在10名健康男性志愿者上，分别用皮肤电极(胃电)和腔内压力记录法对消化间期肌电活动和机械活动进行同步研究。本研究的目的是(1)描述健康受试者消化间期移行复合体(IMC)不同时相的胃电特征；(2)确定这些特征在多大程度上可用于识别IMC的不同时相。对胃电进行直观分析和运行频谱分析。结果表明，人类胃电的频率在运动时不如在运动静止时稳定，特别是在第三时相，但比犬的稳定得多。在从运动静止到第二阶段运动活动的转换过程中，观察到胃频率有轻微但持续的下降。胃电频率的功率随运动活动的增加而增加，但III时相除外。只有少数IMCs才能识别出III时相特有的频率和功率行为。一般来说，鉴于目前的技术水平，胃电图不能用来准确地识别IMC的不同阶段。
Interdigestive myoelectric activity and mechanical activity were studied simultaneously by means of cutaneous electrodes (electrogastrography) and intraluminal pressure recording, respectively, in 10 healthy male volunteers. The aims of the present study were (1) to describe the characteristics of the electrogastrogram during the different phases of the interdigestive migrating complex (IMC) in healthy subjects and (2) to determine to what extent these characteristics can be used to identify the different phases of the IMC. The electrogastrograms were analyzed visually and by running-spectrum analysis. It was concluded that in humans the gastric frequency present in the electrogastrogram appears to be less stable during motor activity than during motor quiescence, in particular during phase III, but far more stable than its canine counterpart. A small but consistent drop in gastric frequency was observed in the changover from motor quiescence to phase II motor activity. The power of the gastric frequency increasesd with increasing motor activity, except during phase III. A characteristic frequency and power behaviour during phase III could only be recognized in a minority of the IMCs. In general, electrogastrography cannot, given the present state of the art, be used to precisely identify the different phases of the IMC.
