Description

 The invention relates to medicine and can be used in the practice of treating pain syndromes.

 A known method of reflex anesthesia by exposure to the peripheral and central nervous system by pulsed currents. It is also known a device that implements the specified method.

 A disadvantage of the known method and device is a purely symptomatic short analgesic effect.

 The aim of the invention is to lengthen the analgesic effect and shorten the course of treatment.

 This is achieved by the fact that according to the method of stopping pain syndromes in diseases of the musculoskeletal system, the effect is carried out by short-pulse bipolar currents with a repetition rate of 6-120 Hz, a duration of a negative pulse of the output current of 20-500 μs, an amplitude of up to 50 mA, a rectangular shape, a positive pulse of exponential forms. In this case, the active electrode is installed in the projection area on the skin surface of maximum pain, and the passive electrode is installed in the zone of sigmentation below the painful area, while additionally acting on the projection area of maximum pain is a pulsed low-frequency electromagnetic field (INEMP) with a pulse repetition rate of 20- 120 Hz and field strength in the treatment zone of 0.01-10 V / cm.

 Regarding the device, the technical result is achieved by the fact that the device for the relief of pain syndromes from diseases of the musculoskeletal system, containing an analgesic pain stimulator with two elastic electrodes connected to it made of conductive rubber, additionally includes a pulse low-frequency voltage generator and a stimulation element connected to it, representing a flat elastic dielectric insulated ring, with one of the elastic electro s or more elastic dielectrically isolated wafer defined between elastic electrodes.

 In FIG. 1 shows a block diagram of a device with a stimulation element made in the form of an elastic dielectric insulated ring; figure 2 is a block diagram of a device with a stimulation element made in the form of several dielectric insulated plates; figure 3 relative position of the stimulation element in the form of a ring and electrodes on the patient's body; figure 4 relative position of the stimulation element in the form of plates and electrodes on the limbs of the patient.

 The method is as follows.

 The patient is strengthened with an active electrode on the skin in the area of projection of maximum pain, a passive electrode connected to the positive pole of the electric stimulator is placed above or below the painful area in close proximity to the active one (Fig. 3).

 In radicular syndromes, a system of capacitor plates is used in the form of longitudinal plates mounted on one side of the body surface, the lateral surface of the electrodes and plates being parallel to the nerve fiber, and the nerve fiber itself must be between the electrodes under one of the capacitor plates (Fig. 4).

 The selection of frequencies of electrical stimulation is carried out individually. Treatment begins with exposure to a current frequency of 50-60 imp / s. In the future, the frequency of electrical stimulation is reduced to 10-15 imp / s. The current strength is set according to the patient's sensation of a pleasant vibration. Then include the source of INEMP. The course of treatment begins with frequencies of 120 Hz and by the end of the course of treatment is reduced to 20 Hz. The intensity of INEMP is determined by the severity of the pain syndrome. At the beginning of the course, the field strength in the therapy zone is 0.1 V / cm. By the end of the course, it rises to 2-10 V / cm. The magnitude of the field strength in the therapy zone is determined by the amplitude of the pulses supplied to the stimulation element and the thickness of the dielectric between the electrode and the skin surface.

 The duration of one procedure is 5-10 minutes. The number of procedures in the course of treatment is 5-7. At the end of the procedure, the INEMP source is turned off, then the electric stimulator is turned off.

 A device for stopping pain syndromes in diseases of the musculoskeletal system (Fig. 1) contains an analgesic stimulator 1 with an active electrode 2 connected to its negative terminal and a passive electrode 3 to its positive terminal, an impulse low-frequency voltage generator 4 with a stimulation element connected to it, representing a flat elastic ring 5, insulated by a dielectric 6, with an elastic electrode 2 installed inside it, in contact with the surface of the skin 7, or representing oh several elastic plates 8, insulated by a dielectric 6 with electrodes 2 and 3 installed between them, mounted on the surface of the skin 7 (figure 2).

 The device operates as follows.

 When localizing pain in the shoulder-scapular, lumbosacral region (Fig. 3), a flat elastic dielectric insulated ring 5 with an active electrode 2 installed inside it is installed on the skin surface with maximum pain or above it within that part of the segmental innervation zone. The passive electrode is installed in close proximity to the active one. The electrodes on the patient's skin are fixed with a band-aid.

 When pain is localized in the limbs of the musculoskeletal system (Fig. 4), several elastic dielectric insulated plates 8 are installed with electrodes 2, 3 installed between them on the skin surface with maximum pain and the electrodes are crimped in the form of a half ring and fixed on the patient’s skin with adhesive plaster.

 Then turn on the pain stimulator in accordance with the instructions for use of the apparatus "Electronics EPB-50-01". Turn on the generator 4 pulsed low-frequency voltage and carry out the procedure.

 PRI me R 1. Patient K. 41 years old, was admitted with a pronounced pain syndrome in the thoracic spine with irradiation along the intercostal spaces. Diagnosis: osteochondrosis, discogenic sciatica. Pain was practically not stopped by analgesics and antispasmodics. Only drugs brought the patient relief. Physiotherapy with known commonly used methods increased the patient's suffering.

 Objectively: a patient of average height, normal nutrition. The boundaries of the heart are within normal limits. The tones are slightly muffled. Weak systolic murmur at the apex of PS-64, AD-110/70. Weakened, shallow breathing. The abdomen is slightly tense (reflexively). Diuresis is normal.

 Local status. Muscles in the thoracic region are tense; He cannot move and serve himself. At the slightest movement, a change in body position, the pain sharply intensifies to intolerant. The patient underwent a treatment according to the described treatment technique. After the 1st procedure (5 min), the pain decreased, the effect lasted about 10 hours. After the 3rd procedure (7 min), the decrease in the intensity of the pain syndrome lasted about 12 hours. The patient fell asleep without sedative medication. After the 7th procedure (8 min), she refused the injection of analgesics. After the 10th procedure (10 min), the pain almost stopped. The patient began to move independently and prepare for discharge.
