由于临床环境中缺乏床边措施，前庭丧失后的恢复评估受到限制。本研究采用视频眼反侧滚（vOCR）试验，研究前庭功能丧失不同阶段患者的耳石-眼功能及颈部本体感觉的代偿作用。病例对照研究。三级护理中心。招募了五十六例受试者，包括急性（9 ± 2天[平均值±平均值的标准误差]）、亚急性（61 ± 11天）和慢性（1009 ± 266天）单侧前庭功能丧失的患者，以及一组健康对照。我们使用了一种基于跟踪虹膜的视频眼电方法进行vOCR测量。为了检查颈部输入的影响，在所有受试者坐着时进行两个简单的倾斜动作时记录了vOCR：头对身体倾斜30°和头对身体倾斜30°。vOCR反应在前庭丧失后的不同阶段演变，在慢性阶段获得改善。当整个身体倾斜时，（急性：0.08 ± 0.01，亚急性：0.11 ± 0.01，慢性：0.13 ± 0.02，健康对照：0.18 ± 0.01），并且当头部倾斜于身体时，vOCR的增益增加（急性：0.11 ± 0.01，亚急性：0.14 ± 0.01，慢性：0.13 ± 0.02，健康对照：0.17 ± 0.01）。vOCR反应的时程也受到影响，在前庭丧失的急性期，振幅降低，反应较慢。vOCR测试可以作为一个有价值的临床指标，以衡量前庭功能丧失后的不同阶段的患者的前庭恢复和颈部本体感觉的代偿作用。
Assessment of recovery following vestibular loss has been limited by the lack of bedside measures in clinical settings. Here, we used the video ocular counter-roll (vOCR) test to study otolith-ocular function and compensatory effect of neck proprioception in patients at different stages of vestibular loss. Case-control study. Tertiary care center. Fifty-six subjects were recruited including patients with acute (9 ± 2 days [mean ± standard error of mean]), subacute (61 ± 11 days), and chronic (1009 ± 266 days) unilateral loss of vestibular function, as well as a group of healthy controls. We used a video-oculography method based on tracking the iris for vOCR measurement. To examine the effect of neck inputs, vOCR was recorded during two simple tilt maneuvers in all subjects while seated: 30° head-on-body tilt and 30° head-and-body tilt. The vOCR responses evolved at different stages following vestibular loss with improvement of the gains in the chronic stage. The deficit was more pronounced when the whole body was tilted (acute: 0.08 ± 0.01, subacute: 0.11 ± 0.01, chronic: 0.13 ± 0.02, healthy control: 0.18 ± 0.01), and the gain of vOCR improved when the head was tilted on the body (acute: 0.11 ± 0.01, subacute: 0.14 ± 0.01, chronic: 0.13 ± 0.02, healthy control: 0.17 ± 0.01). The time course of vOCR response was affected as well with reduced amplitude and slower response in the acute stage of vestibular loss. The vOCR test can be valuable as a clinical marker to measure vestibular recovery and compensatory effect of neck proprioception in patients at different stages following loss of vestibular function.
