Prototipo de video frenzel-video head impulse test de bajo coste

open access: yesCiencia y Salud, 2019
Antecedentes: desde la introducción de las gafas de Frenzel se han desarrollados múltiples sistemas que permiten no permiten no solo observar el nistagmo, sino documentarlo y valorar su evolución y respuesta al tratamiento; pero el costo pero el costo de

Vestibular-evoked myogenic potentials and video head impulse test in cochlear otosclerosis

open access: yesThe Egyptian Journal of Otolaryngology, 2023
Background Otosclerosis is one of the most common causes of hearing loss in adults with clinical onset between 20 and 40 years of age. Vestibular symptoms may be the most agonizing and primary symptom in cases with otosclerosis, so the assessment of ...

The Video Head Impulse Test in a Case of Suspected Bilateral Loss of Vestibular Function

open access: yesInternational Archives of Otorhinolaryngology, 2016
Introduction A patient who had no symptoms suggestive of bilateral loss of vestibular function presented no responses in rotational and caloric tests. Objectives To demonstrate the importance of the video head impulse test in neuro-otologic ...

Covert anti-compensatory quick eye movements during head impulses. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: Catch-up saccades during passive head movements, which compensate for a deficient vestibulo-ocular reflex (VOR), are a well-known phenomenon.

Aging increases compensatory saccade amplitude in the video head impulse test

open access: yesFrontiers 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 ...

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

open access: yesAudiology 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.

The video head impulse test (vHIT) of semicircular canal function – age dependent normative values of VOR gain in healthy subjects

open access: yesFrontiers in Neurology, 2015
Background/Hypothesis. The video Head Impulse Test (vHIT) is now widely used to test the function of each of the six semicircular canals individually by measuring the eye rotation response to an abrupt head rotation in the plane of the canal.

The Functional Head Impulse Test to Assess Oscillopsia in Bilateral Vestibulopathy

open access: yesFrontiers in Neurology, 2019
Introduction: Bilateral vestibulopathy (BV) is a chronic condition in which vestibular function is severely impaired or absent on both ears. Oscillopsia is one of the main symptoms of BV. Oscillopsia can be quantified objectively by functional vestibular

VIDEO HEAD IMPULSE TEST – EYE ECG

open access: yesLiječnički vjesnik, 2017
In the diagnosis of acute vestibular syndrome (AVS) the key part is a quick and reliable differentiation between peripheral and central etiologies. Video head impulse test (vHIT) is a new method that is based on the examination of rotational vestibulo-ocular reflex. vHIT has demonstrated high specificity for peripheral vestibular damage.

Horizontal eye position affects measured vertical VOR gain on the video Head Impulse Test

open access: yesFrontiers in Neurology, 2015
Background/Hypothesis. With the video Head Impulse Test (vHIT), the vertical VOR gain is defined as (vertical eye velocity/vertical head velocity), but compensatory eye movements to vertical canal stimulation usually have a torsional component.
