【摘要】：目的:对急性单侧外周前庭功能损失的患者使用机动化的头脉冲试验量化前庭功能的恢复,并把这些结果与其他体征和症状相比较。方法:使用机动化头脉冲旋转仪记录30例突发单侧前庭功能障碍的患者平均在发生后3d(前期)的潜在的水平前庭眼反射(VOR),20例患者平均3个月后(后期)继续测量。计算VOR增益和不对称(s趚±s)。结果:从前期的患侧增益0.49±0.21到后期的0.79±0.23(P=0.0000)有高度显著改善。各自的不对称从(32±18)%到(12±14)%(P=0.0002)也有高度显著改善。至少80%的患者增益或不对称恢复。后期的高症状评分与低增益(P=0.043)和高不对称(P=0.018)有相关性。结论:用机动化的头脉冲旋转仪来测量减少的水平VOR增益,突发单侧前庭功能损失后至少部分恢复。除了眼震的传统评价,头脉冲试验的反应为前庭损失的严重程度和恢复提供了有价值的信息。
[Abstract]:Objective: to quantify the recovery of vestibular function in patients with acute unilateral peripheral vestibular dysfunction using motorized head pulse test. The results were compared with other signs and symptoms. Methods: 30 patients with sudden unilateral vestibular dysfunction were recorded with a motorized head pulse rotator at an average of 3 days after onset of the latent horizontal vestibular eye reflex. The VOR gain and asymmetry gain were calculated from 0.49 卤0.21 to 0.79 卤0.23P0. 00000.There was a significant improvement from 0. 49 卤0. 21 to 0. 79 卤0. 23 P0. 0000. Their asymmetries ranged from 32 卤18% to 12 卤14 P0. 0002). Significant improvement. At least 80% patients had gain or asymmetric recovery. High symptom scores were correlated with low gain P0. 043) and high asymmetry P0. 018). Conclusion: reduced horizontal VOR gain was measured with a motorized head pulse rotator. In addition to the traditional evaluation of nystagmus, the response of head pulse test provides valuable information on the severity and recovery of vestibular loss.
