The diagnosis of central vestibular disorders based on the complementary examination of the vestibulospinal reflex

Objectives

Stance and gait unsteadiness along with vertigo contribute to a central vestibular disorder. For objective analysis ultrasound-computer-craniocorpography (US-COMP-CCG) can be used. Aim of the study was to characterize the unsteadiness in central vestibular disorders and discuss the possible diagnostic usage of US-COMP-CCG.

Methods and results

Hundred-and-ninety patients (70 male and 120 female, mean age ± SD, 58.94 ± 15.27) suffering from central vestibular disorder and 230 healthy control patients (78 male and 152 female, mean age ± SD, 50.94 ± 15.27) were enrolled. Stance and gait analysis was according to vestibulospinal tests of US-COMPCCG. IBM SPSS V24 software was used for statistical analysis. Mann-WhitneyU test and Chi-square test were used, along with sensitivity and specificity categorization. The significance level was p < 0.05. According to schematic and statistical analysis instability and postural sway were increased in the vertigo population and statistically significant difference was shown. Upon categorical analysis significant correlation was detected [standing test: longitudinal sway (p < 0.00001), lateral sway (p < 0.00001), forehead covering area parameters (p = 0.0001); stepping test: longitudinal deviation (p = 0.05), lateral sway (p = 0.011) parameters].

Conclusions

Clinicians should consider that postural instability is prominently present in this population and might be of a diagnostic importance.
