What Researchers Did
Researchers studied 50 patients with rheumatoid arthritis who received 21 sessions of hyperbaric oxygen therapy at 1.7 ATA for 40 minutes each, alongside their existing drug therapy.
What They Found
The study found that all 50 patients experienced good immediate and long-term clinical improvements. Hyperbaric oxygen therapy intensified the suppressive function of T-lymphocytes, normalized cell-bound immunity, and reduced immune complex levels in the blood.
Canadian Relevance
This study was not conducted by Canadian authors or in Canada. Rheumatoid arthritis is not currently a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
This study was conducted in 1978/1991, involved a small group of 50 patients, and lacked a control group, making it difficult to definitively attribute improvements solely to HBOT.
