Head oscillations and eye movements when stepping and running were studied in normal subjects and in patients with labyrinthine dysfunctions. In normal subjects, whereas linear head oscillations in the horizontal plane were very limited during both stepping and running, a marked increase in the vertical linear displacement induced pitching motions of the head during running. Patients with unilateral and bilateral lesions complaining of oscillopsia manifested lateral and diffuse oscillations, respectively, in the horizontal plane during stepping. The ratio of eye amplitude to head amplitude in the vertical plane showed larger values in subjects with labyrinthine lesions than in normals. The present results suggested that oscillopsia during upright locomotion is closely related to linear head oscillations with irregular and high-frequency components, in addition to dysfunction of the vestibulo-ocular reflex.
研究了正常受试者和患有迷路功能障碍的患者在行走和跑步时的头部摆动和眼球运动。在正常受试者中，虽然在行走和跑步过程中水平面上的线性头部摆动非常有限，但跑步时垂直线性位移的显著增加会引起头部的俯仰运动。抱怨视振荡的单侧和双侧病变患者在行走时分别在水平面上表现出侧向和弥漫性振荡。垂直平面上眼球振幅与头部振幅的比值在患有迷路病变的受试者中比正常人更大。目前的结果表明，直立运动时的视振荡除了与前庭眼反射功能障碍有关外，还与具有不规则和高频成分的线性头部摆动密切相关。
