Existe relação entre funcionalidade de membros inferiores em atletas de beach-soccer com disfunção temporomandibular?

Abstract

Introduction: Recent studies suggest that there is an interesting relationship between the stomatognathic system and the musculoskeletal system, and point out the influence of this system on stability, balance and posture. Objective: The objective of the present study was to verify if there is a relationship between the functionality of lower limbs in beach-soccer athletes with temporomandibular dysfunction (TMD). METHODS: This was a cross-sectional study, with professional beach-soccer athletes, who responded to the Diagnostic Criteria for Temporomandibular Disorders Research (RDC / TMD) to identify if they presented TMD, were later divided into two groups; group without TMD. The athletes in the group who presented the dysfunction responded to the Anamnestic Index of Fonseca (IAF) that evaluates the TMD as to its severity. After allocation of the groups, they individually performed a dynamic balance test (Y-Balance Test) and two types of vertical jumps (SV) to evaluate their functionality. Statistical analysis: The normality of the data was evaluated using the Shapiro Wilk test and expressed as mean and standard deviation. The level of significance was 5% in all comparisons and statistical analyzes. The Pearson correlation test was performed for intragroup analysis and the independent Test T for analysis between groups. Results: In the intragroup analysis, a strong correlation was observed when compared to the severity of the TMD with the measurements obtained in the dynamic equilibrium (Y-TEST). When DTM was correlated with the variables of vertical jump tests such as height and power, correlations were observed, but without statistical significance. In the analysis between groups, athletes who did not present TMD showed better results of functionality, balance and lower limb potentials than athletes with some type of TMD. Conclusion: It was possible to conclude from the results of the present study that physically active beach-soccer athletes diagnosed with TMD present a reduction in the functionality and dynamic balance of the lower limbs, which aggravates the more severe the TMD. However, regarding the jump tests, there was no statistical difference when compared to the beach-soccer athletes of the control group.
