title: [Variations of EGG in subjects under vestibular stimulation].
abstract: 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.
