DIAGNOSTIC EVALUATION OF COMPLEX SUPPRESSION OF CALORICA NYSTAGUM IN VESTIBULAR DISORDERS
Abstract
The article presents the results of a cumulative nystagmus suppression test in caloric samples. Based on a comparison of the severity of nystagmus (in units of the speed of the slow component) in the areas focused and not focused by the gaze, the cumulative suppression index (CSI) was calculated. Complete suppression of caloric nystagmus was the most common response in at least one of the PD trials (24 observations). A serious (above 0.50) FBI value with caloric nystagmus was observed in rare cases (3 people). The inclusion of gaze concentration when performing all 4 PD tests can serve as an additional test method in the comparative diagnosis of vestibular disorders. The results of the summation test should be compared with data obtained from other vestibulometric tests.
