The Effect of Ultrasound Guided Visual Biofeedback Performed by Midwifes on the Duration of the Active Second Stage of Labor, a Randomized Controlled Trial

The goal of this randomized controlled trial is to investigate whether using of coached sonographic pushing will decrease the length of the second stage of labor and the rate of operative deliveries.

Researchers will compare women who undergo the traditional coached pushing to women who undergo visual biofeedback coached pushing.
