The Video Head Impulse Test
In 1988, we introduced impulsive testing of semicircular canal (SCC) function measured with scleral search coils and showed that it could accurately and reliably detect impaired function even of a single lateral canal. Later we showed that it was also possible to test individual vertical canal function in peripheral and also in central vestibular disorders and proposed a physiological mechanism...

CONCLUSION Additional research is needed to validate the importance of the video head impulse tests (vHIT), but it provides an important contribution to the evaluation of anterior and posterior semicircular canal disorders. OBJECTIVES To share observations of the vHIT test in clinical neurotology and to discuss the significance of the study findings. METHODS This study comprised 200 patient...
متن کاملApplication of the video head impulse test to detect vertical semicircular canal dysfunction.
OBJECTIVE The video head impulse test (vHIT) is a useful clinical tool to detect semicircular canal dysfunction. However, so far, vHIT has been limited to measurement of the function of the horizontal semicircular canals. The goal of this study was to determine if vHIT can detect vertical semicircular canal dysfunction. STUDY DESIGN Horizontal and vertical eye movements were recorded in respo...
متن کاملThe Video Head Impulse Test (vHIT) Detects Vertical Semicircular Canal Dysfunction
BACKGROUND The video head impulse test (vHIT) is a useful clinical tool to detect semicircular canal dysfunction. However vHIT has hitherto been limited to measurement of horizontal canals, while scleral search coils have been the only accepted method to measure head impulses in vertical canals. The goal of this study was to determine whether vHIT can detect vertical semicircular canal dysfunct...
متن کاملThe Video Head Impulse Test (vHIT) of Semicircular Canal Function – Age-Dependent Normative Values of VOR Gain in Healthy Subjects
BACKGROUND/HYPOTHESIS The video Head Impulse Test (vHIT) is now widely used to test the function of each of the six semicircular canals individually by measuring the eye rotation response to an abrupt head rotation in the plane of the canal. The main measure of canal adequacy is the ratio of the eye movement response to the head movement stimulus, i.e., the gain of the vestibulo-ocular reflex (...
