| 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. | The change between the measurement while SCS is switched off and while SCS is switched on. Total study duration lasts one day. |
| Measure | Description | Time Frame |
|---|---|---|
| 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. | 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. |
