Interspinous Process Decompression With The Superion Spacer For Lumbar Spinal Stenosis: Real-World Experience From A Device Registry.

Background: Interspinous process decompression (IPD) with stand-alone spacers has demonstrated excellent long-term clinical benefit for patients with lumbar spinal stenosis (LSS).

Methods: IPD used the Superion Indirect Decompression System (Vertiflex, Carlsbad, CA, USA). Perioperative and clinical data were captured via a registry for patients treated with IPD for LSS with intermittent neurogenic claudication.

Percutaneous Rupture of a Symptomatic Facet Joint Synovial Cyst Using 2-Needle Distention.

Objective: This case report calls attention to an alternative approach for management of a symptomatic facet joint synovial cyst. We describe a patient with a symptomatic facet joint synovial cyst who failed an attempted percutaneous rupture using a single-needle technique. This patient was subsequently successfully managed with percutaneous rupture using a 2-needle technique.

Peripheral nerve field stimulation for the management of localized chronic intractable back pain: results from a randomized controlled study.

Objectives: Improved device technology has caused a renewed interest in peripheral nerve field stimulation (PNfS). This study sought to obtain preliminary estimates of the safety and efficacy of PNfS in patients with localized chronic intractable pain of the back.

Materials And Methods: This Institutional Review Board-approved, prospective, randomized, controlled, crossover study consisted of two phases.

Stimulation of the peripheral nervous system for the painful extremity.

Peripheral nerve stimulation and, recently, peripheral nerve field stimulation are excellent options for the control of extremity pain in instances where conventional methods have failed and surgical treatment is ruled inappropriate. New techniques, ultrasound guidance, smaller generators, and task-specific neuromodulatory hardware and leads result in increasingly safe, stable and efficacious treatment of pain in the extremities. Peripheral nerve stimulation has shown to be an increasingly viable option for many painful conditions with neuropathic and possibly nociceptive origins.

Peripheral nerve stimulation for the treatment of truncal pain.

Neuromodulation practitioners increasingly recognize the potential for peripheral nerve field stimulation (PNfS) to treat pain originating from the trunk. Conditions resulting in truncal pain that may respond to PNfS include cervical and lumbar postlaminectomy syndrome, inguinal neurapraxia, post-herpetic neuralgia, and post-thoracotomy pain. The focus of this chapter is to review the mechanism of action in PNfS, patient selection factors, programming strategies, and technical considerations.

Cervical nerve root stimulation. Part I: technical aspects and normal data.

Objective: Cervical nerve root stimulation (CRS) is a technique of assessing the proximal segments of motor axons destined to upper extremity muscles. Few studies report normal values. The objective was to determine CMAP onset-latencies and CMAP amplitude, area, and duration changes in healthy controls for the abductor pollicis brevis (APB), abductor digiti minimi (ADM), biceps, and riceps muscles.

Neurophysiologic findings in early acute inflammatory demyelinating polyradiculoneuropathy.

Background: Patients with early acute inflammatory demyelinating polyradiculoneuropathy (AIDP) may not meet the current neurophysiologic criteria.

Objective: To document neurophysiologic findings in early AIDP.

Methods: Clinical and neurophysiologic data from 38 AIDP patients, assessed within 10 days of symptom onset were reviewed.

Effects of treadmill walking speed on lateral gastrocnemius muscle firing.

Objective: To study the electromyographic profile--including ON, OFF, and peak timing locations--of the lateral gastrocnemius muscle over a wide range of walking speeds (0.5-2.1 m/sec) in healthy young adults.

Influence of poststroke urinary incontinence on disability: the nursing home setting.

Objective: To characterize the association of poststroke urinary incontinence with disability progression in nursing home residents.

Design: In this prospective cohort study, the Minimum Data Set from the State of New York between 1994 and 1997 was utilized. From a pool of over 240,000 potential subjects, 500 met inclusion/exclusion criteria.
