What is the study’s purpose?

The Once Upon a Time Foundation is sponsoring research comparing treatment 2 times per week vs. 4 times per week using Dynamic Tactile and Temporal Cueing (DTTC), an evidence-based treatment method for moderate to severe CAS.

Purpose: How often per week should a child with moderate to severe CAS receive therapy?

Participant Recruitment

Community clinicians partnering with researchers are currently recruiting participants for the randomized control study. Participant Requirements include: 

2;5 to 7;0 years old

Diagnosed with moderate to severe CAS

Be available to travel to receive therapy two times a week for twelve weeks or four times a week for six weeks. Child will be randomly assigned to a treatment schedule. Map including areas where clinicians will be treating is below.

English as the primary langugage

Normal or corrected vision

Normal hearing

PRACTICE (partnering researchers and clinicians to innovate clinical excellence) clinicians and researchers partnering to conduct clinical research IN THE CLINIC. Community clinicians are across the country and will help test the effects of DTTC with 60 children with CAS when their treatment schedule is varied.

Dr. Jenya Iuzzini-Seigel

Principal Investigator

Dr. Iuzzini-Seigel is currently an assistant professor at Marquette University. Her areas of interest include assessment and treatment of childhood apraxia of speech and other communication disorders. She also has a specific interest in maximizing the clinical uptake of evidence-based protocols.

Dr. Maria Grigos

Principal Investigator

Dr. Grigos is an associate professor and chair at New York University. She is also the director of the Motor Speech Lab at NYU. Her area of interest includes the study of speech motor control and motor learning across the lifespan as well as the efficacy of motor-based intervention in childhood apraxia of speech.

Dr. Elizabeth Murray

Principal Investigator

Dr. Murray works with children from birth to adolescence as well as some adults with speech disorders at Remarkable Speech & Movement. She also works part-time teaching and conducting research at the University of Sydney. Areas of interested include investigating the treatment and diagnosis of childhood apraxia of speech as well as improving treatment for speech and language disorders. She is driven to finding a way to support families and translate the best available research into practice.

Dr. Donna Thomas

Principal Investigator

Dr. Thomas is a lecturer, clinical educator, and researcher at the University of Sydney. She has interests in assessment and treatment for children with moderate to severe speech sound disorders, tele practice, and clinical education. She is currently collaborating with several international research teams on projects investigating assessment and treatment for children with apraxia.

Dr. Shelley Velleman

Principal Investigator

Dr. Velleman has been teaching communication sciences and disorders since 1984. She is currently a professor at the University of Vermont. Her interests focus on typical and atypical speech development of children learning a variety of languages and dialects. She specializes in pediatric motor speech disorders, especially childhood apraxia of speech, including the speech of children with neurodevelopmental syndromes.

Practice Community Clinicians

30 clinicians from around the country came to Fort Worth, Texas, to be trained by the PRACTICE team for the dose frequency RCT Study.

Each clinician submitted an application to be a part of the program. They then proceeded to submit videos and write-ups to advance through another 2 rounds. Clinicians were chosen based on experience administering DTTC and their caseload of children with CAS.

Clinicians went through an intensive training to make sure that their delivery of DTTC was sufficient and met the guidelines of the study. The PRACTICE invitational training including going in-depth into the structure and application of DTTC and DEMMS assessment.
