The present invention relates to a neuromodulation/neurostimulation system (10) for the treatment of spasticity in a mammal, said system (10) comprising: - at least one control unit (12) configured and arranged to provide stimulation data, and - at least one stimulation unit (14), operatively connected to the at least one control unit (12), said at least one stimulation unit (14) being configured and arranged to deliver epidural electrical stimulation to the spinal cord of said mammal, according to said stimulation data, wherein the at least one stimulation unit (14) includes a biocompatible implantable lead (18) configured and arranged to cover at least a portion of the spinal cord of said mammal to deliver epidural electrical stimulation to the dorsal roots innervating the spastic muscles to target neuronal circuitry responsible for spastic episodes.
