目前评估分娩过程的方法，如分娩力测定或宫内压力导管、胎儿纤维连接蛋白、宫颈长度测量和数字宫颈检查，具有几个主要缺点。它们只能间接测量分娩的开始，不能检测到真正分娩的细胞变化特征。因此，它们对足月或早产的预测价值很差。子宫收缩是子宫肌层内电活动的结果。子宫肌电图（EMG）的测量已被证明可以像目前使用的方法一样准确地检测收缩。此外，细胞兴奋性的变化和耦合所需的有效收缩，导致交付反映在几个EMG参数的变化。使用子宫肌电图可以帮助确定病人在真正的劳动比任何其他方法目前在临床上使用。
Current methodologies to assess the process of labor, such as tocodynamometry or intrauterine pressure catheters, fetal fibronectin, cervical length measurement and digital cervical examination, have several major drawbacks. They only measure the onset of labor indirectly and do not detect cellular changes characteristic of true labor. Consequently, their predictive values for term or preterm delivery are poor. Uterine contractions are a result of the electrical activity within the myometrium. Measurement of uterine electromyography (EMG) has been shown to detect contractions as accurately as the currently used methods. In addition, changes in cell excitability and coupling required for effective contractions that lead to delivery are reflected in changes of several EMG parameters. Use of uterine EMG can help to identify patients in true labor better than any other method presently employed in the clinic.
