Detaljerad beskrivning

DISCOVER will measure the effectiveness of high-density spinal cord stimulation for treatment of chronic back and leg pain. Identification of clinical effective parameters concerning location of active electrodes, frequency, pulse duration, amplitude and battery consumption are, besides safety, the major outcome parameters of this study.

Studera befolkning

Patients with chronic back and leg pain (due to Failed Back Surgery Syndrome) who either received SCS or have not sufficient pain reduction with traditional parameters or patients with chronic back and leg pain who are candidate for SCS will receive HD SCS.

Beskrivning

Inclusion Criteria:

  • Failed Back Surgery Syndrome patients (FBSS) with insufficient pain reduction with conventional SCS or FBSS patients suitable for SCS
  • Age > 18 years
  • Chronic pain as a result of FBSS that exists for at least 6 months with a pain intensity 5 or higher measured on numeric rating scale (NRS)
  • Patient has been informed of the study procedures and has given written informed consent
  • Patient willing to comply with study protocol including attending the study visits

Exclusion Criteria:

  • 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
  • Addiction to any of the following drugs, alcohol (5E/day) and/or medication
  • 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
  • Immune deficiency (HIV positive, immunosuppressiva, etc.)
  • Life expectancy < 1 year
  • Local infection or other skin disorder at site of incision
  • Pregnancy
  • Other implanted active medical device
