Signal processing methods in the analysis of the uterine contractility

Abstract

The aim of this study is to evaluate synchronization of signals representing uterine contraction activity by means of linear signal processing methods - power spectrum, coherence measure, wavelet power spectrum and wavelet coherence measure. We present results of this analysis for patients with primary dysmenorrhea, uterine myomas, endometriosis and for a healthy woman. Using these methods we have found that primary dysmenorrhea, endometriosis and uterine myomas are accompanied by the uterine contraction disorders. Our analysis will allow more precise diagnostics and better control of treatment. © 2010 International Federation for Medical and Biological Engineering.
