Is electromagnetic field treatment (EFT) effective for the treatment of osteoarthritis (OA)?
The quality of the evidence of all included trials was moderate or low. The protocols for pulsed electrical stimulation or pulsed EFT device setting and application varied widely between studies, as did outcome measures.
EFT is currently used by physiotherapists. It is thought it may promote growth and repair of bone and cartilage based on principles of physics, including Wolff’s Law, the piezoelectric effect and the concept of streaming potentials.
