Study Summary

This trial is testing a new way to provide deep brain stimulation (DBS) for people with chronic pain that has not been relieved by other treatments. DBS involves surgically placing a small device in the brain that sends electrical signals to specific areas. The goal of this trial is to find out whether DBS is more effective when it is turned on only when needed, rather than continuously.
