The Dynamic Therapy RCT is a clinical trial that will examine the efficacy of a treatment used to treat Childhood Apraxia of Speech – Dynamic Temporal and Tactile Cueing (DTTC or Dynamic Therapy). This research project aims to improve the speech outcomes of children with severe Childhood Apraxia of Speech (CAS).

Dynamic Tactile and Temporal Cueing

Dynamic Therapy is a treatment developed to treat CAS known in other studies as Dynamic Temporal and Tactile Cueing (DTTC). The therapy targets a core set of meaningful words which contain sounds that the child can already produce (e.g., “Hi daddy”) and sounds which are emerging. Within a session, the Speech Pathologist uses a range of cues to help the child produce a word. These cues include tactile cues and verbal prompts for children to “look at me, listen to me, say what I say”.

DTTC has been shown to be effective in small scale studies with children who have moderate – profound speech impairments caused by childhood apraxia of speech.  This is the first large scale randomised control trial to evaluate DTTC compared with usual care.

Who can participate?

We are looking for children who:

  • Have a diagnosis of Childhood Apraxia of Speech
  • Are 3 to 7 years and 11 months at their assessment with us
  • Have a speech impairment in the moderate-severe range
  • Have normal hearing and vision with or without corrective devices (e.g., glasses, hearing aids)
  • Speak English at home as their primary language

Children who participate will be randomized to either receive DTTC from the research team or keep going with their usual care. We will also ask parents to complete surveys about their usual care and speech pathology experiences.

We will also ask if we can contact your treating speech pathologist for some information about the treatment your child is receiving.
