Abstract
Event-related desynchronization (ERD) and Event-related synchronization (ERS) during voluntary self paced thumb movement were measured in patients suffering from idiopathic Parkinson's disease and compared to an age-matched control group. Twenty-three electrodes were located at equidistant intervals over central, parietal and frontal regions. Several frequency bands in the range of 6-30 Hz were analyzed. ERD was found to be larger and more widespread in patients with Parkinson's disease (PD) as compared to control subjects. Furthermore concerning the post-movement beta synchronization, ERS was decreased in patients as compared to controls. While in the control group a large ERS was found over the contralateral central region after movement offset, patients with PD showed a very small post-movement ERS ipsi- as well as contralateral to movement.
