Refining the Video Head Impulse Test Diagnostic Accuracy: A Case-Control Study.

Audiol Neurootol, 2023
Introduction: Current clinical practice considers the vestibulo-ocular reflex (VOR) gain as registered by the video head impulse test (vHIT) as the primary measure for semicircular canal function, while the role of the re-fixation saccades (RSs) is still

A Clinical Infrared Video-Oculoscopy Suppression Head Impulse (IR-cSHIMP) Test [PDF]

Audiology Research
Background: We propose a Suppression Head IMPulse (SHIMP) test method that provides for equipment only through the use of InfraRed Video-OculoScopy (IR-VOS) and allows horizontal and vertical semicircular canal function evaluation in bedside mode.

Video head impulse test for the assessment of vestibular function in patients with idiopathic sudden sensorineural hearing loss without vertigo. [PDF]

J Laryngol Otol, 2023
Objective Idiopathic sudden sensorineural hearing loss may be accompanied by dizziness without true vertigo. This study used the video head impulse test to evaluate vestibular function in idiopathic sudden sensorineural hearing loss patients who ...

The video Head Impulse Test (vHIT) detects vertical semicircular canal dysfunction. [PDF]

PLoS ONE, 2013
BACKGROUND: The video head impulse test (vHIT) is a useful clinical tool to detect semicircular canal dysfunction. However vHIT has hitherto been limited to measurement of horizontal canals, while scleral search coils have been the only accepted method ...

Aging increases compensatory saccade amplitude in the video head impulse test [PDF]

Frontiers in Neurology, 2016
Objective: Rotational vestibular function declines with age resulting in saccades as a compensatory mechanism to improve impaired gaze stability. Small reductions in rotational vestibulo-ocular reflex (VOR) gain that would be considered clinically ...

Methods for Detecting the Patient’s Pupils’ Coordinates and Head Rotation Angle for the Video Head Impulse Test (vHIT), Applicable for the Diagnosis of Vestibular Neuritis and Pre-Stroke Conditions

De Computis
In the contemporary era, dizziness is a prevalent ailment among patients. It can be caused by either vestibular neuritis or a stroke. Given the lack of diagnostic utility of instrumental methods in acute isolated vertigo, the differentiation of ...

Video head impulse test (vHIT) unravels the hidden pathology in chronic vestibular deficit

The Egyptian Journal of Otolaryngology
Background The caloric test is persistently altered in chronic peripheral vestibular hypofunction (PVH). So, we cannot depend on it to measure the degree of compensation in chronic vestibulopathy patients who are still complaining.

Video head impulse test (vHIT) in migraine dizziness

Journal of Otology, 2018
Migraine is an extremely prevalent primary headache disorder that frequently associates parallel symptoms such as dizziness, tinnitus and hearing loss. Our aim is to investigate differences in video head impulse (vHIT) results with patients suffering from vestibular migraine (VM) and healthy people, taking into consideration mean values of vestibule ...
