Impact of Photobiomodulation on Objective, Physiological Measures of Brain Function in Individuals With Post-Concussion Syndrome
Canada19 participantsStarted 2022-01-27
Plain-language summary
Photobiomodulation therapy (PBMT) uses light to influence the mitochondria of cells. PBMT of the brain enhances the metabolic capacity of neurons and stimulates anti-inflammatory, anti-apoptotic, and antioxidant responses, as well as neurogenesis and synaptogenesis. Its therapeutic role in disorders such as dementia and Parkinson's disease, as well as to treat stroke, brain trauma, and depression has gained increasing interest.
BioFlex is a form of PBMT consisting of light-emitting diodes (LEDs) and laser diodes. BioFlex utilizes red and near infrared light which penetrates tissues up to a certain tissue depth and studies have shown stimulates tissue growth and repair at the cellular level. PBMT has been proven useful for the treatment of soft tissue pain. Several studies have shown benefit in using PBMT in the treatment of certain neurological conditions, including chronic, mild traumatic brain injury (mTBI).
The purpose of this exploratory investigation, therefore, is to examine efficacy of BioFlex laser therapy on measures of brain function in patients suffering from PCS after mild-moderate, closed-head, traumatic brain injury cases.

Inclusion criteria
✓. Male or female, at least 19 years of age or older

This diagnosis should be given to the patient from a clinical practitioner. ICD-10 clinical criteria require a history of TBI and the presence of three or more of the following eight symptoms: 1) headache, 2) dizziness, 3) fatigue, 4) irritability, 5) insomnia, 6) concentration or 7) memory difficulty, and 8) intolerance of stress, emotion, or alcohol.
✓. Current pharmacologic management can remain stable throughout the protocol.
✓. Fluent in English
✓. Able to understand the informed consent form, study procedures and willing to participate in study.
Exclusion criteria
