Autonomic nervous system response to stress in children after mild traumatic brain injury (mTBI) compared to non-injured controls: a pilot study

Actively Recruiting: Concussion


We want to study how the body changes in response to stress in children recovering from a concussion. Stress can sometimes cause changes in heart rate, breathing, and skin temperature.  Some children after a concussion have symptoms such as headache that are triggered or worsened by stress.  In the future it may help us better tailor treatments to help these children manage stressful situations.

Who can participate

Boys or girls aged 12-18 with a diagnosis of concussion within the last six months and persistent symptoms after the concussion are eligible to participate.

What's Involved

Study participants will attend one research session (taking approximately 45 minutes) in the Bloorview Research Institute, where we will measure physiological signals including heart rate, respiration, and skin temperature. During this session, participants will complete a stress test.

Participants will receive a small token of appreciation, [e.g. $25 gift card] to thank them for their time. Participants will also receive $10 to cover parking costs.
