What Researchers Did
Researchers conducted a randomised controlled trial with 50 subjects to assess cognitive and PTSD symptom changes in traumatic brain injury patients receiving hyperbaric oxygen therapy (2.4 atm abs) versus a sham treatment (1.3 atm abs).
What They Found
Overall, no statistically significant differences were found between the hyperbaric oxygen and sham groups in cognitive scores or PTSD symptoms, though both groups showed improvement. However, subgroup analyses revealed improvements in the treatment group compared to sham for specific factors like concussion history, visual memory, and processing.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation of this study is the lack of overall statistically significant differences between groups, with positive findings primarily observed in subgroup analyses which require further validation.
