我们研究了13例听神经瘤切除后单侧外周前庭病变的患者。术后VOR的时间常数为6.4+/-2.6秒（正常为18.5+/-7.7秒）。术后OKAN的时间常数为7.2+/-1.8秒（正常值为11.3+/-3.2秒）。术后OKAN的平均初始速度为9.7+/-2.4度/秒（正常值为11.7+/-5.9度/秒）。这些数据表明，单侧外周前庭损失与通道输入的速度存储的完全损失有关，但视觉输入的速度存储仅部分损失。这些结果可以用现有的速度存储机制的数学模型来解释。
We studied 13 patients with unilateral peripheral vestibular lesions following removal of acoustic neurinomas. The time constant of the VOR after surgery was 6.4+/-2.6 seconds (normal is 18.5+/-7.7 seconds). The time constant of OKAN after surgery was 7.2+/-1.8 seconds (normal is 11.3+/-3.2 seconds). The mean initial velocity of OKAN after surgery was 9.7+/-2.4 deg/second (normal is 11.7+/-5.9 deg/second). These data suggest that unilateral peripheral vestibular loss is associated with a complete loss of velocity storage for canal input but only a partial loss of velocity storage for visual input. These results can be accounted for by current mathematical models of the velocity storage mechanism.
