秋千诱发运动病过程中胃电图的观察

Observation on Electrogastrogram Changes during Parallel Swing Stimulation.

为探讨体表胃电图和运动病恶心综合症的关系，对３２名被试者平行秋千诱发运动病的胃电图进行功率谱分析。２０名被试者胃电间期主频由实验前每分钟３次（２．４０～３．７０ｃｐｍ）上移至胃动过速（３．７０～１０．００ｃｐｍ）；间期主频（ＰＤＦ）、胃动过速段功率值的百分比和主频变异系数（ＤＦＩＣ）有非常显著性增加（Ｐ＜０．０１）；秋千停摆后即刻被试者运动病症状明显。结果表明：胃电图可以用来检测运动病恶心综合症。

In order to study the relationship between cutaneous electrogastrogram (EGG) and nausea syndrome of the motion sickness, power spectrum analysis is used to analyze EGG recorded during motion sickness evoked by the parallel swing in 32 healthy men. 20 subjects showed a shift of Period Dominant Frequency(PDF) of EGG from Three CPM (2.40～3.70cpm) to Tachygastria (3.70～10.00cpm).PDF,the percentage of power of Tachygastria wave and Dominant Frequency Instability Coefficient significantly increased (P<0.01).The incidences of nausea syndrome was obvious at the moment after swing. The result showed that EGG may be used for testing nausea symptoms of motion sickness.
