Abstract
In this paper, we review modern nonlinearity methods that can be used in preterm birth analysis. The nonlinear analysis of uterine contraction signals can provide information regarding physiological changes during the menstrual cycle and pregnancy. This information can be used both for preterm birth prediction and preterm labour control. Both the contractions in different topographic regions of the uterus and the time delays between uterine contractions are essentially nonlinear events, so we have suggested the most appropriate nonlinear dynamics methods and patents.
