Abstract

The kinematic organization of a reach to grasp movement in a left hemiParkinson subject is compared to that of a control subject. Subjects used the right and left limbs to reach 15, 27 or 40 cm for the grasp of cylinders of 0.7 or 8 cm diameter. In general, the kinematics of the affected limb of the hemiParkinson subject differed from that of the unaffected limb. However, for both arms the hemiParkinson subject showed a delay in the onset of the manipulation component. The subtle dysfunction in the activation of near-simultaneous or sequential movements is thus bilateral, despite unilateral clinical symptomatology.

摘要

将一名左半侧帕金森病患者抓握动作的运动学组织与一名对照受试者的进行比较。受试者使用右肢和左肢去够取15厘米、27厘米或40厘米远的物体，以抓握直径为0.7厘米或8厘米的圆柱体。总体而言，半侧帕金森病患者患侧肢体的运动学与未受影响肢体不同。然而，对于双臂而言，半侧帕金森病患者在操作部分的起始阶段都出现了延迟。因此，尽管存在单侧临床症状，但近乎同时或连续运动激活方面的细微功能障碍是双侧性的。
