Concussions are a prevalent topic in medicine. Concussion symptoms include headaches, dizziness, nausea, neuropsychiatric symptoms, and cognitive impairments, the persistence of which is referred to as postconcussion syndrome. Hyperbaric oxygen therapy (HBOT) has been proposed and evaluated as an additional treatment of these symptoms. HBOT is an innovative approach that has been considered by many but has received both criticism and acceptance.
Is HBOT an effective means of reducing symptoms for individuals suffering from postconcussion syndrome (persistence of symptoms for >3 mo)?
The literature was searched for studies that were relevant to the clinical question. Literature provided 5 level 1 studies that were relevant enough to be considered.
Based on the research that is available, the authors conclude that there is more evidence to refute the use of HBOT for postconcussion syndrome than to support it.
Four studies disprove the use of HBOT; 1 study supported the use of HBOT. These 5 studies are the same level of evidence (level 1) and provide significant findings in their studies. The strength of this recommendation is a B according to the Centre for Evidence-Based Medicine.
