Abstract
Electromyographic substantiation of feasibility of application of myorelaxing tires of EXOCAD technology in the treatment of tempoal-mandibular joint (TMJ) dysfunction. Our study allowed us to trace and analyze changes in the chewing muscles of patients that occur during the treatment of TMJ dysfunction and indicate its effectiveness. In patients with TMJ dysfunction, qualitative and quantitative indicators of electromyography closely correlate with the stages of development of pathology and correspond to its clinical manifestations. In this study, for the first time, the relationship between changes in the parameters of the frequency of muscle contractions and the subjective sensation of pain in the area of the specified chewing muscle in patients was analyzed. The purpose of this study is comparative analysis of the nature and degree of changes in electromyographic activity of the main and auxiliary chewing muscles in patients with TMJ dysfunction before and after the use of myorelaxing spleen. TMJ dysfunction five-year study covered 274 patients, which were divided into 3 clinical groups (CG I–III). The general analysis provided 1024 electromyograms before and at the stages of patients’ treatment. The results of the analysis of the effectiveness of the use of myorelaxation tires in the treatment of TMJ dysfunction can improve the quality of treatment of this pathology in patients. The results obtained after 12 months indicate that the effectiveness of treatment of patients with CG I (with the lowest intensity of symptoms of TMJ dysfunction) reached 89.1±1.3%; CG II – up to 78.3±1.3%; CG III – 77.3±1.3%.
