Objective: To determine the mathematical relationships between the strength and duration of
the uterine contractions, the descent and rotation of the fetal head and the degree of cervical
dilatation in 50 multiparous women with spontaneous vaginal deliveries using a simple
device applied to the fetal vertex. Method: A simple device for monitoring the progress of
labor was applied to the fetal vertex. The device allows the continuous monitoring of descent
and rotation of the fetal head. The amount of descent and the degree of rotation were also …
