1. A neuromodulation system comprising:
a stimulation generator configured to deliver symmetrical electrical stimulation through a plurality of stimulation electrodes, the plurality of stimulation electrodes comprising at least two of a first electrode, a second electrode, at least one segment electrode of a first group of segmented electrodes, or at least one segment electrode of a second group of segmented electrodes, wherein the symmetrical electrical stimulation comprises electrical stimulation of a same amplitude from each stimulation electrode of a respective pair of stimulation electrodes;
a sensing channel configured to sense a response to the symmetrical electrical stimulation through a plurality of sense electrodes, the plurality of sense electrodes comprising at least two of the first electrode, the second electrode, at least one other segment electrode of the first group of segmented electrodes, or at least one other segment electrode of the second group of segmented electrodes, each of the plurality of sense electrodes being different than each of the plurality of stimulation electrodes; and
processing circuitry configured to:
control the stimulation generator to deliver the symmetrical electrical stimulation;
determine a response to the symmetrical electrical stimulation via the sensing channel; and
adjust at least one stimulation parameter of the symmetrical electrical stimulation based on the sensed response.
