Rapid Syllable Transition (ReST) Interventions for Speech Sound Disorders in Children

Sponsor: Aline Mara de Oliveira

Summary

This study will investigate the feasibility of applying the Rapid Syllable Transition Treatment (ReST) protocol in children with Childhood Apraxia of Speech, considering the scarcity of evidence in the context of Brazilian Portuguese and the need to implement evidence-based interventions in clinical practice. The objective is to evaluate the feasibility of the protocol and estimate preliminary effects on articulatory accuracy, prosody, and speech motor planning. This is a randomized clinical trial with a quantitative and qualitative approach. Participants will be children between five and twelve years old, diagnosed with Childhood Apraxia of Speech. The intervention will be carried out over six weeks, with two weekly sessions, using pseudowords structured according to the ReST protocol. After an initial assessment, participants will be randomized to an intervention group or a control group on a waiting list. Pre- and post-intervention assessments and a one-month follow-up will be conducted. Data analysis will be exploratory, focusing on evaluating the feasibility of the procedures and estimating parameters for future studies. Primary outcomes will include feasibility indicators such as recruitment rate, adherence, therapeutic fidelity, acceptability, and retention. Secondary outcomes will include preliminary measures of speech performance and effect size estimation. The results are expected to provide preliminary effect estimates and inform the design of a definitive randomized clinical trial.
