Brief summary

The original aspect of the methodology proposed for this study concerns the use of as many as 16 electrodes to study the propagation and coordination (or synchronization) of uterine contraction. Over the last two years, the Compiègne University of Technology and the University of Reykjavik (Iceland) teams have developed the tools required to obtain good quality signals during electrohysterography and have worked on filtering and mapping of uterine electrical activity derived from these signals.

Design outcomes

Primary

Measure	Time frame	Description
parameter H2	H2 value measured at each contraction during 1 hour	To demonstrate a difference of propagation of the electrical signal during a physiological contraction of pregnancy and uterine contraction during delivery. The parameter H2 (nonlinear correlation coefficient) will be used to measure propagation of the electrical signal.
