Central mechanism behind neuromuscular control of the shoulder
The study aims to offer new insight into the role of the brain in muscular control of the shoulder.
The objectives are to test the control of shoulder muscles during multiple contraction tasks, and to explore how the brain is involved in muscular control.
The findings can provide a stepping-stone for future studies to better understand mechanisms involved in shoulder pain and ultimately improve clinical management.
The experiment is one-off. It includes the use of Transcranial Magnetic Stimulation at the head and Electromyography at the shoulder muscles.
The participant will be asked to perform multiple tasks including muscle contractions to maximal effort and static holds at low intensities.
Breaks will be incorporated as needed to avoid/minimize fatigue.
Eligibility
We are looking for healthy adults.
Exclusion criteria:
- Current pregnancy
- The presence of shoulder and/or bodily pain
- The presence of shoulder injuries
- The presence of major neurological, cardiovascular or respiratory diseases, brain injuries (such as vascular, traumatic tumoral, infectious, or metabolic lesion of the brain)
- Any history of seizures or epilepsy or unexplained fainting, and any implanted electrodes in the brain or pacemaker electrodes for the heart
Participant benefits
Participants will receive $50 reimbursement after attending the experiment session.
