LED Therapy for the Treatment of Concussive Brain Injury


A double blind randomized trial of light-emitting diode (LED) therapy for patients suffering from mild traumatic brain injury (mTBI). Patients seen in the Sports Concussion Clinic with cognitive symptoms lasting for greater than 4 weeks will be randomized to either placebo therapy (controls) or treatment with LED therapy (cases). Both cases and controls would complete post-concussion symptom scales Delis-Kaplan Executive Function System (D-KEFS), and ImPACT studies on entry into the study and at weeks 3 and 6, or earlier if their symptoms resolve before the end of the 6 week period.
