Abstract
Ten PD patients and ten age-matched normal controls learned a sequence of 3 or 4 different hand movements to a criterion of 5 consecutive correct trials. They also performed a control sequence of 3 or 4 movements which involved the repetition of the same hand posture. Trials to reach criterion, errors, total response time and its components, response time for each movement and inter-response time were examined. There were no group differences in trials to criterion or errors. Total movement time as well as response and inter-response times were significantly longer for the PD patients, however, but only for sequences involving different hand movements not for the repetitive sequences. The relative timing of the responses was also different with the PD patients spending proportionately more time on each response and the controls spending more time between responses. The implications of these findings for understanding the movement sequencing impairments in PD are discussed.
