The article considers a number of modern methods for processing the signal of electromyography in problems of controlling the upper extremity prosthesis. The parameters of the time domain, the computational complexity of the estimation algorithms which are the minimum ones, are chosen as the investigated. The signal was recorded on a patient who performed six movements. Using the MATLAB software package, the methods for processing the electromyogram signal are investigated. The choice of the most informative parameters is a necessary component of the development of the artificial limb control algorithm, because due to the correct processing of the signal it is possible to control the parameters of the upper extremity prosthesis, for example, by brush strength.
