Trial Outcomes & Findings for Hyperbaric Oxygen Therapy (HBO2) for Persistent Post-concussive Symptoms After Mild Traumatic Brain Injury (mTBI) (NCT NCT01306968)

NCT ID: NCT01306968

Last Updated: 2014-09-05

Results Overview

The Rivermead Post-Concussion Symptom Questionnaire (RPQ)/RPQ-3 was created to measure the severity of post-concussion symptoms following traumatic brain injury. The scale compares any current symptoms to pre-injury levels to account for potential symptom exacerbation due to the TBI. The RPQ is the most commonly used clinical outcome measure for mild TBI research because it is simple and reflects psychosocial function. The RPQ is intended to measure the presence and severity of 16 of the most commonly reported post-concussion symptoms found in the literature.

Measure
PTSD With no History of TBI
Non-randomized - Subjects who have been diagnosed with PTSD but have no diagnosed or suspected brain injuries. This group did not receive hyperbaric oxygen.
Standard TBI Care
Routine post-concussive symptoms (PCS) care as practiced within Departments of Defense (DoD)
HBO2 Group
Routine PCS care supplemented with hyperbaric oxygen (HBO2) at the dose of 1.5 ATA for 60 minutes administered over 40 sessions given daily Monday through Friday hyperbaric oxygen: The chamber will be compressed with air to 1.5 atm abs. Once the chamber is compressed to 1.5 atm abs, the subjects will don a hood and breathe 100% oxygen. Hoods will be supplied with oxygen with flows of at least 30 liters per minute and overboard dumping of excess gas. Each subject will complete 40 sessions. The duration of the hyperbaric oxygen exposures will be 60 minutes (±2 minutes), timed from when the chamber hatch or door closes, and ending when the chamber hatch or door opens ("door-to-door" time equals 60 minutes). The total intervention exposure time is 50 minutes (±2 minutes). The interval to compress to the intervention pressure (1.5 atm abs) and will be 5 minutes (±1 minute). The interval to decompress from the study pressure will be 5 minutes (±1 minute).
Sham Group
Routine PCS care supplemented with an otherwise identical sham hyperbaric air exposure at 1.2 atmospheres absolute (ATA) sham hyperbaric air: A pressure of 1.2 atm abs will provide an equivalent inhaled oxygen concentration of 25%. The duration of the sham exposures will be 60 minutes (±2 minutes). Each subject will complete 40 sessions.
