Effects of using the stimulating palatal plate in combination with orofacial stimulation on the habitual tongue and lip posture in children with trisomy 21: an integrative literature review

Abstract

ABSTRACT Purpose: to verify, in the literature, the effects of using the stimulating palatal plate on lip and tongue posture in children with trisomy 21. Methods: a search was conducted in Medline, LILACS, CINAHL, EMBASE, Scopus, Web of Science, and Cochrane. Original articles designed as clinical trials, longitudinal studies, or case-control studies, approaching stimulating palatal plate in the treatment of children with trisomy 21 and assessing habitual lip and tongue posture as an outcome, were included. Literature Review: a total of 376 studies were found, of which 10 met the selection criteria. They were published between 1996 and 2007 and carried out mostly in Europe, with small samples. The age when they began wearing the plate ranged from 1 month to 5 years, and intervention lasted from 4 to 58 months; in most cases, it was combined with orofacial muscle stimulation. Use frequency ranged from two to four times a day, each period lasting from 30 minutes to 2 hours. The children’s tongue and lip posture improved in most pieces of research. Conclusion: studies suggest that using the stimulating palatal plate in combination with orofacial muscle stimulation brings benefits to tongue and lip posture in children presented with trisomy 21.
