Abstract: 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 60-80 Hz, 700 ?s of pulse duration, at the motor intensity
threshold and in sessions of 20?30 min.
