Decimetre wave therapy (DMV therapy) is a method of local exposure to incoherent unpolarized electromagnetic radiation of a decimeter range (from 1 m to 10 cm) of the corresponding parameters, carried out by means of a radiator located above a certain exposed area of the patient's body at a distance of 3-7 cm or contact.
The EMR wave length used in physiotherapy equipment is 65 cm (frequency of electromagnetic oscillations is 460 MHz) and 32.5 cm (frequency of electromagnetic oscillations is 915 MHz); input power of devices from 5 to 100 watts.
Features of the action of the factor are associated with a nonthermal effect and with the formation of endogenous heat in the tissues of the body. Due to the low energy of the photon of this EMR range with an APM radiation of less than 10 mW / cm 2, a nonthermal effect is manifested, due to such electrodynamic changes as polarization of the corresponding structures, modulation of their intermolecular and electrostatic interactions, as well as some other manifestations, which in turn causes conformational rearrangements of the cytoskeleton, cell membranes and intracellular organelles. Subsequent biochemical reactions, biological processes and clinical manifestations are a consequence of electrodynamic changes and conformational rearrangements of various structures.
With a PPM EMR of this range above 10 mW / cm 2, a thermal effect arises that is caused by an increase in the amplitude of the relaxation oscillations of bound water molecules, glycolipids and some other macromolecules, which leads to a conversion of the EMP energy into thermal energy and causes an increase in tissue temperature. And since the depth of penetration of a given EMR wavelength corresponds to an average of 9-11 cm, local heat formation occurs in the deep-lying tissues and organs. The expediency of this effect raises doubts.
The main clinical effects: anti-inflammatory, secretory, vasodilating, metabolic, immunocorrective.
The equipment: "Wave-2M", "Camomile", "Ranet DMV-20", "Electronics Terma".
Centimeter wave therapy (CMV therapy) is a method of local exposure to incoherent unpolarized electromagnetic radiation from a centimeter range (from 10 cm to 1 cm) of the corresponding parameters, carried out with the help of a radiator located above a certain exposed area of the patient's body at a distance of 5-7 cm or contact .
The EM wave length used in physiotherapy equipment is 12.6 cm (frequency of electromagnetic oscillations is 2375 MHz) and 12.2 cm (frequency of electromagnetic oscillations is 2450 MHz); The input power of the apparatus is from 4 to 150 W.
The effect of the factor is much the same as the previous factor (DMV). The features of CMV therapy are a smaller penetration depth of EMP of this wavelength in the tissues of the body (up to 3-5 cm) and in a more pronounced thermal effect in these tissues with an APM of radiation above 10 mW / cm 2.
Main clinical effects: anti-inflammatory, local anesthetic, metabolic, secretory, vasodilator.
The equipment: Luch-58, Luch-11, Luch-2, Luch-3, Luch-4, Myrta-02.
Extremely high frequency therapy (EHF-therapy, or millimeter wave therapy) is a method of local exposure to incoherent unpolarized electromagnetic! The radiation of a millimeter range (from 10 mm to 1 mm) of the range of the corresponding parameters, carried out with the aid of a radiator, which is located at a distance of 1.5 cm above the certain exposed area of the patient's body or in contact.
The EMR wavelength used in physiotherapy! Equipment, 4-8 mm (frequency of electromagnetic oscillations 57-65 GHz, the exception is the device "Threshold", the range of its frequencies is 30-120 GHz); The input power of the devices is up to 10 mW.
Features of the action of the factor are associated with its small penetrating ability in biological tissues and the lack of a thermal effect from the effect. For EMR of the EHF range, initiation of electrodynamic changes (orientation polarization of cellular and extracellular structures, changing their interrelations) with conformational rearrangements on this basis of biological substrates is also characteristic, and then subsequent reactions, processes and final clinical manifestations.
The main clinical effects: neurostimulating, secretory.
The equipment: "Yav-1", "Helmet-1", "Electronics-KVCH-01", Gtel-2 "," Covert-04 "," Port-1 "," Amphit-0.2 "," Threshold " , "Ariach" and others.
