Abstract
The method of stimulating impedance myography (SIM) is based on analyses electrical signals from muscle during contraction registered by means low frequency conductometria of the muscle stimulating by the rising amplitude electroimpulses. SIM is a simple and comprehensive method of express diagnostic work. The form of electric signal from stimulated muscles is identical to form of mechanogramm, but it changes when muscle is damaged.It’s found in experiments that inverted (positive) response results from heterotopic excitation of distant muscle regions under conditions of reduced muscle regions excitability muscle fibers adjacent to the active electrode. Besides, during the propagation of contraction along muscle tissue negative phase of myogramm is followed by positive phase, and two passed response is appeared.Significance of electric conductor spice is also discussed.
