I use Dynamic Temporal and Tactile Cueing (DTTC), which is guided by the principles of motor learning, in order to efficiently and successfully improve the child's movement gestures for speech production. Treatment initially requires several sessions per week and our goal is to maximize the number of productions of target words/ phrases during each session. Therapy is constantly changing as we reduce cueing over time and increase the number and complexity of target words/ phrases as each is mastered. The end goal is the child's generalization of accurate movement gestures for speech, so that he or she can be highly intelligible outside of speech therapy sessions.
I recommend that parents look at the Apraxia Kids website as a great source of information. When fellow SLPs express uncertainty when dealing a child suspected of having CAS, I always recommend that they go to the Apraxia-Kids website and look out for continuing education opportunities involving Apraxia Kids.
I provide education to parents regarding what CAS is and how this diagnosis affects our therapy planning. We discuss our goals including my rationales for therapeutic choices and parents provide input as to which target words may be most functional for the child. I talk to parents about how they can help their child best.
I have typically used sign language as an aid for verbal communication while addressing CAS in therapy.
