UNLABELLED
Benign Positional Paroxysmal Vertigo (BPPV) is one of the most common vestibular diseases and the active head rotation test one of the most modern methods of vestibular function assessment.
AIM
this study aims to verify if the active head rotation test may reveal signs of horizontal and/or vertical vestibulo-ocular reflex dysfunction in vertigo patients suspected for BPPV.
STUDY DESIGN
retrospective series study.
MATERIALS AND METHOD
Neurotological evaluation including computerized electronystagmography and active head rotation on the horizontal and vertical axes were conducted in 100 patients suspected for BPPV patients.
RESULTS
Isolated or associated abnormalities of the horizontal and/or vertical vestibulo-ocular reflex gain, phase and symmetry were indicative of vestibular involvement and found in 77.0% of the BPPV patients.
CONCLUSION
the active head rotation test revealed horizontal and/or vertical vestibulo-ocular reflex dysfunctions in a relevant number of BPPV patients.
未加标签
良性阵发性位置性眩晕（BPPV）是最常见的前庭疾病之一，主动头旋转试验是评估前庭功能的最现代方法之一。
目的
本研究旨在验证主动头旋转试验是否可揭示疑似 BPPV 的眩晕患者的水平和/或垂直前庭眼反射功能障碍的迹象。
研究设计
回顾性系列研究。
材料和方法
对 100 例疑似 BPPV 患者进行神经耳科学评估，包括计算机眼震电图和主动头在水平和垂直轴上的旋转。
结果
水平和/或垂直前庭眼反射增益、相位和对称性的孤立或相关异常表明存在前庭受累，在 77.0%的 BPPV 患者中发现。
结论
主动头旋转试验在相当数量的 BPPV 患者中揭示了水平和/或垂直前庭眼反射功能障碍。
