The study will test two modifications to speech therapy for 40 school-age children with childhood apraxia of speech to determine how to improve treatment outcomes. The study will compare treatment that includes real-time visual feedback of the tongue during speech using ultrasound vs traditional therapy that does not include ultrasound visual feedback. Additionally, some children will be treated with a traditional schedule of 2 sessions per week, whereas others will be provided with treatment that begins with intensive training (10 hours of therapy in one week) and progresses to a more distributed treatment schedule.
Childhood apraxia of speech is a developmental speech sound disorder that may lead to persisting speech errors, often despite years of treatment. Such impairments may lead to social, academic, and vocational limitations. Thus, there is a need to explore alternate treatment approaches. This study will explore how to improve speech sound production in school-age children with CAS by modifying a standard speech therapy program. Two adaptations to speech therapy will be tested in a 2 x 2 randomized group design.
In Aim 1, a standard treatment schedule of 2 one-hour sessions per week will be compared against a treatment sequence beginning with an intensive therapy schedule (10 hrs of treatment in one week), which will then transition to a more distributed practice schedule. This treatment modification is intended to minimize erred practice between training sessions in the early stages of learning, then foster generalization through increased time between practice sessions.
In Aim 2, a standard treatment that includes only verbal feedback to the client during speech practice will be compared against a treatment sequence that initially includes real-time ultrasound visual feedback of the tongue during speech, which will be faded over the course of treatment. Ultrasound visual feedback is designed to train articulatory movements. It may enhance children's understanding of the articulatory goals of speech movement patterns by comparing executed tongue movements with intended movements. Prior case reports and single subject experimental designs have shown that speech sound production may be enhanced by including ultrasound visual feedback, although no prior randomized group studies have been conducted.
Beside these modifications, the other aspects of treatment will be held constant. Outcomes will be evaluated by tracking changes in percent consonants correct from a large speech sample, scored by individuals who are blind to treatment status. The four groups will be compared to determine the extent to which speech sound therapy can be enhanced through a treatment sequence that begins with intensive practice and/or with ultrasound visual feedback.

Treatment for individuals with speech defects and disorders that involves counseling and use of various exercises and aids to help the development of new speech habits.
An aphasia characterized by impairment of expressive language (speech, writing, signs) and relative preservation of receptive language abilities (i.e., comprehension). This condition is caused by lesions of the motor association cortex in the frontal lobe (Broca's area and adjacent cortical and white matter regions). The deficits range from almost complete muteness to a reduction in the fluency and rate of speech. CEREBROVASCULAR ACCIDENTS (in particular INFARCTION, MIDDLE CEREBRAL ARTERY) are a relatively common cause of this condition. (From Adams et al., Principles of Neurology, 6th ed, pp478-9)
