Official title
Multichannel Surface Electromyography in Labor and Parturition
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will examine how the uterus, abdominal wall, pelvic floor and brain interact during labor and parturition. It will uses electromyography (EMG) to compare the characteristics of the uterus, abdominal wall and perineum in subjects with and without various pregnancy characteristics. EMG will help established burst frequency and characteristics of the uterus compared to other parts of the body during labor and delivery. Other parts of the body may include abdominal surfaces (for uterine, abdominal, maternal EMG and fetal heart rate monitoring), perineal surface (for perineal muscles monitoring) and the maternal scalp (brain monitoring). EEG measures the electrical activity of the brain. The activity is recorded using wire electrodes attached to the scalp or mounted on a cap placed on the head. E MG measures electrical activity from muscles. It uses wire electrodes placed on the skin over the muscles. Pregnant adult volunteers and patients who present to the investigator's institution may be eligible for this study. Participants will lay or sit in a semi-reclining chair with sticker electrodes placed on the body surface area of interest. Muscle and/or brain activity will be measured with EEG and EMG recordings.
