Is this trial a fit for you?
✓Likely a good fit
Adults with a diagnosis of mild to moderate ME/CFS lasting more than one year, who are stable on psychological and pharmacological treatment.
✕Probably not a fit
Patients with severe ME/CFS, certain brain and cardiovascular conditions, active malignancy, pregnancy, or inability to attend all visits may not benefit.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
The trial investigates the effects of hyperbaric oxygen therapy (HBOT) in adults with mild to moderate ME/CFS. Participants will receive 60 HBOT sessions over three months, followed by three months of observation, with assessments including physical performance, cognitive tests, questionnaires, brain MRI, EEG, and blood and muscle tests. A sham treatment arm is included to compare outcomes. The study aims to determine whether HBOT can improve symptoms and functional status in ME/CFS patients. Safety monitoring and adherence checks are incorporated throughout the protocol.
Why it matters
Potential benefit: If successful, HBOT could improve energy, cognition, and physical function for people with ME/CFS.
How similar studies have gone: Previous research on HBOT for ME/CFS has shown mixed results; this trial attempts to clarify efficacy with a larger, controlled design.
