Mechanism of magnetic fields physical and therapeutic effect

Action of magnetic field on an organism is characterized by:

  • Differences in individual sensitivity to magnetic field exposure
  • Remedial effect of magnetic field on an organism and its functional systems
  • Degree of therapeutic action intensity: effect and changes in organs are more evident with the influence of alternating and pulsed magnetic field, than that of the constant one
  • Magnetic field application aftereffect. Reaction of an organism is kept within 1-6 day after magnetic field single-action, and after the taken procedure course - 30-45 days, this stipulates necessity to make break between repeated magneto-therapy courses for chronic diseases treatment.
  • Influence of magnetic field on background of organ or system increased function results in its decrease, and application of magnetic field in the state of function depression is accompanied with its elevation.

Organism organs and systems have different reaction upon the action of magnetic field. Organism response reaction selectivity depends on tissue electric and magnetic properties, their difference in microcirculation, metabolism intensity. According to organism systems degree of sensitivity to a magnetic field, nervous system takes the first place then come endocrine systems, sense organs, cardiovascular, muscular, digestive, secretory, respiratory and skeletal (osteal) systems. At influence by low intensity magnetic fields on nervous system central parts and reflex zones there are the changes of conditioned-reflex function, physiological and biological processes. The most evident reaction of the organism from central nervous system reveals itself in hypothalamus, then comes cerebral brain cortex, hippocampus, reticular formation of midbrain. As a result there is inhibitory processes resulting in sedative and healthiness effect of magnetic field to sleep and emotioanal excitement of the organism.

From the part of hippocampus there is noted synchronization of secretory cells function, activation of synthesis and getting neurosecretory substance out of its nucleus as a result of the magnetic field exposure. At the same time there is increase of hypophysis portions functional activity. However under the long and great (more than 70 mTl) magnetic field exposure there can be depression of neurosecretory function and development of productive dystrophic processes in CNS (central nervous system) cells.

So as result of the action of low intensity magnetic field we have evident positive effect: reduction of cerebral vessels tone, improvement of brain blood supply, activation of nitrogen and carbohydrate - phosphoric metabolism intensifying brain stability to hypoxia.

Under the influence of magnetic field on cervical sympathetic nodes (suboccipital or transcerebral area) there is improvement of cerebral blood flow (the data of rheovasography).

Under the influence of magnetic field on suboccipital area (patients with a circulatory insufficiency invertebrobasilar system) there is evident improvement of cerebral hemodynamics.

Thus, with the help of alternating magnetic field there may be correction of cerebral hemodynamics abnormality with various pathological states.

There is noted the reaction of peripheric nervous system to action of a magnetic field:

  • Decrease of peripheric receptors pain sensitivity threshold resulting in anesthetizing effect with traumas
  • Improvement of conductivity function stimulating the restoration of injured peripheric nerve endings functions, due to the better axons growth, myelination and inhibition of connecting tissue development in them.

Stimulation of hypothalamo-hypohpysial system causes chain reaction of peripheric endocrine glands activation under the influence of release-factors. In endocrine system under the influence of alternating magnetic field with induction up to 30 mТl, frequency up to 50 Hz during the little exposition (20 minutes) there is development of both training reaction and excess activity of all parts of endocrine system.

From the part of thyroid gland there is noted stimulation of its function under action of magnetic field, in contrast to suppressive effect of many others stimulus, that gives the background to use magnetic fields in complex therapy.

The sympaticoadrenal system is slightly activated within the first procedures, and by the 7-9th day there is inhibition of peripheric adrenoreceptors which plays the important role in the formation of antistress effect.

The influence of alternating traveling pulsed magnetic field on collar zone there is a reaction from cardiovascular system that gives the ground to suppose the reflex nature of these fields action.

There is marked decrease of blood pressure in system of deep hypodermic veins and arteries, simultaneously, increase of vessels walls tonus, the change of elastic properties and bioelectric resistance of blood vessels walls.

Change of hemodynamic, including hypotensive effect, is connected with the development of bradycardia effect and decrease of myocardium contractive functions.

This property founds its application for idiopathic hypertensia treatment and also is used to reduce heart burden with stenocardia.

Magnetic field makes the influence for the development of changes in various tissues microcirculatory canal.

At the beginning of the process of magnetic field influence there is short time (5-15 minutes) slowing-down of capillary blood-flow which lately changes for microcirculation intensification.

During the time and upon the termination of magnetotherapy course there are acceleration of capillary blood flow, improvement of vascular wall contractive abilities and increase of vessel blood accumulation. Enlagement of microcirculatory canal functioning components lumen promotes the opening of previous capillaries, anastomoses and shunts.

Under the influence of magnetic fields there is increase of vascular and epithelial permeability, direct result of which is accelaration of both edema and taken medicinal substances resorption.

Due to this effect, magnetotherapy has found its wide application to liquidate edemas of various aetiology (traumatic, inflammatory).

Under the influence of permanent alternating treveling magnetic field there is incease of metabolic processes in bone regeneration area (with fracture), at earlier period there is occurrance of fibrous and osteoblasts in a zone of regeneration, process of osteal substance formation is going on more intensively.

Under the influence with magnetic fields there is the change of rheological properties of blood. Hypocoagulation effect is marked due to:

  • Activation of anticoagulative system
  • Decrease of intravascular parietal thrombosis
  • recrease of blood viscosity due to the action of low intensity magnetic fields on enzymatic processes, electric and magnetic properties of blood elements taking part in hemocoagulation .

The action of a magnetic field renders considerable influence on metabolic processes in organism.

Under the action on organism particular systems there is increase both of the amount of albumens and globulins in blood serum and their concentration in tissues due to α - and γ - globulin fractions resulting in the change of albumen structure. With short-term daily action of magnetic fields on an organism there is reduction of pyruvic and dairy acids content not only in blood, but also in liver and muscles resulting in incrase of glycogen content in a liver.

There is reduction of ions Nа content with simultaneous rising of ions K concentration in the tissues due to the action of magnetic field , that is the evidence of the change of cellular membranes permeability.

It is marked the reducrion of Fе content in a brain, heart, bloods, liver, muscles, spleen ( lien) and its increase in an osteal tissue. This Fe redistribution is connected to change of hemopoiesis organs state .

Besides there is increase of CU content in in heart muscle, lien, spermaries that stimulates adaptive-compensatory processes of an organism. Cо content in all organs reduces and there is its redistribution between blood, separate organs and tissues. Under influence of a magnetic field there is increase of Mg biological activity. It results in decrease of the development of pathological processes in a liver, heart, muscles. It is noted, that magnetic fields of low induction stimulate processes of tissue respiration, changing a balance of free and phosphorylate oxidations in respiratory chain. Increase of nucleic acids and albumen synthesis exchange resulting in acceleration of trophicoregenerative processes.

Tipical manifestation of action of magnetic field on an organism is activation of processes of carbohydrates and lipids metabolism. The last is shown in the increase of nonesterificated fat acids and phospholipids in blood and internal organs, decrease of cholesterin in blood.

Thus, the short time action by magnetic field on human organs and systems has a number of beneficial effects:

  • Analgesic
  • Anti-inflammatory
  • Anti-edematous
  • Trophico-regenerative
  • Hypotensive;
  • Sedative actions

With influence on large vessels, magnetotherapy renders disagregative and hypocagulatory effects, improves microcirculation and regionary blood circulation, favorably influences immunoreactive and neurovegetative processes. Magnetic field action, as a rule, does not cause formation of endogenic heat, rise in temperature and skin irritation .

It is marked the good tolerance of magnetotherapy by the weak patients, advanced age patients, suffering with accompanying diseases of cardiovascular system that allows to apply magnetotherapy devices in many cases when influence with other physical factors is not indicated.
