La fuerza lingual como una característica clínica de la salud oral en pacientes neurológicos: Una Revisión Sistemática.

Abstract

Objective: Current oral health assessment has a compre-hensive view of the relationship between hard and soft tissues of the mouth as seen by orthodontics and prosthodontics in a healthy population. Despite knowing the influence this relationship has on functional outcomes such as swallowing and mastication, motor evaluation of soft tissue such as the tongue is still scarce. This lack of knowledge is even greater in individuals with a neurological condition. In this sense, the measurement of lingual strength has been addressed by some research as a key element accompanying oral rehabilitation in healthy populations. Acknowledging the importance of tongue strength in oral biomechanics, the Iowa Oral Performance Instrument (IOPI) has become a gold standard instrument. The purpose of this article was to search for scientific studies on tongue strength using the IOPI as a research tool in populations with neurological conditions, to know about its inclusion in the clinical practice and comprehensive oral health rehabilitation in this population. Material and Methods: A systematic search in five major databases was carried out based on the PRISMA Protocol. Searches were conducted in the PubMed, Medline, Lilacs, Web of Science and MedCarib databases including articles from 2007 to 2020. To generate the search in each database, three main constructs were developed: (1) "tongue strength IOPI"; (2) "Swallowing Disorders"; (3) "Neurological Diseases". Results: 152 studies were identified, 14 were included in the final review. The PEDro scale showed great heterogeneity in the level of evidence between the studies with only 5 RCTs and only two of them on lingual strength training. Conclusion: The IOPI was used mainly to measure tongue strength and only 36% as a clinical training device, which could contribute to improving oral health. The stroke was the most represented (79%).IIIISU.
