Magnetic therapy is used most often for pain, usually of the joints and muscles. Magnets have also been applied to relieve post-surgery pain. Some advocates suggest that magnets can reduce stress, as well as relieve insomnia and treat migraine. Others even claim that magnetic therapy can fight infection and improve central nervous system disorders, such as seizures. While research has shown that magnet therapy can indeed relieve pain, there is little solid evidence validating it for other ailments.
In a study published in the American Journal of Pain Management (http://www.ajpmonline.com/) in 1999, magnetic foot insoles were shown to be effective in reducing foot pain in those with diabetes.Still, the findings are preliminary. And many other studies have shown that magnets do not provide effective therapy. A new, experimental area of research involves transcranial magnetic stimulation (TMS), a technique that permits stimulation of the brain's surface using strong magnetic fields. Most research using TMS has concentrated on it as a treatment for severe depression. However, the therapy may eventually prove useful for other illnesses, such as epilepsy and schizophrenia.
