计算机化动态姿势描记术（EquiTestTM设备）的感觉组织测试（SOT）是用于研究个体如何使用平衡系统感觉输入（前庭、视觉、本体感觉/躯体感觉）来保持安静站立的有价值的工具;然而，其作为识别外周前庭系统功能障碍的筛选工具是有限的。之前的研究表明，在标准SOT电池的部分中添加水平摇头可以改善外周前庭系统不对称性的识别;然而，注意到这些方法中的缺陷。本研究的目的是评估改良摇头SOT（HS-SOT）方案识别外周前庭系统病变的敏感性和特异性。最终分析纳入了15例主诉不稳定、眩晕和/或头晕的患者，伴或不伴热量性单侧无力（UW），以及15例年龄匹配的健康对照。15例患者中有10例显示热量UW >= 25%。参与者在头部静止的情况下完成SOT的标准条件2和5，并且在四个水平摇头任务期间（即，HS-SOT 2 -60度/秒、HS-SOT 2 -120度/秒、HS-SOT 5 -15度/秒和HS-SOT 5 -60度/秒）。每组的平均平衡评分随着条件难度的增加而降低（SOT 2、HS-SOT 2 -60度/秒、HS-SOT 2 -120度/秒、SOT 5、HS-SOT 5 -15度/秒和HS-SOT 5 -60度/秒）;正如预期，与患者（斜率= -11.69）相比，对照组（斜率= -6.59）的下降幅度较小。HS-SOT 5 -15度/秒条件对于识别外周前庭不对称性是上级的（AUC = 0.90，灵敏度= 70%，特异性= 100%），与热量UW%的相关性最强（r（s）=-0.743，p = 0.000006）：HS-SOT 5 -15度/秒似乎是外周前庭不对称性的有希望的筛选测量。(C)2016爱思唯尔B.

The Sensory Organization Test (SOT) of Computerized Dynamic Posturography (EquiTest (TM) equipment) is a valuable tool for investigating how an individual uses balance system sensory input (vestibular, vision, proprioception/somatosensory) to maintain quiet stance; however, it is limited as a screening tool for identifying peripheral vestibular system dysfunction. Previous research has shown that adding horizontal head-shake to portions of the standard SOT battery improved the identification of peripheral vestibular system asymmetry; however, flaws in the methods were noted. The objective of this work was to evaluate the sensitivity and specificity of the modified head-shake SOT (HS-SOT) protocol for identification of peripheral vestibular system lesion. Fifteen patients with chief complaint of instability, vertigo, and/or lightheadedness, with and without a caloric unilateral weakness (UW) and fifteen age matched healthy controls were included in the final analysis. Ten of the 15 patients demonstrated a caloric UW >= 25%. Participants completed standard conditions 2 and 5 of SOT with head still and during four horizontal head-shaking tasks (i.e., HS-SOT2-60 degrees/s, HS-SOT2-120 degrees/s, HS-SOT5-15 degrees/s, and HS-SOT5-60 degrees/s). Average equilibrium scores decreased as condition difficulty increased (SOT2, HS-SOT2-60 degrees/s, HS-SOT2-120 degrees/s, SOT 5, HS-SOT5-15 degrees/s, and HS-SOT5-60 degrees/s) for each group; as expected, a lower decline was noted for controls (slope = -6.59) compared to patients (slope = -11.69). The HS-SOT5-15 degrees/s condition was superior for identifying peripheral vestibular asymmetry (AUC = 0.90 sensitivity = 70%, specificity = 100%), with the strongest correlation to caloric UW% (r(s) = -0.743, p = 0.000006): HS-SOT5-15 degrees/s appears to be a promising screening measure for peripheral vestibular asymmetry.
