AIMS: To evaluate effectiveness of transcutaneous tibial nerve stimulation (TTNS) for treating adults with overactive bladder (OAB) of idiopathic or neurogenic origin, using a systematic review of the literature. METHODS: Systematic searches of four databases were undertaken between 1980 and 2017. Included studies investigated effects of TTNS on OAB. Study selection, data extraction, quality appraisal was performed by two independent reviewers. Narrative analysis was undertaken where meta-analysis was not possible due to study heterogeneity...

When identical stimuli are presented in rapid temporal succession, neural responses to the second stimulation are often weaker than that observed for the first. This phenomenon is termed sensory gating and is believed to be an adaptive feature that helps prevent higher-order cortical centers from being flooded with unnecessary information. Recently, sensory gating in the somatosensory system has been linked to deficits in tactile discrimination. Additionally, studies have linked poor tactile discrimination with impaired walking and balance in individuals with multiple sclerosis (MS)...

INTRODUCTION: We aimed to compare forces evoked by wide-pulse high-frequency (WPHF) neuromuscular electrical stimulation (NMES) delivered to a nerve trunk vs. muscle belly and to assess their test-retest intra- and inter-individual reliability. METHODS: Forces evoked during two sessions with WPHF NMES delivered over the tibial nerve trunk and two over the triceps surae muscle belly were compared. Ten individuals participated in four sessions involving ten 20-s WPHF NMES contractions interspaced by 40 s recovery...

Current neural interface technologies have serious limitations for advanced prosthetic and therapeutic applications due primarily to their lack of specificity in neural communication. An optogenetic approach has the potential to provide single cell/axon resolution in a minimally invasive manner by optical interrogation of light-sensitive reporters and actuators. Given the aim of reading neural activity in the peripheral nervous system, this work has investigated an activity-dependent signaling mechanism in the peripheral nerve...

BACKGROUND: Flexible elastic nails, submuscular plating, and rigid locked intramedullary nails are common methods of fixation for pediatric femur fractures (PFF) in which the fracture table is used to aid reduction. Little is known about complications associated with fracture table application in PFF. The purpose of this study was to determine the incidence and risk factors associated with adverse outcomes related to fracture table application for the treatment of PFF. METHODS: A retrospective chart review of all children (younger than 18 y) treated for a femur fracture with the use of the fracture table between 2004 and 2015 at a single tertiary pediatric hospital was performed...

REVIEW
Amanda S J Chung, Kurt A McCammon
Lower urinary tract symptoms (LUTS) after urethral stricture repair are not uncommon. Urgency has been reported in 40% of men and urge incontinence in 12% of men after anterior urethroplasty. De novo urgency and urge incontinence is seen in 9 and 5% of men, respectively, after urethroplasty. Once a complication of urethroplasty (such as recurrent urethral stricture or diverticulum) has been excluded as a cause, evaluation of LUTS in such patients should focus on differentiating bladder dysfunction (overactive bladder, underactive bladder), from other outlet obstruction (such as benign prostatic obstruction), dysfunctional voiding, or medical causes (such as nocturnal polyuria)...

Chronic exertional compartment syndrome is a rare cause of lower leg pain incurred during sports activities and typically affects young athletes who need to return to their activity level as quickly as possible. Nonoperative treatments are often unsuccessful and fasciotomy of the involved compartment is the treatment of choice. Endoscopically assisted release of the anterior and deep compartments is proven to be safe and effective. Endoscopically assisted deep posterior compartment release via an incision 1 to 3 cm behind the medial tibial border has high risk of injury to the great saphenous and perforating veins and the saphenous nerve...

BACKGROUND: Electrical stimulation of the peripheral nerves has been shown to be effective in restoring sensory and motor functions in the lower and upper extremities. This neural stimulation can be applied via non-penetrating spiral nerve cuff electrodes, though minimal information has been published regarding their long-term performance for multiple years after implantation. METHODS: Since 2005, 14 human volunteers with cervical or thoracic spinal cord injuries, or upper limb amputation, were chronically implanted with a total of 50 spiral nerve cuff electrodes on 10 different nerves (mean time post-implant 6...

OBJECTIVE: Repair of sensorial nerve defect is an important issue on peripheric nerve surgery. The aim of the present study was to determine the effects of sensory-motor nerve bridging on the denervated dermatomal area, in rats with sensory nerve defects, using a neural cell adhesion molecule (NCAM). METHODS: We compared the efficacy of end-to-side (ETS) coaptation of the tibial nerve for sural nerve defect repair, in 32 Sprague-Dawley rats. Rats were assigned to 1 of 4 groups: group A was the sham operated group, group B rats had sural nerves sectioned and buried in neighboring muscles, group C experienced nerve sectioning and end-to-end (ETE) anastomosis, and group D had sural nerves sectioned and ETS anastomosis was performed using atibial nerve bridge...

BACKGROUND: Functional electrical stimulation (FES) can be applied as an assistive and therapeutic aid in the rehabilitation of foot drop. Transcutaneous multi-pad electrodes can increase the selectivity of stimulation; however, shaping the stimulation electrode becomes increasingly complex with an increasing number of possible stimulation sites. We described and tested a novel decision support system (DSS) to facilitate the process of multi-pad stimulation electrode shaping. The DSS is part of a system for drop foot treatment that comprises a custom-designed multi-pad electrode, an electrical stimulator, and an inertial measurement unit...

BACKGROUND: Chronic immune sensory polyradiculopathy (CISP) identifies a progressive acquired peripheral dysimmune neuropathy recognized as a chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) variant. We describe a young woman with a thirteen-year history of CISP with a belated variable response to intravenous immunoglobulin (IVIG) and an almost erratic anticipation of symptoms between IVIG cycles. The association of IVIG and corticosteroids, immunosuppressants, plasmapheresis, did not lead to clinical improvement and was characterized by significant side effects...

Tarsal tunnel syndrome is an entrapment neuropathy of the posterior tibial nerve or its terminal branches within its fibro-osseous tunnel beneath the flexor retinaculum on the medial side of the ankle. The condition is frequently underdiagnosed leading to controversies regarding its epidemiology and to an intense debate in the literature. With the advent of nerve imaging techniques, the diagnostic confirmation and the etiological identification have become more accurate. However, management of this entrapment neuropathy remains challenging because of many intervention strategies but limited robust evidence...

Overactive bladder (OAB) affects millions of people around the world and decreases quality of life for those affected. Over the past two decades, significant advances in treatment have transformed the lives of those with OAB. Sacral neuromodulation (SNM), posterior tibial nerve stimulation (PTNS), and dorsal genital nerve stimulation are the most effective contemporary treatment modalities. New techniques and bio-sensing schemes offer promise to advance therapy beyond what is currently available. Current neuromodulation techniques do not use real-time data from the body or input from the patient...
