Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Composite Endpoint Success

    The primary endpoint is a composite endpoint. A success is defined as a reduction in overall trunk and limb VAS pain score greater than or equal to 50 percent and no increase in baseline pain medication. VAS = Visual Analog Scale, from 0 to 100 mm, where 0 = no pain and 100 = worst imaginable pain.

    3 months

Secondary Outcomes (9)

  • Percent Change From Baseline in Leg Pain VAS Score

    3 months

  • Percent Change From Baseline in Back Pain VAS Score

    3 months

  • Proportion of Subjects With Greater Than or Equal to 80% Reduction From Baseline in Overall Trunk and Limb Pain VAS Score

    3 months

  • Proportion of Subjects With Greater Than or Equal to 50% Reduction From Baseline in Back Pain VAS Score

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subject is male or female between the ages of 18 and 80 years.
  • Have been diagnosed with chronic, intractable pain of the trunk and/or limbs, which has been refractory to conservative therapy for a minimum of 6 months.
  • Be an appropriate candidate for an SCS trial and the surgical procedures required in this study based on the clinical judgment of the Investigator.
  • Be willing and capable of giving informed consent and able to comply with study-related requirements, procedures, and visits.

You may not qualify if:

  • Have a medical condition or pain in other area(s), not intended to be treated with SCS, that could interfere with study procedures, accurate pain reporting, and/or confound evaluation of study endpoints, as determined by the Investigator.
  • Have 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 outcomes.
  • Have an existing drug pump and/or SCS system or another active implantable device such as a pacemaker, deep brain stimulator (DBS), or sacral nerve stimulator (SNS).
  • Have prior experience with SCS.
  • Have an active systemic infection or local infection in the area of the surgical site.
  • Be pregnant or nursing (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).
  • Be concomitantly participating in another clinical study.
