Neurogenic dysphagia encompasses the disturbances in swallowing that occur because of a neurological disease, with the symptoms and complications stemming from the sensorial-motor impairment of the muscles involved in the swallowing process. This type of dysphagia is particularly debilitating. It can cause death or increased health care costs due to tracheal aspiration. This pathology is common and it presents a potentially fatal complication for stroke, happening in approximately 50% of these patients. Among the possible treatments, tactile-thermal stimulation and biofeedback are frequently successful, varying from 0% to 83%. Studies register a high success rate for this treatment with patients that have suffered strokes, which doesn’t usually include the most severe dysphagia. The use of the electrical stimulation in treating dysphagia was first reported in 1996 by Freed et al and, later, by Park et al. The objective of the electrical stimulation was to find an afferent branch for the swallowing reflex in stroke patients with dysphagia associated with delayed initiation of swallowing. Since this was a little-explored alternative treatment, the objective of that study was to perform a bibliographical review concerning the use of electrical stimulation in the treatment of dysphagia in patients that had suffered strokes. Conclusion: Dysphagia caused by stroke is directly associated with an increase in life-threatening medical complications and requires the attention of health professionals. Electrical stimulation is an important therapy for dysphagia and its effectiveness in this pathology must be explored.
