Spatial-temporal analysis of uterine smooth muscle activity recorded during pregnancy.
We performed recording of the magnetic fields (Magnetomyography - MMG) corresponding to the electrical activity of the uterine smooth muscle with a device called SARA, (SQuid Array for Reproductive Assessment). Past studies suggest that the uterus passes through a preparatory process before entering labor and resulting in delivery of the fetus. But the electrophysiological mechanism of this process is not completely understood. We propose four parameters that will allow us quantify the characteristics of the uterine MMG signal obtained from 151 sensors spread over the pregnant abdomen. In summary, we believe that spatial-temporal analysis mapping of uterine activity will help us better understand the process of labor.
