飞行员前庭剌激眼震电图的观察

为探讨前庭刺激方式、强度、运动病症状与ＥＮＧ变化的关系，对６２名飞行人员分成Ⅰ和Ⅱ两组（各３１名），用科氏加速度及角加、减速度的不同刺激强度诱发眼震（ＥＮＧ）进行分析。结果：科里澳利加速度刺激诱发眼震慢相波幅、快相波幅、慢相速度和快相速度值低。而角加、减速度刺激诱发这四项参数值高；柯氏刺激强度大，运动病症状重，刺激强度小症状轻；症状与旋转眼震的慢相波幅、慢相速度、快相速度和频率无关，与快相波幅相关。

Observation of Electronystagmogram in Pilots under Vestibular Stimulation.

The relationship between electronystagmogram(ENG) and intensity of veistibular stimulation was observed in 62 pilots.31 pilots received low intensity vestibular stimulation and the other 31 pilots received higher intensity vestibular stimulation.Electronystagmogram were recorded and analysed.The results showed that there was no relationship between the ENG parameters and stimulation intensity,but both slow phase and fast phase velocities and amplitudes were lower under Coriolis acceleration stimulus,while all of them were higher under angular acceleration and angular stimulations.It was also found that the fast phase amplitude of ENG was related to motion sickness symptoms of the subjects.
