Biofeedback Rehabilitation to Improve Speaking and Eating in Public

The study agent is electropalatography (EPG). The LinguaGraph EPG device is a biofeedback technology that creates a digital visualization of tongue function during speech. The visualization is accomplished by a custom made mouthpiece that fits over the hard palate with 62 sensors that capture tongue position. The information from the sensors in the mouthpiece, as well as the audio output, is processed in an EPG Unit that converts the information from mouthpiece to a visual representation on a computer screen. The visual information with respect to tongue position can be used to provide biofeedback training.The computer can be used in the clinic during a patient visit or it can be seen over the internet with the patient at home and the speech and language pathologist at the clinic.
