[Contractile activity of the uterus in different variants of cervix dilatation and fetal forward movement during labor]. 1991

S L Voskresenskiĭ, and S T Zavtrak

The biomechanism of labour pains was examined by analysing the amplitude, frequency, and duration of the pains during labours accompanied by arrests in the course of cervical dilatation and fetal forward movement. The forces driving out the fetus from the uterus were shown to be formed of two components: 1) uterine wall muscular layer tension and 2) amniotic fluid hydraulic pressure, the former being of greater importance than the latter.
