[Application of surface electromyography in patients with functional disorders of the masticatory muscles]

To compare the results of surface electromyography in patients with functional disorders of the masticatory muscles at all stages of complex therapy and to demonstrate the need for the introduction of a generally accepted comprehensive approach to the examination and treatment of patients with this pathology.

EMG studies were conducted in 127 patients of both sexes aged 35 to 54 years, who were divided into 2 groups. The first (control group) consisted of 20 patients without signs of functional disorders in the masticatory muscles. The second (main) group included 107 patients of both sexes with functional disorders in the masticatory muscles. The examination was carried out using a portable electromyograph "Synapsis" (Neurotech), adapted for dental purposes.

The application of surface electromyography in patients with functional disorders of the masticatory muscles revealed statistically significant differences in the values of the compared indices. EMG allowed for a visual assessment of the work of the masticatory musculature based on the results of qualitative and quantitative indicators of the bioelectrical activity of the masticatory muscles.

Performing surface EMG at all stages of rehabilitation is of undeniable value as the most accessible and informative method for diagnosing neuromuscular disorders in patients with increased tooth wear and masticatory muscle dysfunction, which improves the quality of orthopedic treatment.
