Abstract
METHODS: This is an observational cohort study of pregnant women at an urban academic medical center from November 2017 to June 2018. Women with short cervical length (CL) ,2.5 cm were compared to women with normal CL ($3 cm). Primary outcome was pattern of bioelectrical activity in both groups. Secondary outcomes were characteristics of identified signals. All subjects had a singleton pregnancy between 16w0d and 22w6d. Up to 4 proprietary uEMG electrode pads (PreTel, Inc., Chattanooga, TN), 4 commercially available ECG pads, a ground electrode, and a tocometer were placed on the lower abdomen. EMG recordings were obtained for 60 minutes using a Porti amplifier (TMSi, Oldenzaal, Netherlands) and analyzed between 0.15 and 1.2 Hz.
