The Efficacy of Dynamic Temporal Tactile and Cueing Treatment Versus Rapid Syllable Transition Training on Speech Intelligibility in Children with Apraxia
The purpose of this proposed single-subject study will be to investigate the effects of Dynamic Temporal Tactile and Cueing Treatment (DTTC) and Rapid Syllable Transition Training Treatment (ReST) on speech intelligibility in children with Childhood Apraxia of Speech (CAS). The participants for this study will include 10 children (ages 48-60 months) who will undergo two types of intervention over a period of 17 weeks. An ABACA design will be used in which participants will be assessed during baseline/withdrawal phases (A) and receive the treatments during phases (B) and (C) lasting 5 weeks each. Visual analysis will be used to monitor changes in speech production accuracies across all 50 sessions. Pre- and post-intervention progress will be assessed using Children’s Speech Intelligibility Measure and the Goldman-Fristoe Test of Articulation. It is predicted that DTTC treatment will lead to better outcomes in speech intelligibility than the ReST treatment.
