NCT04693650

Brief Summary

This study is a prospective, multi-site, randomized, shamcontrolled, double-blind trial with one-way crossover designed to assess the effectiveness and safety of the Gimer NeuroBlock SCS Trialing System for the treatment of chronic back pain and/or lower limb pain. The NeuroBlock SCS Trialing System is an ultra-high frequency SCS device for the treatment of patients with chronic back pain and/or lower limb pain who are refractory to conservative pain management. After screening procedures, eligible subjects will enter the study which is comprised of a 1-week randomized testing period, a 1-week follow-up period and 2-week observation period.
