Study Summary

This study evaluates the effects of peripheral nerve stimulation on opioid craving and use and pain in participants with chronic non-cancer pain (NCP) and opioid misuse. Participants will be randomized to receive the active or sham control treatment for the duration of the study.

Each participant will be given the Empower app and trained on app use. They will record pain levels daily on the Empower app, with a 0-100 scale. 0 indicating a lack of pain outcome, and 100 indicating maximum pain score. Pain score measures will be taken throughout the study. The Empower App will prompt all participants daily to complete the Numeric Rating Scale to assess pain levels immediately before and after treatment. Participants complete daily measures of Visual Analog Scale for scores
