EVA: Evaluation of EVOKE Therapy Metrics Generated Using the Evoke System With EVA

The Evoke Spinal Cord Stimulator (SCS) System (Evoke® System) is an FDA-approved device that is used to manage long lasting, severe pain that is not relieved by typical medical treatments. This research registry is being conducted to collect data from patients treated with a SCS device in order to determine how the device impacts their chronic pain condition. Specifically, the study aims to: * Evaluate data collected from the SCS system on how well the system is working. * Evaluate the feasibility of programming the SCS system independently without external assistance. * Evaluate changes in physical function, fatigue, pain interference, mood, sleep, daily activities, pain control, and overall satisfaction with the device.
