We measured arm movement on the sagittal plane of parietal lobe damaged patients and control subjects. In neurological patients, (1) the hand height did not become lower as the motion duration became shorter; (2) the hand jerk of measured trajectory increased when motion duration lengthened. These results suggested that the parietal lobe is involved with realizing smooth arm movement. The performance of patients with parietal lobe lesions may reflect their difficulties in planning a trajectory with smooth movement.
