UHF therapy - indications, contraindications and secrets of the procedure

UHF therapy is one of the popular methods widely used in the treatment of ENT diseases, diseases of the musculoskeletal, nervous, genitourinary and other body systems. Therapeutic manipulations can be carried out both in a medical institution and at home.

What is UHF?

The name of this procedure is deciphered as follows: ultrahigh-frequency therapy. This technique involves exposure to problem areas with a strong or weak electromagnetic field. The oscillation frequency can be 27.12 MHz or 40.68 MHz. During this procedure, two electric fields act simultaneously: one comes from the apparatus, and the second from the human body.

Lymph, urine and blood have high current conductivity. In these liquids, charged particles oscillate at the same frequency as in an electromagnetic field. In addition, energy is absorbed in this medium, accompanied by heat release. In this case, a directly proportional effect is observed. In other words, the more energy absorbed, the stronger the thermal effect. Based on this, UHF is warming up (as it is called in the common people). This corresponds to the effect on the body.

UHF action

Such a procedure has a considerable list of effects on the body. UHF radiation affects:

  • reduces pain;
  • reduces pressure;
  • fights inflammation;
  • reduces puffiness;
  • stimulates blood circulation;
  • has a desensitizing effect.

UHF therapy device

Two types of equipment are used to carry out such procedures:

  • stationary;
  • portable.

The first group includes the following devices:

  • UHF-300;
  • Impulse-2;
  • Screen-2;
  • Impulse-3.

The most commonly used portable equipment is:

  • UHF-30;
  • UHF-66;
  • UHF-80-04.

The standard fixture has the following components:

  • generator – generates energy;
  • inductors – thanks to them, the UHF device creates a magnetic field;
  • electrodes – conduct electricity;
  • emitters.

UHF – indications and contraindications

This manipulation has a wide range of applications. At the same time, the UHF procedure has a considerable list of contraindications. Before its implementation, you need to weigh all the positive and negative features. Only a doctor can accurately do this. Self-medication is dangerous! Even if the procedures are performed at home, they should be carried out under the supervision of a doctor.

UHF therapy – indications

UHF therapy indications

When prescribing this therapy, the doctor takes into account the following factors:

  • patient’s age;
  • the intensity of the manifestation of the disease;
  • concomitant diseases;
  • presence of contraindications to the procedure.

UHF therapy is used to combat inflammation that is in the active stage. During this period, an infiltrate is formed in the body due to the accumulation of lymph and blood cells. UHF therapy promotes its resorption. In the problem area, the amount of calcium ions increases. As a result, connective tissue forms around the focus: it serves as a barrier that prevents the spread of infection. However, this method of physiotherapy can be used only in cases where pus drains from the area affected by inflammation.

UHF indications for implementation are as follows:

  1. ENT diseases (bronchitis, frontal sinusitis, otitis, sinusitis, and so on) – the procedure inhibits the vital activity of pathogenic microorganisms. At the same time, such physiotherapy strengthens the immune system and has an analgesic effect. In addition, UHF accelerates the healing process of affected tissues and minimizes the likelihood of complications.
  2. Pathologies of the gastrointestinal tract (pancreatitis, ulcers, enteritis, cholecystitis, viral hepatitis) – the procedure reduces pain, has an anti-inflammatory effect, accelerates tissue healing. In addition, UHF improves intestinal motility.
  3. Disorders in the work of the nervous system (plaksitis, neuritis, encephalitis, migraine, sciatica) – due to the acceleration of blood circulation, tissues are restored faster. At the same time, muscle spasms are reduced.
  4. Eye diseases (blepharitis, uveitis, glaucoma, and so on) – this procedure reduces allergies and has an anti-inflammatory effect. Also, under its influence, phagocytosis increases, due to which the restoration of damaged tissues occurs faster.
  5. Diseases of the cardiovascular system (hypertension, cerebrovascular accident, varicose veins) – after UHF, tissue swelling decreases, muscle tone decreases and, as a result, blood pressure normalizes.
  6. Skin diseases (acne, eczema, psoriasis, phlegmon, herpes) – this procedure enhances the body’s defense system, accelerates the process of epithelization and has a desensitizing effect.
  7. dental problems (alveolitis, gingivitis, periodontitis, injuries) – UHF increases blood circulation in the gums and reduces pain. In addition, this procedure inhibits the viability of pathogenic bacteria.
  8. Pathologies of the musculoskeletal system (dislocations, fractures, bruises, sciatica, and so on) – during this physiotherapy, the tissues are heated, due to which the vessels expand and, as a result, blood circulation increases. This improves cell nutrition and accelerates their regeneration.
  9. Rehabilitation in the postoperative period – the procedure reduces the risk of tissue infection and complications. In addition, it accelerates the regeneration process, anesthetizes and strengthens the body’s defenses.

UHF – contraindications

In some cases, this procedure cannot be carried out. UHF treatment is prohibited under the following circumstances:

  • pregnancy;
  • blood clotting disorder;
  • the presence of malignant neoplasms;
  • hypertension of the third stage;
  • fever;
  • the presence of a built-in pacemaker;
  • angina;
  • myocardial infarction;
  • severe blockage of the veins.

Carrying out UHF therapy

One of the features of this procedure is that it is performed on wooden furniture. During its implementation, the patient either sits or lies (it all depends on which part of the body needs rehabilitation). Since the device acts through clothing, it is not necessary to undress. UHF can be performed in the following ways:

  1. Longitudinal – during the procedure, electrodes are applied only to the affected area. With this method of exposure, the electromagnetic field does not penetrate deeply, so this procedure is more often used in the fight against superficial diseases. The optimal distance between the body and the electrode is up to 1 cm.
  2. transverse – such physiotherapy provides for a bilateral effect (one plate is applied to the affected area of ​​the body, and the second – from the opposite side). With this arrangement, an extensive electromagnetic field is formed. The optimal distance between the patient’s body and the electrode is less than 2 cm.

The UHF treatment procedure is performed as follows:

  1. The specialist selects the electrodes of the optimal shape for the patient.
  2. Installs them in special holders.
  3. Wipes the plates with an alcohol-containing solution and applies them to the problem area of ​​the patient.
  4. After installing the electrodes, electricity of a certain power is supplied. The value of this indicator is set using a special regulator.

UHF – range:

  1. Thermal dose – its power varies from 100 to 150 watts. During this procedure, you feel warm. This therapy has a provocative goal.
  2. Oligothermic dosage – power ranges from 40-100 watts. The patient experiences a barely perceptible warmth. This UHF at home improves blood circulation and normalizes metabolism.
  3. Athermic dose – its power varies between 15-40 watts. The procedure has an anti-inflammatory effect.

This therapy is prescribed for both adults and children. If the procedure is assigned to babies, the following principles are followed when performing it:

  1. The child must be at least 5 days old.
  2. For children under 7 years old, the recommended power is 30 watts, and at school age – 40 watts.
  3. To protect the child from burns, a bandage substrate is installed between the electrodes and the baby’s body.

UHF for sinusitis

UHF with sinusitis

The procedure is often carried out daily. Its duration is up to 15 minutes. The treatment course for adults is represented by 15 sessions, and for children – 12 procedures. UHF of the nose provides for exposure to heat of various capacities:

  • with a purulent process – a cold stream;
  • in the non-purulent period – weak heat;
  • if the patient has a chronic lesion, the power is increased.

UHF for bronchitis

uhf for bronchitis

Under the influence of heat flow, the outflow of blood and lymph increases. The result is reduced inflammation and faster tissue repair. UHF of the chest with bronchitis is recommended to be carried out 1-2 times a day. The procedure can take 20 minutes. The duration of therapy directly depends on the intensity with which the disease proceeds. More often appoint 6-10 procedures.

UHF for otitis media

The procedure gives good results. The UHF algorithm is the same as in the treatment of other diseases. A magnetic field of various intensities can be used:

  • weak – reduce inflammation;
  • medium – will improve metabolic processes;
  • strong – will provide a provocative effect.

UHF tooth

UHF tooth

With such therapy, the power used should not exceed 40 watts. UHF in dentistry is short in time: the session does not exceed 10 minutes. The course depends on the disease:

  • with inflammatory processes in an acute form – 4-5 procedures;
  • in case of osteomyelitis – 8-10 sessions.

UHF – pros and cons

Such physical therapy can be helpful or cause serious harm. The decisive factor is whether UHF of the chest or other part of the body is done by a specialist or not. Self-medication is unacceptable. If the power calculation is incorrect, serious complications can arise. The negative consequences of UHF in physiotherapy are as follows:

  • thermal damage to tissues due to contact with electrodes;
  • bleeding caused by hyperthermia;
  • electric shock (occurs in case of contact with bare areas of the device);
  • scars occur.
