SELECTION CRITERIA: The research criteria selected in the database were: studies in the past five years and studies in humans. In the pre-selection, studies that were duplicate, not fully available, and have shown no direct relation with electropalatography in speech-language therapy were discarded.

DATA ANALYSIS: Data analysis was performed descriptively, following subdivisions: title, area, year, subject, implementation, and conclusion of the study.

RESULTS

Twenty one papers were selected, eight of them using the term electropalatography, two with the keywords electropalatography AND evaluation, six with the keywords electropalatography AND therapy, three of them with the keywords electropalatography AND ultrasonography, and two papers with the keywords electropalatography AND speech.

CONCLUSION

Different types of research involving the use of electropalatography in the field of speech-language therapy were found and analyzed. Few researches have concomitantly used electropalatography and ultrasonography.
