An assembly of devices designed to apply an electromagnetic (EM) field to body tissues to: 1) treat musculoskeletal disorders (e.g., osteoarthritis, osteoporosis); 2) treat body pain (musculoskeletal, postsurgical); and/or 3) help facilitate soft and hard tissue wound/injury healing, with no production of a therapeutic deep heat. It includes an electrically-powered control unit, application pads/flat coils intended to emit EM radiation to the treatment site (e.g., joint), and carrying case for portability. It is not intended to apply an electric current directly to the body. The system is intended to be used in clinical and home settings.
