The present invention relates to a device for neurostimulation, with a pulse generator capable of generating current comprising pulses, and at least a first pair of electrodes connected to the pulse generator, wherein the device provides a user-programmable therapy strength parameter configuration and at least two current parameter configurations for neurostimulation stored in the pulse generator, the current parameter configurations being controlled by the therapy strength configuration, and wherein at least one of the current parameter configurations is associated with a level of paresthesia sensation of a patient and at least one of the current parameter configurations is associated with a paresthesia-free therapy for the patient, wherein the association between the therapy strength parameter and the current parameter configurations uniquely adjusts the current parameter configurations based on their paresthesia or paresthesia-free intent, and when the neurostimulation is performed using said parameter configurations. Particularly, the current parameter configurations comprise parameters such as pulse trains, pulse frequencies, duty cycling, and amplitudes of the current.
