The Miles Circuit: This circuit is useful to help get the baby lined up, ideally, in the "Left Occiput Anterior" (LOA) Position, both before labor and during labor. Prenatally, this position set can help to rotate a baby. As a natural method of induction, this can help get things going if baby just needed a gentle nudge of position to set things off. In labor, if labor seems to be not progressing. mom has back labor, or the postion is determined to be not LOA.
