Testing of a Novel Optical Imaging Device for Concussion Diagnosis and Management


Concussion and brain injury are recognized as a major health issue for Canadians. This
problem may be especially severe in pediatric populations where brain injury could have life
long implications and since children are more likely than adults to have persistent symptoms.
We need better tools to quantify concussion. This method, functional near-infrared
spectroscopy (fNIRS) detects changes in hemoglobin oxygenation as a marker of brain
activity. we will use fNIRS to study functional changes in the brain of subjects following concussion.
