Electromyography of the Pregnant Uterus in Humans and Sheep
نویسنده
چکیده
The aim of the investigation was to off-line compare parameters of uterine EMG signals recorded during pregnancy in humans and sheep. Uterine corpus EMG recording sessions were performed in humans and in sheep. Sixty-five women underwent uterine corpus EMG recording sessions using abdominal surface skin electrodes. Six sheep underwent multiple EMG recording sessions using implanted electrodes. RMS and MF values were calculated from EMG signals. According to the different origins of EMG signals, RMS values were normalised (nRMS). Differences between human and sheep EMG signals were assessed by comparing both parameters of EMG signals in different periods of pregnancy. The trends of nRMS values approaching EDD are similar for both groups; they show a similar average increase. MF values are different. In the human group they show a slight average decrease while in the sheep group they show a slight increase with approaching EDD. EMG activity in humans and sheep is similar in parameter nRMS and different in parameter MF.

Uterine Electromyography in Humans – Contractions, Labor, and Delivery
Today’s maternal/fetal monitoring lacks the capability to diagnose labor and predict delivery. The objective of this work was to demonstrate that uterine electromyography (EMG) is proven to be a viable alternative to current monitoring techniques. Uterine EMG was monitored noninvasively and trans-abdominally from pregnant patients using surface electrodes. Several aspects of the uterine EMG wer...

Background: Uterine factor infertility (UFI) refers to the refractory causes of female infertility stemming from the anatomical or physiological inability of a uterus to sustain gestation. Today, uterine factor infertility affects 3-5% of the population. Traditionally, although surrogacy and adoption have been the only viable options for females affected by this condition, the uterine transplan...

Reproductive abnormalities cause major losses of sheep production. Abattoir materials were used todetermine the extent of reproductive wastage. Reproductive tracts were collected from 524 ewes slaughtered at Urmia slaughter-house in Urmia, northwest of Iran, during a period of 12 months. Overall, 30.10% of the ewes examined were pregnant. A total of 149 (28.44%) tracts developed acquired reprod...
