Introduction: Dizziness is a common complaint affecting up to 23% of the world population. Diagnosis is of utmost importance and routinely involves several tests to be performed in specialized centers. The advent of a new generation of technical devices would make envision their use for a valid objective vestibular assessment. Microsoft HoloLens 2 (HL2) mixed reality headset has the potential to be a valuable wearable technology that provides interactive digital stimuli and inertial measurement units (IMUs) to objectively quantify the movements of the user in response to various exercises. The aim of this study was to validate the integration of HoloLens with traditional methods used to analyze the vestibular function in order to obtain precise diagnostic values. Methods: Twenty-six healthy adults completed the Dynamic Gait Index tests both with a traditional evaluation and while wearing HL2 headset, thus allowing to collect kinematic data of the patients’ head and eyes. The subjects had to perform 8 different tasks, and the scores were independently assigned by two otolaryngology specialists. Results: The maximum of the mean position of the walking axis of the subjects was found in the second task (−0.14 ± 0.23 m), while the maximum value of the standard deviation of the walking axis was found in the fifth task (−0.12 ± 0.27 m). Overall, positive results were obtained in regard to the validity of the HL2 use to analyze kinematic features. Conclusion: The accurate quantification of gait, movement along the walking axis, and deviation from the normality using HL2 provide an initial evidence for its useful adoption as a valuable tool in gait and mobility assessment.

前庭评估中的增强虚拟现实：动态步态应用

简介：头晕是一种常见疾病，影响着世界上多达 23% 的人口。诊断至关重要，通常需要在专门中心进行多项测试。新一代技术设备的出现将有望用于有效的客观前庭评估。Microsoft HoloLens 2 (HL2) 混合现实耳机有潜力成为一种有价值的可穿戴技术，它提供交互式数字刺激和惯性测量单元 (IMU)，以客观量化用户响应各种锻炼的动作。本研究的目的是验证 HoloLens 与用于分析前庭功能的传统方法的集成，以获得精确的诊断值。方法： 26 名健康成年人通过传统评估和佩戴 HL2 耳机完成了动态步态指数测试，从而收集患者头部和眼睛的运动数据。受试者必须执行 8 项不同的任务，分数由两名耳鼻喉科专家独立分配。结果：受试者行走轴的平均位置最大值出现在第二个任务中（-0.14±0.23 m），而行走轴标准差的最大值出现在第五个任务中（-0.12 ± 0.27 m）。总体而言，关于使用 HL2 分析运动学特征的有效性，获得了积极的结果。结论：使用 HL2 对步态、沿行走轴的运动以及与正常状态的偏差进行准确量化，为其作为步态和活动评估中的有价值工具的有用采用提供了初步证据。
