Interventions

  • Supervised In-Center Eye Exercises — BEHAVIORAL
    The participants in the study group will perform the eye-exercise program in a supervised rehabilitation/clinic setting. The exercises will initially be performed in a seated position, with selected tasks progressed to standing positions as tolerated and considered safe by the supervising therapist. The exercises will be administered face-to-face by trained study personnel. The program will include progressive visual fixation, smooth pursuit, saccadic eye movements, convergence/divergence, gaze stabilization, and combined eye-head coordination tasks, with gradual progression in speed and complexity according to participant tolerance and safety.

Study Details

Parkinson's disease is commonly associated with impaired gait, postural instability, reduced physical function, and increased concern about falling, all of which contribute substantially to disability and reduced quality of life. Exercise-based rehabilitation is increasingly recommended as a core non-pharmacological strategy for improving mobility and balance in people with Parkinson's disease. In parallel, recent clinical and neurorehabilitation research suggests that eye-movement and gaze-stabilization training may influence postural control, visuomotor integration, and movement performance in neurological disorders, including Parkinson's disease. This randomized controlled trial will evaluate whether a supervised in-center eye-exercise program can improve physical function, balance, and fall-related concern in patients with Parkinson's disease.

Arms

  • Experimental: Supervised In-Center Eye Exercise Group
    Participants will receive a structured eye-exercise program designed to train oculomotor control, gaze stability, and eye-head coordination. The program will be delivered face-to-face in the center during supervised sessions. Each session will last approximately 30 to 45 minutes, 3 sessions per week for 8 weeks.
  • No Intervention: Control group
    Participants allocated to the control arm will receive standard neurological care and routine advice to maintain their usual daily activities. They will not receive the structured eye-exercise program during the intervention period.
