Ultrasound Muscle Imaging to Screen for Muscle Atrophy in Fetuses at Risk of AMC

Official title: Technical Feasibility Study of Ultrasound Muscle Imaging in Antenatal Ultrasound Screening of Congenital Multiple Arthrogryposis

Run by University Hospital, Grenoble · NCT06130592 · Data updated 2026-11-12

This study tests a new ultrasound method to look at muscle tissue during mid-pregnancy to see if it can help screen fetuses for muscle problems in pregnancies at risk for Arthrogryposis Multiplex Congenita.

Is this trial a fit for you?

Likely a good fit

Pregnant women between 21 and 24 weeks gestation, singleton pregnancies, evaluated at Lyon or Grenoble prenatal centers, with consent.

Probably not a fit

Pregnant women with multiple pregnancies, BMI over 30 in early pregnancy, or those not meeting other criteria may not benefit.

What this trial studies

This is an interventional study evaluating a specialized ultrasound technique to image fetal muscles during 21-24 weeks of gestation. The goal is to determine how feasible it is to perform four extremity muscle scans and specific tissue measurements in both low-risk and high-risk pregnancies suspected of AMC. The study focuses on pregnancy cohorts in Lyon and Grenoble, enrolling mono-zygotic pregnancies with regulatory consent. Primary endpoints center on the completion rate of the four extremity muscle sections and quantitative measurements between skin, fascia, and muscle layers. The approach addresses limitations of routine antenatal ultrasound for detecting AMC-related muscle atrophy.

Why it matters

Potential benefit: If successful, this technique could improve early detection of fetal muscle problems associated with AMC, informing planning and care.

How similar studies have gone: Prior approaches have shown limited sensitivity; this study tests a focused ultrasound method in AMC contexts and is relatively novel in this antenatal setting.
