INTRODUCTION AND OBJECTIVES The caloric test is the gold standard for the loss of vestibular function diagnosis. The Video Head Impulse Test (vHIT) assesses the same reflex by using a video- assisted examination of the impulsive maneuver. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at...

OBJECTIVE The objective of this study was to establish which factor leads to a higher vestibulo-ocular reflex (VOR) gain: the timing of the movement or the direction of the movement. For this purpose, healthy volunteers were examined under three conditions: (1) when they were informed about the timing of the head movement; (2) when they were informed about the direction of the head movement; an...

Video head impulse test (v-HIT) is a quick and non-invasive to evaluate vestibular function compared the caloric test. The latter is, however, needed decide on optimal side for cochlear implantation avoid inducing bilateral are flexia. This study evaluates effectiveness of using v-HIT select implant (CI) candidates who require subsequent testing before implantation.

The performance characteristics of football helmets are currently evaluated by simulating head impacts in the laboratory using a linear drop test method. To encourage development of helmets designed to protect against concussion, the National Operating Committee for Standards in Athletic Equipment recently proposed a new headgear testing methodology with the goal of more closely simulating in v...

ABSTRACT Background: The video head impulse test (vHIT) is a recent technique for functional evaluation of semicircular canals (SSCs). vHIT examines eye movements at high frequencies stimulation and provides an objective assessment the functioning high-frequency domain vestibular system. Objective: To describe results from performed using two systems. Methods: All subjects were evaluated throug...

Objectives: This study was performed to evaluate characteristics and their prognostic value of video-head impulse test (vHIT) in sudden sensorineural hearing loss (SSNHL) with vertigo.Methods: Of the 612 patients a diagnosis SSNHL from 2010 2018, 110 (18.0%) vertigo 39 (6.4%) vHIT results were recruited. The evaluated for pure-tone average (at initial, 1-month, 6-month visit), presence re-fixat...
