The Video Head Impulse Test (vHIT) – English

In four chapters this module covers the physiological principles of the head impulse test and how to perform the test in practice with video goggles. The course is device-independent; wherever controls or cleaning agents become specific, they are marked as examples taken from Merlin.

After the module you will be able to describe how a semicircular canal senses a head rotation and how the vestibulo-ocular reflex keeps the visual field stable; you will know the three test planes lateral, LARP and RALP; you will be able to prepare the test procedure and deliver the head impulses correctly; you will recognize artifacts and insufficient measurement quality; and you will know the contraindications, the hygiene requirements and the boundary between taking a measurement and making a medical diagnosis.
