Recently with the introduction of video head impulse test (vHIT), it can be easily performed quantitative and objective measurement of vestibulo-ocular reflex (VOR). vHIT has been used as a clinical vestibular function test that can individually evaluate the function of each semicircular canal. Loss of VOR gain and corrective catch-up saccades that occur during the vHIT usually indicate peripheral vestibular hypofunction, whereas in acute vestibular syndrome, normal vHIT should prompt a search for a central lesion. In this study, we will examine the principle of vHIT and its interpretation, and explain its clinical application in peripheral and central vestibulopathy. In addition, we will compare the caloric test and the differences, and review the most recently introduced suppression head impulse paradigm test.

Abstract PDF

Objective: Cervical vestibular evoked myogenic potential (cVEMP) is thought to be assessing the function of the saccule and inferior vestibular nerve. Therefore, cVEMP indirectly reflects the function of the posterior semicircular canal. Recently, the video head impulse test (vHIT) is considered as useful clinical tool to detect each semicircular canal dysfunction. Goal of this study was to evaluate and compare the results of cVEMP with posterior canal plane of vHIT (p-vHIT).
Methods
Retrospectively, we compared the results of cVEMP with p-vHIT in 43 patients who visited with dizziness. We analyzed the inter-test agreement of cVEMP with p-vHIT.
Results
Positive asymmetry of cVEMP was present in 37.2% (16/43), and no responses of both ears were identified in 16.3% (7/43). In p-vHIT analysis, unilateral positive was 27.9% (12/43), bilateral positive was 11.6% (5/43) and negative in both sides was 60.5% (26/43). The inter-test agreement between cVEMP and p-vHIT was 75.8% (25/33) as we considered even in lesion side. And, Fleiss’s kappa value showed a fair to good agreement (kappa value=0.559). In bilateral no response group (7 patients) in cVEMP, variable additional information could be obtained using p-vHIT.
Conclusion
cVEMP and p-vHIT showed relatively lower inter-test agreement than expected. But, p-vHIT could be easily performed, and give additional information for differential diagnosis.

Abstract PDF: Positional vertigo and nystagmus without focal neurological symptoms and signs are characteristic features of benign paroxysmal positional vertigo (BPPV). And the apogeotropic positional nystagmus can be diagnosed as cupulolithiasis of the horizontal semicircular canal. However, cerebellar lesion involving especially nodulus could be initially presented as positional vertigo like a BPPV without other neurologic signs. In most of the patients with cerebellar involvement, initial presentation shows dysarthria, ataxia, headache, nausea, vomiting and unsteadiness. But in some central lesions, positional nystagmus might be observed in head roll test as if BPPV was presented. It is very important for clinicians of dizziness care unit to differentiate central positional vertigo (CPV) from BPPV. But it is difficult to diagnose CPV at initial visit by history and physical exam only. Therefore, we introduce two cases with cerebellar infarction and hemorrhage initially presenting isolated positional vertigo mimicking BPPV.
