The disclosure provides techniques for parameter-directed shifting of electrical stimulation electrode combinations having substantially similar electrode patterns. An external programmer permits a user to shift electrode combinations along the length of a lead or leads. The external programmer accepts parameter-directed shift input and causes an electrical stimulator to shift electrode combinations as indicated. The external programmer may present an electrode combination as a parameter that can be adjusted or selected to shift the electrode combination along the length of a lead. An electrode combination may be presented as a value that can be incremented, decremented, or otherwise adjusted to indicate a shift in a desired direction. An external programmer that permits a patient or other user to shift electrode combinations in a manner similar to adjustments of other parameters may enable the patient to maintain or improve therapeutic efficacy. |
