Does magnet therapy work?

Magnetic therapy is an alternative medical practice that uses static (i.e. unmoving) magnets to alleviate pain and other health concerns. So-called therapeutic magnets are typically integrated into bracelets, rings, or shoe inserts, though therapeutic magnetic mattresses and clothing are also on the market.

Many well-conducted studies over the past three decades have shown that static magnetic devices offer no more or no less benefit than sham devices devoid of a magnet. These studies suggest that static magnetic therapy devices may not work at all beyond having a placebo effect on those who wear them.
