Magnet Therapy

Magnet Therapy
"I know of no scientist who takes this claim seriously...It's another fad. They come and go like copper bracelets and crystals and all of these things, and this one will pass too." --Robert Park of the American Physical Society.

"Iron atoms in a magnet are crammed together in a solid state about one atom apart from one another. In your blood only four iron atoms are allocated to each hemoglobin molecule, and they are separated by distances too great to form a magnet. This is easily tested by pricking your finger and placing a drop of your blood next to a magnet. " --Michael Shermer
Magnet therapy is a type of "alternative" medicine which claims that magnetic fields have healing powers. Some claim that magnets can help broken bones heal faster, but most of the advocacy comes from those who claim that magnets relieve pain. Most of the support for these notions is in the form of testimonials and anecdotes, and can be attributed to "placebo effects and other effects accompanying their use" (Livingston 1998). The main basis for the claims is a double-blind test study, conducted at Baylor College of Medicine in Houston, which compared the effects of magnets and sham magnets on knee pain. The study involved 50 adult patients with pain related to having been infected with the polio virus when they were children. A static magnetic device or a placebo device was applied to the patient's skin for 45 minutes. The patients were asked to rate how much pain they experienced when a "trigger point was touched." The researchers reported that the 29 patients exposed to the magnetic device achieved lower pain scores than did the 21 who were exposed to the placebo device. Although this study is cited by nearly everyone selling magnets, it provides no legitimate basis for concluding that magnets offer any health-related benefit:
A less publicized experiment found that magnets did not have any effect on healing heel pain. Over a 4-week period, 19 patients wore a molded insole containing a magnetic foil, while 15 patients wore the same type of insole with no magnetic foil. In both groups, 60% reported improvement.
Despite the fact that there has been virtually no scientific testing of magnet therapy, a growing industry is producing magnetic bracelets, bands, insoles, back braces, mattresses, etc., and claiming miraculous powers for their products. The magnet market may be approaching $150 million annually (Collie). (Lerner claims that U.S. sales are near the half billion mark and that world-wide magnetic therapy is bringing in nearly twice as much.) If it works for you, you can buy them in many places.
