Indications for pulse electromagnetic field PM treatment
PM technology is currently the latest physical technology widely used in orthopedics, pain management, and rehabilitation for muscle, joint, tendon, and bone pain. It leads the new trend of pain development with non-invasive methods, and has advantages such as no side effects, no trauma, no radiation, no medication, and no surgery. It is also easy to operate, has a short treatment time, and takes effect quickly.
Application Origin
Originating in 1989, Dr. Chokroverty and others in the UK used magnetic stimulation for the auxiliary diagnosis of peripheral nerve root disease, thus opening up the application of magnetic stimulation in the field of pain. Whether it is local musculoskeletal pain or acute or chronic soft tissue inflammation, fibrous tissue proliferation, inflammatory tissue adhesion, degeneration, and contracture caused by ligaments, fascia, tendons, synovium, fat, joint capsules, etc. can be improved.
Mechanism of action
The magnetic stimulation generator utilizes high voltage and high-energy current to instantly discharge within the magnetic field coil, inducing a high field strength magnetic field that can penetrate skin and bone tissue without attenuation, inducing local microcurrent in nerve tissue, depolarizing nerve cells, and exciting nerve fibers; At the same time, the magnetic field changes with the current and the output of the magnetic coil, which generates induced current. The induced current obstructs the direction of the magnetic flux passing through the coil, generating a vortex current that can stimulate nerves or muscles. Magnetic fields affect the distribution of electric currents in the human body, the movement of charged particles, the permeability of the membrane system, and the magnetic moment orientation of biopolymers, causing changes in the physiological and biochemical processes of tissue cells, resulting in analgesic, anti-inflammatory, and promoting blood and lymphatic circulation. Research has shown that magnetic field guided currents generate deep muscle evoked potentials (brachial plexus, lumbar nerve root, and sciatic nerve), muscle action potentials, or sensory nerve action potentials in the muscles they innervate. Peripheral nerve measurements only require 70% to 75% intensity of 100% 2.0 T. Induced electric fields can enhance the activity of nerve cells and related enzymes, depolarize nerve fibers, generate nerve impulses, easily activate reflex arcs with muscles as effectors, regulate the excitability of peripheral nerves, promote the release of analgesic substances, and increase the body's pain threshold.
Chronic pain refers to pain that lasts for more than a month (previously three months or six months), and some people compare chronic pain to an immortal cancer.
Due to the degeneration of cervical intervertebral discs and degenerative changes in surrounding soft tissues, nerve roots are stimulated and compressed, leading to local circulatory disorders and the formation of aseptic inflammation, resulting in pain. Chronic pain may be an excessive plasticity change between synapses in the pain transmission pathway, leading to an increase in pain sensitivity. The low-frequency stimulation of the magnetic field to the peripheral pain site not only produces a long-term inhibitory effect on synaptic connections in the pain transmission pathway, but also selectively stimulates the peripheral coarse fiber nerves. Through the gating effect of spinal pain transmission, it blocks the transmission of C-class fine fibers that transmit pain and achieves better long-term analgesic effects.
One of the most common types of neuropathic pain is stubborn pain that troubles middle-aged and elderly people. Magnetic field can stimulate the nerve roots of patients with herpes zoster pain through magnetic stimulation, which can inhibit ectopic discharge of damaged peripheral afferent fibers, reduce neuronal interaction and mixing, inhibit the excitatory effect of sympathetic nervous system on damaged neurons, and treat postherpetic neuralgia from the fundamental mechanism of nerve conduction.
Chronic back pain is often caused by the gradual progression of acute illness, which can lead to psychological and mental problems that seriously affect the patient's work and life. Parallel the magnetic field handle to the level of waist 4/waist 5 in patients with chronic lower back pain, stimulate the nerve roots at the frequency of MT, and its combination with exercise has a more significant effect on relieving pain. Chronic lower back pain, due to its long course, may be related to brain plasticity in its mechanism. Magnetic stimulation causes periodic muscle contraction/relaxation, which can induce periodic changes in the patient's proprioception, induce brain remodeling, activate the descending pain pathway and spinal cord inhibition mechanism to improve pain symptoms, and activate the descending pain pathway and spinal cord inhibition mechanism to improve pain symptoms.
