Quotes from Various Electromedicine Patents

Patent 6,675,047
Electromagnetic-field therapy method and device
Pulsed [electromagnetic] field therapy produces a complex effect on the living organism, because it contributes to an improvement in the energy metabolism, increases the mobility of lymph, enhances the blood supply of capillaries, and, as a consequence, improves nutrition of all tissues of the organism. The pulse field therapy liquidates stagnation of energy in tissues, whereby painful sensations are eliminated. The pulse therapy improves ion exchange on the level of cells, regulates the intracellular pressure, this contributing to normalization of the overall metabolism.

Patent 7,024,239
Pulsed electromagnetic energy treatment apparatus and method
Electrotherapy includes various means for applying an electric or electromagnetic field to a wound area to facilitate growth and proliferation of new tissue, i.e., healing. Application of external electrical and electromagnetic fields is now an increasingly standard therapy for the treatment of non-union bone fractures, but these devices have seen limited use in other areas of healing. The present invention may also be utilized in other treatment areas where increasing the rate of growth and proliferation of cells is essential, including the treatment of burns and surgically implanted skin or soft tissue grafts, rehabilitation medicine, post surgical repair, and neuronal/brain/spinal injury repair and regeneration.

Patent 6,261,221
Flexible coil pulsed electromagnetic field (PEMF) stimulation therapy system
PEMF therapy has been satisfactorily used in treating spinal fusion, failed arthrodeses, osteonecrosis, and chronic refractory tendonitis, decubitus ulcers and ligament, tendon injuries, osteoporosis, and Charcot foot. During PEMF therapy, an electromagnetic transducer coil is generally placed in the vicinity of the musculoskeletal injury (sometimes referred to as the "target area") such that pulsing the transducer coil will produce an applied or driving field that penetrates to the underlying damaged bone or other body tissue.

Two previous studies had found that electro-magnetic fields (EMFs) reduce pain and swelling. EMFs also have that effect in a new trial headed by orthopedic surgeon Roy K. Aaron. Presumably, he says, it does it "by changing the chemistry of the joint." Studies by his team and others indicate that these fields can increase a joint's production of natural anti-inflammatory agents, such as transforming growth factor-beta. Not surprisingly, Aaron notes, medical supply companies are now developing products, such as a glove with coils, to deliver EMFs to arthritis-ravaged joints. Softer tissues also respond to these fields. For instance, Arthur A. Pilla, a biophysicist at the Mount Sinai School of Medicine in New York City, observes that many people with bone breaks experience significant pain in muscles around their injuries. Shortly after EMF therapy begins, however, that pain disappears. Though the mechanism remains elusive, Pilla says, the treatment seems to affect swelling, which can cause pain. If this proves true, he says, EMFs might benefit people with carpal tunnel syndrome, where swelling in the wrist pinches nerves going to the fingers. Indeed, that's a possibility that Betty F. Sisken of the University of Kentucky College of Medicine in Lexington would like to explore. Currently, she's probing EMFs' direct influence on nerves. In their initial studies, she and her colleagues crushed a nerve in the hind leg of rats and then treated the animals with EMFs for 4 hours daily.
