Objective. To investigate the patterns of electrogastrogram [correction of electrogastrogragm] (EGG) before, during and after vestibular stimulation. Method. 25 subjects were stimulated by Coriolis acceleration and 28 by Coriolis [correction of corolis] stimulation. Result. Dysrythmia of EGG and increase of tachygastria were recorded in all subjects during the stimulation. The period dominant frequency (PDF) of EGG shifted from 2.40-3.70 cpm to 3.70-10.00 cpm during Coriolis stimulus in subjects with nausea. Conclusion. It suggests that PDF could be a parameter in reflecting the level of motion sickness.
目的。研究前庭刺激前后及刺激过程中胃电图（EGG）的变化模式。方法。25名受试者接受科里奥利加速度刺激，28名受试者接受科里奥利刺激。结果。所有受试者在刺激过程中均记录到胃电图节律紊乱及快速胃动过速增加。恶心受试者在科里奥利刺激期间，胃电图的周期主导频率（PDF）从2.40 - 3.70次/分钟移至3.70 - 10.00次/分钟。结论。这表明PDF可能是反映晕动病程度的一个参数。
