Synthesis of electrostimulation signals based on time-frequency analyses of electromyograms

The research results of surface electromyograms (EMG) characteristics of human skeletal muscles, recorded during typical movements are introduced. The most dominant frequencies in the EMG spectrum, during the influence on a muscle, as well as the patterns of change in the EMG spectrum with an increase in the force developed by a muscle, are discovered. It was suggested to synthesize electrostimulation signals into a system with biotechnical feedback, using the discovered patterns.
