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
. Diagnosis of persistent post-concussional syndrome after ≥3 months of traumatic brain injury, based on the ICD-10 criteria. 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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
