Layout table for eligibility information
Ages Eligible for Study:   22 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Key Inclusion Criteria:

  • Chronic low back pain, with or without leg pain, for at least 6 months
  • Received at least 90 days of documented pain management care to address the primary pain complaint, prior to Screening (e.g. medication, physical therapy)
  • If female of childbearing potential: not pregnant, as evidenced by a negative pregnancy test at Screening
  • Subject signed a valid, IRB-approved informed consent form (ICF) provided in English

Key Exclusion Criteria:

  • Primary pain complaint of vascular origin (e.g. peripheral vascular disease)
  • Require implantation of lead(s) in the cervical epidural space
  • Significant cognitive impairment at Screening that, in the opinion of the Investigator, would reasonably be expected to impair the study candidate's ability to assess pain intensity
  • Previous failed spinal cord stimulation trial or is already implanted with an active implantable device(s) (e.g. pacemaker, drug pump, implantable pulse generator)
