Abstract: FIELD: medical engineering. 
     SUBSTANCE: device has n channels where n is even number. Each channel has stimulating signal generator and stimulating signal shaper. The stimulating signal generator has delay unit, unit for blanking coincident signals, packet envelope shaper and pulse packet oscillator. The stimulating signal shaper has power amplifier and unit containing the first starting cell and the first digital display. Unit for determining mean step is introduced into each stimulating signal generator. The unit output is connected to information inputs of delay unit and of stimulating signal shaper. The first input is combined with delay unit input and is called stimulating signal generator Start input. The second one is combined with corresponding delay unit input and packet envelope shaper and is called Set Zero input of the stimulating signal generator. Output of the unit for blanking coincident signals is connected to packet envelope shaper input. I-th stimulating signal generator delay unit output (I=1...n) is connected to i-th input of the unit for blanking coincident signals and serves as output of delayed signals. Inputs of the unit for blanking coincident signals (with the exception of the i-th one) form a group of delayed signals inputs of the stimulating signals generator. Information outputs of the delay unit and of the packet envelope shaper are the first and the second information outputs of the stimulating signal generator, respectively. Packet envelope shaper output is connected to packet envelope generator start input which output is signal output of the stimulating signal generator.  
     Packet envelope shaper output is processes visualization output of the stimulating signals generator. Each stimulating signal shaper additionally has in series connected attenuator and output transformer symmetric output of which is shaper signal output. Inverter has input connected to power amplifier output. Switch is available between outputs from the power amplifier, inverter and attenuator input. Power amplifier input serves as signal input of the shaper. the second digital display, clock pulse oscillator, the first switch are introduced into movement corrector. The first input of the first switch is connected to clock pulse oscillator output, the output being connected to combined Start inputs of stimulating signals generators having visualization input with its signal inputs being connected to stimulating signals generators processes visualization outputs. The second switch has output connected to synchronizing output of visualization unit input. The third switch has the first and the second outputs connected to the second and the third inputs of the first switch, respectively. Three start transducers make start transducers set with the available one with the first, the second, the third and the fourth outputs are connected to the second and the third switch inputs. The fourth and the fifth switch are available between the first and the second information outputs of stimulating signals generators, respectively. Output of the delayed signals of i-th stimulating signals generator (I=1...n) is connected to inputs of delayed signals group from the remaining stimulating signals generators. Set Zero inputs of the stimulating signals generators are joined together forming movement corrector Set Zero input. 
     EFFECT: wide range of functional applications; enhanced effectiveness in treating patient possessing heavy locomotor apparatus disorders both in rest state and in moving.
