Abstract:
1. A method of stimulating one or more dorsal column fibers associated with a sub-region of a patient's bodily region, the method comprising: selecting at least one active electrode combination of a paddle structure having a plurality of electrodes, the paddle structure having first and second side edges and distal and proximal ends with the proximal end being continuously arcuate shaped and extending between the first and second edges in a tapered manner, the plurality of electrodes disposed in at least five mutually adjacent columns and at least two mutually adjacent rows such that the one active electrode combination has an electric field of a resolution to deliver perceived stimulation to a first set of one or more dorsal column fibers of a first sub-region of the patient's bodily region without causing perceived stimulation in a second sub-region associated with a second set of one or more dorsal column fibers, wherein the first set of dorsal column fibers are in an adjacent fasciculus to the second set of dorsal column fibers and the bodily region is selected from the group consisting of upper extremities, lower extremities, and trunk of the patient wherein the active electrode combination is moved laterally such that the electric field migrates across the dorsal column of the patient providing perceived stimulation of sub-region of a patient's bodily region, wherein the sub-region is associated with the lateral segmentation of the one or more fasciculus of the patient's dorsal column.
