  Purpose

The purpose of this study is to determine if electrical stimulation (small levels of electricity) can safely and effectively reduce post-amputation pain. This study involves a device called the Smartpatch System. The Smartpatch System delivers mild electrical stimulation to nerves in the residual limb. The Smartpatch System includes a small wire (called a "lead") that is placed through the skin in the upper leg. It also includes a device worn on the body that delivers stimulation (called the Smartpatch Stimulator).

Arms Assigned Interventions
Experimental: Smartpatch Group 1
Subjects in Group 1 will have a Smartpatch Lead placed in the residual limb in location 1 in the upper leg. These subjects will then use the Smartpatch Peripheral Nerve Stimulation (PNS) System and will receive electrical stimulation.
