Photobiomodulation: A Long-Term Study
Repeated impacts to the head can lead to difficulty thinking and managing emotions. This project explores the long-term effects of photobiomodulation (PBM) therapy, also called red-light therapy, in relation to this population.
Background
Photobiomodulation (PBM) therapy, also known as low-level light therapy and red-light therapy, involves shining red or near-infrared (NIR) light at wavelengths between 600 nm–1200 nm onto the head through an LED light.
PBM therapy has been used for decades to reduce joint inflammation, promote the healing of tissues and nerves, and treat pain. More recently, research has shown the potential benefits of PBM therapy in addressing brain disorders.
Repetitive Head Impacts and Mild Traumatic Brain Injury
Repeated bumps, blows, or hits to the head – even if they don’t result in concussion symptoms – can lead to problems such as difficulty thinking and managing emotions. Repeated impacts to the head can lead to It can also lead to loss of fine motor skills and balance.
Athletes, Service Members, Veterans, and victims of physical violence among those who are commonly affected by repetitive head impacts. There is currently no accepted Traumatic Brain Injury treatment; however, the novel approach of PBM offers some promise.
Methods
This project is collecting information from participants who are or have been exposed to repeated head impacts through sports, military service, or other means.
Participants are applying photobiomodulation therapy every other day for 20 minutes a day over 2 years.
Purpose
The information we gather will help us understand if PBM therapy aids in protecting the brain from developing issues after exposure to minor head impacts, and/or if it helps a damaged brain recover from injury due to head impacts.
Furthermore, the results of this pilot study will inform us of the potential benefits of running a clinical study in relation to PBM in the future.
