METHOD FOR SKIN ELECTRIC STIMULATION OF SPINAL CORD Russian patent published in 2015 - IPC A61N1/32 

FIELD: medicine.

SUBSTANCE: spinal cord segments of the patient lying on his/her side with his/her legs suspended in a swing frame is exposed to a rectangular bipolar electric square-wave stimulus sequence at frequency 5-40 Hz, duration 0.5-1 ms and carrier frequency 10 kHz. The exposure covers the segments arranged above the spine directly between spinous processes of the spinal cord, and the segments arranged symmetrically from the right and left from the spinal column, above the spinal roots. The stimuli are supplied in the preset order. Depending on the stimulated spinal cord segment, stimuli amplitude is specified within the range of 40-250 mA, whereas a pulse phase shift in the stimulus train is within the range of 0.1-0.5 ms. That is ensured by using a device, which comprises matrixes in the form of electrodes, an electric stimulus former, a control unit, a microcontroller with software, a signal former, a current amplitude measuring unit at the electrode input and an indication unit of the required parameters.

EFFECT: invention enables controlling compulsory leg motions and causing coordinated footsteps.
