Patient Experience Comparing Tonic Vs. Burst Spinal Cord Stimulation For Chronic Pain

Not Applicable

Terminated

• Conditions: Chronic Pain
• Interventions: Device: Spinal Cord Stimulator

• Registration Number: NCT04159753
• Lead Sponsor: Mayo Clinic

Brief Summary

Researchers are evaluating if subjects who have already experienced tonic spinal cord stimulation would have a better pain relief status with burst spinal cord stimulation.

Detailed Description

The study is a controlled trial with subjects that have an already-implanted SCS device (Eon Mini™) and are not satisfied with their pain relief status. As part of medical standard of care, patients with already-implanted Eon family tonic implantable pulse generators (IPGs) have the opportunity to experience burst stimulation for 30-Day Trial FDA approved. The aim of the study record patients experience during the 30-Day Trial using standard questionnaires.

Primary Outcome Measures

Name	Time	Method
Pain intensity	Participants will be followed at baseline, before and after the 2-3 weeks burst reprograming trial, and 3-8 months after burst trial ends	Change in Pain scores using Numeric Rating Scale (1-10)
Pain quality, intensity and localization	Participants will be followed at baseline, before and after the 2-3 weeks burst reprograming trial, and 3-8 months after burst trial ends	Change in pain perception using Short-Form McGill Pain Questionnaire-2
Pain perception	Participants will be followed at baseline, before and after the 2-3 weeks burst reprograming trial, and 3-8 months after burst trial ends	Change in pain perception using the Pain Catastrophizing Scale self-reported survey

Secondary Outcome Measures

Name	Time	Method
