SYSTEM AND METHOD FOR DELIVERING SUB-THRESHOLD AND SUPER-THRESHOLD THERAPY TO A PATIENT
First Claim
1. A neuromodulation system, comprising:
- modulation output circuitry configured to deliver therapeutic electrical energy including therapeutic sub-threshold electrical energy and therapeutic a super-threshold electrical energy, the sub-threshold electrical energy being below a patient-perception threshold and the super-threshold electrical energy being above the patient-perception threshold, the patient-perception threshold being a boundary below which a patient does not sense delivery of the electrical energy and above which the patient does sense delivery of the electrical energy; and
control circuitry configured to control the modulation output circuitry to deliver the therapeutic electrical energy using alternating cycles of the sub-threshold electrical energy below the patient-perception threshold and the super-threshold electrical energy above the patient-perception threshold.

Abstract
A neuromodulation system includes modulation output circuitry and control circuitry. The modulation output circuitry may be configured to deliver therapeutic electrical energy including therapeutic sub-threshold electrical energy and therapeutic a super-threshold electrical energy. The sub-threshold electrical energy is below a patient-perception threshold and the super-threshold electrical energy is above the patient-perception threshold. The patient-perception threshold is a boundary below which a patient does not sense delivery of the electrical energy and above which the patient does sense delivery of the electrical energy. The control circuitry is configured to control the modulation output circuitry to deliver the therapeutic electrical energy using alternating cycles of the sub-threshold electrical energy below the patient-perception threshold and the super-threshold electrical energy above the patient-perception-threshold.
