The Center for Disease Control estimates that between 1.4 and 1.8 million civilians in the US sustain a traumatic brain injury (TBI) each year. The objectives of the study will be evaluated in a civilian population which has sustained a mild Traumatic Brain Injury (mTBI). Research has found that the total cost due to headache in the US workforce is $20 billion per year, most of which is in the form of reduce productivity while at work. For patients with TBI who are already struggling with cognitive and health challenges in an effort to be productive, it seems reasonable to suspect that chronic PTH may slow rehabilitation efforts and successful re-entry into the work force and societal responsibility.
