The Most Robust Body of Clinical Evidence

No other company has committed so fully to establishing clinical evidence for the safety and efficacy of a spinal cord stimulation (SCS) system with large-scale randomized clinical trials (RCTs) targeting indication expansion.

Durable Relief for Back and Leg Pain

The landmark SENZA-RCT2 demonstrated long-term safety and improved efficacy for both back and leg pain with 10 kHz Therapy.

Real-World Outcomes

In a real-world study3, chronic back pain patients
achieved a 74% responder rate, mirroring
the excellent outcomes of the SENZA-RCT.


Demonstrated Pain Relief for PDN

The SENZA-PDN, a large multi-center RCT, shows meaningful long-term pain relief with 10 kHz Therapy4.
