This work presents the development of a system for the measurement of the axial forces produced by the human tongue. A prototype was developed which reproduces the underlying principles of the methods normally adopted in clinical procedures, with the advantage that it allows the phonoaudiologist to obtain objective measurements of these forces. This work also presents an analysis based on the repeatability and the reproducibility of the forces in an attempt to select which of these forces can be employed as parameters for diagnosis and as success indicators of therapies. Preliminary results indicate the mean force as the most reliable parameter.
