To examine the correlation of video head impulse test, functional head impulse test and Dizziness Handicap Inventory results in patients with chronic unilateral vestibular loss, and to compare the results with healthy controls.
Forty-eight patients diagnosed with chronic unilateral vestibular loss and 35 healthy individuals, aged 18-65 years, were included. The video head impulse test, functional head impulse test and Dizziness Handicap Inventory were administered.
A significant positive correlation was found between functional head impulse test and video head impulse test results for the study group in all semicircular canals ( < 0.05). There was no significant correlation between Dizziness Handicap Inventory, functional head impulse test and video head impulse test results ( > 0.05). The functional head impulse test and video head impulse test results of the control group were significantly higher than those of the study group in all semicircular canals planes ( < 0.05).
In chronic unilateral vestibular loss patients, with high head accelerations, the functional head impulse test indicates deterioration in vestibulo-ocular reflex functionality. It would be beneficial to include the video head impulse test and functional head impulse test in clinical practice as complementary tests in vestibulo-ocular reflex evaluation.
研究慢性单侧前庭损失患者视频头脉冲试验、功能性头脉冲试验和眩晕残障量表结果的相关性，并与健康对照组进行比较。
纳入 48 例慢性单侧前庭损失患者和 35 名年龄在 18-65 岁之间的健康个体。对所有研究对象进行视频头脉冲试验、功能性头脉冲试验和眩晕残障量表评估。
研究组所有半规管的功能性头脉冲试验和视频头脉冲试验结果均呈显著正相关（<0.05）。眩晕残障量表、功能性头脉冲试验和视频头脉冲试验结果之间无显著相关性（>0.05）。对照组所有半规管平面的功能性头脉冲试验和视频头脉冲试验结果均显著高于研究组（<0.05）。
在慢性单侧前庭损失患者中，随着头部加速度的增加，功能性头脉冲试验提示前庭眼反射功能恶化。在临床实践中，将视频头脉冲试验和功能性头脉冲试验作为前庭眼反射评估的补充试验是有益的。
