简要总结
The goal of this research is to serve as a demonstration project to determine the tolerability of individuals with persistent post-concussive symptoms from combat-related mild TBI (traumatic brain injury), identify dose-finding for HBO2 (Hyperbaric Oxygen) therapy, and determine the efficacy of HBO2 therapy.
详细描述
Persistent post-concussive symptoms from mild traumatic brain injury are a severe issue facing the readiness, retention and quality of life of Department of Defense(DoD) service members and Veterans. The inadequacy of established treatment regimens and evidence-based science in post-concussive symptoms (PCS)/MTBI is forcing a closer look at non-conventional treatments of this condition. Hyperbaric oxygen (HBO2) is a potent intervention with demonstrated efficacy in dive-related injuries, soft tissue healing, and carbon monoxide poisoning.
This study is prospective, randomized, double-blinded and controlled. A total of 60 subjects will be randomly assigned to one of three treatment arms of the study: 20 subjects into the 1.5 atm abs oxygen equivalent HBO2 treatment, 20 subjects into the 2.0 atm abs oxygen equivalent HBO2 treatment and 20 subjects into the sham treatment (a placebo exposure equivalent to breathing atmospheric air). The protocol utilizes a pre- and post-treatment comprehensive performance battery that will allow for meaningful clinical outcomes and a broad understanding of the effects of the treatment. This project represents a collaboration between the Department of Defense (DoD), the Richmond Veterans Administration Medical Center (VAMC) and Virginia Commonwealth University. Service members will be recruited from military bases/treatment facilities (MTF), receive hyperbaric oxygen at existing DoD hyperbaric chambers and be evaluated by the established Virginia Commonwealth University-Center for Rehabilitation Sciences and Engineering (CERSE), a collaborative research center co-located at the Richmond VAMC and VCU.
