The bedside head impulse, first described nearly 20 years ago, is the single most useful clinical test of the human vestibulo-ocular reflex (VOR). The video head impulse test (vHIT), its laboratory counterpart, now enables the objective assessment of the VOR. We examine how the vHIT can be utilized in three common clinical scenarios: the acute vestibular syndrome, recurrent spontaneous vertigo, and chronic imbalance. Combined with vestibular evoked myogenic potentials (VEMPs), vHIT enables assessment of all five vestibular end-organs by a clinician within the clinic itself.

The video-Head-Impulse-Test (vHIT) is widely used to evaluate vestibular function. Nevertheless, there is no consensus on the necessary or ideal number of impulses performed for robust VOR gains. Ther...
The vestibulo-ocular reflex (VOR) is the only system that maintains stable vision during rapid head rotations. The VOR gain (eye/head velocity) can be trained to increase using a vestibular-visual mis...
The diagnosis of the various peripheral and central vestibular disorders is mainly based on the patient history (time course, type of symptoms, modulating factors, and accompanying symptoms) and a sys...
The purpose of this research study is to test whether a Computerized Rotational Head Impulse Test-Vertical (crHIT-vertical) is able to reliably evaluate the vertical semicircular canals in...
The purpose of the current study is to determine if pre-exposure through video modeling will enhance testing compliance in a population of children who are receiving a diagnostic evaluatio...
This study will measure the effects of soft surgical techniques on vestibular function and quality of life in patients pre- and post-cochlear implant (CI) surgery. Additionally, the invest...
The purpose of the investigator's study is to assess the effect of a standardized prenatal testing educational video on the use of prenatal genetic testing and decision-making.
This is a randomized prospective pilot study assessing the safety and feasibility of two yoga interventions in head and neck cancer patients undergoing primary or adjuvant radiation with o...

Used with articles which include video files or clips, or for articles which are entirely video.
Endoscopic surgical procedures performed with visualization via video transmission. When real-time video is combined interactively with prior CT scans or MRI images, this is called image-guided surgery (see SURGERY, COMPUTER-ASSISTED).
A form of interactive entertainment in which the player controls electronically generated images that appear on a video display screen. This includes video games played in the home on special machines or home computers, and those played in arcades. (McGraw Hill Encyclopedia of Science & Technology, 7th ed, v19, p223)
