Most complementary therapies used by people with rheumatoid arthritis are not effective, a study has suggested.
The Arthritis Research Campaign looked at the scientific evidence available for 40 treatments. Two thirds of treatments for rheumatoid arthritis and a fifth of treatments for osteoarthritis were found to be ineffective by the researchers. The Arthritis Research Campaign said it wanted people who used the therapies to know what evidence was available.
Rheumatoid arthritis is caused by inflammation of the lining (synovium) of the joints.
Osteoarthritis is caused by the breakdown of protective tissue called cartilage in the joints. Inflammation results when the unprotected bones of the joint begin to rub together. It most commonly affects the joints of the fingers, knees, hips, and spine.
In total, 60% of people with arthritis are thought to use some form of complementary medicine.
