Inclusion Criteria:

  • Patients with FBSS defined as persistent or recurrent back and/or leg pain despite one or more anatomically successful back surgeries for the same original pain.
  • Age 18-75 years old at consent.
  • Targeted pain intensity of ≥ 5 out of 10 on the Baseline visit NRS.
  • ODI score of 41-80 out of 100 at the Baseline visit.
  • Appropriate candidate for the surgical procedure and Algovita SCS therapy based on the clinical judgment of the investigator and the Algovita Instructions for Provider (IFP) in the Nuvectra product manuals.
  • On stable pain medications for at least 28 days prior to consent. Stable is defined as no new or discontinued pain medications and no changes to total daily dose of any pain medications.

Exclusion Criteria:

  • Has a medical/psychological/psychiatric condition/disorder that could interfere with study procedures as determined by the investigator.
  • Has a coexisting pain condition that might confound pain ratings, as determined by the investigator.
  • Has a condition currently requiring or likely to require the use of MRI or diathermy.
  • Has an existing drug pump, SCS System, or other active implantable device.
  • Has any prior SCS experience.
  • Pregnant or planning to become (if female and sexually active, subject must be using a reliable form of birth control, be surgically sterile, or be at least 2 years postmenopausal).
  • For subjects with diabetes, HbA1c ≥ 8.5% as measured at the Baseline visit (or within the 3 months prior to the Baseline visit).

Ramy czasowe
Effectiveness of targeted pain reduction compared to baseline in each treatment arm
Ramy czasowe: Week 25

The percentage of participants who experience at least a 50 percent reduction in targeted pain from baseline, as assessed by Numeric Rating Scale (NRS). The Numeric Rating Scale (NRS) will range from 0 to 10 with a higher score indicating a higher level of pain.

Effectiveness will be compared both descriptively and statistically between the two randomized treatment groups using crossover analysis methods.

Week 25
Rate of serious study-related adverse events (AEs) in each treatment arm
Ramy czasowe: From Permanent Implant through Week 25
The rate of serious study-related AEs. Study-related AEs are defined as any device, procedure and therapy/stimulation-related AEs.
