NCT01181817

Brief Summary

Functional Magnetic Resonance Imaging (fMRI)and MR Spectroscopy of the brain are perfect tools to investigate the changes in the brainstem and brain evoked by the orthodromically impulses of a SCS.

Outcome Measures

Primary Outcomes (1)

  • functional and neurobiological cerebral changes due to SCS

    To compare brain activity before and after spinal cord stimulation (with appropriate paraesthesia) using functional magnetic resonance imaging and neurobiological changes in the spectrum (gamma-aminobutyric acid (GABA) glutamate (Glu) glutamine (Gln) N-acetylaspartate (NAA) Choline-containing compounds (Cho) Creatine plus phophocreatine (total creatine: Cr) Myo-inositiol (Ins) Choline (Cho) Glucose (Glc) Lactate (Lac)) due to stimulation measured by MRS. The primary outcome is the difference in neurobiology between baseline and when the stimulator is on.

Eligibility Criteria

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

You may qualify if:

  • Age male/female patient ≥ 18 years
  • Patient diagnosed with Failed Back Surgery Syndrome with at least one prior spinal surgery
  • Patient with low back pain and/or pain in at least one leg
  • Pain intensity at baseline assessed by VAS \> 5 (50%)
  • Patient willing to provide informed consent.

You may not qualify if:

  • Use of spinal cord stimulation in this patient in the past.
  • Presence of other clinically significant or disabling chronic pain condition
  • Expected inability of patients to receive or properly operate the spinal cord stimulation system
  • History of coagulation disorders, lupus erythematosus, diabetic neuropathy, rheumatoid arthritis or morbus Bechterew
  • Active malignancy
  • Current use of medication affecting coagulation which cannot be temporarily stopped
  • Evidence of an active disruptive psychiatric disorder or other known condition significant enough to impact perception of pain, compliance to intervention and/or ability to evaluate treatment outcome as determined by investigator
  • Life expectancy of less than 1 year
  • Existing or planned pregnancy
  • Existing extreme fear for entering MRI
