Abstract
ABSTRACT Objective: to investigate the knowledge of speech therapists about the physiology of exercise in orofacial motricity. Methods: 38 speech therapists working in orofacial motricity in the state of Sergipe, Brazil, graduated from institutions of higher education in Brazil, answered eleven closed questions about the type of exercise, frequency, time of muscle contraction, serial number and signs and symptoms of muscular fatigue. The results were analyzed by the Kolmogorov-Smirnov and Chi-square tests (5% significance). Results: the variation of the exercises regarding the time of contraction was cited by the majority (89.47%) and the serial number throughout therapy by all the participants. There was a 60.52% improvement on the isometric and isotonic exercises, 55.26% on the application of exercises in asymmetries and 47.34% on the sequence of exercises according to the type of muscular contraction. The majority of the participants conducted home exercises for more than three days a week (73.69%), and .63% participants indicated the interval time between one minute and two minutes. The most commonly reported signs and symptoms of muscle fatigue in the face were tremor / fibrillation (78.95%). Conclusion: the knowledge of the study group about the physiology of exercise still lacks greater technical-scientific subsidies.
Highlights
Orofacial motricity, with the purpose of reestablishing the oral functions, appropriates two lines of reasoning: myotherapy and myofunctional therapy[1]
For the composition of the sample, a sample calculation was made based on the number of speech therapists in the state of Sergipe (n = 304), according to the search conducted in September 2016, on the page of the Regional Speech, Language and Hearing Sciences Council (4th Region)
When analyzing the data referring to the knowledge of speech therapists about the exercises used in clinical practice and their sequence of application, it was verified that there is little applicability of the physiological parameters in the choice of these exercises
Summary
With the purpose of reestablishing the oral functions, appropriates two lines of reasoning: myotherapy and myofunctional therapy[1]. Myotherapy aims, through specific exercises, to modify muscular behavior, while myofunctional therapy works directly with the oral functions that are to be adapted, aiming at muscle modification[2]. These muscle modifications occur due to the characteristics of the skeletal muscle tissue, since it has a voluntary contraction and is fixed in the skeletal system. It is composed of muscle fascicles, that is, groups of muscle fibers composed of myofibrils and these, of myofilaments that slide between them during muscle contraction[3]. The isometric approach, occurs when the two muscular extremities are fixed, determining the increase of tension or force, without shortening the muscle or perceivable movement[5]
