Multi-Center Study of SPRINT® PNS System for Chronic Low Back Pain Demonstrates Clinically Significant Improvements in Pain and Quality of Life

CLEVELAND, July 12, 2021 – In the largest, most rigorous study to date using the SPRINT® PNS System for chronic axial low back pain (LBP), patients that failed to find relief from at least two different prior LBP treatments (e.g., opioids, over-the-counter analgesics, physical therapy), were treated with the SPRINT PNS System targeting the lumbar medial branch nerves for 60 days.

The multicenter study, recently published in the journal Pain Practice, supports previous research on percutaneous PNS as an effective option in addressing long-term pain without the need for a permanent implant.

The primary endpoint of the study was the percent of participants who experienced a clinically significant reduction in average pain intensity at the end of the 60-day treatment compared to baseline.

  • 73 percent of participants experienced a clinically significant reduction in average pain intensity with an average reduction in pain intensity of 58 percent among this group.
  • Pain relief was sustained through the last follow-up at 14 months in the majority of those who completed long-term follow-up.
  • Participants also reported substantial and statistically significant improvements in secondary endpoints including changes in health-related Quality of Life (QoL), patient global impression of change, and depression.
    • 91 percent reported QoL improvements with 59 percent defining their quality of life as “Much Improved” or “Very Much Improved.”

“This study represents a significant step in the ongoing evolution of the SPRINT PNS System as a first-line neurostimulation treatment for patients and as an important solution for those who have tried and failed to find relief using other approaches for their low back pain,” said Christopher Gilmore, MD, of the Carolinas Pain Institute who was lead author of the study. “This multicenter study included a range of participating physicians and clinical care settings including large academic institutions and private practices, in urban as well as rural locations. Seeing positive generalized outcomes across diverse patient profiles is encouraging and rewarding as we strive to provide relief for a huge patient population struggling with low back pain seeking an effective and minimally-invasive solution.”
