  • Exploring New Treatment Methods for Childhood Apraxia of Speech

    Using Ultrasound Biofeedback, all children in the study showed improvement in their speech sound accuracy on treated sounds, and all parents reported improved speech intelligibility.

    Dr. Jonathan Preston

    A study funded by CASANA was completed by Dr. Jonathan Preston, a researcher from Haskins Laboratories (www.haskins.yale.edu) and Southern Connecticut State University. The research involved using ultrasound (the same device used to obtain images of a fetus or heart) to provide a real-time visual display of the tongue. The ultrasound transducer is held under the […]

    Understanding Childhood Apraxia of Speech

    By
    Christopher Moore, Ph.D.

    One of the most difficult challenges in understanding Children’s Apraxia of Speech (CAS) is identifying its primary characteristics. It may be that there are core features that can be observed at a number of levels in the speech production chain, including the behavioral level (what a listener might describe about a child’s speech), the acoustic […]

  • What Do Researchers Know about Genetics and CAS?

    By
    Lawrence Shriberg, Ph.D., CCC-SLP

    The primary findings on the genetics of CAS have emerged from studies of a London family (the ‘KE’ family), half of whose members have an orofacial apraxia and a reported apraxia of speech. Reviews of this widely-cited project include technical and more accessible descriptions of the mutation on the FOXP2 gene (located on chromosome 7) […]

  • What Does the Research Say Regarding Oral Motor Exercises and the Treatment of Speech Sound Disorders

    By
    Gregory L. Lof, Ph.D., CCC-SLP

    The vast majority of the legitimate research shows no changes in speech sound productions because of non-speech oral motor exercises. However, many clinicians have strong opinions about their efficacy by stating clinical anecdotes, or they will cite non-peer reviewed publications and CEU events that claim there are speech benefits of these exercises. Literature searches of […]

  • Apraxia Research Using the Apraxia-KIDS Listserv

    Preliminary Impressions

    By
    Pamela Garn-Nunn, Ph.D., CCC-SLP

    We downloaded daily postings from the Apraxia-KIDS Listserv from July 1, 1999 to December 31,1999. Anyone who posted to the Listserv was first assigned a permanent number; then all identifying information (e.g., names, location, e-mail addresses) were removed from each message and a hard copy printed out. We kept a separate, confidential master list so […]
