UHF therapy (UHF-therapy) - a method of high-frequency electrotherapy,
based on the application in medical and rehabilitation purposes microwave electromagnetic
oscillations UHF or UHF.
Microwaves have a length of 1 m to 10 cm, which corresponds to an oscillation frequency
of 300 to 3000 MHz.
The CIS devices for UHF-therapy typically operate at a frequency of 460 MHz,
which corresponds to a wavelength of 65 cm, abroad - 915 MHz (33 cm) or 433 MHz (69 cm),
often - in a pulsed mode.
Impact decimeter waves accompanied by a marked (35 to 65%) energy dissipation
in the surrounding space, the rest of the energy penetrates the tissue and is absorbed by them.
It is believed that the microwaves penetrate to a depth of 8-10 cm.
The absorption of energy occurs mainly in tissues that are rich in water,
and is accompanied by heating.
According to modern concepts energy absorption of electromagnetic waves UHF caused
by several mechanisms: the relaxation of polar dipole molecules
(mostly bound water molecules) and ionic conductivity.
UHF absorption occurs due to the resonance mechanism, due to the vibrational motion
of the side chains of proteins, amino acids and glycolipids.
The frequency of these oscillations lies in the UHF band,
which determines the possibility of resonance absorption of UHF.
The energy absorption decimeter waves is accompanied by heat generation and the various physical
and chemical shifts, leading to an acceleration of the diffusion and exchange processes,
changes in the conformation and the permeability of cell membranes,
the activity of enzymes and bioactive compounds,
shifts potassium-sodium ratio, activity of cellular respiration modulation intermolecular
and electrostatic interactions in a cell, and others.
These initial changes occurring during energy absorption decimeter waves,
directly or indirectly (reflexively) affect various functions of organs and systems, thereby determining the physiological and therapeutic effect of UHF-therapy.
The use of UHF is accompanied by both local and general changes in the body.
At the heart of local changes is primarily a thermal effect of microwaves.
The extent of tissue heating by irradiation depends on the length of the procedure,
the sizes of the irradiated area, and biophysical properties of the dosage of irradiated tissues
. At the UHF-therapy most strongly heats the blood, lymph, muscles and water-rich tissue.
Temperature therein can increase to 4-6 ° C under a relatively low heating the subcutaneous fat layer.
It should be emphasized that the UHF-therapy indicated more uniform than with
other methods of high-frequency electrotherapy, heating of tissues.
Heating and other tissues occurring in these primary changes lead to the expansion
of capillaries, enhance microcirculation and regional blood flow,
increased permeability of microvascular and dehydration inflamed tissues,
decongesting, stimulating the barrier function of the connective tissue.
Under the influence of UHF activates the metabolism of irradiated tissue,
improves trophism and to restore the broken functions.
UHF increase production of releasing factors in the hypothalamus,
the pituitary gland stimulates the synthesis of hormones and some peripheral endocrine glands,
increase the share of the free fraction of the hormones,
causing inhibition of the activity of immune cells.
They increase the content of T-lymphocytes and reduces the content of B lymphocytes
and some immunoglobulins.
Under their influence, improves conditioned reflex activity of the brain, it increases blood flow
and neuronal activity, activates the synthesis of nucleic acids,
prostaglandins and other metabolites.
On brain circulation UHF-therapy acts favorably and with his pathology.
UHF-therapy leads to a slowing of the heart rate, strengthening myocardial contractility,
a moderate decrease of blood pressure, contributes to the development of collateral vessels
and induces reparative processes.
UHF-therapy procedure restores impaired respiratory function, has a bronchodilator
and anti-inflammatory effect
. The action of UHF on the abdomen stimulation dominates the main functions
of the stomach, intestines and liver, as well as reparative processes in them
UHF-therapy stimulates the kidneys, increases renal blood flow
and glomerular filtration, has a pronounced anti-inflammatory effect with urogenital pathology.
UHF-therapy improves the rheological properties of blood, activates its antisvertyvayuschey system.
The main therapeutic effects are UHF anti-secretory, a vasodilator, an immunosuppressive, metabolic.
Procedure and dosing UHF-therapy.
Exposure to decimeter waves is performed on the exposed surface of the patient's body
in a lying or sitting position. From exposure area remove all metal objects.
For the impact on small plots and head area use portable devices,
the emitter is applied without pressure directly to the patient's body (contact method).
When the remote procedure emitters positioned over the irradiated surface with
an air gap of 3-5 cm (typically stationary devices).
When intraorganic effects corresponding radiator cap with a plastic or rubber bag,
treated with alcohol is introduced into the body cavity and fixed.
Microwaves metered output power and thermal sensations patients.
Accepted provide slaboteplovaya, thermal and silnoteplovaya exposure dosage
. Tentatively for fixed devices to 30-35 watts output power is considered slaboteplovaya
dose of 35-65 watts of heat above 65 W - silnoteplovaya.
For portable devices this division is as follows:
up to 6 W output power is considered slaboteplovaya, 6-9 W - thermal and more than
10 watts - silnoteplovaya.
Pay attention to the condition of the skin in the area of radiation:
when slaboteplovaya dosages skin color does not change,
when the heat is celebrated slight hyperemia.
During the procedure, can not allow the appearance of a burning sensation in the patient.
When complaints of burning is necessary to reduce the output power.
The duration of exposure to microwaves is from 4-5 up to 10-15 minutes on the field.
The total duration of UHF-therapy should not exceed 30-35 minutes.
After the procedure is desirable rest for 15-20 minutes.
UHF-therapy is administered daily or every other day, a course of treatment administered from 3-6 to 12-16,
at least - 16-20 procedures.
If necessary, after 2-3 months of repeated course UHF-therapy can be carried out.
Babies procedure prescribed 2 years using only the portable devices.
For children irradiation is performed at an output power 3.2 W for 8.5 min.
In older children treatment time is gradually increased to 8-12 minutes,
if necessary exposure may be performed in thermal dosages.
In the field of pathological accumulation of liquids, as well as in various
bone protrusions procedure should be performed with caution.
Avoid direct exposure to high-intensity UHF eyes and genitals.
For eye protection use special glasses (such as ARD-5).
During the procedure, you must observe the following rules:
1) the procedure must only be performed on chairs and couches made of wood
or other insulating material;
2) the lower edge of the shielding curtains must be spaced from the cab floor is not more than 2 cm;
edge of the curtains, forming the entrance to the cabin, must go to each other for at least 10-15 cm;
3) during the procedure the patient should stay as far away from the shielding surface to minimize
the risk effect is not accounted scattered energy;
4) during the procedure the patient should not touch the water pipes, sewage
and heating systems;
5) at the contact exposure method can not be strongly pressed to the body of the radiator,
it must be set almost touching the skin or mucosa.
Strong pressing of the transmitter can disrupt regional circulation or even burns,
which may not be immediately apparent, but after 1-2 days for subsequent procedures;
6) work surface radiators must be treated with a disinfectant solution.
Protective cap of cavity radiators after the procedure disinfected by boiling in water;
7) the devices must take breaks for 10 minutes after each hour of work.
