The contraction of muscles can be detected by a system called mechanomyogram (MMG). This study aims to investigate ways in which information from unwanted muscle contractions during a specific line drawing task can enhance detection of intention. We will recruit a control group of typically developing children as well as a group of children with dyskinetic cerebral palsy. An MMG signal of main arm muscles will be recorded during the line drawing task. The signal recorded will then be used to create a prediction model of the movement performed by the participant. This research will eventually allow children and youth with disabilities to use their intentional muscle contractions to communicate and interact with their environment, even in the presence of excessive undesired muscle contractions.

For this study we are looking into studying muscle activation during a drawing task. We will be comparing a control group of typically developing children and a group of children with dyskinetic cerebral palsy. A non-invasive system called Mechanomyography (MMG) will be used to collect the signals created by muscles while performing the task.
Only one 1 hour session
Non-invasive sensors will be superficially attached to 8 different parts along one arm
The task is to draw horizontal and vertical lines on a tablet
Measurements of muscles vibrations will be recorded with the MMG system.
Participants will receive a small token of appreciation, to thank them for their time.
Recruitment for this study has closed.
