Many SLPs (Speech-Language Pathologists) have little experience with CAS. We have FREE resources to help you.

Knowing how to perform an accurate apraxia assessment and treat CAS can be challenging, especially when the disorder is severe and there are multiple treatment programs from which to choose. Our mission is to help you do your best for children with CAS by informing you about CAS treatment resources for SLPs which include evidence-based treatments such as Dynamic Temporal and Tactile Cueing (DTTC) for treatment of moderate to severe CAS.

Important Things To Keep In Mind:

CAS is a rare motor speech disorder, occurring in only 1-2 children per 1,000.
Specialized methods are necessary to assess and treat the underlying motor

speech disorder.

Intensity matters.  Research supports treatment 3-4 times per week, especially for children with severe CAS.
With appropriate treatment, even children with severe CAS can make significant improvement and become functional verbal communicators.
There are many different methods to treat CAS, but only a few have sufficient evidence of treatment efficacy.
Follow the evidence. Learn about methods an SLP (speech-language pathologist) uses to assess and treat CAS that are supported by scientific evidence.

Evidence-Based Treatment Methods

Overview of the treatment methods used by the SLP (speech-language pathologist) for CAS with sufficient evidence to use in clinical practice.

Treatment Depends on Severity

The severity of CAS and the age of the child are important factors when selecting a treatment method.

What Clinicians are Saying

Cori R.SLP and Advanced Workshop Attendee

Spending time with Dr. Strand is like immersing yourself into a textbook regarding motor speech disorders. Dr. Strand's knowledge is wide span and provided me with the greater depth of information to guide my practice. I am very grateful for the opportunity to learn from such an expert!

Rebekah B.SLP and Advanced Workshop Attendee

DTTC advanced training has provided me with an entirely new way to think about, access and treat CAS. I have recommended it to all my SLP colleagues.

Nicole K.SLP and Advanced Workshop Attendee

The Advanced Workshop has helped me to become more confident in assessing and diagnosing Apraxia in addition to providing family education and ongoing therapy to my clients.

Kathryn K.SLP and Advanced Workshop Attendee

I have found Dr. Strand's course very helpful in my day to day clinical practice with preschool and school aged children. Her emphasis on teaching the various components of motor learning as it relates to speech production was enlightening. I also use the prompting/cueing strategies, and have had a great deal of success! I believe it is because I am now giving the children very specific feedback that enables them to change their production so it matches my model. Without a doubt, the children benefit from this multisensory approach. I am grateful to have had the opportunity to attend her course. Thank you Dr. Strand and NYU!!!

Nicole P.SLP and Advanced Workshop Attendee

I am so grateful to have had the opportunity to learn from Dr. Edythe Strand to provide DTTC to my patients with CAS. Understanding how to target specific movement gestures to improve the overall efficiency of a child's motor speech system has been instrumental in my practice. It has been particularly amazing to see the generalization of production precision and accuracy to untrained movement gestures; a true testament to how effectively this protocol works!! For example, although not directly targeted or trained, I observed the elimination of a patient's voicing errors following 1-2 months of DTTC treatment. Thank you so much!
