ABSTRACT: Objectives: Understand through anatomical model surface electromyography of the stomatognathic system in individuals with and without neuromotor impairment, practitioners and non practitioners of physical activity. Materials and Methods: The study enrolled 20 male subjects, Group 1 (G1) 05 paraplegic athletics practitioners with age mean 31.08±8.36 years, Group 2 (G2) 05 paraplegic who do not practice physical activities with age mean 30.68±6.41 years and Group 3 (G3) 10 subjects without neuromotor impairment with age mean 32.05±9.41 years. These were submitted to an anatomical evaluation by surface electromyography for understanding of the stomatognathic system in the following clinical variables: Rest (RE) and Maximum Habitual intercuspal (MHI). The muscles were: Right and Left Temporal (RT and LT), Right and Left Masseter (RM and LM) and Right and Left sternocleidomastoid (RS and LS). For data collection, were used an electromyography equipment brand Myosystem-I, twelve-channel, portable, and for statistical analysis we used the ANOVA test, using SPSS version 17.0. This project was approved under the rules of law 196/96 CNS, with protocol approval 13/2010 CEP. Results: The clinical condition of rest in the G1 the RT showed 0,095±0,084 μV, in LT 0.081±0,062 μV, RM 0.114±0.098 μV, LM 0.098±0.027 μV, RS 0.575±0.354 μV and LS 0.493±0.303 μV. In G2 the RT showed 0.032±0.021 μV, LT 0.036±0.021 μV, RM 0.051±0.064 μV, LM 0.062±0.05 μV, RS 0.406±0.376 μV and LS 0.479±0.726 μV. In G3, the RT had an average of 0.035±0.016 μV, LT 0.040±0.017 μV, RM 0.485±0.472 μV, LM 0.055±0.056 μV, RS 0.460±0.200 μV, LS 0.530±0.228 μV. In the clinical condition of MHI, in G1 the RT presented 1.542±0.876 μV, LT 1.388±0.434 μV, RM 1.247±0.282 μV, LM 1.573±0.854 μV, RS 1.421±0.957 μV, LS 1.315±0.751 μV. In G2 RT presented 1.034±0.326 μV, LT 1.096±0.374 μV, RM 0.949±0.261 μV, LM 0.998±0.272 μV, RS 1.128±0.838 μV and LS 1.000±0.649 μV. In G3, the RT had an average of 1.296±0.322 μV, LT 1.281±0.351 μV, RM 1.227±0.625 μV, LM 1.276±0.671 μV, RS 1.325±0.604 μV and LS 1.384±0.607 μV. Through the results only the RT and LT variable obtained levels of significance with p value ≤ 0.05 between the groups. Conclusion: This study is instructive for the human anatomy study, demonstrating that the neuromotor not directly infer in muscle activity of adjacent muscle groups, proposing to anatomists and health related areas, a viewing a focal structural context in question, eliminating any general analysis to the case.
