Speech Supplementation Strategies for Improving Intelligibility in Children With Cerebral Palsy (CP)
University of Wisconsin, Madison
Summary
The goal of this clinical trial is to learn if speech supplementation can improve speech intelligibility in children ages 7 to 17 years with cerebral palsy. The main questions it aims to answer are: * To what extent can speech supplementation improve intelligibility in children with CP compared with habitual speech produced without speech supplementation? * How much intelligibility change is necessary for meaningful improvement when children use speech supplementation strategies? Participants will: * complete speech and language assessments * complete a speech pre-test using habitual speech * learn a speech supplementation strategy with training from a speech-language pathologist * complete a speech post-test using the speech supplementation strategy * complete a speech repetition task where specific words are emphasized (emphatic stress) * use the previously learned speech supplementation strategy + emphasis on specific words while producing a set of sentences
Description
This study uses a pre-/post- test design to test the effects of a one-session intervention to improve speech intelligibility in 100 children with cerebral palsy and dysarthria. The intervention involves the augmentative and alternative communication (AAC) strategy known as speech supplementation. Specifically, children will learn how to simultaneously speak and point to the first letter of each word on a communication board, or to speak and point to a topical picture on a communication board. The strategy serves to provide listeners with context cues for spoken words, and it also serves to imp…
