Avaliação eletromiografia de músculos posturais e da mastigação em musicista de sopro

Abstract

Fixator muscles are necessary and essential for maintaining an ergonomic and stable posture. Observing the electrical activity of cervical, humeral and masticatory muscles in wind musicians can identify some patterns of muscle alterations such as fatigue and tension, making it possible to intervene to optimize the performance and health of these professionals. The electromyographic test was used to evaluate the muscles. Through this test, it was possible to examine the involvement, necessary adaptations and possible muscular alterations that directly interfere with posture and the work of the locomotor system, commonly added to pain conditions. In order to play a wind instrument, it is necessary to adjust the posture of the head, shoulders and consequently the neck and jaw. Aware that a change in the position of one lateral axis of body balance will lead to a disruption of all the others, the aim of this study was to understand the muscular activity of the musician in order to better prevent, diagnose and treat postural and consequently occlusal inaccuracies, with or without pain. In addition, mandibular posture/position is essential for breathing and breath control in wind musicians. For this analysis, electromyographic data was collected from the masseter, deltoid and trapezius muscles, bilaterally, in resting and active situations (chewing and MIH), from a musician who practices the transverse flute and from 5 other volunteers who made up the control group. Statistical analysis was carried out using the Student's t-test with p<0.05 to compare the mean of a group with a parameter, and the data was also subjected to a percentage description. After collection, it was observed that the musician's right masseter and trapezius muscles showed greater electrical activity than the control group in all collection situations. We therefore conclude that the musician has increased electrical activity in the muscles of the cranial cervical humeral complex due to fatigue and also due to postural inaccuracies caused by excessive muscle work.
