Abstract

Principles and methods of artificial movement correction (AMC) with muscle electrostimulation during pathologic gait were considered. It was shown that the most important peculiarity of AMC was phase conformity of artificial and natural irritation as well as construction of muscles at movement. Electrostimulation in M zone, when muscle activity at movement is the maximum one, is obligatory. The main functions of AMC were detected: i.e. therapeutic, diagnostic and prognostic. Indications and contraindications for FMC application as well as technological operation were determined. Clinical and instrumentation evaluation of AMC results in certain pathologic changes of loco-motor system, i.e. crus stump, I—II degree of scoliotic deformity, non-union and pseudoarthrosis of bone crus is given.

M — maximum activity, Y — moderate activity, H — low-amplitude activity; 1 - calf muscle, 2 - tibialis anterior, 3 - wide external, 4 - semitendinosus. Below the graphs is a subgram (designation of the phases of the step): a - heel, b - foot, c - toe, d - transfer). Here and in other figures: along the abscissa axis - time (in% of the duration of the double step), along the ordinate axis - the average electrical activity (в мкВ).
