1. A system comprising:

  • stimulation circuitry that delivers stimulation to a patient via electrodes;

    impedance measurement circuitry that periodically measures an impedance associated with the electrodes;

    a user interface; and

    a processor that receives at least one feedback indicator that indicates a perceived degree of intensity of the stimulation at each of a plurality of measured impedance values via the user interface, and determines a patient-specific relationship between a stimulation parameter and impedance based on the measured impedance values and the feedback indicators.
