方法:受试者为7名健康志愿者(男5名、女2名),让其坐在直径为76cm、高91.5cm、内壁交替画着白、黑色竖条纹的圆筒内,使圆筒以60°/S的速度向右旋转,诱发视觉性晕动病。同时记录圆筒旋转前、旋转时、旋转后15min的胃电图,并用自觉症状记分法(SSMS)评价旋转负荷时伴随症状的变化。胃电图用FFT分析,描记光率谱,计算记录范围内正常与异常波所占的比例,比较与SSMS变化的相关性。
Methods: The subjects were seven healthy volunteers (5 males and 2 females). They were allowed to sit in a cylinder with a diameter of 76 cm and a height of 91.5 cm. The inner wall was alternately painted with white and black vertical stripes, so that the cylinder Rotate to the right at 60 ° / S to induce visual motion sickness. At the same time, the gastrogram of the cylinder before rotation, rotation, 15min after rotation was recorded and the change of symptoms accompanied with rotation load was evaluated by SSMS. The electrogastrogram was analyzed by FFT, the light spectrum was traced, and the proportion of normal and abnormal waves in the recording area was calculated, and the correlation with changes of SSMS was compared.
