Motion sickness is a disease caused by vehicles with symptoms of digestive system, as well as pale and cold sweat. It is often observed in parabolic flight which produces microgravity and hypergravity. Recently, Electrogastrography (ECG) has been developed to record gastric electroactivity percutaneously. In order to examine whether ECG was available as an index of nausia and vomitting in motion sickness, ECG was measured during parabolic flight in this study. As a result, from scoring of motion sickness according to the diagnosis table, four in eight subjects were diagnosed as motion sickness. Although there was individual difference in amplitude and frequency of ECG, motion sickness occurred in subjects who had large amplitude before vomiting, or high frequency as nausea became worse. It was also observed that trajectory of ECG turned to the opposite direction when gravity shifted from 0 to 2 G. Therefore, ECG might be useful as an objective index of motion sickness, however, further studies with large population would be necessary in order to remove individual differences.
