Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if pain can be relieved by delivering small amounts of electricity (called "electrical stimulation") to the nerves in an individual's amputated leg.This study will involve the use of a Peripheral Nerve Stimulation (PNS) System that is made by SPR Therapeutics (the sponsor of the study). The PNS System was cleared by the FDA for up to 60 days of use for the management of chronic pain, including extremity (leg) pain.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1 (Treatment)

Subjects in Group 1 will have Leads placed in the residual limb in the upper leg. These subjects will then use the SPRINT Peripheral Nerve Stimulation (PNS) System and will receive electrical stimulation for 8 weeks.

Group Type ACTIVE_COMPARATOR

SPRINT Peripheral Nerve Stimulation (PNS) System

Intervention Type DEVICE

The SPRINT System delivers mild electrical stimulation to nerves in the residual limb. The SPRINT System includes two small wires (called "Leads") that are placed through the skin in the upper leg. It also includes a device worn on the body that delivers stimulation (called the SPRINT Stimulator).

Group 2 (Control)

Subjects in Group 2 will have Leads placed in the residual limb in the upper leg. These subjects will then use the SPRINT Peripheral Nerve Stimulation (PNS) System and receive 8 weeks of sham stimulation. Subjects will then have the option to crossover and receive stimulation therapy.

Group Type SHAM_COMPARATOR
