This systematic review investigates the effects of different treatment approaches for childhood apraxia of speech (CAS) (e.g., motor, linguistic/phonological, augmentative and alternative communication) on treatment, maintence, and generalization outcomes in children, younger than 18 years of age, with suspected or diagnosed CAS.

<div>The three treatments with demonstrated treatment effects (i.e., Integral Stimulation/Dynamic Temporal and Tactile Cueing, Rapid Syllable Transition, and Integrated Phonological Awareness Intervention) "are best suited to interim clinical use, with sessions at least twice a week and dose above 60 trials per session" (p. 501).</div>
<div>Interventions with suggestive evidence include augmentative and alternative communication (AAC), some combined cueing/motor approaches, rate control, and some combined linguistic/motor treatments.</div>
<div>The following treatments were indicated to have predominant evidence supporting positive treatment and generalization effects:</div>
<ul>
<li>Integral Stimulation/Dynamic Temporal and Tactile Cueing (DTTC);</li>
<li>Rapid Syllable Transition Treatment (ReST); and </li>
<li>Integrated Phonological Awareness Intervention. </li>
</ul>
<div>The included studies indicated the following findings:</div>
<ul>
<li>Dynamic Temporal and Tactile Cueing (DTTC) "appears to work better for clients with more severe [childhood apraxia of speech] CAS; </li>
<li>Integrated Phonological Awareness Intervention appears to work better for children 4-7 years of age with mild to severe CAS; and </li>
<li>[Rapid Syllable Transition Treatment] ReST appears to work better for children 7-10 years of age with mild-to-moderate CAS" (p. 501).</li>
</ul>
<div>"Intensive treatment delivery in impairment-based intervention appears crucial for obtaining positive treatment outcomes" (p. 501).</div>
