Terapia de Entonación Melódica para el aspecto expresivo en afasia no fluente pos-ACV: Una revisión sistemática.

Melodic Intonation Therapy emerges as a promising alternative for the recovery of oral expression in patients with non-fluent aphasia following a stroke, by engaging language-capable regions in the right hemisphere when the left hemisphere is affected. The objective of the present study was to characterize the expressive aspect of language in patients with non-fluent aphasia after a stroke who received Melodic Intonation Therapy, in comparison with control groups. A systematic search was conducted in Medline (PubMed), LILACS, and SciELO. A total of 29 articles were identified, of which 7 met the eligibility criteria. Overall, better outcomes were observed with Melodic Intonation Therapy compared to controls, particularly in trained elements, while results for untrained elements and functional communication were less consistent. The findings presented here support the potential use of Melodic Intonation Therapy as a therapeutic option to improve the expressive aspect of language in patients with non-fluent aphasia following a stroke; however, greater homogeneity in interventions, assessments, and outcome measures is needed to enable meaningful comparisons.
