DYNAMICS OF BIOMECHANICAL INDICES OF THE FUNCTIONAL STATUS IN PATIENTS AFTER TOTAL ARTHROPLASTY ON THE BACKGROUND OF ARTIFICIAL GAIT CORRECTION
The present research aimed at the analysis of the results of rehabilitation of patients after total arthroplasty of large joints. Assessment of the state of locomotor system condition was carried out with the help of biomechanical parameters calculated by stabilometric, electropodographic and dynamometric methods. The following podographic parameters demonstrated the most significant positive dynamics: 1) the rhythmicity coefficient, which was 0.93–0.94 before the rehabilitation approached the norm 0.95–1 (p <0.05) after the rehabilitation; 2) the step cycle which had been 0.9-1.6 sec. before stimulation reached the normal range, i.e. 1–1.4 sec. (p<0.05) after stimulation; 3) stabilometric parameters (the position of the pressure center in the frontal and sagittal planes, the length and area of the statokinesiogram, as well as the extremes of the vertical component of the support). Rehabilitation was performed by artificial gait correction through complex muscle electrical myostimulation. The functional results of patients after gait correction sessions were evaluated as excellent (30 %), good (48 %) and satisfactory (12 %). Thus, artificial gait correction method with the help of controlled electromyostimulation allows improving the state of kinematic and locomotor function of the musculoskeletal system in patients after total arthroplasty of large joints.
