Description

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:

  • The presence of one or more coexisting conditions known to affect HRV analysis (including but not limited to atrial fibrillation, numerous atrial or ventricular extra beats, paced rhythm, left ventricular bundle branch block, cancer, kidney or hepatic failure, and diabetes mellitus (autonomic nervous system dysfunction)).
  • The use of medication that directly modifies autonomic control (for example beta-blockers).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Heart rate variability changes
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.
The investigators will examine the difference in heart rate variability between both measurements (SCS on versus SCS off)
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain intensity scores
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 on a visual analogue scale ranging from zero (no pain) towards 10 (worst possible pain).
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.
