Pre-labor Ultrasound as a Visual Biofeedback Device for Maternal Pushing Education

The study will observe the effect of antenatal biofeedback with transperineal and abdominal ultrasound applied by a pelvic floor physical therapist. The training will focus on pelvic floor training and maternal-coached pushing with ultrasound-based visual biofeedback. The investigators aim to assess maternal and neonatal obstetrical outcomes, urinary and fecal incontinence, and maternal psychological effects.
