Each participant will attend 5 sessions per week for a total duration of 5 weeks. The duration of each session will take 1 hour, including bio-feedback preparation that will take about 10 minutes for assembly and 5 minutes for removal. At the beginning of the bio-feedback session, a surface electrode will be applied to the mylohyoid muscle. The computer will analyze the electromyographic signal of the patient in real time and will produce visual feedback of the muscular activity on the screen. The patient will be required to swallow at a given time, with food bolus if possible, and perform maneuvers that favor swallowing strength and efficacy.
