Normative values for semicircular canal function with the video head impulse test (vHIT) in healthy adolescents

Abstract

Background

The vHIT device, which has a mechanism based on measuring the VOR gain, helps us to quickly evaluate six semicircular canals.

Aims/Objectives

The aim of this study was to establish normative values for semicircular canal function with the video head impulse test (vHIT) battery in normal adolescents.

Material and methods

100 (50 females, 50 males) individuals aged 11–18 years, with a mean age of 14.99 years, were included in the study.

Results

As a result of the vHIT evaluations performed with vHIT Otometrics ICS Impulse A/S Taastrup, Denmark, the mean lateral canal vestibulo-ocular reflex (VOR) gain value was 0.96, the mean anterior canal VOR gain value was 0.89, and the mean posterior canal VOR gain value was 0.87, all of which were within the normal value range.

Conclusion and significance

While the VOR gain values and asymmetry values are within the normal value range and are similar to the literature, no statistically significant correlation was observed between these values and age. As a result, the vHIT battery is an easy, fast, and practical test method that can be used in adolescents.

背景：vHIT设备具有基于测量VOR增益的机制, 可帮助我们快速评估六个半规管。

目的：本研究的目的是通过视频头冲测试（vHIT）电池来确定正常青少年半规管功能的标准值。

资料和方法：本研究共纳入100个人（女性50位, 男性50位）。年龄范围为11至18岁, 平均年龄为14.99岁。

结果：通过丹麦vHIT Otometrics ICS Impulse A / S Taastrup进行vHIT评估。其结果是, 平均外侧管前庭眼反射（VOR）增益值为0.96, 平均前管VOR增益值为0.89, 后路平均VOR增益值为0.87, 均在正常值范围内。

结论和意义：尽管VOR增益值和不对称值在正常值范围内, 并且与文献相似, 但在这些值和年龄之间未观察到统计学显著相关性。因此, vHIT电池是一种可以在青少年中使用的简便、快速且实用的测试方法。
