A method of programming an implantable medical device (IMD) configured to provide electrical stimulation via a plurality of stimulation vectors during delivery of the electrical stimulation of a plurality of pulse widths to a neural target. The method may comprise comparing strength-duration curve data for the plurality of stimulation vectors to one another, the strength-duration curve data representing, for respective pulse widths and stimulation vectors, a corresponding stimulation strength that evokes a physiological response associated with the neural target. The method may comprise selecting at least one stimulation vector of the plurality of stimulation vectors based on the comparison of the strength-duration curve data for the plurality of stimulation vectors. The method may comprise programming, in response to the selection, the IMD to deliver the electrical stimulation to the neural target via the selected at least one stimulation vector.
