PEMF, or Pulsed Electromagnetic Field therapy, is a non-invasive method of treating a variety of conditions. The practice was approved by the FDA in 1979 to stimulate growth of bone. In 1991 it was approved for use in the treatment of post-operative edema and pain in superficial soft tissue. In 2004, the FDA approved PEMF for patients at risk for non-fusion, as an adjunct to cervical fusion surgery.
PEMF has been found to be effective and safe, and is often used in patients with long bone fractures. Electromagnetic and magnetic fields are recognized as very promising for a variety of health problems.
