What this Trial Is About
Childhood apraxia of speech (CAS) is a complex, multivariate speech motor disorder characterized by difficulty planning and programming movements of the speech articulators (ASHA, 2007; Ayres, 1985; Campbell et al., 2007; Davis et al., 1998; Forrest, 2003; Shriberg et al., 1997). Despite the profound impact that CAS can have on a child's ability to communicate, little data are available to direct treatment in this challenging population. Historically, children with CAS have been treated with articulation and phonologically based approaches with limited effectiveness in improving speech, as shown by very slow treatment progress and poor generalization of skills to new contexts. With the emerging data regarding speech motor deficits in CAS, there is a critical need to test treatments that directly refine speech movements using methods that quantify speech motor control. This research is a Randomized Control Trial designed to examine the outcomes of a non-traditional, motor-based approach, Dynamic Temporal and Tactile Cuing (DTTC), to improve speech production in children with CAS. The overall objectives of this research are (i) to test the efficacy of DTTC in young children with CAS (N=72) by examining the impact of DTTC on treated words, generalization to untreated words and post-treatment maintenance, and (ii) to examine how individual patterns of speech motor variability impact response to DTTC.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Diagnosis of childhood apraxia of speech (CAS) confirmed by two speech language pathologists based on specific core features and additional characteristics
- Age between 2.5 and 7.11 years
- Normal structure of the oral-peripheral mechanism
- Passing a hearing screening at 20 dB SPL at 500, 1000, 2000, and 4000 Hz
- No prior treatment with Dynamic Temporal and Tactile Cuing (DTTC)
You will not qualify if you...
- History of neurological disorders (e.g., cerebral palsy), developmental disorders (e.g., autism spectrum disorder), or genetic disorders (e.g., Down syndrome)
- Presence of dysarthria, even if CAS criteria are met
- Presence of fluency disorders, even if CAS criteria are met
- Conductive or sensorineural hearing loss, even if CAS criteria are met
- Previous treatment with Dynamic Temporal and Tactile Cuing (DTTC)
