Actions of PMF
Vasodilatation can be caused by Ca2+ that, as a consequence, causes relaxation of the vascular musculature, mainly in preacapillary sphincters. The role of parasympathetic activation can be considered as well. On the basis of the enhanced metabolic activity in the exposed area (endothelial cells, including), higher production of EDRF can be considered, as can increased prostacyclin production. Finally, mastocyte activation and M and N receptor block can contribute to this effect.
Analgesic action can be explained by proved enhanced endorphine production as well as by anti-inflammatory and anti-oedematous activity and by spasmolytical action, e.g., in paravertebral muscles. It does not seem plausible that, as in animals, destruction of nerve endings and nerve fibers occurs. This should cause skin sensoric disturbances that have never been seen with the exception of professionals. However, this effect onsets after 1-2 years of employment.
Anti-inflammantory action - theoretical rationale was proposed by J. Jerabek (1989, 1990) based on the above-described observations.
It explains how magnetotherapy works. It is known that PMF affects cellular levels. PMF causes the activation of enzymatic processes, metabolic transfers, and functions of the cellular membrane. Cellular respiration is activated in the exposed area. PMF produces positive changes in the immunological condition of the patient, including vasodilatation of the arterial part of the capillaries and decreased blood coagulation.
The therapeutic aim of the magnets is to balance the energy stream in the meridians and chakras of the body.
Meridian and chakra pleonasm results from a superfluous energy stream in them, which the organism can't independently neutralize. Such a condition of the energy system, as well as the opposite deficiency, can entail the development of disease. An influence on the energy system is performed with stimulation or suppression of the meridians and chakras by magnets. Magnet therapy can have a frank influence on the bodily as well as mental state of a person. This is due to the energy system, which has control over all other systems of the body.
The high sensitivity of the central nervous system is marked by magnet efficacy. Magnet fields eliminate chronic pain, intensify blood circulation, give a vasodilating effect, and influence blood coagulation. Application with the medicative purpose of magnet fields renders antiedema, anti-inflammatory, antipruritic, anesthetizing, and antiallergic action. Magnet fields positively influence the heart. They affect its functions: by decreasing myocardium oxygen demand and increases myocardial blood flow.
At the treatment of tension of ligaments, bone fractures, ambustion, and brine slits, magnetotherapy promotes not only recuperation but also allows for faster results with fewer adhesions and a good cosmetic effect.
At traumas, magnetotherapy reduces the healing process by two or more times. While treating chronic problems, such as some forms of an arthritis, degenerate conditions, diabetic ulceration, and cancer, magnetotherapy has shown magnificent results, occurring in amelioration or recuperation. Fine results are received using the therapy with magnets for the treatment of extensive soft-tissue damage like decubitus ulcers, ambustions, and many others.
Every year, magnetotherapy is gaining increasing recognition in medicine. It is connected, on the one hand, with the insignificant list of contraindications and, on the other hand, with the wide list of indications.
