- Patient willing to comply with study protocol including attending the study visits
Exclusion Criteria:
- Expected inability of patients to receive or properly operate the spinal cord stimulation system
- History of coagulation disorders, lupus erythematosus, diabetic neuropathy, rheumatoid arthritis or morbus Bechterew
- Active malignancy
- Addiction to any of the following drugs, alcohol (5E/day) and/or medication
- Evidence of an active disruptive psychiatric disorder or other known condition significant enough to impact perception of pain, compliance to intervention and/or ability to evaluate treatment outcome as determined by investigator
- Immune deficiency (HIV positive, immunosuppressiva, etc.)
- Life expectancy < 1 year
- Local infection or other skin disorder at site of incision
- Pregnancy
- Other implanted active medical device
