Abstract
The invention is directed to a technique for rating neuromodulation efficacy based on evaluation of the response of the patient to sensory stimuli with and without delivery of neuromodulation therapy. In addition, the invention may provide a system capable of delivering sensory stimuli on a quantitative basis in a coordinated manner with delivery of neuromodulation therapy. A device programmer may provide a platform for controlling delivery of the sensory stimuli, delivery of neuromodulation therapy, and generation of rating information for neuromodulation efficacy based on patient sensory response to the stimuli. In operation, the programmer controls application of selected sensory stimuli to the patient'"'"'s body and records the patient'"'"'s verbal or physiological responses to the stimuli. This invention can be used to be a diagnostic or prognostic test that a given neuromodulation therapy, such as neurostimulation or drug delivery, is and will be successful.
