Magnet therapy (an energy therapy) uses static magnetic fields or electromagnetic fields. Practitioners place magnets on the body to reduce pain or enhance healing. Magnets may or may not be connected to an electric charge. (See also Overview of Integrative, Complementary, and Alternative Medicine.)
Magnets, in particular, are used in treatment for various musculoskeletal conditions and pain. Magnets are marketed in clothing, jewelry, and mattresses to relieve pain.
Static magnet therapy remains scientifically unproven, especially for pain relief, which is one of the most common applications. Well-designed studies of static magnets indicate that they are not effective for chronic pain, osteoarthritis, and rheumatoid arthritis.
