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.

Effects of pupil size in video head-impulse tests
Journal of Neurology, 2023The results of video head impulse tests (video-HITs) may be confounded by data artifacts of various origins, including pupil size and eyelid obstruction of the pupil. This study aimed to determine the effect of these factors on the results of video-HITs. We simulated ptosis by adopting pharmacological dilatation of the pupil in 21 healthy participants (

Video head impulse test: a review of the literature
European Archives of Oto-Rhino-Laryngology, 2016Video head impulse test (vHIT) is a new testing which able to identify the overt and covert saccades and study the gain of vestibulo-ocular reflex (VOR) of each semicircular canal. The aim of this study is to review the clinical use of vHIT in patients with vestibular disorders in different diseases.

Video-head impulse test in superior canal dehiscence
Acta Oto-Laryngologica, 2021Superior Canal Dehiscence is classically diagnosed with typical abnormalities on Vestibular Evoked Myogenic Potentials (VEMPs) and Computed Tomography (CT) scans.This paper discusses the utility of the video Head Impulse Test (vHIT) in SCD.Data from 11 ears (8 patients) with SCD were retrospectively reviewed.

Head Impulse Testing Using Video‐oculography
Annals of the New York Academy of Sciences, 2009Head impulses are a routine clinical test of semicircular canal function. At the bedside, they are used to detect malfunctioning of the horizontal semicircular canals. So far, 3‐D‐search‐coil recording is required to reliably test anterior and posterior canal function and to determine the gain of the vestibulo‐ocular reflex (VOR). Search‐coil recording

Effect of aging and direction of impulse in video head impulse test
The Laryngoscope, 2017ObjectiveThe aim of this study was to identify the difference of gain value in the video head impulse test (vHIT) according to the age of the patient and the direction of the impulse.MethodAll participants were subjected to vHIT with horizontal semicircular canal (HSCC). vHIT with vertical canal (posterior and anterior semicircular canal [PSCC and ASCC]

Video Head Impulse Testing: From Bench to Bedside
Seminars in Neurology, 2020AbstractOver 30 years ago, the head impulse test (HIT) was measured with search coil recordings and it provided robust evidence for a new test of vestibular function that could detect impairment of a single semicircular canal, that is, the lateral canal.
