Overview
The purpose of this study is to compare effects of Photobiomodulation therapy (PBMt) to standard of care in adolescent athletes at risk for delayed recovery from subacute sports concussion, to substantiate the impact of subacute PBMt over time on functional and structural connectivity of the brain using advanced MRI sequences and to correlate the psychological and behavioral outcomes to neuroimaging findings
Eligibility

- considered at-risk for protracted recovery based on Immediate Post-concussion Assessment and Cognitive Testing (ImPACT) performance and symptom reporting on the Post-Concussion Symptom Scale (PCSS)
Exclusion Criteria:
- acute neurologic deterioration to a Glasgow Coma Scale score less than 13
- neurosurgical intervention
- abnormal CT scan
