Combined high and low frequency stimulation therapy

In some examples, the disclosure relates to system, devices, and techniques for delivering electrical stimulation therapy to treat patient disorders characterized by overactive nerve activity. In one example, the stimulation therapy may include high frequency and low frequency stimulation. The high frequency stimulation may be configured to substantially block overactive pathological nerve activity of the patient and the combination of the high frequency and low frequency simulation may be configured to result in nerve activity that mimics non-pathological nerve activity.
