Outcomes
Primary Outcome Measures
Sweat gland function by measuring Electrochemical Skin Conductances (ESC)
The investigators will examine the difference in sweat gland function between both measurements (SCS on versus SCS off), measured with the Sudoscan.
Secondary Outcome Measures
Pain intensity scores using the Visual Analogue Scale
Pain intensity score on that time on a Visual Analogue Scale (VAS) from zero (no pain) towards 10 cm (worst possible pain) for the pain intensity.

Primary Outcome Measure Information:
Title
Sweat gland function by measuring Electrochemical Skin Conductances (ESC)
Description
The investigators will examine the difference in sweat gland function between both measurements (SCS on versus SCS off), measured with the Sudoscan.
Time Frame
The change between the measurement while SCS is switched off and while SCS is switched on. Total study duration lasts one day.
Secondary Outcome Measure Information:
Title
Pain intensity scores using the Visual Analogue Scale
Description
Pain intensity score on that time on a Visual Analogue Scale (VAS) from zero (no pain) towards 10 cm (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.
