Pioneering technology innovations to support inclusion for people with disabilities

Technology is an enabler that has revolutionised communications and mobility options for people with cerebral palsy and other physical disabilities.

We are harnessing the power of emerging technologies through research and translation to enhance mobility, communication, and cognitive function for people with cerebral palsy, empowering them to thrive across every stage of life.

From robotics and exoskeletons to eye-gaze technology and brain-computer interfaces, many things that seemed impossible a generation ago are now a reality and already making a huge difference for people with cerebral palsy and their families. 

Our team of researchers, therapists and engineers are advancing hugely exciting projects to further unlock the future of assistive technology to make positive change by breaking down barriers to communicate, move and participate. 

Assistive technology holds the promise of an exciting future for people with cerebral palsy.

Our projects

Priority 1: Cognition

Did you know less than 1 in 3 children with cerebral palsy are able to participate in formal cognitive assessments due to communication challenges? To increase accessibility of these valuable thinking skills assessments, we have adapted a number of assessment tools that can be administered via switch and eye-gaze control technologies.

We now invite children aged between 5 and 15 years, currently using switch and eye-gaze technology, to help us test accessibility of these tools for children with motor and speech impairment.

If you or your child want to get involved, or read more information, please contact Dr Petra Karlsson at pkarlsson@cerebralpalsy.org.au or 0447 508 661

Many developmental assessments require children to show us what they know by using their hands to interact with toys. This is not accessible for some children with cerebral palsy. We are evaluating how children with CP complete a developmental assessment that has been adapted for motor and vision impairments.

Recruitment has closed.

If you or your child would like more information, please contact Dr Ingrid Honan; ingrid.honan@cerebralpalsy.org.au

Priority 2: Communication

In collaboration with the Holland Bloorview Research Institute in Canada, CPA are developing a software for recognising sound or facial movements from a user. These movements and sounds can then be used as commands for controlling a computer or communication board. Switch-App is an AI based program that can learn a person’s specific movement and keywords, so that it can be used easily by the user in a home environment.

We are a multi-stakeholder research team, including people with lived experience of cerebral palsy, clinicians, engineers and researchers conducting a research study to create a database that will be used by engineers to develop technology to improve communication for children with cerebral palsy with dysarthria. If you are interested in participating, or would like to learn more please email myvoicelibrary@cerebralpalsy.org.au.

SQUID – Standalone Quadripartite User Interface Device.This product is designed to provide people with cerebral palsy who use assistive technology for communication, and their clinicians, access to easily set up two-way telerehabilitation for remote learning and therapy sessions.

Priority 3: Mobility

CPA is collaborating with the Chinese University of Hong Kong utilising pneumatic actuators as a ‘soft exoskeleton’ to assist with different movements (such as walking or sit to stand) for children with cerebral palsy. Inflatable cuffs are place around the knees, and when inflated, assist the child to stand up and walk.

We are looking at modifying toys to better suit the needs of children with disabilities. We currently have multiple engineering honours students adapting different toys, including an accessible busy board and a touch-free instrument.

Name

The technology team

Our team is a multidisciplinary group of individuals focused on innovating and evaluating technology treatments for infants, children, youth and adults with cerebral palsy. 

The team is led by Dr Petra Karlsson and Prof Alistair McEwan from the University of Sydney. This important clinical partnership provides a valuable opportunity for interdisciplinary collaboration between people with lived experience of cerebral palsy, researchers, engineers and clinicians to facilitate evidence-informed practice with a focus of technology. 

Researcher Dr Petra Karlsson

Dr Petra Karlsson

Program Lead Technology

Petra leads a program of research that focuses on bringing allied health and biomedical engineering together, at the AHa Engineering Lab (Allied Health and Engineering). The Aha Engineering lab has a focus on innovative tech, creating multiple devices to support functioning in daily across mobility, cognition and communication investigated the use of participation to support functioning in daily activities for individuals living with severe cerebral palsy.
