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 a user interface via the external programming device that enables a user to log at least one of a beneficial effect or an adverse effect at each of the amplitude values, 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 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.
