BACKGROUND: Dysphagia causes severe complications among people with a stroke. Physiotherapy allows the cure of this pathology, and among the tools it offers is neuromuscular electrical stimulation. However, this is a technique that has not been protocolized. Therefore, it was considered necessary to carry out a systematic review on the efficacy of the various parameters of application of the neuromuscular electrical stimulation in dysphagia generated after a stroke. METHODS: A systematic search for publications was conducted in March 2020 in the PubMed, CINAHL, Medline, Web of Science and Scopus databases, using as search terms: electric stimulation therapy, deglutition disorders and stroke. RESULTS: 21 articles were obtained in which the application of neuromuscular electrical stimulation was applied in isolation (n = 7) or in combination with other techniques such as strengthening exercises and manual therapy techniques (n = 14), with this second modality of treatment having greater benefits for patients. CONCLUSION: The greatest efficacy of this technique is reached when applied at 60 to 80 Hz, 700 micro-s of pulse duration, at the motor intensity threshold and in sessions of 20 to 30 min.
