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

    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.

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 weeks
2

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 weeks
3

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 weeks

Secondary 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 weeks
2

Change in gait speed

Assessed with the 10-Meter Walk Test. Faster walking speed indicates better gait performance.

Time frame
Baseline and 8 weeks
3

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.

Time frame
Baseline and 8 weeks
