OBJECTIVE: Chronic neuropathic pain in the groin is a severe condition and difficult to treat. Dorsal root ganglion stimulation (DRGS) covers discrete painful areas precisely with its stimulation power in comparison to spinal cord stimulation (SCS). It was our hypothesis that DRGS provides a long-term relief of chronic groin pain over a period of more than three years. MATERIALS AND METHODS: Patients (age >18 years) with chronic neuropathic groin pain were prospectively examined...

The neurophysiology of gait is complex and involves numerous structures in the central nervous system. Gait disorders occur frequently in Parkinson's disease (PD), and their management may become cumbersome, especially in the more advanced stages. Neuromodulatory treatments, including deep brain stimulation, cortical stimulation and spinal cord stimulation, are reviewed with respect to their effectiveness to improve gait in PD patients. Although positive effects have been reported for all of these procedures, many issues remain in view of methodological heterogeneity, variability in outcome measures and sample size...

BACKGROUND: Although spinal cord stimulation (SCS) therapy has been shown to be efficacious in various pain conditions, the ability for SCS therapy to maintain long-term efficacy has been questioned. OBJECTIVE: The purpose of this study was to investigate whether a loss of efficacy (LOE) phenomenon exists with SCS therapy and to investigate if this phenomenon is more apparent in any specific patient population. STUDY DESIGN: A retrospective, observation chart review was conducted to evaluate the patient response to SCS therapy over time...

Brain plasticity is demonstrated in complex regional pain syndrome (CRPS), although it is unclear how it modulates at different stages of CRPS. The observation that symptoms can progress over time suggests that the pattern of brain changes might also evolve. We measured structural and functional changes as well as sensorimotor integration at early and late stages (ES and LS) of CRPS. Twelve ES patients, sixteen LS patients, and sixteen age- and sex-matched controls were recruited. Gray matter (GM) volume was estimated using voxel-based morphometry...

INTRODUCTION: Spinal cord stimulation (SCS) for the treatment of lower extremity pain is believed to the result of increased activity in the descending inhibitory and decreased activity in the ascending excitatory tracts. Evidence suggests that the analgesia afforded by SCS may be altered using certain neuropathic pain medications that also modulate neurotransmitters in these sensory tracts. We hypothesize that neuropathic pain medications may alter the response to SCS therapy. METHODS: One hundred and fifteen subjects undergoing SCS therapy for lower extremity pain were retrospectively examined...

OBJECTIVES: Methods of energy delivery for traditional spinal cord stimulation (SCS) systems consist of adjusting programming parameters to affect the total charge delivered per unit time. One high electrical charge delivery method being considered is subthreshold high density (HD) programming. To date, there is limited clinical evidence for the efficacy and safety of paresthesia-free HD programming. The aim of this study was to examine the efficacy and safety of HD programming. MATERIALS AND METHODS: A retrospective review was performed on HD-programmed SCS patients with a minimum of one year follow-up...

INTRODUCTION: Spinal cord stimulators (SCS) are indicated for the management of multiple pain states with strong evidence. Recent guidelines recommend discontinuing aspirin or non-steroidal anti-inflammatory drugs (NSAIDs) for the described procedures. The goal of this investigation is to assess the rate of bleeding and neurologic sequelae in patients undergoing SCS trials and implantation. METHODS: This is a retrospective review from 2005 through 2014 of all patients 18 years or older undergoing the following procedures: Percutaneous SCS implantations, SCS revisions, and SCS trials...

Axial symptoms are a late-developing phenomenon in the course of Parkinson's disease (PD) and represent a therapeutic challenge given their poor response to levodopa therapy and deep brain stimulation. Spinal cord stimulation (SCS) may be a new therapeutic approach for the alleviation of levodopa-resistant motor symptoms of PD. Our purpose was to systematically review the effectiveness of SCS for the treatment of motor symptoms of PD and to evaluate the technical and pathophysiological mechanisms that may influence the outcome efficacy of SCS...

UNLABELLED: The objective of this manuscript was to report a case of a patient with extruded pulse generator 3 years after implantation of a spinal cord stimulator system.With the increasing incidence of chronic pain, spinal cord stimulation (SCS) is becoming more commonly utilized by pain physicians. SCS is a generally safe intervention with minimal adverse effects; however, there are risks of complications which practitioners should be aware of prior to and after placement of the SCS...

STUDY DESIGN: Repetitive transcranial magnetic stimulation study. OBJECTIVES: The analgesic effects of repetitive transcranial magnetic stimulation (rTMS) in chronic pain have been the focus of several studies. In particular, rTMS of the premotor cortex/dorsolateral prefrontal cortex (PMC/DLPFC) changes pain perception in healthy subjects and has analgesic effects in acute postoperative pain, as well as in fibromyalgia patients. However, its effect on neuropathic pain in patients with traumatic spinal cord injury (SCI) has not been assessed...

CONTEXT: Spinal cord injury (SCI) affects more than 2.5 million people worldwide, often leading to severe disability. Thus, a proper management of individuals with SCI is required either in the acute or in the post-acute rehabilitative phase. FINDINGS: A 31-year-old man, affected by chronic SCI, underwent two different intensive rehabilitation treatments, including either LokomatPro or a paired LokomatPro-rTMS training. We evaluated the clinical, kinetic, and electrophysiological parameters before and after each training session...

Craniofacial pain, including trigeminal neuralgia, trigeminal neuropathic pain, and persistent idiopathic facial pain, is difficult to treat and can have severe implications for suffering in patients afflicted with these conditions. In recent years, clinicians have moved beyond treating solely with pharmacological therapies, which are generally not very effective, and focused on new interventional pain procedures. These procedures have evolved as technology has advanced, and thus far, early results have demonstrated efficacy in small patient cohorts with a variety of craniofacial pain states...

Electrical stimulation of the dorsal columns (DCs; spinal cord stimulation; SCS) has been proposed to treat chronic neuropathic pain. SCS may activate a dual mechanism that would affect both the spinal cord and supraspinal levels. Stimulation of DCs or DC nuclei (DCN) in animals where neuropathic pain has been induced causes activation of brainstem centers including the periaqueductal gray (PAG), which is involved in the endogenous pain suppression system. Biotinylated dextran-amine (BDA) was iontophoretically injected into the DCN to analyze the ascending projection directed to the PAG...

INTRODUCTION: A shorter delay time from chronic pain diagnosis to spinal cord stimulation (SCS) implantation may make it more likely to achieve lasting therapeutic efficacy with SCS. The objective of this analysis was to determine the impact of pain-to-SCS time on patients' post-implant healthcare resource utilization (HCRU). METHODS: A retrospective observational study was performed using a real-world patient cohort derived from MarketScan(®) Commercial and Medicare Supplemental claims data bases from April 2008 through March 2013...

OBJECTIVE Cervical spinal cord stimulation (cSCS) is used to treat pain of the cervical region and upper extremities. Case reports and small series have shown a relatively low risk of complication after cSCS, with only a single reported case of perioperative spinal cord injury in the literature. Catastrophic cSCS-associated spinal cord injury remains a concern as a result of underreporting. To aid in preoperative counseling, it is necessary to establish a minimum rate of spinal cord injury and surgical complication following cSCS...

INTRODUCTION: The neurophysiological basis of pain relief due to spinal cord stimulation (SCS) and the related cortical processing of sensory information are not completely understood. The aim of this study was to use resting state functional magnetic resonance imaging (rs-fMRI) to detect changes in cortical networks and cortical processing related to the stimulator-induced pain relief. METHODS: Ten patients with complex regional pain syndrome (CRPS) or neuropathic leg pain underwent thoracic epidural spinal cord stimulator implantation...
