This study looks at lead migration during a Spinal Cord Stimulation (SCS) trial. SCS is a procedure that uses electrical leads to reduce pain in chronic back pain patients. Researchers want to know if the distance that leads move (or "migrate") affects how well pain relief works. They will compare two groups: one with leads held by an anchor and another with leads held by both an anchor and a suture (a type of stitch).

Participants will have their SCS trial as usual, then answer an activity survey and have an image taken to check the lead positions. The study will also check if temperature or humidity affects lead movement.

• Participants must be adults with chronic back pain, seen by specific anesthesiologists.
• The study excludes those allergic to local anesthetics or with skin infections.
• No compensation is mentioned; the focus is on understanding pain relief outcomes.

If interested, ensure you meet the criteria and are comfortable with the procedures and surveys involved. This study could help improve SCS procedures and pain relief in the future.
