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(珚x±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。
