The analysis of the uterine contractility in the non-pregnant states provides information about physiological changes during the menstrual cycle. Spontaneous uterine activity was recorded by a micro-tip catheter (Millar Instruments, Inc. USA). The purpose of this study was to compare the results from autoregressive modeling and fast Fourier transform. These methods are commonly used for power spectral analysis. We analyzed 31 uterine contraction signals. Dominant frequency was the test statistics. We did not find statistically significant differences (nonparametric Wilcoxon test for paired samples) between results obtained by means of these two different methods of power spectral analysis.
