About this trial

This is an interventional treatment trial for Chronic Pain focused on measuring Spinal Cord Stimulation, Chronic Pain

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Key Inclusion Criteria:

  • Average unilateral foot, or knee or groin pain intensity of 6 or greater on a 0-10 numerical rating scale at Baseline Visit based on 7-day average NRS score
  • Subject signed a valid, EC-approved informed consent form (ICF)
  • Willing and able to comply with all protocol-required procedures and assessments/evaluations
  • 18 years of age or older when written informed consent is obtained

Key Exclusion Criteria:

  • Significant cognitive impairment at Screening that, in the opinion of the Investigator, would reasonably be expected to impair the study candidates to participate in the study
  • Participating (or intends to participate) in another drug or device clinical trial that may influence the data that will be collected for this study
