Basic Scientific Research / Other Applications / Review Articles
PEMF therapy has been used successfully in the management of postsurgical pain and edema, the treatment of chronic wounds, and in facilitating vasodilatation and angiogenesis. This review article was co-authored by a multidisciplinary group of medical doctors and Ph. D researchers including Nobel Laureate in Medicine, Louis Ignarro, Ph.D. who elucidated nitric oxide’s role in the body’s anti-inflammatory response.

Clinical effects in this group of “no option cardiac patients” showed steady improvement in clinical symptoms which persisted at two months after cessation of PEMF therapy. Clinical Improvement lasted for 25 months after cessation of treatment suggesting longer treatment regimen may be warranted – Cleveland Clinic.
