1. A stimulation system comprising:
a coiled fine wire lead having a thickness and a diameter configured for percutaneous insertion into a portion of a body;
a plurality of electrodes each formed integrally on the coiled fine wire lead, wherein the electrodes are spaced apart from one another with an insulated portion positioned between at least two of the plurality of electrodes; and
an electrical stimulation device operatively coupled to the coiled fine wire lead and configured to apply electrical stimulation through the plurality of electrodes, wherein the electrodes are configured to be positioned in tissue a distance spaced from (i) at least one of a Type Ia and Ib afferent nerve fibers and (ii) at least one of Type III and Type IV nerve fibers and wherein the electrical stimulation selectively activates at least one of the Type Ia and Ib afferent nerve fibers while minimizing recruitment of activation of the at least one of the Type III and Type IV nerve fibers because the plurality of electrodes are spaced the distance from the at least one of a Type Ia and Ib afferent nerve fibers and the at least one of Type III and Type IV nerve fibers.
