Complementary and alternative medicine in rheumatology.

Complementary and alternative medicine (CAM) has become an important subject for rheumatologists. This article is an attempt to provide an introduction to this subject. It will provide definitions of, and define the prevalence of, CAM. The emphasis of the article is on evaluating the efficacy of CAM treatment modalities. This is achieved by referring to systematic reviews of clinical trials of acupuncture for low back pain, osteo-arthritis, fibromyalgia, inflammatory rheumatoid disease and neck pain. Further areas addressed in this way are herbal remedies, fish oil and glucosamine. Moreover, massage therapy and spinal manipulation for back pain are discussed. The final sections of this review deal with the safety and cost of CAM. It is concluded that, in view of the popularity of CAM with rheumatological patients, rigorous research into CAM is the best way forward.
