Intraobserver reliability of posturography in patients with vestibular neuritis.

The aim of the study was to establish the intraobserver reliability of a posturographic method in patients (n = 34) with vestibular neuritis. Intraclass correlation coefficients (relative reliability) for all parameters and test positions (ALL(mean)) ranged from 0.71 (95% CI: 0.41-0.85) to 0.92 (95% CI: 0.84-0.96). Absolute reliability (coefficient of variation) ranged between 3.1% (95% CI: 2.60-8.67) and 42.3% (95% CI: 40.7-74.5). Reliability of single test positions is much lower. The posturographic system showed good relative and satisfactory absolute intraobserver reliability for ALL(mean).
