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.

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. |
