Would you pay out-of-pocket for a wellness device not approved by the FDA to treat health?

A University of Utah study published in the Journal of Neurotrauma indicates that red light therapy may effectively reduce brain inflammation in football players. The research highlights the potential for photobiomodulation to assist athletes dealing with neurological symptoms.

Why it matters

The study provides insight into potential non-invasive methods for addressing neurological damage in contact sports athletes. It highlights ongoing efforts to understand how light-based therapies can stimulate repair processes in the brain.

The study examined the use of red and near-infrared light through a Vielight device to stimulate tissue repair. While the device costs approximately $2,000, it remains unapproved by the FDA for brain injury and is not covered by insurance.

The players

Rico Petrini

A former football player who sustained 15,000 sub-concussive hits and 25 concussions during his career.

The institution that conducted the study on photobiomodulation and its effects on brain inflammation.

The details

The device delivers light through the skull and nose to release nitric oxide, which relaxes blood vessels and improves circulation. By releasing growth factors, the therapy aims to boost cellular energy and aid in the repair of damaged brain tissues.

The Big Picture

This research contributes to the growing body of literature in the Journal of Neurotrauma investigating novel recovery paths for brain injuries. It marks a shift toward examining light-based interventions as a complement to traditional neurological treatments.

The Vielight device is currently classified as a general wellness product, meaning it is not covered by health insurance and carries a $2,000 price tag. Users should note that the device lacks FDA approval for treating specific traumatic brain injuries.

The takeaway

Patients interested in red light therapy should consult with medical professionals, as these devices currently lack clinical validation for brain trauma. Prospective users must also consider the significant out-of-pocket costs associated with non-FDA approved wellness products.
