Abstract

Background: Frequency tuning of ocular vestibular evoked myogenic potential (oVEMP) refers to the frequency of tone burst that produces the largest amplitude oVEMP. There is an ever-growing pool of published studies that found the frequency tuning of oVEMP distinctly different in Ménière's disease than the age-matched controls and benign paroxysmal positional vertigo. However, recording oVEMP in response to many frequencies makes an already lengthy vestibular test battery even more cumbersome and time-consuming.

Purpose: The aim of this study was to develop a novel time-saving stimulus that produces reliable results.

Research design: Prospective study.

Study sample: The study included 25 young, healthy adults.

Data collection: The tone-bursts of 2000, 1500, 1000, 750, 500, and 250 Hz were generated and sequenced in this order to prepare a stimulus for simultaneous multifrequency (SiMFy) oVEMP. The response parameters of SiMFy and conventional oVEMP methods were compared.

Results: No significant difference in peak-to-peak amplitude and frequency tuning existed between conventional and SiMFy oVEMP (p > 0.05). SiMFy had better test-retest reliability and was less time-consuming than the conventional oVEMP.

Conclusions: SiMFy is a time-saving and reliable stimulus for obtaining frequency tuning of oVEMP with no compromise on the outcomes. It can be immediately applied in most commercially available evoked potential systems with a facility for loading an external stimulus.

同时多频(SiMFy)刺激:一种新的、可靠的眼球前庭诱发肌源性电位频率调节刺激。

背景:眼球前庭诱发肌电位(oVEMP)频率调谐是指产生最大振幅oVEMP的张力爆发频率。越来越多的已发表的研究发现，与年龄匹配的对照组和良性发作性体位性眩晕相比，在mims病中oVEMP的频率调节明显不同。然而，记录oVEMP对许多频率的响应使得已经很长的前庭测试电池更加麻烦和耗时。目的:本研究的目的是开发一种新的省时刺激，产生可靠的结果。研究设计:前瞻性研究。研究样本:该研究包括25名年轻健康的成年人。数据收集:产生2000、1500、1000、750、500和250 Hz的音暴并按此顺序排序，为同步多频oVEMP (SiMFy)准备刺激。比较了SiMFy法和常规oVEMP法的响应参数。结果:常规与SiMFy oVEMP在峰间振幅和频率调谐方面无显著差异(p > 0.05)。与传统的oVEMP相比，SiMFy具有更好的重测可靠性和更少的时间。结论:SiMFy是一种省时、可靠的获得oVEMP频率调谐的刺激，且不影响结果。它可以立即应用于大多数商业上可用的具有加载外部刺激设施的诱发电位系统。
