This paper discusses the mechanism of weighted averaging and in what circumstances it improves otoacoustic emission (OAE) measurements. It details investigations of OAE measurements on a wide range o…

This article introduces the dynamic visual acuity (DVA) test and its role in assessing vestibular compensation. Table of contents Visual acuity Pathophysiology of dynamic visual acuity Clinical appli…
The calibration procedure for lateral canal calibrations has not changed and is described in the manual. You can begin testing without calibrating by selecting a test and starting the impulses. In th…
There are big differences between what people call virtual reality (VR) for persons with balance and vestibular disorders. Use of a head-mounted device, a CAVE (large scene that is not moveable from…
When we refer to the admittance of the outer and middle ear system (i.e. its ability to convey sound energy) then we can consider the spring elements that compress and expand (like a spring) includin…
One application for diagnostic otoacoustic emissions is in the use of ototoxicity monitoring. Ototoxic agents include antibiotics (particularly aminoglycosides), loop diuretics such as furosemide, ch…
It can often be very difficult to diagnose posterior canal BPPV when relying on two-dimensional graphs that only show horizontal and vertical eye traces. It can also be difficult for the examiner to…
It is relatively simple to track horizontal and vertical eye movements using videonystagmography (VNG) because they can be directly deduced from the position of the pupil. However, torsional movement…

The eye movements that are mediated by the semicircular canals through the vestibulo-ocular reflex (VOR) are well-known and used in many clinical tests of vestibular function. These reflexive eye mov…
What is the Quality Assurance feature? The Quality Assurance feature is designed to monitor the software during use and provide live feedback to the clinician to ensure that the expected workflow is…
