Is this trial a fit for you?
✓Likely a good fit
Adults with chronic PSPS-T2 pain (≥6 months) and moderate or greater baseline pain who are offered DTM SCS and can operate the device.
✕Probably not a fit
Patients with contraindications to SCS, inability to operate the device, or factors that significantly affect pain perception or adherence may not benefit.

What this trial studies
This observational study evaluates the effectiveness and safety of differential target multiplexed spinal cord stimulation (DTM SCS) in adults with PSPS-T2. It aims to identify parameters like frequency, pulse duration, amplitude, and recharge needs, and to monitor safety and battery use. Participants are adults with chronic PSPS-T2 pain who are offered DTM SCS and meet specific inclusion/exclusion criteria. Data collected include pain relief, device performance, and potential adverse events in a real-world setting.
Why it matters
Potential benefit: If successful, participants may experience better pain control and quality of life with optimized SCS settings.
How similar studies have gone: Previous research in spinal cord stimulation for chronic back and leg pain supports benefit in selected patients, though the specific DTM approach is relatively novel.

Inclusion Criteria: * having chronic pain as a result of PSPS-T2 that exists for at least 6 months with at least moderate pain intensity (4 or higher measured on numeric rating scale (NRS) or 31mm or higher measured on visual analogue scale (VAS) for the dominant pain location. * being offered treatment with DTM SCS * being at least 18 years old Exclusion Criteria: * Expected inability of patients to properly operate the SCS system * History of coagulation disorders, lupus erythematosus, diabetic neuropathy * Active malignancy * Addiction to drugs and/or alcohol (more than 5 units /day) * Evidence of an active disruptive psychiatric disorder or other known condition significant enough to impact perception of pain, compliance to intervention and/or ability to complete questionnaires, as determined by the investigator * Immune deficiency (e.g. HIV positive, immunosuppressiva) * Life expectancy \< 1 year * Local infection or other skin disorder at site of incision * Pregnancy * Other implanted active medical device
