  Purpose

We are testing a computer game-style rehabilitation program for people with Parkinson's disease (PD). People with PD often have difficulty with motor planning, such as initiating or starting movements. We believe that our program will improve performance on a movement initiation task as well as on activities of daily living, such as walking, preparing a meal or opening a medicine bottle. We will measure brain function using functional MRI before and after training to identify brain areas that are involved in improved performance. If effective, computer based training will be an inexpensive treatment for motor planning deficits in PD that is free from side effects and easy to administer to a large number of patients.

Arms Assigned Interventions
Experimental: Arm 1
PD subjects
Behavioral: PC based training
Subjects sit at a computer and type a string of numbers that appears on the screen. They are then instructed to repeat the string from memory. As performance improves (# correct), the strings of numbers get longer.

Detailed Description:

Our approach is to use PD-based adaptive training to improve performance on IG movement initiation in patients with PD. We have three aims, 1) to systematically evaluate cognitive rehabilitation in people with Parkinson's disease (PD), 2) to examine the neural mechanisms subserving cognitive rehabilitation in PD and 3) to assess the ecological validity of cognitive rehabilitation in PD. We will focus on a single aspect of cognitive function, the decision to initiate a movement. Movements can be internally generated (IG) or externally cued, and motor deficits in PD are typically linked to IG movements. The protocol is designed to drive beneficial neuroplastic changes using a paradigm similar to those that have shown promising results in traumatic brain injury patients. In addition, we will use fMRI to measure activity in underlying basal ganglia-thalamocortical circuits. Finally, because the goal of any research regarding the pathophysiology of disease is to improve the lives of patients with the disease, behavioral and neuropsychological measures will be correlated with fMRI measured functional abnormalities before and after training. Improvement in the initiation of movement has the potential to dramatically improve daily functioning including reducing falls, improving language production and improving proficiency of activities of daily living.
