The indication covers chronic low back and leg pain in people without prior back surgery — called non-surgical back pain (NSBP).

Boston Scientific says first-line treatment for people with chronic back pain tends to have limitations. Conventional medical management like physical therapy and medication tend to prove less effective for many people. Effective chronic pain management may lead to improved quality of life and reduced opioid use.

In a news release, Dr. James North of the Carolinas Pain Institute said this expanded indication helps people with limited treatment options. North also served as the principal investigator for the SOLIS trial of the technology for treating NSBP.
