Brief Summary

This study is an interventional prospective observatory single center trial, investigating the supraspinal effects of long term conventional SCS (60 Hz) and paresthesia-free high density SCS in failed back surgery syndrome (FBSS) patients with back and leg pain completed with resting state functional magnetic resonance (rs fMRI) and voxel-based magnetic resonance morphometry (VBM).

Conditions

Failed Back Surgery Syndrome

Keywords

spinal cord stimulation; resting state functional magnetic resonance; voxel-based magnetic resonance morphometry

Outcome Measures

Primary Outcomes (2)

• Grey Mater Volume assessed by Voxel-based morphometry analysis (based on MRI images)

  The change between baseline and 1 month after definitive implantation (T1) and the change between baseline and 2 months after definitive implantation (T2).

• Functional connectivity analysis using in-house developed software (based on MRI images)

  The change between baseline and 1 month after definitive implantation (T1) and the change between baseline and 2 months after definitive implantation (T2).

Secondary Outcomes (5)

• Visual Analogue Scale (VAS) pain diary

  Three times every day (morning, afternoon and evening), starting 1 week before baseline measurements up to 2 months until study completion.

• Objective sleep quality will be measured using the Actiwatch spectrum plus (Respironics).

  The difference between 7 days at baseline before implantation and 7 days before T1 ( 1 month after definitive implantation) and 7 days before T2 ( 2 months after definitive implantation).

• Subjective sleep quality will be measured by the Pittsburgh Sleep Quality Index (PSQI)

  The change between baseline and 1 month after definitive implantation (T1) and the change between baseline and 2 months after definitive implantation (T2).

• Pain catastrophizing is assessed by the Pain Catastrophizing Scale (PCS)

  The change between baseline and 1 month after definitive implantation (T1) and the change between baseline and 2 months after definitive implantation (T2).

• Likert-scale in order to evaluate the satisfaction grade of the patient.

  The change between baseline and 1 month after definitive implantation (T1) and the change between baseline and 2 months after definitive implantation (T2).

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject is at least 18 years old.
• Subject is able and willing to comply with the follow-up schedule and protocol
• Diagnosis of FBSS with predominant leg pain (VAS) \> 5) and non-dominant back pain.
• Cognitive and language functioning enabling coherent communication between the examiner and the subject;
• Failed conservative treatments for pain including but not limited to pharmacological therapy and physical therapy
• Stable neurologic function in the past 30 days
• In the opinion of the Investigator, the subject is psychologically appropriate for the implantation for an active implantable medical device
• Subject is able to provide written informed consent
• Subject speaks Dutch or French.

You may not qualify if:

• Female subject of childbearing potential is pregnant/nursing, or plans to become pregnant during the course of the trial
• Subject has had radiofrequency treatment of an intended target DRG within the past 3 months
• Subject currently has an active implantable device including ICD, pacemaker, spinal cord stimulator, deep brain stimulator or intrathecal drug pump
• Subject is unable to operate the device or has no relative available.
• Subjects with indwelling devices that may pose an increased risk of infection
• Subject currently has an active infection
• Subject has, in the opinion of the Investigator, a medical comorbidity that contraindicates placement of an active medical device
• Subject has participated in another clinical investigation within 30 days
• Subject has a coagulation disorder or uses anticoagulants that, in the opinion of the investigator, precludes participation
• Subject has been diagnosed with cancer in the past 2 years
• Life expectancy \< 6 months
• Imaging (MRI, CT, x-ray) findings within the last 12 months that, in the Investigator's opinion, contraindicates lead placement
• Existing extreme fear for entering MRI
• General contraindication for MRI (pacemaker, etc…)
• Age male/female patient \<18 years
