Researchers at The University of South Australia are conducting experiments to investigate the effect of past illicit drug use on brain control of movement.
Participants must be 18-50 years of age.
Participants with a history of cannabis, ecstasy, and/or methamphetamine use are invited to participate.
The study involves approximately 3.5 hours in total. You will be asked to provide a urine sample for routine drug screening and to complete a series of questionnaires and neurological tests to assess hand function, speech, walking, and balance. The hand function tests will involve gripping and lifting a light weight object and the activity of your muscles will be recorded through surface electrodes stuck on the skin. A researcher will also ask you to walk and stand in front of specialist equipment. You will be asked to wear shorts and a singlet during some of the tests (the researchers will provide these) and small reflective markers will be taped to your head, trunk, and limbs. The specialised equipment will film the position of the reflective markers, not your appearance. Lastly, you will be asked to undergo a non-invasive brain ultrasound to look at brain structure.
All participants will be compensated for their time ($10 per hour).
This project has been granted ethics approval by the UniSA Human Research Ethics Committee
