Abstract

Objective: Sensory organization test (SOT) is used to evaluate postural instability. We wanted to characterize the SOT findings in patients with acute vestibular neuritis (VN). Methods: Eighty-seven patients with VN were enrolled. The bithermal caloric and SOT were performed, and the results were compared with those from the dizziness handicap inventory (DHI). Abnormal SOT patterns were classified: severe, visual vestibular, vestibular, inconsistent, or normal patterns. The results were also analyzed by sensory analysis (somatosensory, visual, vestibular, and visual preference) and composite scores. Results: Sixty-one patients (70%) showed abnormal findings for conditions 5 and/or 6 (vestibular pattern), and half (30 of 61, 49%) of them showed additional abnormal results in more than conditions 5 and 6. In pattern analysis, the vestibular pattern (abnormal in conditions 5 and 6) was the most common pattern (36%), and the visual vestibular pattern (abnormal in conditions 4, 5, and 6) was the second most common (24%). In sensory analysis, vestibular dysfunction was observed in 59 patients (68%), visual dysfunction in 37 (43%), visual preference in 17 (20%), and somatosensory dysfunction in 5 (6%). Composite scores of SOT showed a significant correlation with the DHI scores, though no correlation was observed between DHI and caloric results (p < 0.05). Conclusion: VN can adversely influence on postural instability, with more severe patterns as well as classical vestibular patterns, indicating that abnormal vestibular inputs can influence postural stability in all SOT conditions and subjective symptom in patients with acute VN is more closely associated with the postural instability rather than canal dysfunction.
