1. A system for reducing a perception of pain in a human comprising:
a coiled lead;
an electrode located on a distal end of the coiled lead, wherein at least a portion of the coiled lead and the electrode are configured to be inserted in-vivo at a position to electrically stimulate at least one target afferent sensory nerve fiber of a nerve, wherein the electrode is spaced from the nerve;
an electrical pulse generator operatively coupled with the coiled lead, the electrical pulse generator is configured to apply electrical stimulation in a random or pseudo-random manner, wherein the electrical stimulation generates a stochastic response of action potentials in the at least one target afferent sensory nerve fiber while avoiding generation of action potentials in small sensory nerve fibers due to the electrode being spaced from the nerve and wherein the electrical stimulation comprises a frequency of 4 kHz to 20 KHz.
