Claim 7:
8. A system for treating pain of a patient via electrical stimulation of a portion of a dorsal root ganglion of the patient, the system comprising:
a lead comprising at least one electrode disposed on a distal end; and
a pulse generator configured to provide a plurality of stimulating signals to the at least one electrode to stimulate the dorsal root ganglion; and
a programmer device operable to determine optimal therapy parameters to treat the pain of the patient, wherein the programmer device is configured to:
perform mapping operations to identify sets of parameters that activate distinct sub-dermatome regions associated with the dorsal root ganglion,
provide a current step size that is selectable from a plurality of values, wherein the plurality of values includes at least one current step size that is sufficiently small to permit identification of sub-dermatomal stimulation.
