A device for neurostimulation includes a pulse generator for generating current having pulses and at least one first pair of electrodes connected to the pulse generator. 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 are controlled by the therapy strength configuration, 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. The association between therapy strength parameter and current parameter configurations uniquely adjusts the current parameter configurations based on paresthesia or paresthesia-free intent, when neurostimulation is performed using parameter configurations. Particularly, the current parameter configurations include parameters such as pulse trains, pulse frequencies, duty cycling, and amplitudes of the current.
