Dysphagia can reach a prevalence of up to 80% in intensive care patients. The implementation or prolonged presence of medical devices such as the intubation tube, tracheostomy, or nasogastric tube alters the physiology of swallowing and causes local injuries at several levels. Additionally, certain medical treatments impair swallowing physiology and the patient's alertness, further promoting the development of these disorders. Management of dysphagia involves two main types of strategies: adaptive or compensatory maneuvers and rehabilitation techniques such as: performing praxis or swallowing exercises; physical stimulation (tactile or thermal); transcranial stimulation (electrical or magnetic); and finally, pharyngeal or transcutaneous electrical stimulation (NMES). Patients hospitalized in intensive care often present with altered levels of alertness, asynchronous ventilation and swallowing, and reduced motor capabilities, making it difficult to perform techniques like praxis, food trials, or resistance swallowing exercises. NMES does not require active patient cooperation or the permanent presence of the therapist during the stimulation session, thus increasing the intensity of dysphagia rehabilitation and the early implementation of treatment in these patients, complementing conventional rehabilitation. Muscle and sensory stimulation through the application of NMES can help increase the strength of the muscles involved in swallowing and improve sensory capabilities. However, its effects have not yet been evaluated in tracheostomized patients undergoing weaning from prolonged mechanical ventilation.
