当绕着鼻枕轴滚动倾斜时，由于扭转前庭眼反射，人类表现出眼睛在相反方向上的补偿性扭转旋转。在静态条件下（持续的头部滚动），椭圆囊作为“静态眼反滚动”的负责传感器。颈眼反射的贡献仍然未知。为了找到一个简单的，临床上有用的测试椭圆囊功能，我们诱导10名健康的研究参与者（两名男性，平均年龄27 +/- 2岁）在三种刺激条件下（主动/被动头部倾斜和被动全身倾斜滚动平面），使用三维视频眼电图来测量它，并比较值。主动头倾斜引起的眼球反滚变化最大，因此比被动头和身体倾斜引起的眼球反滚更不可靠。因此，通过视频眼电图测量被动头部倾斜可以简单地测试椭圆囊功能。(c)2006年利平科特威廉姆斯&威尔金斯。
When roll-tilted around the naso-occipital axis, humans exhibit compensatory torsional rotation of the eyes in the opposite direction owing to the torsional vestibulo-ocular reflex. In the static condition (sustained head roll), the utricles act as responsible sensors for 'static ocular counterroll'. Contributions of cervico-ocular reflexes remain unknown. To find an easy, clinically useful test of utricular function, we induced ocular counterroll in 10 healthy study participants (two men, mean age 27 +/- 2 years) under three stimulation conditions (active/passive head tilt and passive whole body tilt in roll plane), used three-dimensional video-oculography to measure it, and compared values. Active head-tilt-induced ocular counterroll varied most and was thus less reliable than passive head and body tilt-induced ocular counterroll. Utricular function can thus be tested simply by measuring passive head tilt with video-oculography. (c) 2006 Lippincott Williams & Wilkins.
