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. In one 6-day-long experiment,
the treatment speeded the nerve's recovery by 22 percent.
In follow-up tests, where 16 rats received EMFs for 40 days
and an equal number were allowed to heal unaided, treated
animals again showed an accelerated
recovery.
