A Study to Compare HF10 Therapy Combined with Conventional Medical Management (CMM) to CMM Alone in the Treatment of Non-Surgical Refractory Back Pain


About this study

The purpose of this study is to document the safety, clinical effectiveness and cost-effectiveness of high-frequency HF10™ Therapy, delivered through the Senza system, in subjects with chronic refractory back pain (with or without leg pain) who are not considered candidates for spine surgery. This study is a multi-center, prospective, randomized study to compare the two treatment groups.
