Maternal perception and Doppler detection of fetal movement.

Fetal movement can be used as a tool for assessment of prenatal well-being. Maternal perception of fetal movement, using a formal graphic "count-to-ten" system is often used as an adjunct in high risk and normal pregnancies. Doppler detection of fetal movement is a newly introduced, easy to perform methodology. Identification of coupling fetal heart rate accelerations to fetal movement as an aid for nonstress testing and recognition of fetal behavior, fetal behavioral states and cycling between states, is a current clinical application of this new technique.
