What Researchers Did
Researchers conducted a double-blind randomised controlled trial involving 49 patients with chronic multiple sclerosis to evaluate the effect of hyperbaric oxygen therapy over four weeks.
What They Found
The study found no objective improvement in clinical, neurophysiological, or immunological parameters across all three groups, including the 49 patients receiving hyperbaric oxygen or control. While some patients subjectively reported feeling better, this was equally observed in both the treated groups and the control group, indicating no specific benefit from hyperbaric oxygen.
Canadian Relevance
This study was conducted in France and has no direct Canadian connection.
Study Limitations
The study's relatively small sample size of 49 patients and its specific treatment protocols may limit the generalizability of its findings.
