The effects of pulse magnetic therapy can be divided into several basic groups. These effects are key to how efficient the treatment is.
Low-frequency pulse magnetotherapy (PEMF) causes generation of electric current in nerve fibres due to magnetic induction. This induced current blocks passage of pain perception from the painful area through the spinal cord all the way to the brain centres. Pain is suppressed as a result of this and other mechanisms. These other mechanisms include an increased production of endorphins and suppression of inflammation and swelling. Myorelaxation, or relaxation of muscle, also plays its part.
The increased secretion of endorphins and regulation of calcium ions transferring through cell membrane also contributes to vasodilatation, the analgesic effect, and relaxation.
An increased activity of lactate dehydrogenase in exposed muscles has been found after application of pulse magnetotherapy. Lactate dehydrogenase promotes degradation of lactic acid, which triggers nerve receptors and causes pain.
Pulse magnetotherapy (PEMF) with well-set parameters works against erythrocyte rouleaux, i.e. stacking of red blood cells, which transfer oxygen in blood. The resulting effect is dispersion of individual erythrocytes thus expanding the total surface capable of binding oxygen. Blood which went through an appropriate pulse magnetic field shows an improved ability to become oxygenated and to transfer this oxygen to tissues.
When pulse magnetotherapy is being applied, parasympathetic nerves are activated and Ca2+ ions are refluxed, which leads to dilation of vessel muscles (pre-capillary constrictors in particular) and subsequent vasodilation.
Application of a low-frequency pulse magnetic field (PEMF) has an effect on the polarisation of red blood cells by means a positive charge. Polarisation of erythrocytes affects muscle tension of arteries, arterioles and capillaries. This leads to dilation of the bloodstream (vasodilation and improvement of microcirculation), and therefore to an enhanced supply of oxygenated blood and nutrients into tissue. Improved microcirculation contributes to a faster removal of toxins and metabolites from tissues.
Pulse magnetotherapy (PEMF) also significantly increases partial pressure of oxygen and affects erythrocyte plasticity, or flexibility, in other words. The more flexible erythrocytes are, the easier their passage through the blood stream is. With long-term applications of this method, neovascularisation takes place. That means that new vessels are created more quickly.
Pulse magnetic field applications (PEMF) also lower the risk of blood clots (thrombus).
Pulse magnetotherapy (PEMF) proceeds through human tissue evenly, and thus is one of very few methods which can be effective in internal inflammation.
Pulse magnetotherapy (PEMF) passes through every cell in the area of application and induces weak electric current. Due to the induction of electric current, the cell surface potential is changed and membrane permeability affected. This results in better metabolism, blood supply, and cell oxygenation. Better nutrition and elimination of metabolic waste from tissues is essential to any detoxification process.
The liver is the main detoxification organ in the human body, and that is why it is advised to target it for application of pulse magnetotherapy (PEMF). Liver activity can be promoted by sufficient hydration, and this hydration can be achieved by consuming magnetised liquid. It goes through a process where changes in water structure are achieved by applying a pulsed magnetic field. Water treated in this manner has improved capability of binding oxygen molecules and is softer, therefore it is better able to dissolve and eliminate metabolic waste.
Swelling is caused by insufficiency in the blood stream on the capillary level with subsequent accumulation of liquid between cells.
The goal of pulse magnetotherapy application is to work against the main causes of swelling. That means against high blood pressure in capillaries (the smallest vessels in the human body), against impaired transfer of water from tissues, and also against a possible increase of the permeability of capillary walls.
Improved perfusion, i.e. the flow through tissues, plays an important role in the anti-swelling effect of pulse magnetotherapy (PEMF).
As the metabolism accelerates after application of pulsed magnetic therapy (PEMF), swelling is absorbed faster and there is enhanced anti-inflammatory and analgesic effect in the area of application.
The anti-swelling effect of pulse magnetotherapy (PEMF) is a result of a combination of vasodilation and regeneration effects and is an essential part of healing.
Pulse magnetotherapy (PEMF) causes acidic metabolites to flow away faster. These acidic metabolites cause painful irritation in muscles and areas of chronic inflammation.
It is improved perfusion (improved flow through tissues) and increased activity of lactate dehydrogenase that starts elimination of lactic acid.
Muscle spasm gets increasingly diminished by application of pulse magnetotherapy (PEMF). The therapy also lowers radicular irritation, which often causes a tingling sensation and pulsing or burning pain.
Due to the fact that pulse magnetotherapy (PEMF) supresses pain, there are alterations of reflex changes in the body. Altering these body reflexes causes muscle spasms or contractures and cramps to relax. The result of this is further relief from pain.
Application of magnetic therapy (PEMF) leads to a myorelaxing effect on skeletal muscles and improves mobility. This improvement in mobility allows for further therapy in the form of easier rehabilitation exercise.
The healing and regenerative effect of pulse magnetotherapy (PEMF) on bones and soft tissues is explained by non-specific cytoplasmic membrane irritation. On the surface of this membrane, activation of the metabolic chain whose key point is change in the cAMP/cGMP ratio, (i.e. a change of ratio between cyclic adenosinmonophosphate and cyclic guanosinmonophosphate) happens.
In case of utilising regenerative effect on bones, the application results in increased osteoclast activation and a subsequent launch of the regenerative process of bone tissue. Pulse magnetotherapy (PEMF) significantly accelerates healing, activates production of new tissue, calcification, and leads to increased sensitivity to parathormone, which among other things helps regulate the level of calcium in the body.
Better blood perfusion and higher oxygen saturation promotes faster healing of inflammation in all tissues, and also potentiates effects of antibiotic treatment.
There is also a significant acceleration in healing of damaged peripheral nerves and regeneration of neurofibrils and growth of central axons (fibres coming from cells).
