1. A method, comprising:
positioning at least one lead to place a plurality of electrodes in proximity to a nerve root;
determining a therapeutic window for each of the plurality of electrodes, wherein for each of the plurality of electrodes determining the therapeutic window includes:
applying stimulation;
determining a first stimulation threshold for the applied stimulation to cause a first physiological effect;
determining a second stimulation threshold for the applied stimulation to cause a second physiological effect; and
determining a difference between the first stimulation threshold and the second stimulation threshold, wherein the difference is the therapeutic window;
determining at least one electrode with a minimum value for the therapeutic window; and
suggesting at least one electrode, based on the determined at least one electrode with the minimum value, to be used to stimulate the nerve root.
