1. A method of monitoring a neurostimulation lead having a plurality of electrodes implanted within a patient, the method comprising:

  • providing a plurality of sets of estimated electrical parameter data, each set corresponding to a predetermined relative position of the neurostimulation lead;

    transmitting electrical energy to or from the electrodes;

    measuring electrical parameter data in response to the transmitted electrical energy;

    comparing the measured electrical parameter data with the estimated electrical parameter data of each of the sets; and

    determining a position of the neurostimulation lead based on the comparison.
