normative 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 Caloric Test and the Video Head-Impulse Test in Patients with Vertigo
MATERIALS and METHODS: This is a prospective work in 123 patients with different types of vestibular disease seen because of dizziness in which both procedures were performed the same day. First, the spontaneous nystagmus and head-shake nystagmus were measured. The video head-impulse test was carried out, and finally, the caloric test was performed with water at two different temperatures. Both...
متن کاملThe 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...
متن کاملThe video head impulse test.
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 کاملRelationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.
INTRODUCTION AND OBJECTIVES The caloric test is the gold standard for the loss of vestibular function diagnosis. The Video Head Impulse Test (vHIT) assesses the same reflex by using a video- assisted examination of the impulsive maneuver. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at...
