| Are magnets and magnetic therapy devices helpful for pain? The answer to this question differs for different types of magnets. For static magnetsâthe type often incorporated into wristbands, mats, pillows, and bed pads, thereâs no good evidence of a benefit for any form of pain.  On the other hand, there is evidence that electromagnetic therapies, such as pulsed electromagnetic field therapy (also called PEMF), may be helpful for some types of pain, such as low-back pain and pain from osteoarthritis of the knee or hands.  Read our updated fact sheet, âMagnets for Pain: What You Need To Knowâ to find out more. |
