Abstract:
15 parkinsonian patients with mainly unilateral symptoms (right side 10, left side 5) were studied in a decision reaction time (DRT) experiment in which the performance of the more affected hand was compared with that of the less affected hand. Decision time (DT) was longer in the more affected hand, however, the movement time (MT) did not differ between the two hands. In conclusion, slowness of movement in complex reaction response in Parkinsonian patients may be attributable to the defect of premovement central neural processing related to motor planning.
