Analysis of changes in electromyographic masticatory muscle activity in relation to the selected correction of refractive error

Wearing glasses is safe, effective, and the most popular method in correcting myopia. The study aimed to analyze the changes in electromyographic activity of the masticatory muscles about the selected correction of refractive error. Two muscle pairs were analyzed: the anterior part of the temporalis muszle and the superficial part of the masseter muscle. The patient was fitted with 20/200, 20/40 20/20, 20/10 corrections of refractive terror, and during each correction of refractive error, the changes in the recording of bioelectrical activity during rest, during maximal voluntary clenching, during maximal voluntary clenching on dental rollers were analyzed. With greater correction of refractive error, resting temporal muscle activity increases. Appropriate correction of refractive error may be an option in the treatment of masticatory muscle pathology. This phenomenon requires further research.
