Abstract. One of the ways of search for signs of Parkinson's disease (PD) is a joint analysis of signals of different modalities. It is an electroencephalogram (EEG), electromyogram (EMG) and mechanical tremor (MT) measured using accelerometers. Frequency synchronization of EEG, EMG and MT can be estimated by the frequency - temporal distribution of the extremes of wavelet spectrograms of the EEG, the MT and the shape of amplitude-modulated high-frequency EMG.

Key words: Parkinson's disease, mechanical tremor, electroencephalogram, electromyogram, accelerometer, frequency synchronization, wavelet spectrogram, shape of the EMG.
