Abstract

Patients with unilateral cerebral stroke and healthy controls were studied for limb and hemispatial hypometria. Subjects were required to reproduce lateral and medial horizontal displacements of each arm, with their eyes closed. Patients exhibited significant hypometria when moving toward hemispace contralateral to the lesion, and also when moving the limb contralateral to the lesion. Possible mechanisms for the hemispatial-limb hypometria are discussed.

摘要

对单侧脑卒中和健康对照者进行了肢体和半侧空间运动减少的研究。受试者被要求在闭眼状态下重现每只手臂的外侧和内侧水平位移。患者在向病变对侧半空间移动时，以及在移动病变对侧肢体时，均表现出明显的运动减少。文中讨论了半侧空间-肢体运动减少的可能机制。
