Abstract: The efficiency of time-frequency method in informative qualitative and quantitative estimation of human neuromuscular system functional condition has been proved by researches with the help of normal and pathologic global electromyogram processed by the method of time-frequency transformation. The regularities of frequency parameters of normal and pathologic electromyogram signals are established. The numerical criterion for estimation of human neuromuscular system functional condition is offered. The results of this work is of great interest for developers of the electromyography systems.

Keywords: electromyography, global electromyogram, neuromuscular system, non-stationary system, biomedical signal, shorttime Fourier transformation, time-frequency analysis, spectrogram
