The role of the smooth cervical muscle has not yet been sufficiently explored. For that reason cervical EMG was measured during induced labour of several primiparas and multiparas. Three spiral electrodes were placed on the cervix in order to measure the EMG in the longitudinal and circular direction referred to the cervical axis. A quantitative analysis of changes in the amplitude and frequency of the EMG signals was performed by means of the spectral method. It was found that the EMG measured from the two leads differed in unripe cervices in the latent phase of labour. The differences are illustrated by two cases. Some possible explanations for the different activity are discussed.
宫颈平滑肌的作用尚未得到充分研究。因此,在几名初产妇和经产妇引产过程中测量了宫颈肌电图。为了测量沿宫颈轴纵向和环向的肌电图,在宫颈上放置了三个螺旋电极。通过频谱方法对肌电信号的幅度和频率变化进行了定量分析。发现在分娩潜伏期,从未成熟宫颈测量的两条导联的肌电图存在差异。通过两个病例说明了这些差异。讨论了不同活动的一些可能解释。
