Effect of Restorative Neurostimulation on Major Drivers of Chronic Low Back Pain Economic Impact.
High-impact chronic low back pain (CLBP) correlates with high healthcare resource utilization. Therapies that can alter impact status may provide beneficial long-term economic benefits. An implantable restorative neurostimulation system (ReActiv8, Mainstay Medical) designed to over-ride multifidus inhibition to facilitate motor control restoration, thereby resolving mechanical low back pain symptoms, has shown significant durable clinical effects in moderately and severely impacted patients. ⋯ In addition to clinically meaningful improvements in pain and function with long-term durability, the overwhelming majority of patients transitioned from a high- to a no- or low-impact CLBP state. This is typically associated with significantly lower healthcare-utilization levels. The of recovery trajectory is consistent with a restorative mechanism of action and suggests that over the long term, the improvement in these health states will be maintained.

Randomized Controlled Trial Multicenter Study Comparative Study
Spinal Cord Stimulation With Additional Peripheral Nerve/Field Stimulation vs Spinal Cord Stimulation Alone on Back Pain and Quality of Life in Patients With Failed Back Surgery Syndrome.
Persistent spinal pain syndrome (PSPS) or failed back surgery syndrome (FBSS) refers to new or persistent pain following spinal surgery for back or leg pain in a subset of patients. Spinal cord stimulation (SCS) is a neuromodulation technique that can be considered in patients with predominant leg pain refractory to conservative treatment. Patients with predominant low back pain benefit less from SCS. Another neuromodulation technique for treatment of chronic low back pain is subcutaneous stimulation or peripheral nerve field stimulation (PNFS). We investigated the effect of SCS with additional PNFS on pain and quality of life of patients with PSPS compared with that of SCS alone after 12 months. ⋯ The Clinicaltrials.gov registration number for the study is NCT01776749.

Randomized Controlled Trial Multicenter Study
Comparison of the effectiveness of ultrasound-guided versus fluoroscopy-guided medial lumbar bundle branch block on pain related to lumbar facet joints: a multicenter randomized controlled non-inferiority study.
The aim of this multicenter randomized interventional prospective study was to compare the ultrasound (US)-guided lumbar medial branch block (LMBB) with the fluoroscopy (FS)-guided LMBB in terms of analgesic efficacy and disability in the setting of the treatment of pain arising from the lumbar facet joints (LFJ). ⋯ The medial lumbar bundle branch block under ultrasound-guidance is not inferior to the fluoroscopy-guidance procedure in effectively alleviating pain arising from the facet joints. Considering that this ultrasound technique has the benefit of an irradiation-free, real-time procedure, it can be considered as an effective alternative to the fluoroscopy-guided technique.

Multicenter Study
Early Experience With a Novel Miniaturized Spinal Cord Stimulation System for the Management of Chronic Intractable Pain of the Back and Legs.
A novel, spinal cord stimulation (SCS) system with a battery-free miniaturized implantable pulse generator (IPG) was used in this feasibility study. The system uses an external power source that communicates bidirectionally with the IPG (< 1.5 cm3). Human factors, subject comfort, and effects on low back and leg pain were evaluated in this first-in-human study. ⋯ The Clinicaltrials.gov registration number for the study is ACTRN12618001862235.

Multicenter Study Observational Study
Prospective observational study investigating the predictive validity of the STarT Back tool and the clinical effectiveness of stratified care in an emergency department setting.
To determine the predictive validity of the STarT Back tool (SBT) undertaken at baseline and 6 weeks to classify Emergency Department (ED) patients with LBP into groups at low, medium or high risk of persistent disability at 3 months. A secondary aim was to evaluate the clinical effectiveness of pragmatic risk-matched treatment in an ED cohort at 3 months. ⋯ Disability at baseline and SBT administered at 6 weeks more accurately predicted disability at 3 months than SBT at baseline in an ED population.
