To explore the applicability of discrete wavelet transforms in the analysis of vHIT responses. Discrete wavelet transform was applied to vHIT responses and a new method for calculating aVOR gain was developed. A prospective study was performed with two groups of normal (N = 10) and altered (N = 19) gain values; HIMP and SHIMP vHIT protocols were performed on both groups. To evaluate the gain values obtained, Intraclass Correlation Index, Pearson's correlation, linear regression, and t test were performed. Intraclass correlation indexes of 0.97 and 0.99 were determined for HIMP and SHIMP procedures performed on the proposed and standard gain calculation method. A significant difference of - 0.06 ± 0.07 (p < 0.001) was found between gain calculation methods for HIMP protocol. Significant differences were found (p < 0.001) between normal and altered groups for all gain calculation methods. Discrete wavelet transforms were successfully applied to measure head impulse test responses. Gain values obtained with this method appear to be valid and in concordance with gain values obtained with standard calculation method. However, a slight but significant difference was observed when this method was applied to tests obtained with HIMP.
为探讨离散小波变换在视频头脉冲试验（vHIT）反应分析中的适用性。将离散小波变换应用于vHIT反应，并开发了一种计算视动性眼震（aVOR）增益的新方法。对两组增益值正常（N = 10）和异常（N = 19）的受试者进行了一项前瞻性研究；两组均进行了头脉冲试验和正弦谐波加速试验（HIMP和SHIMP）vHIT方案。为评估获得的增益值，进行了组内相关指数、Pearson相关性、线性回归和t检验。在所提出的增益计算方法和标准增益计算方法上进行的HIMP和SHIMP程序的组内相关指数分别为0.97和0.99。在HIMP方案的增益计算方法之间发现了-0.06±0.07的显著差异（p < 0.001）。在所有增益计算方法中，正常组和异常组之间均发现了显著差异（p < 0.001）。离散小波变换成功应用于测量头脉冲试验反应。用该方法获得的增益值似乎是有效的，并且与用标准计算方法获得的增益值一致。然而，当该方法应用于通过HIMP获得的测试时，观察到了轻微但显著的差异。
