入选标准

  • 1. A spinal cord injury (complete or incomplete lesion) of at least 2 years
  • 2. Injury at T12/L1 or above
  • 3. A disability grade on the American Spinal Injury Association (ASIA) Impairment Scale (AIS) of A, B, C or D as determined by a qualified examiner
  • 4. Neuropathic pain as determined clinically by the investigator at or below the level of the SCI
  • 5. Average pain intensity for the target pain area of > = 5 out of 10 cm on the Visual Analogue Scale (VAS) at enrollment when the patient is taking medication
  • 6. Stable chronic pain for at least 4 weeks
  • 7. Refractoriness to pain treatment as determined by the Investigator (which can include medication and/or other treatment modalities)
  • 8. On stable pain medications, as determined by the Investigator, for at least 4 weeks prior to the Baseline Visit
  • 9. An appropriate candidate for EVOKE™ Spinal Cord Stimulation implant as determined by the Investigator
  • 10. An appropriate candidate for the surgical procedures required in this study based on the clinical judgment of the implanting physician and if applicable per the local regulations
  • 11. An adult (> = 18 years of age) at the time of enrolment
  • 12. Willing and capable of giving written informed consent prior to any investigational related procedure (if not able to write consent will happen through legal or personal representative)
  • 13. Willing and able to comply with study-related requirements, assessments and visits
  • These decisions are based on the clinical judgement of the investigator.

排除标准

  • 1. Evidence of an active disruptive psychological or psychiatric disorder or other known condition significant enough to impact perception of pain, compliance of intervention and/or ability to evaluate treatment outcome, as determined by the investigator in consultation with a clinical psychologist
  • 2. A current diagnosis of a progressive neurological disease such as multiple sclerosis, inflammatory, infective, vascular, demyelinating polyneuropathy, rapidly progressive arachnoiditis, rapidly progressive diabetic peripheral neuropathy, brain or spinal cord tumor, or severe/critical spinal stenosis
  • 3. An invalid AIS (e.g. ASIA motor exam not obtainable)
  • 4. A current diagnosis or condition such as a coagulation disorder, bleeding diathesis, platelet dysfunction, progressive peripheral vascular disease or uncontrolled diabetes mellitus that presents excess risk for performing the procedure as determined clinically by the investigator.
  • 5. A diagnosis that precludes lead placement (e.g. severe scoliosis, presence of metalwork)
  • 6. Radiographic evidence of spinal instability requiring fusion as determined by the Investigator
  • 7. Previous and/or current experience with drug pump and/or neurostimulator or another active implantable device such as a pacemaker
  • 8. Metastatic malignant disease or active local malignant disease
  • 9. A life expectancy of less than 1 year
  • 10. An active systemic or local infection
  • 11. Pregnant (if female and sexually active, subject must be using a reliable form of birth control, be surgically sterile or be at least 2 years post-menopausal)
  • 12. Within 6 months of enrollment a significant untreated addiction to dependency producing medications or have been a substance abuser (including alcohol and illicit drugs)
  • 13. Benefitting within 30 days prior to enrollment from an interventional procedure and/or surgery to treat the targeted pain area
  • 14. Concomitantly participating in another clinical study, or planned to be enrolled in another clinical study
  • Decisions will be based on the clinical judgement of the investigator.
