Mechanisms of Stimulation for Pain Alleviation

This trial studies 2 FDA approved peripheral nerve stimulation devices that may reduce pain by sending electrical pulses to the nerve. The SPR SPRINT PNS System, a matchbox-sized, battery-powered wearable stimulator that uses a Mircrolead to deliver stimulation for pain relief. There is a small wireless hand-held remote that is used to activate/ adjust intensity of stimulation. Stimulation delivered by this device may interrupt pain signals and increase non-pain signals. The SPR SPRINT device is used for 60 days before the percutaneous Microlead(s) are removed. The Nalu PNS System, a dime-sized micro-implantable pulse generator (IPG) leveraging advanced microelectronics. The micro-IPG is powered by an externally worn therapy disc via radiofrequency worn over the IPG site with an adhesive clip applied to the skin or a relief belt. The device is remote-controlled by patients via an app.

CMM-Only participants will receive conventional medical management for the duration of their time in the study.
