Pulsed Electromagnetic Field Therapy is a non-invasive technology that stimulates cellular activity to improve circulation, accelerate tissue repair, pain management, rehabilitation physical therapy.
Application origin
Originated in 1989, Dr. Chokreverty of the United Kingdom and others used magnetic stimulation to assist in the diagnosis of peripheral radiculopathy, thus opening up the application of magnetic stimulation in the field of pain. No matter it is local musculoskeletal pain or ligament, fascia, tendon, synovial membrane, fat, joint capsule and other acute injuries or chronic strain injuries, soft tissue aseptic inflammation, fibrous tissue proliferation, inflammatory tissue adhesion, degeneration and contracture can be improved.
Action mechanism
The magnetic stimulation generator uses high voltage and high energy current to discharge instantaneously in the magnetic field coil to induce a magnetic field with high field strength, which can penetrate the skin and bone tissues without attenuation, induce nerve tissues to generate local micro current, depolarize nerve cells, and excite nerve fibers; At the same time, the magnetic field changes with the current and the output of the magnetic coil. This change generates an induced current, which blocks the direction of the magnetic flux passing through the coil and generates a vortex current, which can stimulate nerves or muscles. The magnetic field affects the distribution of human current, the movement of charged particles, the permeability of membrane system and the magnetic moment direction of biopolymers, changes the physiological and biochemical processes of tissues and cells, and produces analgesia, detumescence, and promotion of blood and lymph circulation. The research shows that the current guided by the magnetic field can obtain the deep part of muscle evoked potential (brachial plexus, lumbar nerve root and sciatic nerve), muscle action potential or sensory nerve action potential in the muscle it controls. The peripheral nerve can only be measured with 70%~75% intensity of 100% of 2.0 T. The induced electric field can enhance the activity of nerve cells and related enzymes, depolarize nerve fibers, generate nerve impulses, easily activate the reflex arc with muscles as effectors, regulate the excitability of peripheral nerves, promote the release of analgesic substances, and improve the pain threshold of the body
