Concussion Recovery and Wellness Modalities

Why it might help

Transcranial near-infrared light is proposed to influence mitochondrial energy production, cerebral blood flow, and inflammatory signaling, but a full-body red-light bed does not reproduce the dose or delivery geometry of a head-targeted device.

What the research shows

In a randomized, double-blind, placebo-controlled trial, 48 participants age 11 or older with persistent post-concussion symptoms completed six weeks of transcranial photobiomodulation or placebo, delivered as two 10-minute sessions three times weekly. After adjustment for prior concussions and multiple comparisons, there were no significant between-group differences at three or six weeks. A separate publication described improvement in one person after eight weeks of home transcranial treatment, but a single case cannot establish efficacy.

Why it might help

Hyperbaric oxygen increases dissolved oxygen under pressure and is proposed to influence perfusion and neuroplasticity, but pressure itself may produce nonspecific effects and study sham conditions may not be physiologically inert.

What the research shows

A multicenter, double-blind, sham-controlled randomized trial enrolled 72 military service members with symptoms at least four months after mild traumatic brain injury and compared 40 sessions at 1.5 ATA, 40 sham sessions with room air at 1.2 ATA, and routine care alone. Both chamber groups improved on some symptom measures, but hyperbaric oxygen did not outperform sham. A systematic review of post-concussion treatments found five high-grade randomized trials with contradictory results, including two positive and three negative, and concluded that the evidence did not support hyperbaric oxygen for persistent symptoms at that time.
