Introduction to Childhood Apraxia of Speech (CAS)

FREE online video course taught by Dr. Edythe Strand provides an overview of CAS.

Description of the Online Video

This video provides an introduction to childhood apraxia of speech (CAS) and describes how it differs from other speech sound disorders, such as a phonological disorder. The video reviews evidence-based assessment and treatment methods including videos that demonstrate different aspects of treatment supported by research. This is an excellent video for speech-language pathologists (SLPs), SLP students, parents, caregivers and family members who want to understand the general principals of assessment and treatment of CAS.

Target Audience: This course is designed for speech-language pathologists and parents/caregivers seeking introductory information about evidence-based diagnosis and treatment of CAS.

Prerequisites: There are no prerequisites for this course.

Course Availability: This course will be available for ASHA CEUs starting April 1, 2021 until March 31, 2023.

This course was recorded in June 2019 and is provided by the Once Upon a Time Foundation.

Online Video Course Objectives

As a result of this video presentation, the participant will be able to:

  1. describe three characteristics of CAS that distinguish it from other speech sound disorders and aid in differential diagnosis,
  2. describe three ways that treatment of CAS differs from more common phonological-based speech sound disorders,
  3. describe two benefits of using a dynamic motor speech examination in assessment of CAS,
  4. describe two evidence-based treatment methods for CAS, and
  5. describe three treatment techniques/strategies for CAS.

About the Instructor

Edythe Strand, PhD, CCC-SLP
Dr. Strand is an emeritus professor in the Mayo College of Medicine and former Head of the Division of Speech Pathology, Department of Neurology at the Mayo Clinic, in Rochester, Minnesota. She is internationally recognized for her expertise in childhood apraxia of speech. Dr. Strand’s research focused on developmental, acquired and progressive apraxia of speech, and issues related to intelligibility and comprehensibility in degenerative dysarthria. She has a long history of clinical experience, including the public schools, private practice, and hospital and clinic settings. Dr. Strand developed The Dynamic Temporal and Tactile Cueing (DTTC) approach for CAS treatment, which was found to be one of two motor-based treatment approaches with sufficient evidence for clinical use (Murray, et. al., 2014). Dr. Strand’s publications include many articles and book chapters related to motor speech disorders. She is the co-author of the books: Management of Speech and Swallowing in Degenerative Disease; Clinical Management of Motor Speech Disorders in Children and Adults; and is co-editor of the book, Clinical Management of Motor Speech Disorders in Children.
