The Claim

In nulliparous women during the second stage of labor, spontaneous pushing in the lateral position reduces maternal pain and fatigue severity compared to the Valsalva maneuver in the supine position, with mean pain scores of 7.80 vs. 9.05 and fatigue scores of 46.59 vs. 123.36.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

When women are giving birth for the first time and pushing during labor, pushing naturally while lying on their side may hurt less and feel less tiring than pushing hard while lying on their back.

  1. Study: Spontaneous Pushing in Lateral Position versus Valsalva Maneuver During Second Stage of Labor on Maternal and Fetal Outcomes: A Randomized Clinical Trial

    When women push naturally while lying on their side during childbirth, they feel less pain and less tired than when they hold their breath and push lying on their back — and the baby is just as safe.
