Study information
Scientific title
Acronym
CAMBRA (Copper And Magnetic Bracelets for Rheumatoid Arthritis)
Study hypothesis
The proposed trial will investigate the therapeutic effectiveness of commercially available magnet wrist straps and copper bracelets when used as an adjunct to practitioner led management of pain and inflammation in Rheumatoid Arthritis (RA). Possible effects on other major health outcomes will also be considered. This addresses a need for rigorous scientific evidence on the subject.
