Sensory organization test (SOT) is used to evaluate postural instability. We wanted to characterize the SOT findings in patients with acute vestibular neuritis (VN).
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.
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).
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.
感觉组织测试（SOT）用于评估姿势不稳。我们旨在描述急性前庭神经炎（VN）患者的SOT检查结果特征。
纳入87例VN患者。进行了冷热试验和SOT，并将结果与头晕残障量表（DHI）的结果进行比较。异常的SOT模式分为：严重、视觉前庭、前庭、不一致或正常模式。结果还通过感觉分析（本体感觉、视觉、前庭和视觉偏好）和综合评分进行分析。
61例患者（70%）在条件5和/或6（前庭模式）下显示异常结果，其中一半（61例中的30例，49%）在条件5和6之外还显示了其他异常结果。在模式分析中，前庭模式（条件5和6异常）是最常见的模式（36%），视觉前庭模式（条件4、5和6异常）是第二常见的模式（24%）。在感觉分析中，59例患者（68%）观察到前庭功能障碍，37例（43%）观察到视觉功能障碍，17例（20%）观察到视觉偏好，5例（6%）观察到本体感觉功能障碍。SOT的综合评分与DHI评分显著相关，尽管未观察到DHI与冷热试验结果之间存在相关性（p<0.05）。
VN可对姿势不稳产生不利影响，存在更严重的模式以及经典的前庭模式，这表明异常的前庭输入可在所有SOT条件下影响姿势稳定性，并且急性VN患者的主观症状与姿势不稳而非半规管功能障碍更密切相关。
