1. A method for screening a plurality of stimulation therapy programs for delivery of deep brain stimulation (DBS) by an implantable medical device (IMD) using an external programming device, the method comprising: for each of a plurality of electrode combinations including at least one electrode on a DBS lead coupled to the IMD, controlling the IMD, with the external programming device, to incrementally ramp up an amplitude of DBS delivered via the electrode combination through a plurality of amplitude values; presenting, via the external programming device, a user interface configured to receive user input that logs at least one of a beneficial effect or an adverse effect at each of the plurality of amplitude values for each of the plurality of electrode combinations, wherein the user interface enables the user to enter one or both of a rating value from a predetermined scale of rating values or a textual description of the beneficial effects and adverse effects; storing, with the external programming device, the rating values or textual descriptions of the beneficial or adverse effects in association with the electrode combinations and amplitude values for which beneficial or adverse effects occurred; and displaying, via the external programming device, the electrode combinations for which DBS amplitude has been incrementally ramped up in conjunction with amplitude values, and associated rating values and textual descriptions.
