What Researchers Did
Researchers retrospectively analyzed medical records of 20 traumatic brain injury patients who received hyperbaric oxygen therapy plus standard care, comparing them to 20 matched patients who received standard care alone.
What They Found
Patients receiving hyperbaric oxygen therapy showed maximum improvement on the Disability Rating Scale, particularly those initially in a vegetative state (scores 22-24). The percentage of patients in the test group in this severe state decreased from 45% to 5% after treatment.
Canadian Relevance
There is no direct Canadian connection mentioned in this study, as it was conducted at a tertiary care center outside of Canada.
Study Limitations
The study's retrospective design and small sample size of 20 patients per group limit the generalizability and strength of its conclusions.
