Abstract

The purpose of this study is to examine if PD (Parkinson disease) patients present a deficit in procedural motor learning. A portable robotic device is being used to generate forces that disturb subjects' arm movements. Patients and age-matched controls have to learn to manipulate this "virtual mechanical environment." Our preliminary results suggest that, indeed, PD patients present a deficit in the rate of procedural motor learning, particularly in presence of "novelty."
