The bedside head impulse, first described nearly 20 years ago, is the single most useful clinical test of the human vestibulo-ocular reflex (VOR). The video head impulse test (vHIT), its laboratory counterpart, now enables the objective assessment of the VOR. We examine how the vHIT can be utilized in three common clinical scenarios: the acute vestibular syndrome, recurrent spontaneous vertigo, and chronic imbalance. Combined with vestibular evoked myogenic potentials (VEMPs), vHIT enables assessment of all five vestibular end-organs by a clinician within the clinic itself.
床边摇头试验最早于近20年前被描述，是人体前庭眼反射（VOR）最有用的单项临床检查。其实验室对应检查——视频头脉冲试验（vHIT），现在能够对VOR进行客观评估。我们探讨了vHIT如何应用于三种常见临床情况：急性前庭综合征、复发性自发性眩晕和慢性平衡失调。vHIT与前庭诱发肌源性电位（VEMP）相结合，使临床医生能够在诊所内对所有五个前庭终器进行评估。
