THE ROLE OF ELECTROMYOSTIMULATION IN THE PREOPERATIVE PREPARATION OF PATIENTS WITH ANTERIOR CRUCIATE LIGAMENT INJURY AND ARTHROGENIC MUSCLE INHIBITION

Abstract

Aim. This study aims to evaluate the efficacy of electromyostimulation (EMS) of the quadriceps femoris muscle on force plate measurements and blood circulation in patients with anterior cruciate ligament injury and arthrogenic muscle inhibition. Materials and methods. Based on electromyography (EMG) findings (Viking Quest, Nicolet), patients were allocated into 2 groups: those with normal and those with reduced EMG parameters in the affected limb. Patients exhibiting reduced EMG activity underwent a preoperative course of passive electromyostimulation of the quadriceps femoris muscle (10 sessions). The intervention’s efficacy was assessed through force plate measurements (Hawkin Dynamics) and rheography (RHEO-SPECTRUM). Results. The application of EMS to the quadriceps muscle of the injured limb resulted in a significant reduction in peak force asymmetry between the healthy and affected limbs and was associated with improved peripheral blood circulation and enhanced venous outflow. Conclusion. Electromyostimulation of the quadriceps femoris muscle is an effective preoperative intervention for patients with anterior cruciate ligament injury and arthrogenic muscle inhibition, facilitating subsequent postoperative rehabilitation.
