Abstract

The possibility that a change of the stomatognathic system can influence postural control is a controversial topic in the literature, and also needs to be better understood. Thus, the aim of this study is to investigate the influence of mastication on postural control in individuals with temporomandibular disorders (TMD) using kinematic and stabilometric parameters. Will be part of this pilot study, 14TMD patients (male and female) aged between 18 and 40 years. To verify if there is any influence of mastication on postural control will be used stabilometric and three-dimensional kinematics parameters, which will be collected with the individual in a static position on a force platform for 40 s at rest (PRE-M) followed by a period chewing 35s (DUR-M) and for 40 s after chewing (POST-M) (total = 125 s). For every moment will be selected masticatory 30 seconds of the signal data. To stabilometric parameters will be calculated area of center of pressure displacement, velocity and frequency of oscillation. The three-dimensional kinematic parameters will be obtained by means of 31 spherical retro-reflective markers to be attached with double-sided specific anatomical points that serve as reference for the capture system analysis of movements (angular displacement) of the head, trunk, hip and anklein, PRE-M, M-DUR and POST-M conditons. The averages of the data will be organized and presented in graphs and / or tables. For the analyzes will be considered the value of p <0.05.
