![]() ![]() Data will be collected in weeks 1, 4, and 7 (T1, T2, and T3, respectively). ![]() In all three treatment studies, 20 children will be randomly assigned to conditions and will receive 16 hours of ASSIST in two-week blocks (weeks 2-3 and/or 5-6). This research includes three small-scale group treatment studies (Studies 1-3), conducted during summer to minimize confounds from concurrent treatment provided at school. In particular, for each of the three studies, the investigators will examine changes on the following outcome measures:Īim 3a: Parent-rated measures of intelligibility and communicative participation.Īim 3b: Objective measures of intelligibility based on transcriptions by unfamiliar listeners. Specific Aim 3: To determine changes on functional outcome measures following ASSIST treatment. Massed practice may enhance learning through neuroplasticity principles, but motor learning principles predict greater learning for distributed practice. Real words may enhance motivation through functional relevance, but nonwords may facilitate transfer through a focus on underlying speech motor skills rather than existing lexical or speech motor representations.Īim 2c: INTENSITY: massed vs. Simple targets may enhance motivation through greater success during treatment, but more complex targets may facilitate greater transfer.Īim 2b: LEXICALITY: real word vs. In three studies, children (N=20 each) will be randomly assigned to condition, to address three critical treatment parameters:Īim 2a: COMPLEXITY: simple vs. Specific Aim 2: To determine the optimal parameters of ASSIST for children with CAS. The central hypothesis is that ASSIST enhances speech motor skill, and predicts greater improvements after 2 weeks (16 hours) for the treatment group than for the control group (who have not yet received treatment). Forty children (combined across two studies) will be randomly assigned to a treatment or a control group (who will receive the treatment). Specific Aim 1: To test the initial efficacy of intensive ASSIST for children with CAS, by examining short-term improvements on the primary outcome measure of speech accuracy. ![]() The overall objective of this research is to test the initial efficacy of ASSIST and determine its optimal parameters. ![]() This research involves a hypothesis-driven series of Phase 1 studies using comparative group designs to investigate a new integral stimulation treatment program for children with CAS, called ASSIST (Apraxia of Speech Systematic Integral Stimulation Treatment). Each study also systematically examines the effect of treatment on functional outcome measures, including parent ratings of intelligibility and communicative participation, and objective intelligibility measures obtained from unfamiliar listeners. complex target) and lexicality (words vs. 4 weeks) and two critical aspects of target selection: complexity (simple vs. The three studies systematically investigate treatment intensity (2 vs. In three small randomized group design studies, children (N=20 per study) receive 16 hours of individual ASSIST. 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). Children with CAS often show little or slow progress in standard speech therapy. Why Should I Register and Submit Results?Ĭhildhood apraxia of speech (CAS) is a pediatric motor speech disorder that impairs the planning of movements needed for intelligible speech. ![]()
