The CAMBRA Trial

Title: Copper and Magnetic bracelets for rheumatoid arthritis: a randomised double-blind placebo-controlled crossover trial.

In this study, 70 patients all wore in random sequence: a copper bracelet, a standard magnet, a weak magnet and a dummy magnet for a period of five weeks plus a wash out period of one week, i.e. the patients had a period of one week between treatments where they didn’t wear any kind of device. The trial included the taking of blood tests (C-reactive Protein and Plasma Viscosity) to measure inflammation. Analysis of treatment outcomes did not reveal any statistically significant differences (P>0.05) between the four devices in terms of their effects on pain, inflammation, physical function, disease activity, or medication use. Wearing a magnetic wrist strap or a copper bracelet did not appear to have any meaningful therapeutic effect, beyond that of a placebo, for alleviating symptoms and combating disease activity in rheumatoid arthritis. The trial has ended and the results have been published and received extensive media coverage.
