Outcome Measures
Primary Outcomes (1)
Number of participants with change in stimulation sensation
Stimulation sensation will be characterized by study participants as better, worse or same for 5 different closed-loop sensitivity settings.
6-months
Secondary Outcomes (3)
NRS
Baseline, 3-months, 6-months, 12-months post-implant
Number of participants with reduced pain distribution
Baseline, 3-months, 6-months and 12-months post-implant
Paraesthesia mapping
3-months, 6-months and 12-months post-implant
Interventions
Spinal cord stimulation that measures and records evoked compound action potentials (ECAPs) and automatically adjusts the stimulation current to maintain a consistent ECAP amplitude
Eligibility Criteria
Subjects suffering from chronic pain and are eligible for SCS trial and permanent implant.
You may qualify if:
- Subject is deemed a suitable candidate for SCS trial and permanent implant and has been routinely scheduled to undergo an SCS trial phase with the Evoke SCS System.
- Subject has a minimum of pain intensity of 5/10 on the numeric rating scale (NRS) at baseline
- Subject is ≥ 18 years old.
- Subject is not pregnant or nursing.
- Subject is willing and capable of giving informed consent.
You may not qualify if:
- Subject currently has an active implantable device including pacemakers, spinal cord stimulator or intrathecal drug delivery system.
- Subject is incapable of understanding or responding to the study questionnaires.
- Subject is incapable of understanding or operating the patient programmer handset.
