A system for improving neural communication impairment of a vertebrate being and affecting motor activity of a peripheral body part of the being, the system comprising: a first signal-providing component configured to provide peripheral stimulation signal pulses at a peripheral body part of a vertebrate being for stimulating responsive peripheral signal pulses; a second signal-providing component configured to provide a motor cortex stimulation signal pulse to a motor cortex area of the being for stimulating a responsive motor cortex action potential signal pulse; a continuous-level DC signal-providing component configured to provide a substantially continuous direct current spinal stimulation signal at a neural spinal junction of the being; and a controller component configured to control timing of the peripheral stimulation signal pulses (P1, P2) and the motor cortex stimulation signal pulse; the timing of the peripheral stimulation signal pulses and the motor cortex stimulation signal pulse being controlled such that said responsive peripheral signal from the peripheral body part and said responsive motor signal from the motor cortex area are substantially simultaneously present at the neural spinal junction when the neural spinal junction is stimulated by the spinal stimulation signal; characterised in that the controller component is configured to control the timing of the pulsed signals such that several peripheral pulses (P1, P2) occur per cortical pulse, wherein the controller component is further configured to provide the direct current spinal stimulation signal at the neural spinal junction before the pulses of the pulsed peripheral stimulation signals (P1, P2) and pulsed motor cortex stimulation signal are applied, and subsequently to provide a first pulse as a peripheral stimulation signal to a nerve at a muscle of interest, and provide, after a first time delay after providing the first pulse, a second pulse of the peripheral stimulation signal to the nerve at the muscle, and provide, after a second time delay after providing the first and second pulses, a pulse of the pulsed motor cortex stimulation signal, the first time delay and the second time delay being selected wherein the backward motor signal from the stimulated nerve for the muscle and the pulsed motor signal from the motor cortex are enabled to be substantially simultaneously present at said neural spinal junction when the neural spinal junction is being stimulated by the direct current spinal stimulation signal. a first signal-providing component configured to provide peripheral stimulation signal pulses at a peripheral body part of a vertebrate being for stimulating responsive peripheral signal pulses; a second signal-providing component configured to provide a motor cortex stimulation signal pulse to a motor cortex area of the being for stimulating a responsive motor cortex action potential signal pulse; a continuous-level DC signal-providing component configured to provide a substantially continuous direct current spinal stimulation signal at a neural spinal junction of the being; and a controller component configured to control timing of the peripheral stimulation signal pulses (P1, P2) and the motor cortex stimulation signal pulse; the timing of the peripheral stimulation signal pulses and the motor cortex stimulation signal pulse being controlled such that said responsive peripheral signal from the peripheral body part and said responsive motor signal from the motor cortex area are substantially simultaneously present at the neural spinal junction when the neural spinal junction is stimulated by the spinal stimulation signal; characterised in that the controller component is configured to control the timing of the pulsed signals such that several peripheral pulses (P1, P2) occur per cortical pulse, wherein the controller component is further configured to provide the direct current spinal stimulation signal at the neural spinal junction before the pulses of the pulsed peripheral stimulation signals (P1, P2) and pulsed motor cortex stimulation signal are applied, and subsequently to provide a first pulse as a peripheral stimulation signal to a nerve at a muscle of interest, and provide, after a first time delay after providing the first pulse, a second pulse of the peripheral stimulation signal to the nerve at the muscle, and provide, after a second time delay after providing the first and second pulses, a pulse of the pulsed motor cortex stimulation signal, the first time delay and the second time delay being selected wherein the backward motor signal from the stimulated nerve for the muscle and the pulsed motor signal from the motor cortex are enabled to be substantially simultaneously present at said neural spinal junction when the neural spinal junction is being stimulated by the direct current spinal stimulation signal.
