Conditions

Outcome Measures

Primary Outcomes (1)

  • Percent Change in Visual Analogue Scale (VAS) Pain

    Visual Analogue Scale (VAS) to rate pain intensity (0mm \[no pain\] to 100mm \[worst pain imaginable\])

    3-months post-implant

Secondary Outcomes (2)

  • Incidence of device- and procedure-related adverse events

    through 60-months post-implant

  • Measurement of ECAPs by the Evoke SCS System

    through 60-months post-implant

Study Arms (1)

ECAP-controlled, closed-loop SCS

Spinal cord stimulation that measures and records evoked compound action potentials (ECAPs) and automatically adjusts the stimulation current to maintain a consistent ECAP amplitude

Device: Evoke Spinal Cord Stimulation (SCS) System

Interventions

A spinal cord stimulation system that measures and records evoked compound action potentials (ECAPs) and automatically adjusts the stimulation current to maintain a consistent ECAP amplitude

ECAP-controlled, closed-loop SCS
