Recurrent median neuropathy is an uncommon injury that can be commonly mistaken for other pathological causes. It is important to be aware of the potential causes and symptoms of injury as delay in diagnosis can lead to permanent decrease in hand function and disability. This case is a description of a 33-year-old male patient who previously presented with radicular symptoms and had complete resolution of his pain after a C7 selective nerve root block. Several months after presentation, he developed significant thenar atrophy, localized pain, and weakness associated with weight lifting activities...

OBJECTIVE: We proposed electrodiagnostic criteria for early reversible conduction failure (ERCF) in axonal Guillain-Barré syndrome (GBS) and applied them to a cohort of GBS patients. METHODS: Serial nerve conduction studies (NCS) were retrospectively analyzed in 82 GBS patients from 3 centers. The criteria for the presence of ERCF in a nerve were i) 50% increase in amplitude of distal compound muscle action potentials or sensory nerve action potentials, or ii) resolution of proximal motor conduction block with accompanying decrease in distal latencies or compound muscle action potential duration or increase in conduction velocities...

BACKGROUND: Dislocation of the ulnar nerve (UN) occurs in a subset of patients with ulnar neuropathy. Electrodiagnostic and magnetic resonance imaging (MRI) studies are performed to support the clinical diagnosis. We report the case of a patient with ulnar neuropathy with normal electrodiagnostic and MRI studies but with ultrasound (US) showing UN dislocation, which prompted successful treatment by UN submuscular transposition. CASE DESCRIPTION: A healthy 15 year-old female softball player presented with right medial elbow pain and paresthesias of the fourth and fifth digits...

Carpal tunnel syndrome, the most common entrapment neuropathy of the upper extremity, is caused by compression of the median nerve as it travels through the carpal tunnel. Classically, patients with the condition experience pain and paresthesias in the distribution of the median nerve, which includes the palmar aspect of the thumb, index and middle fingers, and radial half of the ring finger. Additional clues include positive physical examination findings, such as the flick sign, Phalen maneuver, and median nerve compression test...

Objectives The aim of this study was to evaluate the development of impaired median nerve function in relation to hand-intensive seasonal work. We hypothesized that at end-season, median nerve conduction would be impaired and then recover within weeks. Methods Using nerve conduction studies (NCS), we examined median nerve conduction before, during, and after engaging in 22 days of mink skinning. For a subgroup, we used goniometry and surface electromyography to characterize occupational mechanical exposures...

Introduction Recovery from Parsonage-Turner syndrome (PTS) is generally favorable, although recovery times have varied, in part because there are no universally-accepted outcome measures. This study describes the electrodiagnostic natural history of this condition based on objective electrodiagnostic testing, and proposes that complete electrodiagnostic recovery can be seen as early as 1 year. Methods Twenty-six subjects with 29 affected nerves confirmed as PTS were followed every 3 months for electrodiagnostic testing, or until full reinnervation was confirmed...

INTRODUCTION: Clinicians who treat nerve and muscle disorders may be asked to evaluate patients who have unilateral or bilateral scapular winging. Traditionally, this evaluation has relied upon a thorough history, physical examination, and electrodiagnostic testing to localize the cause of winging and detect the underlying neuromuscular pathology. Neuromuscular ultrasound has emerged as a non-invasive technique that can be used for structural evaluation of nerve and muscle abnormalities...

Mark A Ferrante, Nicole D Ferrante
The thoracic outlet syndromes (TOSs) are a group of etiologically and clinically distinct disorders with 1 feature in common: compression of 1 or more neurovascular elements as they traverse the thoracic outlet. The medical literature reflects 5 TOSs: arterial, venous, traumatic neurovascular, true neurogenic, and disputed. Of these, the first 4 demonstrate all of the features expected of a syndrome, whereas disputed TOS does not, causing many experts doubt its existence altogether. Thus, some categorize disputed TOS as cervicoscapular pain syndrome rather than as a type of TOS...

BACKGROUND: Peripheral nerve injury is a common and important cause of morbidity and disability in patients who have suffered a traumatic injury, particularly younger people. Various different injuries can result in damage to specific nerves. In patients with multiple trauma, the prevalence of peripheral nerve injury is estimated at 2.8%, but can reach 5% with the inclusion of brachial plexus involvement. Physical examination, as well as the origin and location of the trauma, can indicate the nerve involved and the type of nerve damage...

Celiac disease has been associated with several neurologic disorders which may result from micronutrient deficiencies, coexisting autoimmune conditions, or gluten sensitivity. Copper deficiency can produce multiple neurologic manifestations. Myeloneuropathy is the most common neurologic syndrome and it is often irreversible, despite copper replacement. We report the case of a 55-year-old man who presented with progressive proximal limb weakness and weight loss in the setting of untreated celiac disease without gastrointestinal symptoms...

Diagnosis of carpal tunnel syndrome (CTS) is frequently confirmed by performing nerve conduction studies. Previous studies demonstrated that abnormal nerve conduction study (NCS) is suggestive of CTS among asymptomatic individuals. However, previous studies included individuals with risk factors for the syndrome. A NCS was performed on the median and ulnar nerves in 130 healthy individuals. About 15% of individuals in this study demonstrated electrodiagnostic evidence of carpal tunnels syndrome. Four cases have shown signs of isolated median neuropathy with normal median sensory component...

INTRODUCTION: Different hypotheses have been proposed for the pathophysiology of posterior interosseous nerve (PIN) palsy, namely compression, nerve inflammation, and fascicular constriction. We hypothesized that critical reinterpretation of electrodiagnostic (EDX) studies and MRIs of patients with a diagnosis of PIN palsy could provide insight into the pathophysiology and treatment. MATERIALS AND METHODS: We retrospectively reviewed patients with a diagnosis of nontraumatic PIN palsy and an upper extremity EDX and MRI...

SeSAME/EAST syndrome is a multisystemic disorder in humans, characterised by seizures, sensorineural deafness, ataxia, developmental delay and electrolyte imbalance. It is exclusively caused by homozygous or compound heterozygous variations in the KCNJ10 gene. Here we describe a similar syndrome in two families belonging to the Malinois dog breed, based on clinical, neurological, electrodiagnostic and histopathological examination. Genetic analysis detected a novel pathogenic KCNJ10 c.986T>C (p.(Leu329Pro)) variant that is inherited in an autosomal recessive way...

Distal symmetric polyneuropathy (DSP) is a common condition where limited diagnostic evaluation is usually required. We present a case story of a 50-year-old male who had symptoms of DSP, but electrodiagnostic testing suggested a more proximal lesion, and magnetic resonance imaging showed a spinal nerve root schwannoma. The patient recovered completely after surgery. This case exemplifies relevant use of electrodiagnostic testing. Based on a recent review, we briefly mention atypical features which should prompt further testing, emphasizing that evaluation should be reserved to a limited group of patients...

BACKGROUND: Carpal tunnel release is the most common upper-limb surgical procedure performed annually in the U.S. There are 2 surgical methods of carpal tunnel release: open or endoscopic. Currently, there is no clear clinical or economic evidence supporting the use of one procedure over the other. We completed a cost-minimization analysis of open and endoscopic carpal tunnel release, testing the null hypothesis that there is no difference between the procedures in terms of cost. METHODS: We conducted a retrospective review using a private-payer and Medicare Advantage database composed of 16 million patient records from 2007 to 2014...
