About this trial
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.

Treatments tested in this trial
Supervised In-Center Eye Exercises
BehavioralThe 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.

Trial outcomes
Primary outcomes
1
Change in physical function
Assessed with the 6-Minute Walk Test. Greater distance indicates better physical function and walking endurance.
Time frame
Baseline and 8 weeks2
Change in dynamic balance
Assessed with the Mini-BESTest total score. Higher scores indicate better dynamic balance and postural control.
Time frame
Baseline and 8 weeks3
Change in fall-related concern
Assessed with the Falls Efficacy Scale-International (FES-I). Higher scores indicate greater concern about falling.
Time frame
Baseline and 8 weeksSecondary outcomes
1
Change in functional mobility
Assessed with the Timed Up and Go test. Shorter completion times indicate better mobility.
Time frame
Baseline and 8 weeks2
Change in gait speed
Assessed with the 10-Meter Walk Test. Faster walking speed indicates better gait performance.
Time frame
Baseline and 8 weeks3
Change in lower-limb functional strength
Assessed with the 30-second sit-to-stand test. More repetitions indicate better lower-limb functional strength and endurance.
