Abstract:
1. A neurostimulation system for use with an implantable neurostimulation lead, the neurostimulation system comprising: at least one stimulation source; and circuitry configured for taking a baseline evoked potential measurement by prompting the at least one stimulation source to convey a first stimulation pulse to tissue with the neurostimulation lead while at a baseline location, and measuring an evoked potential resulting from the conveyance of the first stimulation pulse to the tissue, configured for taking a subsequent evoked potential measurement by prompting the at least one stimulation source to convey a second stimulation pulse to tissue with the neurostimulation lead at a subsequent time after the neurostimulation lead has migrated from the baseline location, and measuring an evoked potential resulting from the conveyance of the second stimulation pulse to the tissue, and configured for determining a magnitude that the neurostimulation lead has migrated from the baseline position by comparing the subsequent evoked potential measurement to the baseline evoked potential measurement.
