The clinical utility of cervical and ocular vestibular-evoked myogenic potential (cVEMP and oVEMP) is limited by variability of testing protocols and a dearth of normative data using contemporary methods for amplitude scaling.
AIMS/OBJECTIVES: To investigate the effect of body position and electrode montage on VEMP responses and to establish normative values.
This is a repeated measures study of 44 healthy young adult subjects (22 men and 22 women).
The highest response rate (99%) for cVEMP was achieved in the supine position with the head elevated and turned. For oVEMP, the highest response rate (90%) was achieved using nasal alar electrode montage with the subject in a sitting position. Scaled peak-to-peak amplitude was higher in males than in females for both cVEMP and oVEMP.
Normative data for 44 young healthy adults was successfully collected for two body positions for cVEMP and two head positions and two electrode montages for oVEMP.
Our findings describe VEMP protocols that efficiently detect VEMP responses, and we provide normative VEMP response data for young healthy subjects. We describe a potential difference in response between males and females, which may be clinically important.
由于测试方案的变异性以及缺乏使用当代振幅标度方法的规范数据，颈椎和眼性前庭诱发肌源性电位（cVEMP 和 oVEMP）的临床实用性受到限制。
研究体位和电极放置对 VEMP 反应的影响，并建立正常值。
这是一项对 44 名健康年轻成年受试者（22 名男性和 22 名女性）的重复测量研究。
在仰卧位头部抬高和转动时，cVEMP 的最高反应率（99%）最高。对于 oVEMP，在受试者坐位时使用鼻侧耳甲电极放置，最高反应率（90%）最高。cVEMP 和 oVEMP 的峰值到峰值振幅在男性中均高于女性。
成功为 cVEMP 的两种体位和 oVEMP 的两种头位和两种电极放置方式收集了 44 名年轻健康成年人的正常值数据。
我们的研究结果描述了能够有效检测 VEMP 反应的 VEMP 方案，并为年轻健康受试者提供了正常的 VEMP 反应数据。我们描述了男性和女性之间反应的潜在差异，这可能具有临床意义。
