VitalStim is an electrotherapy device used in the rehabilitation of swallowing disorders (dysphagia). It provides non-invasive, sensory or sensory-motor stimulation to the structures involved in swallowing, by stimulating the swallowing reflex. It speeds up the recovery process.
The stimulator screen continuously displays the electrical activity of the muscle, which is also converted into sound signals. Therefore, rehabilitation sessions are interactive; they enable patients to have both visual and auditory feedback of their swallowing process.
