This study is about using a special device, called the Evoke System, to help treat chronic pain, which is pain that lasts a long time, in the trunk (middle part of the body) or limbs (arms and legs). The device uses something called ECAP-controlled closed-loop SCS. This is a way to send signals to nerves to help control pain. The study checks how well this method works. People who can join the study are those already planning to use the Evoke System for pain management. They need to have a high level of pain, scoring 6 or more on a pain scale from 0 to 10, and must be able to speak and understand English. They need to be adults and not pregnant.

• The study involves a temporary trial with the Evoke System.
• Participants must be able to follow the study procedures and attend visits.
• There are no specific exclusion criteria mentioned, meaning most people who meet the inclusion criteria can join.
