Ultra Low Frequency Neuromodulation for Nociceptive Chronic Low Back Pain

This is a prospective, multi-center, randomized, controlled trial in which subjects with chronic, intractable axial low back pain with prominent nociceptive features will be randomized 2:1 into either Ultra Low Frequency (ULF) therapy combined with conventional medical management (CMM) or CMM alone. The purpose of this study is to compare the safety and efficacy of ULF neuromodulation to CMM in Subjects with chronic, intractable axial low back pain with prominent nociceptive features over a 24-month period. Subjects assigned to CMM will continue with further optimization of the best available medical treatments. Subjects assigned to ULF therapy will proceed with a temporary trial phase and be eligible for permanent device implant if they experience at least 50% back pain relief. An option to cross over to the alternative treatment arm will be permitted at the 6-month timepoint for subjects who meet the criteria. The study primary endpoint will be evaluated at 3 months and follow-up will continue for 24 months total.
