Clinical Trial Comparing Ultra-High Versus Traditional Pulse Widths Using the ALGOVITA® SCS System High Fidelity Stimulation in the Treatment of Persistent or Recurrent Back and/or Leg Pain Following Spinal Surgery

The objective of this study is to obtain post-market clinical outcome data for the Algovita SCS System when used on-label, according to the applicable directions for use, using high fidelity tonic stimulation at either ultra-high pulse width or traditional pulse width for the treatment of persistent or recurrent back and/or leg pain following spinal surgery.

  • 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).

¿Qué mide el estudio?

Medidas de resultado primarias

Medida de resultado
Medida Descripción
Periodo de tiempo
Effectiveness of targeted pain reduction compared to baseline in each treatment arm
Periodo de tiempo: 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
Periodo de tiempo: 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.
From Permanent Implant through Week 25

Periodo de tiempo: Week 12 and Months 12, 18 and 24
The percentage of participants who experience at least a 50 percent reduction in targeted pain 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.
Week 12 and Months 12, 18 and 24
Effectiveness of back and/or leg pain reduction compared to baseline in each treatment arm
Periodo de tiempo: Weeks 12 and 25, and Months 12, 18 and 24
