METHOD FOR CRANIOSPINAL ELECTROMAGNET THERAPY AND DEVICE FOR ITS REALIZATION Russian patent published in 2005 - IPC

FIELD: medicine, neurology, physiotherapy.

SUBSTANCE: contact action by electric current on the region of the forehead and mastoid processes and contact action by magnetic field along the vertebral column are performed simultaneously. The action on the region of the forehead and mastoid processes is effected by direct current, 1 to 7 mA strong, modulated by low-frequency square pulses. A frequency within 0.5 to 550 Hz causing a change of the electrodermal resistance in the biologically active points is assigned as operating frequency. Action along the vertebras is effected by a pulse field with amplitude of magnetic induction up to 1 T and pulse frequency up to 100 Hz. The dominant frequency by the results of the electroencephalography is assigned as operating frequency, and the time of action is set to be equal to 35+-5 min. The device has an electrostimulator unit, whose output is made for connection to the electrodes in the patient's circuit, and a magnetic field forming unit with a solenoid, with a magnetic field forming unit with a solenoid, with power units each. The electrostimulator unit has a transducer of a series-connected master oscillator, transformer-coupled amplifier and a rectifier. The rectifier output is connected to the input of the first gate and made as the output of the electrostimulator unit. The device has a pulse shaper, whose output is connected to the input of the first gate, an output current level controller made for starting from the master oscillator, and whose output via the second gate and a ripple filter is connected to the transformer-coupled amplifier and the adder. The adder output is connected to the output of the first gate and the current meter. The magnetic field forming unit has a capacitor connected to the solenoid winding and via the switching unit - to the power unit. The switching unit is connected to the output of the control unit. The input of the pulse shaper of the electrostimulator unit and the input of the control unit of the magnetic field forming unit are made for connection to a personal computer via galvanic isolators.

EFFECT: reduced degree of disintegration in the structures of the limbic-reticular complex producing an optimizing action on the neurodynamics.
