The problem of pain management is a very pressing health and socioeconomic problem. Acute, recurrent and chronic forms of pain are prevalent in age, cultural background and gender, and the cost of adults in North America is estimated to be between $10,000 and $15,000 per person per year. The cost of pain is estimated to include nearly 30,000 people who die in North America each year due to aspirin-induced stomach problems. 17% of people over the age of 15 suffer from chronic pain and interfere with their normal daily activities. Studies have shown that at least one-quarter of adults in North America suffer from some form of pain at any given moment. This large group of painful people relies to a large extent on the medical profession to provide medical treatment. Many doctors now refer to patients with chronic pain as non-drug therapy, "replenishment and alternative medicine," to reduce drug dependence, invasive procedures, and/or side effects. The challenge is to find the least toxic, difficult, and expensive methods.

Depending on the source or location of the pain and whether the pain is acute or chronic, the ability to relieve pain is variable and unpredictable. The pain mechanism is complex and has peripheral and central nervous system aspects. Treatment should be adjusted according to the specific conditions of the individual patient's pain process. Psychological problems have a big impact on whether and how pain is experienced and whether it will become chronic. The most effective pain management strategies require multiple concurrent methods, especially chronic pain. A single modality rarely solves the problem.

In the past few years, people have increasingly studied a new, fundamentally different approach. This includes the use of magnetic fields [MF] generated by static [permanent] and time-varying [most common, pulsed] magnetic fields [PEMF]. Various fields of strength and frequency have been evaluated. There is currently no "gold standard." The selected fields will vary based on experience, confidence, convenience and cost. Since there seems to be no major advantage for any MF application, mainly because it is impossible to determine the true potential source of pain, regardless of the presumed pathology, any method can be used empirically and adjusted for treatment based on the response. After thousands of years of use worldwide, the risks associated with MF treatment are found to be small. The primary preventive measures involve implanted electronic devices and pregnancy and seizures with certain frequency patterns in seizure individuals.

Magnetic fields affect pain perception in many different ways. These actions are both direct and indirect. The direct effects of the magnetic field are: neuronal discharge, calcium ion movement, membrane potential, endorphin levels, nitric oxide, dopamine levels, acupuncture behavior and nerve regeneration. The indirect benefits of magnetic fields on physiological functions are: circulation, muscle, edema, tissue oxygen, inflammation, healing, prostaglandins, cellular metabolism, and cellular energy levels.

Most studies of pain use subjective measurements to quantify baseline and outcome values. The subjective perception of pain using visual analog scale [VAS] and pain pictures is 95% sensitive and 88% specific for current pain in the neck and shoulder as well as the thoracic spine.

The measured pain intensity [PI] varies with pain relief and satisfaction with pain management. Based on the Digital Descriptor Scale [NDS] and the Visual Analog Scale [VAS], the average reduction rate of PI in the emergency room environment was 33%. The 5%, 30%, and 57% reductions in PI were associated with "no", "some/part" and "significant/complete" mitigation. If the initial PI score is moderate/severe pain [NDS 5], the PI must be reduced by 35% and 84%, respectively, to achieve "partial/partial" and "significant/complete" remission, respectively. Patients with less pain [NDS < or = 5] need to reduce their PI by 25% and 29%. However, the relief of pain seems to only partially promote overall satisfaction with pain management.

Some authors reviewed the experience of Eastern European and Western Pulsed Magnetic Therapy [PEMF]. PEMF has been widely used in many conditions and medical disciplines. They are most effective in the treatment of rheumatic diseases. PEMF significantly reduces pain, improves spinal function and reduces paravertebral paralysis. Although PEMF has proven to be a very powerful tool, they should always be used in conjunction with other treatment procedures.

Certain pulsed electromagnetic fields [PEMF] affect bone and cartilage growth in vitro and may be used as arthritis therapeutic applications. PEMF stimulation has proven to be an effective method for delaying fractures and can be used for osteoarthritis, osteonecrosis, osteoporosis and wound healing. In some cases, static magnets can temporarily relieve pain.

The ability of PEMF to affect pain depends on the ability of PEMF to have a positive impact on a person's physiology or anatomy. Studies have shown that the human nervous system is strongly affected by therapeutic PEMF. Animal behavior and physiological responses to static and very low frequency [ELF] magnetic fields are affected by light.

One of the most reproducible results of weak, very low frequency [ELF] magnetic field [MF] exposure is the effect on neural pain signal processing. Pulsed electromagnetic fields [PEMF] have been designed to treat chronic pain in humans. Recent evidence suggests that PEMF is also an effective complement to patients with acute pain. Recent studies have also shown that magnetic field treatments involving the manipulation of rest balance can effectively determine the cause of chronic pain and thus effectively diagnose potential disease states. Static magnetic field devices with strong gradients have also been shown to have therapeutic potential. It has been shown that a specially placed static magnetic field device, such as a Magnabloc device, can reduce nerve action potentials in vitro and alleviate spinal cord-mediated pain in human subjects. Human studies involving induced analgesia, whether using pharmacology or magnetic field therapy, also require consideration of a placebo response, which can explain up to 40% of analgesic responses. However, a placebo response or at least a central nervous system mechanism responsible for a placebo response may be a suitable target for magnetic field induction therapy. Magnetic field manipulation of cognitive and behavioral processes has been well documented in animal behavioral studies and subjective measurement studies involving human subjects, which may also be one of the mechanisms for the treatment of pain using MF.

Since the beginning of this century, many electrotherapy, magnetic therapy and electromagnetic medical devices have been developed for the treatment of broad-spectrum wounds, tumors and infections with static, time-varying and/or pulsed fields. Over the years, some of these non-invasive devices have proven to be very effective in certain applications, particularly bone repair, pain relief, autoimmune and viral diseases [including HIV] and immune enhancement. Their acceptance in clinical practice is very slow in the medical profession. Practitioner resistance appears to be based primarily on different forms of confusion, the various frequencies used [from ELF to microwave] and the general lack of understanding of the biomechanics involved. The current scientific literature suggests that short-pulse periodic exposure to pulsed electromagnetic fields [PEMF] has become the most effective electromagnetic therapy.

Magnetic therapy is accompanied by an increase in the threshold of pain sensitivity and activation of the anticoagulant system. PEMF treatment stimulates the production of opioid peptides; activates mast cells, Langerhans and Merkel cells, promotes vacuolation of the sarcoplasmic reticulum, and increases the capacitance of the muscle fibers. Long bone fractures that did not heal within 4 months to 4 years were repaired in 87% of cases, and daily PEMF treatment was 14-16 hours. Some of these devices have received FDA approval. PEMF with a field strength of 1.5 or 5 mT proved to be beneficial for edema and pain before or after surgery. The findings and PEMF experience demonstrate the wider introduction of PEMF treatment technology in clinical practice.

Treatment of bone pathology, nerve and ligament regeneration, pain and inflammation prompted the study of the underlying mechanisms of action. These studies have focused on the effects of changes in membrane transport activity and small changes in ion flux on metabolism, cAMP levels, and stimulation of mRNA and protein synthesis. A specific combination of a limited number of EMF parameters stimulates cellular activity. Deviating from these particular field characteristics may have the opposite effect. PEMF is 15-360 minutes and amino acid uptake is increased by about 45%. The intake of AIB then gradually decreased, but was still significantly higher than the control after 6 hours in the exposed skin. The effect of PEMF on the conformational change of the 2-hour induced transmembrane energy transporter was compared, allowing the energy coupling and absorption of the resonant PEMF energy to be transduced into transport work.

Since 1990, Italy has been studying the effects of EMF on the response of animals to adverse environmental stimuli. Researchers have shown that ELFs can reduce the density of meningeal opioid receptors by about 30% and reduce pain. Similar to Canadian researchers in mice and snails with various MFs. Found that 2 hours of exposure to healthy people can reduce pain and reduce pain related brains…
