11. An electrical stimulation device comprising:
a lead adapted for percutaneous insertion below skin of an animal body with back pain consisting of a multi-strand wire member formed into a helix from a plurality of stainless steel strands, with a layer of insulation partially covering an exterior of the lead;
an electrode formed from a de-insulated portion of the lead; and
an external pulse generator operatively coupled with the lead, wherein the external pulse generator delivers an intensity of electrical stimulation though the electrode for a prescribed period of time wherein the electrical stimulation is configured to activate motor axons of at least one muscle in a back of the animal body causing muscle contraction of the at least one muscle to relive pain and wherein the electrical stimulation is configured to prevent activation of painful sensory axons.
