In addition, between 30 and 50% of subjects diagnosed with preterm contractions go on to deliver at term 12. Particularly, previous studies found that TOCO cannot identify patients who are in labor, at term or preterm 10, 11. Previous studies have shown that these methods have limited ability to distinguish between women who will respond to induction/oxytocin augmentation and deliver vaginally and those that require cesarean 9. In current clinical practice, overall signals generated by uterine contractions are measured qualitatively via tocodynamometry (TOCO) or quantitatively via an invasive intrauterine pressure catheter (IUPC) 8. Accurately assessing and interpreting uterine contractions is essential for diagnosing both labor dysfunction and preterm labor. Preterm birth occurs in 10.6% of women globally 4, with increased infant risks of mortality before 5 years of age 5, adverse long-term neurodevelopmental outcomes 6, and an increased economic burden on the family and society 7. Cesarean deliveries increase the risks of maternal morbidity and neonatal respiratory morbidity compared to vaginal delivery 3. Approximately 29% of women deliver via cesarean 1, the majority of which are performed for labor arrest 2. Two essential challenges in obstetrics worldwide are arrest of labor and preterm birth. We thus show that the human EMMI system can provide detailed 3D images and quantification of uterine contractions as well as novel insights into the role of human uterine maturation during labor progression. Quantitative indices, including the uterine activation curve, are developed and defined to characterize uterine surface contraction patterns. We demonstrate the successful integration of the human EMMI system during subjects’ clinical visits to generate noninvasively the uterine surface electrical potential maps, electrograms, and activation sequence through an inverse solution using up to 192 electrodes distributed around the abdomen surface. Herein we describe the development and application of a human EMMI system to image and evaluate 3D uterine electrical activation patterns at high spatial and temporal resolution during human term labor.
