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)
