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.

* being offered treatment with DTM SCS
* being at least 18 years old

Exclusion Criteria:
