Field Shape and Amplitude Sensitivity Exploratory Study (CONTOUR Study)
Chronic Neuropathic Pain in the Low Back and Legs
About this trial
This is an interventional other trial for Chronic Neuropathic Pain in the Low Back and Legs focused on measuring chronic neuropathic pain in the low back and legs, subperception spinal cord stimulation
Eligibility Criteria
Key Inclusion Criteria:
- Documented average low back pain intensity of at least 6 out of 10 and greater or equal than average leg pain intensity over 7 days during screening (Numerical Rating Scale)
- Stable daily pain-related medication prescription and intake of ≤100mg morphine-equivalents
- Capacity to describe and rate pain intensity, complete study measurements, and use the study device (e.g. patient remote control, charger, diary ratings) (physician discretion)
Key Exclusion Criteria:
- Presence of pain or psychological condition that in the opinion of the investigator may interfere with the subject's ability to rate their pain and communicate such ratings
- Previous Spinal Cord Stimulation trial or is already implanted with an active implantable device(s) (e.g. pacemaker, drug pump, implantable pulse generator)
Sites / Locations
- St. Bartholomew's Hospital
- James Cook University Hospital
