To explore the dynamic changes of vestibular autorotation test (VAT) before and after vestibular rehabilitation treatment in patients with unilateral vestibular hypofunction (UVH). A retrospective study was carried out,48 patients who were diagnosed with UVH and under vestibular rehabilitation in department of otorhinolaryngology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2019 to January 2021 were enrolled. Among them, there were 21 males and 27 females, with an average age of 46.9 years old, including 25 cases of Meniere's disease, 13 cases of sudden deafness with vertigo and 10 cases of vestibular neuritis. The course of disease ranged from 5 days to 10 years. Demographic characteristics, detailed case data and routine examination were collected for the patients. The horizontal gain/phase, vertical gain/phase, and asymmetry of VAT at different frequencies before and after vestibular rehabilitation were collected. The absolute value of the difference between the measured value of 2.0-5.9 Hz before and after rehabilitation and the standard value were statistically analyzed. Before vestibular rehabilitation, the incidence of abnormal gain was 62.5% (30/48), the incidence of abnormal phase was 56.3% (27/48), and the incidence of asymmetry was 16.7% (8/48). After 4-6 weeks of vestibular rehabilitation, the incidence of gain abnormality was 22.9% (11/48), the incidence of phase abnormality was 31.3% (15/48), and the incidence of asymmetry was 12.5% (6/48).The horizontal gain at frequency of 2.0-3.9 Hz showed statistically significant difference compared with before vestibular rehabilitation (<0.05), and the horizontal gain at frequency of 4.3-5.9 Hz showed that there was no significant difference (>0.05); the horizontal phase at 5.9 Hz showed that the difference was statistically significant (=0.043), and there was no significant difference before and after rehabilitation treatment at 2.0-5.5 Hz (>0.05); the vertical gain at 4.3 Hz showed the difference was statistically significant (=0.020), and the remaining frequency showed no significant difference (>0.05); No frequency of asymmetry and vertical phase showed the difference before and after rehabilitation was statistically significant (>0.05). VAT can be used to monitor the change trend of multiple frequency bands before and after vestibular rehabilitation in UVH, in order to provide reference for the formulation of personalized rehabilitation strategies.
探讨单侧前庭功能减退（UVH）患者前庭康复治疗前后前庭自旋转试验（VAT）的动态变化。进行一项回顾性研究，纳入2019年1月至2021年1月在华中科技大学同济医学院附属协和医院耳鼻咽喉科诊断为UVH并接受前庭康复治疗的48例患者。其中，男性21例，女性27例，平均年龄46.9岁，包括梅尼埃病25例、突发性聋伴眩晕13例、前庭神经炎10例。病程为5天至10年。收集患者的人口学特征、详细病例资料及常规检查。收集前庭康复前后不同频率下VAT的水平增益/相位、垂直增益/相位及不对称性。对康复前后2.0 - 5.9 Hz测量值与标准值之差的绝对值进行统计学分析。前庭康复前，增益异常发生率为62.5%（30/48），相位异常发生率为56.3%（27/48），不对称性发生率为16.7%（8/48）。前庭康复4 - 6周后，增益异常发生率为22.9%（11/48），相位异常发生率为31.3%（15/48），不对称性发生率为12.5%（6/48）。2.0 - 3.9 Hz频率下的水平增益与前庭康复前相比差异有统计学意义（<0.05），4.3 - 5.9 Hz频率下的水平增益差异无统计学意义（>0.05）；5.9 Hz频率下的水平相位差异有统计学意义（=0.043），2.0 - 5.5 Hz频率下康复治疗前后差异无统计学意义（>0.05）；4.3 Hz频率下的垂直增益差异有统计学意义（=0.020），其余频率差异无统计学意义（>0.05）；不对称性及垂直相位各频率康复前后差异均无统计学意义（>0.05）。VAT可用于监测UVH患者前庭康复前后多个频段的变化趋势，为制定个性化康复策略提供参考。
