Copper bracelets and magnetic wrist straps flunk arthritis test

Posted 22 September 2013

A well designed study has found that wearing a magnetic wrist strap or copper bracelet had no practical value for patients with rheumatoid arthritis. The study involved 70 patients who were randomly assigned in various sequences to wear a standard (1502 to 2365 gauss) magnetic wrist strap and three control devices: a demagnetised (<20 gauss) wrist strap, an attenuated (250 to 350 gauss) magnetic wrist strap, and a copper bracelet. No differences among the groups were found for pain, inflammation, disease activity, disability, or medication requirement patterns.
