The Effect of Different Head Movement Paradigms on Vestibulo-Ocular Reflex Gain and Saccadic Eye Responses in the Suppression Head Impulse Test in Healthy Adult Volunteers

Frontiers in Neurology, 2021
Objective: This study aimed to identify differences in vestibulo-ocular reflex gain (VOR gain) and saccadic response in the suppression head impulse paradigm (SHIMP) between predictable and less predictable head movements, in a group of healthy subjects.

Binocular video head impulse test: Normative data study

Frontiers in Neurology, 2023
IntroductionThe video head impulse test (vHIT) evaluates the vestibulo-ocular reflex (VOR). It’s usually recorded from only one eye. Newer vHIT devices allow a binocular quantification of the VOR.Purpose (Aim)To investigate the advantages of ...

Diagnostic assessment of patients with Meniere's disease through caloric testing and the video-head-impulse test

Brazilian Journal of Otorhinolaryngology, 2021
Introduction: Meniere's disease is a labyrinth disease that usually presents with episodes of spontaneous vertigo associated with sensorineural hearing loss, tinnitus and ipsi- and unilateral aural fullness in most cases. Vestibular function tests, video-

The Role of Neck Input in Producing Corrective Saccades in the Head Impulse Test

Frontiers in Neurology, 2022
BackgroundThe head impulse test is a valuable clinical test that can help identify peripheral vestibular dysfunction by observing corrective saccades that return the eyes to the target of interest.

What does the video head impulse test tell us about post-caloric vestibular recruitment?

Brazilian Journal of Otorhinolaryngology, 2023
Objective: The vestibular recruitment observed in caloric testing is a new tool in the study of the vestibulo-ocular reflex. This study aimed to determine the sensitivity and specificity of the video head impulse test to detect post-caloric vestibular ...

Comparison of EOG and VOG obtained eye movements during horizontal head impulse testing

Frontiers in Neurology, 2022
IntroductionVideo head impulse testing is frequently used to evaluate the vestibular function. During this test, eye movement responses are recorded with video-oculography (VOG).

Short-Latency Covert Saccades - The Explanation for Good Dynamic Visual Performance After Unilateral Vestibular Loss?

Frontiers in Neurology, 2021
Background: Functional head impulse test (fHIT) tests the ability of the vestibulo-ocular reflex (VOR) to allow visual perception during head movements. Our previous study showed that active head movements to the side with a vestibular lesion generated a
