Up-to-date approach to electrostimulation of neuromuscular structures of the skeletal muscles of man is discussed in the article. The authors analyse informative for bioregulation parameters of the object of electrostimulation. Two variants of realization of biomonitored electrostimulation, with an automated length of exposure and with arbitrary electrostimulation monitoring of motor activity, are described in the article. The data on the new biomonitored electrostimulators Bion-4, Bion-7, Electromyoplethysmograph are presented.

Multichannel electrostimulators are used for electrostimulation of some groups of muscles. A number of requirements should be borne in mind when designing such devices: the structure of the signals for multichannel electrostimulation must be physiological; the interaction between the channels must be eliminated; the energy of the electrostimulation must be measured; the impedance of the electrode-skin system must be stabilized; a method of electrode electrostimulation, not involving wetting, is to be developed.

The application of the unit for electric stimulation of the neuro-muscular system with the use of a selected stimulus permits it to produce contraction of the muscles with the minimal energy of the stimulus and the least possible pain sensation. As such a stimulus serves a radio-pulse with a carrier frequency of 10 kHz and having a form enveloping the impulse emerging in the motor fiber. These stimuli are produced in electric stimulators of the type "Bion".
