title: Vestibular function in HIV patients: preliminary report.
abstract: Main purpose of this study was to evaluate vestibular function, focusing attention on percentage of peripheral damage in 30 HIV positive patients (23 male, 7 female), age range 26-68 years, belonging to Categories A-C of CDC classification of infection, underwent electronystagmography with bithermic stimulation according to Freyss (125 cc of water at 30 degrees C and 44 degrees C in 30 sec). The angular velocity of slow phase was considered as the main value of labirinthine functionality. Peripheral vestibular damage has been found in 35.7% of Class A patients; a similar percentage of peripheral signs was found in Classes B and C, where, on the contrary, increased central vestibular signs were observed. In order to evaluate equilibrium in these patients, a Dynamic Gait Index (DGI) test was performed. Scores were >21 points in 85.7% of Class A patients and decreased in Classes B and C.
