Peanut ball position may reduce C-Sections in labor trial
NCT ID NCT05881629
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study tests if lying on your side with a peanut ball between your legs during labor can help babies turn to the right position and reduce the need for C-sections or forceps delivery. 200 pregnant women with babies facing the wrong way will be randomly assigned to this position or any position they choose. Researchers will track delivery outcomes and how women feel about their labor experience.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Maternal position change to side-lying lateral with peanut ball
- What this could lead to
- If it works, this simple position change could help more women deliver vaginally and reduce the need for C-sections.
- What could go wrong
- This is a small, early-stage trial. The position change may not help all babies turn, and results may not apply to everyone.
