairs motor function, gait, balance, and daily living tasks. More advanced therapies that target balance, gait, and activities of daily living are required. Virtual reality helps in cognitive and motor improvement by creating a virtual environment. While otago exercise helps to improve balance and coordination and reduce the risk of falls in Parkinson patients. Virtual reality and otago exercises may help to improve balance and gait by providing sensory feedback that will help in motor learning and relearning. This study will compare the effects of virtual reality and otago exercises on balance, gait, and activities of daily living in patients with Parkinson's disease. This randomized clinical trial will be carried out in a study setting 10 months after the approval of synopsis. In this study, 74 participants who will meet inclusion criteria through a non-probability convenience sampling technique will be included. Participants will be randomly assigned into 2 groups using online research randomizer software. Group A and Group B participants will receive Otago exercises and virtual reality, respectively. Total treatment time will be 25 minutes. The outcome measuring tools used will be Berg balance scale for static balance and time-up and go to measure dynamic balance; a 6-minute walk test will be used for gait, and Unified Parkinson disease Rating scale for activities of daily living. Kolmogorv-Smirnov test will be used to check normality of data. If data will be normally distributed, a one-way ANOVA will be used, and for non-parametric data, the Kruskal-Wallis test will be used. Type (Exercises): Weeks 1-2: Foundation and Familiarization Balance Exercises: Start with basic static balance tasks (e.g., standing on one leg, weight shifting) within a VR environment. Gait preparation: introduce walking simulations on level ground to familiarize participants with VR-based gait training. ADL Simulation: Initiate simple ADL tasks in VR, such as reaching for objects or virtual button pressing. Weeks 3-4: Balance and Coordination Development * Dynamic Balance: Progress to dynamic balance exercises (e.g., stepping over virtual obstacles, balancing on unstable surfaces in VR). * Coordination Training: Incorporate dual-task activities where participants perform balance exercises while engaging in cognitive tasks within the VR environment. * Functional ADLs:
