Effectiveness of Radon Spa Therapy in Multimodal Rehabilitative Treatment of Rheumatoid Arthritis

The study aimed to investigate effects of radon (plus CO2) baths on RA in contrast to artificial CO2 baths in RA rehabilitation. 134 patients of an in-patient rehabilitative programme were randomly assigned to the groups. Outcomes were limitations in occupational context/ daily living (main outcome), pain, medication, etc. measured before start, after end of treatment, and up to a year thereafter. Superiority of radon treatment was found regarding reduced limitations in daily living until 12 months after end of treatment. Steroid consumption and NSAIDs were significantly reduced.
