Outcome Measures

Primary Outcomes (1)

  • Exhaled breath changes

    The investigators will examine the difference in exhaled breath patterns between both measurements (SCS on versus SCS off), measured with the Aeonose.

    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.

Secondary Outcomes (1)

  • 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.

Study Arms (2)
