Description: The purpose of this instructional course is to show clinicians how to perform the video head impulse test (vHIT) properly. In order to do this, it is of paramount importance to learn all of the following: 1) theory behind the head impulse test, 2) how to perform the vHIT test, 3) how to avoid artifacts and noise, 4) how to read vHIT test results, and 5) how to interpret vHIT test results. All recommendations will be based upon best clinical practice reflecting current scientific evidence.
Outcome Objectives: Following this instructional course, attendees will know how to perform the vHIT optimally. This includes an understanding of the theory behind the vHIT test as well as an understanding of the correct and optimal vHIT test procedures (test set-up and practical use). Prerequisites for post-vHIT test interpretation skills include: 1) quality of test, 2) identification of noise and artefacts, 3) when to use (or not use) manual data selection, 4) how to read the test results, and 5) how to interpret the test results (pathological test parameter requirements).
Background: During the last decade, use of the vHIT has become more and more common and widespread for evaluation of vestibular function. The test is generally widely accepted amongst patients and, the test itself, is often considered fairly easy and fast to carry out. However, sufficient knowledge on how to perform the vHIT correctly is not so commonly encountered. If carried out correctly, the vHIT has a very high negative predictive value and, if pathological, discerns information on the Vestibulo-Ocular-Reflex (VOR) with all three paired semicircular canals. If not carried out correctly, patients may wrongly be diagnosed with a vestibular hypofunction or wrongly be acquitted of having a vestibular disease.
The vHIT test is NOT a “plug and play” examination. Very important to show clinicians how to perform the test properly and how to avoid or minimize artifact triggers
I received my Medical degree from Aarhus University, Denmark in 2004 and I was certified as an ENT Specialist in 2012. Since 2014 I have been the Head of the Audiovestibular Department at Aalborg University Hospital, Denmark as well as an Associate Professor of Otolaryngology at Department of Clinical Medicine, Aalborg University, Denmark. I have been a Board member of the Danish Vestibular Society since 2017, President from 2020-2023 and Vice President from 2017-2019 and from 2024 and onwards. Primary areas of interest include inner ear diseases, audiology, neurotology, and Bone Anchored Hearing Aids. Work areas include an oto-surgery, neurotology, medical audiology, and research. The primary focus of my research is clinical research of inner ear diseases within the audiological- and vestibular subspecialties. Current research areas primarily include diagnostics and treatment of Benign Paroxysmal Positional Vertigo (BPPV) with Mechanical Rotation Chairs, video Head Impulse Testing, Wide Band Tympanometry in diagnostics of inner ear diseases, telemedicine in audiology and Implants for Bone Anchored Hearing Systems.
