The mechanism of action of spinal cord stimulation (SCS) is poorly understood and the success of treatment can depend on factors beyond the technical aspects of implantation. The aim of this retrospective analysis is the identification of preimplantation psychological values that may predict outcome of SCS treatment. ⋯ Sleep interference appears to be an independent risk factor for unsuccessful SCS therapy.

Spinal cord stimulation (SCS) revision surgery remains common, with a negative impact on cost-effectiveness and outcomes. The primary goal of this report was to retrospectively study the need for revision surgery in a cohort of complex regional pain syndrome type I (CRPS-1) patients with newly implanted cervical surgical paddle leads, focusing on a method of implantation to reduce the need for revision surgery. ⋯ This study is the first to report on: 1) cervical electrode implantation with no anchoring; and 2) cervical paddle lead implantation (including three-column paddles) performed under conscious sedation. The specific method of nonanchoring of the paddle implants under conscious sedation may have contributed to low electrode lead revision rates.

Multicenter Study
Chronic Low Back Pain: Restoration of Dynamic Stability.
Electrical stimulation for multifidus muscle contraction is a novel approach for treating chronic low back pain (CLBP). A multicenter, open-label feasibility study investigated this modality in patients with continuing CLBP despite medical management and no prior back surgery and no known pathological cause of CLBP. ⋯ Episodic stimulation to induce LM contraction can reduce CLBP and disability, improve quality of life and enable return to work. A dedicated lead design to reduce risk of migration is required.

Randomized Controlled Trial
The New Portable Transcutaneous Electrical Nerve Stimulation Device Was Efficacious in the Control of Primary Dysmenorrhea Cramp Pain.
Transcutaneous electrical nerve stimulation (TENS) is an established method for pain relief in dysmenorrhea. A feasible advantage would be the study of a portable device. The purpose of the study was to evaluate the effectiveness and safety of a new portable TENS device (TANYX®) for menstruation cramps. ⋯ The portable, disposable, active TENS device induced a prompt onset of pain relief and improved the quality of life, without adverse effects, in patients with painful cramps associated with dysmenorrhea.

The objective of this retrospective study was to study the frequency of intraoperative neuromonitoring (IONM) alerts during the spinal cord stimulator (SCS) placement surgery, postoperative neurological complications and effectiveness of Somatosensory evoked potential (SSEP) and electromyography (EMG) methods to determine laterality of the SCS lead placement. ⋯ IONM is an effective tool in detecting potential neurological event and facilitating lead placement and potentially avoiding revision surgery.
