The positive aspects of using the EMG biofeedback as an adjunctive method in cases of neurogenic dysphagia may pose this technique as a facilitator in terms of learning new neuromuscular patterns for swallowing, so as to provide the patient with a higher gain, as compared to the conventional therapy, as well as a probable longer effect of rehabilitation, since the EMG biofeedback involves the change of a
