Ultrasound-guided pelvic floor training to help birth in first-time pregnant women

Official title: The Effect of Ultrasound Visual Feedback on Birth Outcomes in Nulliparous Women With Levator Ani Muscle Co-activation at Term Pregnancy: A Randomized Controlled Trial

Run by IRCCS Azienda Ospedaliero-Universitaria di Bologna · NCT07675642 · Data updated 2026-11-12

This study tests if real-time ultrasound feedback on pelvic floor muscles during labor preparation helps shorten the second stage of labor in first-time pregnant women with specific pelvic floor muscle activation.

Is this trial a fit for you?

Likely a good fit

Nulliparous women at term pregnancy (37 weeks or later) with singleton gestation who show levator ani muscle co-activation and are candidates for vaginal delivery.

Probably not a fit

Women without levator ani co-activation, those not pursuing vaginal delivery, or those with exclusion criteria may not benefit from this intervention.

What this trial studies

This single-center, randomized controlled trial compares ultrasound-based visual feedback training of the pelvic floor to standard care in nulliparous women at term who show levator ani muscle co-activation. Participants receive a transperineal ultrasound session with real-time visualization and coaching on pushing technique. The primary goal is to see whether this approach can reduce the duration of the second stage of labor. The study is interventional and non-profit, enrolling during routine antenatal visits at term. Outcomes include labor timing and safety in the context of vaginal delivery.

Why it matters

Potential benefit: If successful, the approach could shorten the second stage of labor and improve delivery efficiency for first-time mothers with levator ani co-activation.

How similar studies have gone: Prior early trials using ultrasound visualization for pelvic floor training have shown potential benefits in labor dynamics, making this approach plausible but still exploratory for this specific population.
