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 کاملVestibulo-ocular reflex and the head impulse test.
The authors highlights the importance of the vestibulo-ocular reflex examination through the head impulse test as a diagnostic method for vestibular dysfunction as well as, and primarily, a bedside semiotic resource capable of differentiating between acute peripheral vestibulopathy and a cerebellar or brainstem infarction in emergency rooms.
متن کاملEthanol consumption impairs vestibulo-ocular reflex function measured by the video head impulse test and dynamic visual acuity.
Ethanol affects many parts of the nervous system, from the periphery to higher cognitive functions. Due to the established effects of ethanol on vestibular and oculomotor function, we wished to examine its effect on two new tests of the vestibulo-ocular reflex (VOR): the video head impulse test (vHIT) and dynamic visual acuity (DVA). We tested eight healthy subjects with no history of vestibula...

متن کاملAge dependent normal horizontal VOR gain of head impulse test as measured with video-oculography
BACKGROUND The head impulse test (HIT) is a recognised clinical sign of the high frequency vestibulo-ocular reflex (VOR), which can be quantified with video-oculography. This measures the VOR gain as the ratio of angular eye velocity to angular head velocity. Although normative data is available for VOR gain with video-oculography, most normal studies in general include small numbers of subject...
