Rhythmic fetal movements

In recent years, studies have confirmed that rhythmic movement of the fetal torso occurs. These movements have been investigated with respect to a large number of factors, but no conclusive evidence of their significance has been documented. Much effort has been directed at developing better methods of measuring these movements. In this paper, examples of preliminary clinical results utilizing an advanced real-time B-scan phase-locked tracking scheme are presented. These traces represent a significant advancement in our ability to record rhythmic fetal torso movements and should enable us to enhance our knowledge of the physiology and clinical significance of this phenomenon.
