Pulse electromagnetic field stimulation (PEMF) is a therapy that can be used to promote bone healing and fusion. The therapy uses short bursts of low-level electromagnetic fields and can relieve continuing leg or back pain after surgery, fibromyalgia, and osteoarthritis. The extent of pain relief achieved with electrotherapy varies widely, depending on the person and injury.

PEMF therapy can be accessed through a professional, such as a physical therapist or chiropractor. PEMF devices can be purchased for at-home use. Most devices on the market are FDA-approved wellness devices, although it is recommended to speak with a doctor before use.
