Tracking Speech Pathology with FlexiForce

Speech pathologists track the progression of speech therapy by incorporating FlexiForce sensors into their pressure measurement device.

Speech Pathologists Track Progression of Patient’s Speech Therapy with FlexiForce™

Traditionally, speech pathologists evaluate the health of orofacial muscles by asking a patient to contract their tongue against an imposed object, such as a gloved finger. In recent years, pathologists have sought more precise methods of quantifying these contractions in order to improve diagnoses of muscular diseases and measure a patient’s progression during speech therapy.

Challenge: Quantifying force and pressure measurements in speech pathology patients

Specialists and doctors routinely assess the study of orofacial structures in a qualitative manner leaving room for human error. Quantifying the force and pressure of the structures provides a better diagnosis of muscular diseases pertaining to the mouth and face. In 2002, a professor and group of speech pathology students joined the Biomechanic Engineering Group from the Universidade Federal de Minas Gerais in Brazil to study and improve the assessment of orofacial structures. The team sought to design a device that would quantify the force and pressure of the orofacial structures, specifically the tongue and lips.

Solution: Incorporating FlexiForce sensors into the mouthguard

The team of engineers and students worked together to design a mouth guard, the FORLING, that properly measures a patient’s tongue protrusion force. The group integrated the FlexiForce™ A201 sensors into the mouth guard in order to quantify the force measurements. The FORLING is a lightweight, low cost, reliable mouthpiece that is then connected to a data acquisition system. The inner surface of the mouthpiece contains a base, an A201 force sensor, an applicator pin, a holder, and a force applicator. The data acquisition system creates a patient profile after recording the patients tongue measurements three times. The acquired data allows speech pathologists to track their patient’s progress during speech therapy.
