ACTIVE CEPHALIC AUTO-ROTATION IN PATIENTS WITH DIZZINESS/ VERTIGO

Abstract
Active cephalic auto-rotation is a rapid, easy, painless and confort test, that can be done in children and evaluate the vestibulo-ocular reflex in the physiologic frequencies of head, used in the every day life (from one to four hertz). A group of 5292 patients with dizziness, vertigo, hearing loss and tinnitus underwent the horizontal active cephalic auto-rotation test with fixed target, as a part of otoneurological evaluation to verify the alterations that showed up. Ages rate from three to 93 years with average of 49,6 years, being 75% females and 25% males. The vertigo complaint was reported by 70% patients and dizziness by 30%. The frequency answering rate to cephalic auto-rotation test ranged from 1,5 to 7,5Hz with average of 3,5Hz. The most frequent alterations were those having to do with the gain (increase – reduction) isolated or associated to alterations of phase and symmetry.

Key words
Cephalic auto-rotation test, dizziness, vertigo
