* Successful two-week SCS testing period with tonic stimulation (≥2 points reduction in leg pain NRS from baseline). This means patients will experience paresthesia during the SCS trial period
* Mandatory assessment at the Multidisciplinary outpatient clinic for back-, neck- and shoulder rehabilitation, St. Olavs University Hospital

Exclusion Criteria:
