System and method for delivering modulated sub-threshold therapy to a patient
First Claim
1. A method of providing therapy to a patient, comprising:
- providing a sub-threshold therapy to the patient, including delivering electrical energy to tissue of the patient in accordance with at least one modulation parameter at a sub-threshold level such that the delivered electrical energy is not perceived by the patient but is therapeutically effective for the sub-threshold therapy; and
pseudo-randomly varying a value of the at least one modulation parameter based on a previous value of the at least one modulation parameter, wherein the at least one modulation parameter is pseudo-randomly varied within a limited range to continually maintain the delivered electrical energy at the sub-threshold level in which the delivered electrical energy is therapeutically effective for the sub-threshold therapy and is not perceived by the patient.

Abstract
A neuromodulation system configured for providing sub-threshold neuromodulation therapy to a patient. The neuromodulation system comprises a plurality of electrical terminals configured for being respectively coupled to a plurality of electrodes, modulation output circuitry configured for delivering electrical energy to the electrical terminals in accordance with at least one modulation parameter, thereby providing therapy to the patient at a sub-threshold level and control circuitry configured for controlling the modulation output circuitry in a manner that pseudo-randomly varies a value of the at least one modulation parameter based on a previous value of the at least one modulation parameter, such that the delivered electrical energy is continually maintained at the sub-threshold level.
