COMPARATIVE RATING OF ELECTROMYOGRAPHS USED IN CLINIC BY MEANS OF EXPERT EVALUATIONS METHOD

Abstract

Electromyographic examination makes it possible to determine the lesion of muscle tissue, the prevalence, severity and nature of the pathological process, therefore, great importance is given to the choice of a high-quality apparatus used in clinical practice. In order to determine the optimal device for electromyography in clinical practice, a questionnaire of 50 questions was compiled to determine the most important parameters of the electromyograph. To confirm the differentiating ability of the questionnaire developed by us, a commission was recruited. In order to confirm the differentiating ability of the questionnaire, a commission was recruited. The expert commission consisted of: 10 specialists from among the teaching staff of the Department of Orthopedic Dentistry with a course in clinical dentistry and 10 other specialists this field from among the teaching staff of the department of Normal Physiology. By the method of expert assessments, the most significant parameters for doctors were selected and their weight was determined. The most significant parameters were: «informative value» and «accuracy», which gained 0.24 and 0.23 points, respectively. An expert assessment of popular electromyographs was carried out: adaptive electromyograph «Synapsis» (NMF «Neurotech» LLC, Russia), electroneuromyograph «Neuro- MVP-8» («Neurosoft», Russia), electroneuromyograph «Neuro-MVP-Micro » («Neurosoft», Russia). The sum of the points of all experts was multiplied by the weight of a certain parameter and entered into tables. After the calculation, the optimal electromyograph was determined. According to the results of the expert analysis of the devices, the highest points were scored by the electromyograph «Synapsis» (Neurotech, Russia): 85.85 points. We believe that in order to obtain the most accurate results in the clinic, this electromyograph can be recommended for medical use as having all important characteristics as being highly reliable.
