- Functional electrical stimulation device obeying the following steps: Muscle heating - 2 min, 10 Hz, 250 μm; Potentiation of muscle fibers type I - 8 min, 30 Hz, 250 μm; Potentiation of muscle fibers type II - 8 min, 80 Hz, 300 μm; Toning - 8 min, 30 Hz, 300 μm; Muscle Relaxation - 4 min, 5 Hz, 200 μm One channel of electrodes will be placed in the submental region and the other in the thyroid. Treatment should be started at minimum levels of intensity, increasing carefully until appropriate effects are achieved in the procedure. Conventional therapy should be performed in conjunction with functional electrostimulation

-Conventional speech therapy with laryngeal elevation exercises, stimulation of oral reflexes, tongue movements, lips and cheeks, gustatory therapy

Sham.The electrodes are placed at 0 Hz

-Conventional speech therapy with laryngeal elevation exercises, stimulation of oral reflexes, tongue movements, lips and cheeks, gustatory therapy

Anatomical Evaluation:Tongue, palate, pharynx, larynx - normal or specify changes

Functional Evaluation:

• Mobility (lips/tongue), tongue's sensitivity, palatine veil's closure - adequate or inadequate
• Pharynx - salivary/alimentary stasis
• Larynx - normal, decreased mobility, unilateral or bilateral immobility

Deglutition assessment (liquid, thick, pasty and solid foods):

-Delay of swallowing, anterior/posterior escape, stasis in vallecula/pyriform sinuses, laryngeal penetration, laryngotracheal aspiration - present or absent

Functional swallowing: alteration in anatomical or functional evaluation with absence of salivary/alimentary stasis Mild dysphagia: there is also salivary or food stasis in only one consistency with efficient maneuvers such as lowered head, Masako or effortless swallowing Moderate dysphagia: there is also laryngeal penetration to one or more consistencies Severe dysphagia: there is also laryngotracheal aspiration or absence of swallowing reflex

Measured by the Functional Oral Ingestion Scale (FOIS). FOIS results are rated on a scale of 1 to 7 levels. The levels will increase according to the safe amount of oral diet ingested by the patient safely.

Level1 - nothing by mouth; Level 2 - tube dependent with minimal attempts of Food or liquid; Level 3 - tube dependent with consistence oral Intake of Food or liquid; Level 4 - total oral diet of a single consistency; Level 5 - total oral diet with multiple consistencies but requiring special preparation or compensations; Level 6 - total oral diet with multiplex consistencies without special preparation, but with specific Food limitations; Level 7 - total oral diet with no restrictions.

Before feeding:

• Comprehensive language, oral reflexes(vomiting, trismus, deglutition) and sialorrhea- present or absent
• Inside oral and facial sensitivity- present or reduced

During feeding (liquid, thick and pasty):

• Captation, anterior and posterior escape, cough reflex and gagging- present or absent
• Oral transit time, number of swallowing, laryngeal elevation- adequate or inadequate
• Voice normal or "wet"

Functional swallowing- there are changes that do not compromise safe feeding as reduced sensitivity (intra-oral or facial), anterior escape due to small anatomical or functional changes Mild dysphagia- multiple swallowing, inadequate laryngeal elevation, "wet" voice but cough reflex efficient Moderate dysphagia- multiple swallowing, inadequate laryngeal elevation, "wet" voice, weak cough reflex and gagging one or more consistencies Severe dysphagia- when there is no evidence of coughing, swallowing reflexes or gagging difficult to recover
