We often see people walking around with copper bracelets on their wrist. The bracelets are supposed to ease muscle aches and arthritis pains - but do they actually work?
Apparently, they are no better than a placebo, or sugar pill - and nor are magnetic wrist straps, which are also worn to ease musculoskeletal pains, a new study has discovered.
The devices were tested on 45 osteoarthritis sufferers, but the researchers couldn't detect any real difference between them, or when measured against a 'dummy' magnetic strap, or non-copper bracelet.
