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 کاملEvaluation of Bilateral Vestibular Dysfunction in Iranian Adults and Elderlies by Electronystagmography and Video Head Impulse Test
Introduction: Vestibular abnormalities are common problems in the whole world, which can lead to bilateral vestibular dysfunction (BVD). That results in symptoms, such as vertigo, unsteadiness, falling, oscillopsia, and lower quality of life. The Objective of this study was to determine BVD in adults and elderlies with vertigo and unsteadiness. Materials and Methods: This study was conducted ...
متن کاملnormative vestibulo-ocular reflex data in yaw and pitch axes using the video head-impulse test
background and aim: the video head-impulse test (vhit) measures the vestibulo-ocular reflex (vor) driven by each semicircular canal, following high-acceleration head rotations. the main measurable response is the ratio of eye movement velocity to the angular head velocity, which reflects canal function. although normative data is available for vor gain, most studies only report horizontal vo...
متن کاملThe video head impulse test: diagnostic accuracy in peripheral vestibulopathy.
BACKGROUND The head impulse test (HIT) is a useful bedside test to identify peripheral vestibular deficits. However, such a deficit of the vestibulo-ocular reflex (VOR) may not be diagnosed because corrective saccades cannot always be detected by simple observation. The scleral search coil technique is the gold standard for HIT measurements, but it is not practical for routine testing or for ac...
