- Аннотация: An investigation of the 0.5-4 Hz little-studied frequency range of accelerationsignals (ACC) was performed in patients with Parkinson’s disease (PD) and essen-tial tremor (ET). In this frequency range, new neurophysiological regularities wererevealed. A new method was used to analyze the wave train electrical activity ofthe muscles based on the analysis of Morlet wavelet spectrograms and ROC curves.The method idea is to find local extrema (named wave trains) in the Morlet waveletspectrogram and to calculate various parameters describing these wave trains: thenumber of wave trains per second, the duration of the wave trains in periods, theleading frequency of the wave trains, the width of the wave train frequency band.The AUC functional dependence on the values of the bounds of the ranges of theseparameters is investigated. This method is aimed at studying changes in the time-frequency parameters (the shape) of signals including changes that are not relatedto the power spectral density of the signal
