What you need to know

  • Reduced fetal movements are associated with adverse pregnancy outcomes in pregnancy, including stillbirth, fetal growth restriction, placental insufficiency, and congenital malformations

  • Perform clinical assessment of a woman with reduced fetal movements including symphysis-fundal height measurement and fetal heart auscultation
