Dynamic Therapy Randomised Controlled Trial

Crests of universities

The Dynamic Therapy Randomised Controlled Trial

The Dynamic Therapy Randomised Controlled Trial is a research study about improving the speech outcomes of children with moderate-severe Childhood Apraxia of Speech (CAS). The project will examine the efficacy of a treatment used to treat Apraxia – Dynamic Temporal and Tactile Cueing (DTTC or Dynamic Therapy). DTTC has been shown to be effective in smaller studies (see the research page). This is the first large study to compare DTTC to usual care in Australia and the United States.

The study is a collaboration between seven universities, two NSW Health sites, and one private practice. It will be run over 10 sites in Australia (in Sydney, Melbourne, Perth, Canberra, and Townsville,) and the United States (in Syracuse NY and Philadelphia PA).

Recruitment for this project will continue until October 2023. If you are interested in participating, please go to our participation page

This work was created on the traditional lands of a number of First Nations peoples.

The University of Sydney and the project team acknowledge the unbroken custodianship of the lands on which we work and live of the Gadigal and Wangal peoples of the Eora Nation. We acknowledge the unbroken and ongoing custodianship of all Australia’s first peoples of the land, air, and water.

The Syracuse University College of Arts and Sciences would like to acknowledge with respect the Onondaga Nation, firekeepers of the Haudenosaunee, the indigenous peoples on whose ancestral lands Syracuse University now stands.

Temple University acknowledges the Lenni-Lenape, called “Lenapehoking”, on whose traditional territory the university sits, as the original people of this land and their continuing relationship with their territory

This research project is funded by an Australian National Health and Research Council (NHMRC) Clinical Trials and Cohorts Study Grant.

The Trial is registered with the Australia and New Zealand Clinical Trials Registry (ANZCTR) and has a Universal Trials Number of U1111-1263-0335.
