Skin conductance changes
The investigators will examine the difference in skin conductance between both measurements (SCS on versus SCS off)
Time frame: 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.]
Respiration rate
The investigators will examine the difference in respiration rate between both measurements (SCS on versus SCS off)
Time frame: 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 scores using the Visual Analogue Scale
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.
Time frame: 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.]
