Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Children with Down syndrome (DS) have language development particularities that have negative effects in the communication capacity. By this way, Augmentative and Alternative Communication (AAC) is indicated to this population. The aim of this study was to verify the AAC impact in the lexical gain of children with DS.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Five children with DS, with the same cognitive level, participated in this study. Longitudinal follow-up of twelve months of speech-language therapy with AAC use was undertaken. A lexical evaluation was done at the beginning and the end of this follow-up. Correct responses in the lexical evaluation were increased, but not necessarily in the spoken modality. The comparisons showed significant results in use of substitutions processes, and to no-answers.
