Book Summary: Dizziness comes in many forms in each age group – some specific to an age group (e.g. benign paroxysmal vertigo of childhood) while others span the age spectrum (e.g., migraine-associated vertigo). This content organizes evaluation and management of the dizzy patient by age to bring a fresh perspective to seeing these often difficult ...

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

Stability of the aVOR to Repeat Head Impulse Testing
Otology & Neurotology, 2016The angular vestibulo-ocular reflex (aVOR) is known to be influenced by factors such as arousal and cognition during traditional vestibular function testing. However, the inherent variability of the aVOR to head impulse testing has not been explicitly examined. The purpose of this study was to determine the variability of the aVOR to active and passive

Head-Impulse and Caloric Tests in Patients With Dizziness
Otology & Neurotology, 2003To test the performance of the head-impulse and caloric tests in terms of sensitivity, specificity, and predictive efficiency.This was an open and prospective study conducted at a tertiary care center in which 265 patients were subjected to the head-impulse test and caloric test on the same day.

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 and seasickness susceptibility
Experimental Brain ResearchSeasickness can have a devastating effect on a crewmember's well-being. In the literature, there is a controversy about whether car sickness could be diagnosed by vestibular evaluation tests, specifically by Video Head impulse test (vHIT) a semi-circular canal (SCC) function test.

The Vestibulo-ocular Reflex and Head Impulse Testing
2019The major role of the vestibulo-ocular reflex (VOR) is to stabilize the eyes for clear vision during movement in daily life. Periodic head movements during normal life activities move the head at fundamental frequencies of 2–4 Hz, with harmonics extending above these frequencies.
