MOBY: Birth mobility for first-time mothers during labor
Official title: The MOBY Study - Efficacy of Birth Mobility: Randomized Clinical Trial Investigating the Efficacy of Birth Mobility on Birth Outcomes in Primiparous Women With and Without a Birth Mobility System.
Run by Vibwife AG · NCT07052331 · Data updated 2026-11-12
This trial tests whether using a birth mobility system during labor helps first-time mothers have fewer secondary cesarean sections and better delivery outcomes.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are term (≥37+0 weeks) first-time mothers with a low-risk singleton cephalic pregnancy who are ≥18 years old, speak German or English, can provide informed consent, and plan to deliver at Kantonsspital Baden.
✕Probably not a fit
Women with a scheduled cesarean, contraindications to vaginal birth, multiple pregnancy or breech presentation, estimated fetal weight below the 10th or above the 90th percentile, significant fetal abnormalities, preeclampsia/HELLP, relevant intrapartum bleeding, or pre-existing conditions that seriously limit mobility are unlikely to benefit.

What this trial studies
The randomized trial at Kantonsspital Baden enrolls 714 primiparous, low-risk women at term who are randomly assigned to standard care with a conventional birthing bed or to standard care plus access to a CE-marked birth mobility system with a short instructional video. Position and movement during labor are recorded passively by a non-intrusive monitoring setup, while the clinical team continues routine care and position recommendations. The primary outcome is the rate of secondary (intrapartum) cesarean sections, and secondary outcomes include labor progression, medication use, neonatal adaptation, and user satisfaction captured via short postnatal questionnaires for participants and midwives. Participation involves routine clinical data collection during birth and a brief questionnaire after delivery.
Why it matters
Potential benefit: If successful, the intervention could reduce emergency cesarean deliveries and improve labor progression and satisfaction for first-time mothers.
How similar studies have gone: Prior research indicates that upright positions and maternal mobility can shorten labor and reduce cesarean risk, but randomized evidence specifically testing a CE-marked birth mobility system is limited.
