What is the gaze test? The gaze test measures the patient’s ability to maintain a steady gaze on an object at various angles without the eye generating extraneous movements (i.e. square wave jerks or…
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 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…
Le test calorique est le test de référence pour la fonction du canal semi-circulaire latéral. Elle consiste à introduire de l'air ou de l'eau chaude et froide dans les oreilles d'un patient et à mesu…
Le test optocinétique utilise un système similaire au système de poursuite fluide et en fait le système de poursuite fluide est impliqué dans ce test. La différence est que le stimulus lors des tests…
