1. An electrical stimulation device comprising:
a monopolar electrode adapted for insertion within an animal body;
a percutaneous lead operatively coupled with the monopolar electrode; and
an external pulse generator operatively coupled with the electrode through the percutaneous lead, wherein the pulse generator delivers electrical stimulation to peripheral nerves generating neurally encoded signals in afferent nerve fibers to evoke changes in central processing of pain without stimulation of muscles at a level necessary to cause functional changes.
