Abstract

A model of an implantable lead is provided via a graphical user interface. The implantable lead is configured to deliver electrical stimulation to a patient via a plurality of electrodes located on the implantable lead. The graphical user interface also provides a plurality of predefined electrode activation patterns that include a coarse pattern and a refined pattern. The coarse pattern corresponds to a first group of electrodes located in a first region of the implantable lead. The refined pattern corresponds to a second group of electrodes located in a second region of the implantable lead. The second region is smaller than, and is a subsection of, the first region. A coarse testing process is performed by selectively activating the first group of electrodes belonging to the coarse pattern. Thereafter, a refined testing process is performed by selectively activating the second group of electrodes belonging to the refined pattern.
