Comparison of Different Rehabilitation Protocols in Parkinson's Disease With Postural Instability and Gait Disorders

"Increasingly difficult gait and balance exercises up to include dual-task. During each training session, four exercises (5 minutes of execution, two times each) will be proposed. Patients will observe a 2-minute video clip showing a balance or gait task (action observation - AOT) and will imagine the same exercise (motor-imagery - MI) before task execution. Each training session will be proposed with the following modality: 2 minutes of AOT - 5 minutes of task execution - 2 minutes of MI - 5 minutes of task execution. Patients will be explicitly asked to concentrate on how the actions are performed in the videos and to carefully use MI to improve their motor performance. Patients will not be allowed to perform any movement while watching videos or during MI.~1 hour, 3 times a week for six weeks."
