Abstract:
Determination of the normative data of Vestibulo-Ocular Reflex gain using VHIT of all three semicircular canals (anterior, posterior, horizontal) on both sides in different age groups is of interest. This is an observational study comprised of 10 healthy individuals in each decade from less than 10 years to 80 years of both sexes making a total of 80. The study was done using the equipment SYNAPSYS VHIT ULMER with Software EVOLUTION 3.0. Mean VOR gain of each decade for all the semicircular canals is calculated and they are compared using ANOVA (Analysis of variance). In our study, percentage of patients with overt saccades is nil. Hence, in our study, the occurrence of covert saccades was insignificant as compared to the above studies. Age dependent VOR gain in normal individuals did not have any significance in our study of 80 patients performed by video head impulse test. VOR gain in our study is not affected by age. Normative data for different age groups obtained compared among different age groups showing no significant difference in Mean VOR gain. The normative values of VOR gain can be compared to patients with dizziness thus helping in determining any vestibular loss.
摘要:
使用所有三个半规管的VHIT确定前庭眼反射增益的规范数据(前,后部,横向)对不同年龄组的两边都感兴趣。这是一项观察性研究,由10名健康个体组成,每十年从不到10年到80岁,男女共80人。本研究使用带有软件EVOLUTION3.0的SYNAPSYSVHITULMER设备进行。计算所有半规管的每十年的平均VOR增益,并使用ANOVA(方差分析)比较它们。在我们的研究中,明显扫视的患者百分比为零。因此,在我们的研究中,与上述研究相比,隐性扫视的发生微不足道。在我们通过视频头脉冲测试对80例患者进行的研究中,正常人的年龄依赖性VOR增加没有任何意义。在我们的研究中,VOR的增加不受年龄的影响。在不同年龄组之间比较获得的不同年龄组的规范数据显示,平均VOR增加没有显着差异。可以将VOR增益的标准值与头晕患者进行比较,从而有助于确定任何前庭损失。
