Patent ID: 8923976

Claim:
A method for delivering electrical stimulation to a patient, the method comprising: receiving, by at least one processor, a spatial electrode movement pattern that defines a sequence with which first electrical stimulation is moved between a plurality of electrodes implanted within the patient; delivering the first electrical stimulation having a first stimulation intensity to the patient with electrodes of the plurality of electrodes selected according to the spatial electrode movement pattern for each step of the sequence, wherein the first electrical stimulation is moved, for each step of the sequence, between the plurality of electrodes according to the spatial electrode movement pattern; delivering, concurrently with the first electrical stimulation and during each step of the sequence, a second electrical stimulation having a second stimulation intensity to the patient with electrodes of the plurality of electrodes unselected by the spatial electrode movement pattern, the electrodes selected by the spatial electrode movement pattern and the electrodes unselected by the spatial electrode movement pattern comprising all of the plurality of electrodes, wherein the first stimulation intensity is greater than the second stimulation intensity; and repeating the spatial electrode movement pattern when delivering the first electrical stimulation and the second electrical stimulation to the patient.
