Outcome Measures

Primary Outcomes (1)

  • Heart rate variability changes

    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 Outcomes (1)

  • Pain intensity scores

    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)

SCS off

EXPERIMENTAL
Other: SCS is switched off

SCS on

EXPERIMENTAL
Other: SCS is switched on

Interventions

Spinal cord stimulator is switched off for 12 hours

SCS off

Spinal cord stimulator is on

SCS on

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • 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.

You may not qualify if:

  • 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).
