用胃电图(EGG)记录14例飞行员平静状态和视动刺激下(转鼓速度为60°/s)的胃电变化。次日开始每日进行重复视动刺激(转鼓速度为30°/s)10分钟,共进行7天,最后进行平静状态和视动刺激下(转鼓速度为60°/s)的EGG复查,观察重复刺激对飞行员视诱发性运动病的影响。结果显示:重复视动刺激后,飞行员平静状态的胃电频率和振幅及视动中的频率均无明显变化(P>0.05),而视动刺激中的胃电振幅明显降低,与重复视动刺激前相比差异具有显著性(P<0.05),且受试者运动病症状的发生率也明显降低(P<0.05)。认为:重复视动刺激能降低飞行员在视动刺激下的胃电振幅,并能减轻视诱发性运动病的症状。
Electrogastrogram (EGG) was used to record the electrogastric changes of 14 pilots under tranquilization and optokinetic stimulation (drum speed of 60 ° / s). The following day, daily repeat photodynamic stimulation (drum speed of 30 ° / s) for 10 minutes for a total of 7 days, the final state of calm and visual stimulation (drum speed of 60 ° / s) EGG review , To observe the impact of repeated stimulation of pilot-induced motion sickness. The results showed that there was no significant change in the frequency and amplitude of gastrocnemius and the frequency of visual acuity (P> 0.05), while the amplitude of gastric electrical activity in visual acuity stimulation was significantly decreased after repetitive visual acumen stimulation. Compared with repeated visual acuity The difference between before and after stimulation was significant (P <0.05), and the incidence of motion sickness symptoms was significantly decreased (P <0.05). It is considered that repeated optokinetic stimulation can reduce the amplitude of the electrogastrogram of pilots under optokinetic stimulation and relieve the symptoms of astigmatism.
