1. A method of reducing a perception of pain by a human body, the method comprising the steps of:
- placing an electrode at a therapeutically effective distance spaced from a neural fiber bundle within said body, wherein said neural fiber bundle comprises at least one of a Type Ia and Ib afferent nerve fiber with at least one of Type III and Type IV nerve fibers; and
delivering electrical stimulation from said electrode to said neural fiber bundle to reduce a perception of pain by said human, wherein saidat least one Type Ia and Ib afferent nerve fiber of said neural fiber bundle are selectively activated whileminimizing recruitment of activation of said at least one of Type III and Type IV nerve fiber of said neural fiber bundle due to the electrode being at the therapeutically effective distance.

Abstract
Systems and methods are provided for applying electrical stimulation to a body by an electrode spaced from a target nerve of passage. It has been discovered that pain felt, or perceived to be felt, in a given region of the body can be treated by stimulating muscle close to a “nerve of passage” in a region that is superior (i.e., cranial or upstream toward the spinal column) to the region where pain is felt, such as in a case of post-amputation residual limb pain, or purportedly felt in the case of post-amputation phantom limb pain.

19. A method of reducing a perception of pain by a human body, the method comprising the steps of:
-
placing an electrode at a therapeutically effective distance spaced from a neural fiber bundle within the body, wherein said neural fiber bundle comprises at least one of a Type Ia and Ib afferent nerve fiber plus an efferent nerve fiber; and delivering electrical stimulation from said electrode to said neural fiber bundle to reduce a perception of pain by said human, wherein said at least one of Type Ia and Ib afferent nerve fiber of said neural fiber bundle are selectively activated while minimizing recruitment of activation of said efferent nerve fiber of said neural fiber bundle due to the electrode being at the therapeutically effective distance. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)

27. A method of reducing a perception of pain by a human body, the method comprising the steps of:
-
placing an electrode at a therapeutically effective distance spaced from a neural fiber bundle within said body, wherein said neural fiber bundle comprises more than one type of nerve fiber, wherein said therapeutically effective distance is about 0.2 centimeters to about 3.0 centimeters from said neural fiber bundle; and delivering electrical stimulation from said electrode to said neural fiber bundle to reduce a perception of pain by said human, wherein a first of said type of nerve fiber is selectively activated while minimizing recruitment of activation of a second of said type of nerve fiber due to the electrode being at the therapeutically effective distance, wherein said second of said type of nerve fiber includes at least one of a Type III, Type IV and efferent nerve fiber. - View Dependent Claims (28, 29, 30, 31, 32)
