ABSTRACT
Pulsed electromagnetic field (PEMF) therapy has been shown to contain a wide range of spectral components allowing for potential coupling to a variety of possible biochemical signaling pathways. The possibility of treatment using electromagnetic fields for various disorders has therefore drawn interest in part due to the ability to noninvasively induce an electric current in the target tissue. PEMF has been clinically investigated for the adjunctive treatment of rotator cuff repair showing early reduction in pain and increased range of motion. While in-vitro research has shown that PEMF had a positive effect on tenocyte and myocyte proliferation and differentiation, contradictory results exists. The preclinical in-vitro and in-vivo work has shown some translation clinically as it supports the evidence for a reduction in delayed onset muscle soreness although no effect was found for acute ischemic muscle pain in forearm.
