Abstract

A system and method for selecting leadwire stimulation parameters includes a processor iteratively performing, for each of a plurality of values for a particular stimulation parameter, each value corresponding to a respective current field: (a) shifting the current field longitudinally and/or rotationally to a respective plurality of locations about the leadwire; and (b) for each of the respective plurality of locations, obtaining clinical effect information regarding a respective stimulation of the patient tissue produced by the respective current field at the respective location; and displaying a graph plotting the clinical effect information against values for the particular stimulation parameter and locations about the leadwire, and/or based on the obtained clinical effect information, identifying an optimal combination of a selected value for the particular stimulation parameter and selected location about the leadwire at which to perform a stimulation using the selected value.

for each of a plurality of values for a particular stimulation parameter, each value corresponding to a respective current field produced by a respective combination of one or more of the electrodes of the leadwire, obtaining, by a computer processor, clinical effect information regarding a respective stimulation of the patient tissue produced by the respective current field;
displaying a graph plotting the obtained clinical effect information as respective data points, wherein each data point is characterized by an angle of rotation and a radius from a center of the graph, wherein the radius corresponds to the value for the particular stimulation parameter associated with the data point and the angle of rotation corresponds to a direction characterizing the current field associated with the data point;
receiving a user selection of a point on the graph, wherein the point corresponds to a first value of the particular stimulation parameter and a first combination of one or more of the electrodes of the leadwire;
