Industry-leading Clinical Evidence in SCS

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.
