Abstrakt:	Objective: To analyze the immediate effect of sensory and motor neuromuscular electrical stimulation, in oral and pharyngeal stages of swallowing, in individuals after oral and oropharyngeal cancer therapy. Methods: The study was conducted on 10 individuals (mean age of 58 years) submitted to oral and oropharyngeal cancer therapy. The individuals were submitted to videofluoroscopy, during which they were randomly asked to swallow 5 mL of liquid, honey, and pudding, in three conditions: without stimulation, with sensory neuromuscular electrical stimulation, and with motor neuromuscular electrical stimulation. The degree of swallowing dysfunction was scored (Dysphagia Outcome and Severity Scale), as well as the presence of food stasis (Eisenhuber scale), and measurement of the oral and pharyngeal transit time. The results were statistically analyzed by the Friedman test or analysis of variance for repeated measures. Results: The Dysphagia Outcome and Severity Scale revealed improvement for one individual with both sensory and motor stimuli, and worsening in two individuals, being one with motor and one with sensory stimulus. In the Eisenhuber scale, the neuromuscular electrical stimulation changed the presence of residues to variable extents. Concerning the oral and pharyngeal transit time, no difference was observed between the different stimulation levels for the consistencies tested (p > 0.05). Conclusion: Both sensory and motor neuromuscular electrical stimulations presented a varied immediate impact on the oral and pharyngeal stages of swallowing in individuals after oral and oropharyngeal cancer therapy. Thus, the results of the immediate effect suggest that the technique is not indicated, evidencing the need of caution in the use of neuromuscular electrical stimulation for the rehabilitation of dysphagia, after HNC treatment.
