Traditional pulse electromagnetic field (PEMF) devices have been approved by the U.S. Food and Drug Administration (FDA) to treat nonunion fractures and cleared to treat post-operative pain and edema, osteoarthritis, and plantar fasciitis. However, high level of evidence indicated that the lack of beneficial effects of PEMF on pain, function or range of motion in the treatment of shoulder pain.~High energy density pulse electromagnetic field(High-PEMF) which builds up a voltage up to 30 kilovolt (kV) with shorter impulse time(50us) and broad band-width(200kHz~300MHz) is very different from traditional PEMF. Magnetic field about 50~150 millitesla (mT) is created and it can penetrate the body up to 20 cm. The aim of our study is to investigate the efficacy of High-PEMF for patients with rotator cuff tendinopathy.
