Outcome Measures

Primary Outcomes (1)

  • Functional connectivity

    EEG recordings to measure functional connectivity in the brain

    The change between baseline and 1 month after definitive implantation of the neurostimulator

Secondary Outcomes (5)

  • Functioning of the descending inhibitory pathway

    The change between baseline and 1 month after definitive implantation of the neurostimulator

  • Visual Analogue Scale (VAS) pain diary

    Three times every day (morning, afternoon and evening), starting 1 month before baseline measurements up to the second measurement 1 month after definitive implantation of the neurostimulator (at study completion).

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

    The difference between 1 month before baseline measurements and 1 month before the second measurement (1 month after definitive implantation).

  • Pain Catastrophizing

    The change between baseline and 1 month after definitive implantation of the neurostimulator

  • Subjective sleep quality

    The change between baseline and 1 month after definitive implantation of the neurostimulator

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (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
  • Subjects 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
