We sought to determine whether placental implantation site affects electromyographic (EMG) recordings of uterine activity in labor. We performed a prospective study of women randomly selected on admission to labor ward. There were acceptable recordings in 36 women, 18 in both the posterior and anterior placenta groups. There were 12 unacceptable recordings. This was mainly due to poor electrode contact. There was no difference in amplitude, frequency, activity integral, total activity integral, or power density in either group. EMG can be used to quantify uterine activity irrespective of placental position.
我们试图确定胎盘着床位置是否会影响分娩时的子宫活动肌电图（EMG）记录。我们对随机选择在劳动病房入院的女性进行了一项前瞻性研究。有 36 名女性的记录可以接受，其中 18 名女性的胎盘位于前后壁。有 12 个记录不可接受。这主要是由于电极接触不良。两组的振幅、频率、活动积分、总活动积分或功率密度均无差异。EMG 可用于量化子宫活动，而与胎盘位置无关。
