摘要: This study assesses the reach to grasp movement of eight Parkinson and control subjects. The was either 15, 27.5 or 40 cm. a small (0.7 cm) large diameter (8 dowel. When comparing subjects, no differences were found in regulation parameters according changes object distance size. However, for Parkinson's disease patients onset manipulation component delayed with respect transport component. It is proposed that this reflects deficit simultaneous sequential implementation different segments complex movement.
