Abstract

Purpose Given the fact that neuroimaging studies are currently not used routinely in the evaluation of concussions in the clinical setting, the diagnosis and management of concussion has centered around subjective symptom reports, clinical and neurocognitive examinations. Functional near-infrared spectroscopy (fNIRS), a noninvasive and portable neuroimaging modality that detects changes in blood oxygenation related to human brain function, is a promising tool to address this gap in the clinical evaluation of concussion. While fNIRS has recently demonstrated that adults with a concussion show reduced brain activation on neurocognitive tests compared to healthy age-matched controls, it has not yet been assessed with other clinical tasks or in the pediatric setting. Thus, we sought to determine the utility of fNIRS to detect and differentiate cortical brain activity among the suite of vestibular oculomotor tests used in a standard clinical evaluation of pediatric concussion. Methods We conducted baseline testing of nine athletes, ages...
