Inclusion criteria

* Subject is at least 18 years old. * Diagnosis of FBSS (Failed conservative treatments for pain including but not limited to pharmacological therapy and physical therapy) and currently being treated with spinal cord stimulation. * Cognitive and language functioning enabling coherent communication between the examiner and the participant.

Exclusion criteria

* Patients with impaired skin integrity at the fingers. * Patients with major psychiatric problems.

Design outcomes

Primary

Measure	Time frame	Description
Skin conductance changes	Two times on the same day; once while SCS is switched off and once while SCS is switched on. Total study duration lasts one day.]	The investigators will examine the difference in skin conductance between both measurements (SCS on versus SCS off)
Respiration rate	Two times on the same day; once while SCS is switched off and once while SCS is switched on. Total study duration lasts one day.]	The investigators will examine the difference in respiration rate between both measurements (SCS on versus SCS off)

Secondary

Measure	Time frame	Description
Pain intensity scores using the Visual Analogue Scale	Two times on the same day; once while SCS is switched off and once while SCS is switched on. Total study duration lasts one day.]	Pain intensity score on that time on a Visual Analogue Scale (VAS) ranging from zero (no pain) towards 10 (worst possible pain) for the pain intensity.
