在视觉引导下进行的手的物体运动障碍(视性共济失调)是后分水岭区域双侧局限性脑梗塞患者的显著症状。该征象被解释为全景视觉信息与上肢本体感觉信息的缺陷整合所致，并与顶枕交界处的结构受损或其神经流出至运动前区域有关。
Impairment of object-bound movements of the hand performed under visual guidance (optic ataxia) was a prominent sign in a patient with bilateral circumscribed infarctions in the posterior watershed territory. The sign was interpreted as resulting from defective integration of panoramic visual information with proprioceptive information concerning the upper extremity, and as being related either to damage of structures in the parietooccipital junction or their neural outflow to the premotor region.
