Abstract：
BACKGROUND: The subjective visual vertical (SVV) test can evaluate otolith function and spatial awareness and is performed in dedicated vertigo centers using specialized equipment; however, it is not otherwise widely used because of the specific equipment and space requirements. An SVV test smartphone app was developed to easily perform assessments in outpatient facilities.
OBJECTIVE: This study aimed to verify whether the SVV test smartphone app with commercially available virtual reality goggles can be used in a clinical setting.
METHODS: The reference range was calculated for 15 healthy participants. We included 14 adult patients with unilateral vestibular neuritis, sudden sensorineural hearing loss with vertigo, and Meniere disease and investigated the correlation between the SVV test results and vestibular evoked myogenic potential (VEMP) results.
RESULTS: The SVV reference range of healthy participants for the sitting front-facing position was small, ranging from -2.6º to 2.3º. Among the 14 patients, 6 (43%) exceeded the reference range for healthy participants. The SVV of patients with vestibular neuritis and sudden sensorineural hearing loss tended to deviate to the affected side. A total of 9 (64%) had abnormal cervical VEMP (cVEMP) values and 6 (43%) had abnormal ocular VEMP (oVEMP) values. No significant difference was found between the presence or absence of abnormal SVV values and the presence or absence of abnormal cVEMP and oVEMP values; however, the odds ratios (ORs) suggested a higher likelihood of abnormal SVV values among those with abnormal cVEMP and oVEMP responses (OR 2.40, 95% CI 0.18-32.88; P>.99; and OR 2, 95% CI 0.90-4.45; P=.46, respectively).
CONCLUSIONS: The SVV app can be used anywhere and in a short period while reducing directional bias by using virtual reality goggles, thus making it highly versatile and useful as a practical otolith dysfunction screening tool.

摘要：
背景：主观视觉垂直（SVV）测试可以评估耳石功能和空间意识，并在使用专门设备的专用眩晕中心进行；但是，由于特定的设备和空间要求，它不被广泛使用。开发了SVV测试智能手机应用程序，可以轻松地在门诊设施中进行评估。
目的：本研究旨在验证带有市售虚拟现实护目镜的SVV测试智能手机应用程序是否可用于临床环境。
方法：计算了15名健康参与者的参考范围。我们纳入了14例单侧前庭神经炎的成人患者，突然的感觉神经性听力损失伴眩晕,和梅尼埃病，并研究了SVV测试结果与前庭诱发肌源性电位（VEMP）结果之间的相关性。
结果：健康参与者坐前位置的SVV参考范围很小，范围从-2.6º到2.3º。在14名患者中，6（43％）超出了健康参与者的参考范围。前庭神经炎和突发性感觉神经性听力损失患者的SVV倾向于偏向患侧。共有9例（64％）的宫颈VEMP（cVEMP）值异常，6例（43％）的眼部VEMP（oVEMP）值异常。是否存在异常SVV值与是否存在异常cVEMP和oVEMP值之间没有显着差异；但是，比值比(OR)提示在cVEMP和oVEMP反应异常的人群中,SVV值异常的可能性较高(OR分别为2.40,95%CI0.18-32.88;P>.99;OR2,95%CI0.90-4.45;P=.46).
结论：SVV应用程序可以在任何地方和短时间内使用，同时通过使用虚拟现实护目镜减少方向偏差，因此，它具有高度的通用性和有用的实用耳石功能障碍筛查工具。
