Alcohol and the vestibulo-ocular reflex (VOR)

I was drawn to this paper initially for slightly unscientific reasons but in fact it proved a worthwhile read. It describes the effect of alcohol consumption on the VOR of eight healthy subjects as measured using video head impulse testing...

Impaired vestibulo-ocular reflex (VOR) gain correlates with hearing loss in vestibular schwannoma

The lack of correlation between the size of vestibular schwannoma (VS) and degree of hearing loss and vestibular function tests is well known. In this retrospective study, the focus was on the correlation between VOR gain of semicircular canal function,...

The video head impulse test: an aid to the diagnosis of spinocerebellar ataxias

Spinocerebellar and Friedreich ataxias (SCA and FA) by their nature present in neuro-otology clinics. The diagnosis is ultimately genetic but the authors investigated the characteristics of the VOR using the video head impulse test (vHIT) in order to distinguish between...

aVOR – An Educational Tool

As anyone who has tried to learn the anatomy and physiology of the vestibular system can attest, understanding and visualising the structures and their functions can be quite challenging. Thankfully, there is now a free app called aVOR (iOS, iTunes...

Clinical utility and practical interpretation of the video head impulse test

The head impulse test (HIT) is an essential bedside test to detect peripheral vestibular deficits. The video head impulse test (vHIT) is a new tool quantifying the HIT. In this article Maria Heuberger and colleagues point out the clinical utility...

The applicability and reliability of SHIMP, a new vestibular test, in adolescents

The video head impulse (now called the head impulse paradigm – HIMP) is now a routine test battery in neuro-otological practice. Few will be familiar with the new suppression head impulse paradigm (SHIMP) test. The key difference is that, in...

International classification of bilateral vestibulopathy (BVP)

In the past few years the Bárány Society have been standardising the diagnostic criteria for various vestibular disorders – International Classification of Vestibular Disorders (ICVD). Diagnosis of BVP relies on history, bedside clinical assessment and objective vestibular tests. The authors...

A twitch in time with a flicker of knowledge

The middle ear muscles can be seen as one of the ear’s safety mechanisms, and the interplay between eyes and ears has been established; think vestibular ocular reflex (VOR) or semi-circular canal dehiscence (SCCD). But can this protective mechanism be...

Update on the development of an implantable vestibular prosthesis

Cochlear implants have revolutionised the management of profound hearing loss. Might vestibular implants be the future for the treatment of bilateral vestibular failure? James Johnston and Neil Donnelly explore. The vestibular system is highly complex, integrating visual, labyrinthine and proprioceptive...

Rotational Vestibular Assessment

Although Rotational Vestibular Assessment is a textbook aimed primarily at audiologists, all specialists involved in vestibular work, including medics, physiotherapists and scientists will find something of interest here. The writing style adopted, combined with the numerous illustrations, all help to...

Vestibular rehabilitation therapy: diagnosis based strategies

In his second article on this topic (see here for the first article), Richard E Gans explains how to use vestibular rehabilitation therapy to treat vestibular patients, and demonstrates why this method of diagnosis based strategies has proved so successful....

Three state-of-the-art Orion rotary chairs

As part of their release of the new VisualEyes™ software, Interacoustics has added new rotary chairs to their extensive list of balance equipment.
