The Effects of Relaxation on Guided Imagery of the pregnant women and the fetuses

本研究的目的是探讨引导意象法对孕妇和胎儿的放松效果。对46例妊娠36 ~ 41周的无并发症单胎妊娠妇女的平均心率、综合肌电图（EMG）和胎儿运动计数进行了测量。与卧床休息相比，70%的女性在检查时平均心率和额部综合肌电图倾向于降低，60%的女性胎儿运动倾向于增加2。对83例妊娠35 ~ 41周的无并发症单胎妊娠妇女进行心理生理分析。83名受试者被随机分为37名女性自体训练（AT）组和46名女性引导图像（GI）组。休息20分钟后，分别用上述两种方法测量额叶肌电图和松弛指数，持续10分钟。综合肌电图显示GI组低于AT组，且在6分钟后较卧床休息明显降低，GI组的松弛量表明显高于AT组。一名妊娠25周的无并发症单胎妊娠妇女接受了GI方法的训练，每周两次，直到孩子出生。在妊娠过程中，胎儿心理意象的松弛指数和量表呈上升趋势。结果表明，妊娠期胃肠法比体外循环法更有效，且可能对胎儿反应有影响。

The purpose of this study was to investigate the relaxation effects of the guided imagery methods for the pregnant women and fetuses.1. The mean heart rate, the integrated the electromyography (EMG), and the fetal movement counting in 46 women with uncomplicated singleton pregnancies at 36 to 41 weeks' gestation were measured.Comparing with bed rest, the mean heart rate and the intergrated EMG of the frontalis during the examination were intended lower at the women of 70%, and the fetal movement incresed at the women of 60%.2. The difference between the guided imagery and the autogene training in 83 women with uncomplicated singleton pregnancies at 35 to 41 weeks' gestation was analized psychophysiologically. The 83 subjects ware randamely divided into the 37 women autogene training (AT) group and the 46 women guided imagery (GI) group.After 20 minutes bad rest, EMG of the frontalis and relaxation index were measured in the above 2 methods for 10 minutes. The integrated EMG indicated that the GI group were lower than the AT group, significantly at after 6 minutes comparing with bed rest, and the relaxation scale of GI group were higher than that of AT group significantly.3. One woman with uncomplicated singleton pregnancies at 25 weeks' gestation was trained by GI methods twice a week till the child birth. The relaxation index and the scale of mental imagery on fetus incresed along the pregnant process.It was indicated that GI methods for the pregnacies were more effective than AT methods, and might be have an influence the fetal reactions.
