title: [Up-beating nystagmus in craniocervical trauma: a videooculographic assessment of 569 cases].
abstract: Between February 1998 and July 1999 a total of 569 patients with vertigo subsequent to cranial and/or cervical trauma underwent otovestibular study: tonal audiometry, auditory brain stem evoked potentials, clinical and instrumental otovestibulogical examination (bithermal test, rotatory test, visuooculomotory test and static stabilometry). Oculomotory analysis was performed using the Ulmer videooculographic system. The purpose of this work was to analyze both the quality and quantity of the vestibulometric and semiotic data obtained. Emphasis is placed on the significant incidence of "up-beating" nystagmus in the various categories of patients, supported by a statistical study. Then a hypothesis for the etiopathogenesis of such nystagmus is proposed, based on an alteration in the cervical proprioceptive information and on an abnormal otolitic input pattern. Moreover, the importance of the videonystagmographic system is underlined as it permits the standardized, objective analysis essential for both clinical and forensic purposes.
