Here we review the clinical value of a video-oculography test for clinical evaluation of vestibular otolith function. This test is known as the video ocular counter roll (vOCR) and is based on measurement of torsional vestibulo-ocular reflex with a lateral head tilt. The vOCR test consists of a simple maneuver during which the head and torso are tilted en bloc by the examiner. The pattern of vOCR deficit among patients highlights its clinical value in identifying the stage of vestibular loss and recovery. The quick application of vOCR allows examination of otolith-ocular function and assessment of vestibular recovery at the bedside.
在这里，我们回顾了视频眼震描记术测试在评估前庭耳石功能中的临床价值。该测试称为视频眼震counter roll（vOCR），基于头部侧倾时扭转前庭眼反射的测量。vOCR 测试由一个简单的动作组成，在这个动作中，检查者整块地倾斜头部和躯干。患者 vOCR 缺损的模式突出了其在识别前庭损失和恢复阶段方面的临床价值。vOCR 的快速应用允许在床边检查耳石眼动功能和评估前庭恢复。
