ASSIST: Child Apraxia Speech Treatment
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Childhood apraxia of speech (CAS) is a pediatric motor speech disorder that impairs the planning of movements needed for intelligible speech. Children with CAS often show little or slow progress in standard speech therapy. This research is a Phase 1 study that tests initial efficacy and optimal parameters of a theoretically based integral stimulation treatment called ASSIST (Apraxia of Speech Systematic Integral Stimulation Treatment). In four small randomized group design studies across three recruitment cycles (N=20 per cycle), children receive 16 hours of individual ASSIST. The studies systematically investigate the effect of treatment (ASSIST vs. no ASSIST; Study 1), the effect of complexity (complex vs. simple utterances; Study 2), the effect of lexicality (word vs. nonword targets; Study 3), and the effect of treatment intensity (Massed vs. Distributed ASSIST; Study 4). Studies 1 and 4 also systematically examine the effect of treatment on functional outcome measures, including parent ratings of intelligibility and communicative participation, and objective intelligibility measures obtained from unfamiliar listeners.
