Abstract: In one example, a computing device includes a memory to store data representative of an implant location of a lead in a patient, wherein the lead comprises a plurality of electrodes, and one or more processors configured to determine, based on the implant location, probabilities of effectiveness of electrical stimulation delivered via each of the electrodes, and present a visual representation of the determined probabilities. For instance, the representation of the determined probabilities may be displayed in conjunction with visual representations of the lead and the electrodes. The electrodes may comprise sectors of rings along the lead. In this manner, a clinician or other user of the programmer device may quickly determine electrodes that will most probabilistically deliver effective therapy via electrical stimulation.
