It is well known that rotational chair testing offers a reliable, repeatable and tolerable stimulus to the inner ear to investigate the function of the vestibular system, specifically the vestibulo-o…

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…
What is the Dix-Hallpike test? The Dix-Hallpike test, also referred to as the Dix-Hallpike maneuver, is a diagnostic maneuver used to identify benign paroxysmal positional vertigo (BPPV). The Dix-Hal…
Epley Maneuver for posterior canal BPPV Begin with the patient’s head turned 45 degrees toward the affected side. Bring to a supine position with the head turned toward the affected side and hanging…
What is the supine roll test? The supine roll test is a diagnostic maneuver used to identify horizontal canal benign paroxysmal positional vertigo (HC-BPPV). During the supine roll test, the patient…
In this course, adapted from an eWorkshop, Dr Kamran Barin, Ph.D., will present a series of vestibular assessment cases studies in order to explore how to select and develop the most appropriate asse…

For many years, we have used the term ‘vestibular function testing’ with the implication that we are testing the entire vestibular system. In fact, most of our tests, such as the caloric test, vHIT…
What is positional nystagmus testing? Positional nystagmus testing determines whether a change of position of the patient’s vestibular systems in space provokes nystagmus. Some nystagmus is only evid…
