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 study aims to describe an ultrasound (US)-guided peripheral nerve stimulation implant technique and describe the effect of high-frequency peripheral nerve stimulation on refractory postherpetic neuralgia. ⋯ We report the implant of a supraorbital peripheral nerve stimulating electrode that utilizes a high-frequency program resulting in sustained suppression of intractable postherpetic neuralgia.

An implantable drug delivery system (IDDS) provides an alternate route of opioid administration for patients with chronic pain. We collected data on systemic opioid use before and after IDDS implantation; patients who successfully discontinued systemic opioids; and physician support of discontinuation. ⋯ IDDS can provide significant and lasting pain relief and an alternate route of delivery compared with systemic opioids with their associated side-effects. We demonstrated that systemic opioid elimination could be accomplished after IDDS implantation in the majority of cases through appropriate patient selection, monitoring, and participation.

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.
