INTRODUCTION: There is uncertainty as to whether the Guillain-Barré syndrome (GBS) subtypes, acute inflammatory demyelinating polyradiculoneuropathy (AIDP) and acute motor axonal neuropathy (AMAN), can be diagnosed electrophysiologically. METHODS: We prospectively included 58 GBS patients. Electrophysiology was performed at means of 5 and 33 days after disease onset. Two traditional and one recent criteria sets were used to classify studies as demyelinating or axonal...

OBJECTIVE: To determine the cost of medical care in patients with gonarthrosis. MATERIAL AND METHODS: Cost study in patients over 40 years of age with gonarthrosis, diagnosed according to the radiological classification of Kellgren and Lawrence. The average annual cost (euros) was estimated taking the unit cost plus average use of services such as family medicine, imaging, laboratory, electrodiagnosis, orthopedics, hospitalization, physical therapy, surgery, nutrition, preoperative assessment and medication...

Electrodiagnostic (EDX) studies are often very helpful in the diagnosis and management of patients who have or are suspected to have Distal Symmetric Polyneuropathy (DSP). However, EDX studies may not be appropriate in every situation. There are five common scenarios in which EDX studies are likely to be beneficial: (1) determining primary and alternative diagnoses; (2) determining severity, duration and prognosis of disease; (3) evaluating risk of associated problems; (4) determining the effect of medications; and (5) evaluating the effect of toxic exposures...

OBJECTIVES: To assess the usefulness of serial electrophysiology in Guillain-Barré syndrome (GBS) in a multicenter setting and the reasons for change in electrodiagnostic subtypes with serial studies. METHODS: We retrospectively analysed serial electrophysiology of 51 patients with GBS from 4 European centres. Proportions of subtypes were determined at each timing. Individual case analyses were also performed where diagnostic changes occurred with either criteria, to ascertain if changes were due to disease progression or criteria inadequacy...

BACKGROUND: Until recently, the peripheral nervous system (PNS) had been known to be spared in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD). However, some studies of late have reported PNS damage in demyelination diseases of the central nervous system (CNS) such as MS and NMOSD. Although multiple studies have reported characteristics reminiscent of peripheral neuropathy in MS, there have been limited reports in NMOSD. To investigate the incidence and pathology of peripheral neuropathy in NMOSD, we reviewed articles describing such cases including our own case...

OBJECTIVE: Nerve ultrasound (US) data on myelin protein zero (MPZ)-related Charcot-Marie-Tooth disease (CMT) are lacking. To offer a comprehensive perspective on MPZ-related CMTs, we combined nerve US with clinics, electrodiagnosis and histopathology. METHODS: We recruited 36 patients (12 MPZ mutations), and correlated nerve US to clinical, electrodiagnostic measures, and sural nerve biopsy. RESULTS: According to motor nerve conduction velocity (MNCV) criteria, nine patients were categorized as "demyelinating" CMT1B, 17 as "axonal" CMT2I/J, and 10 as dominant "intermediate" CMTDID...

PURPOSE: It is unclear whether the muscular changes in mechanically-ventilated traumatic brain injury patients (TBI) are only associated with disuse or additionally to neuromuscular electrophysiological disorders (NED). The correlation between muscle atrophy and NED may affect functional outcomes and rehabilitation programs significantly. MATERIAL AND METHODS: An observational study was performed to investigate the presence of NED and muscle atrophy in TBI patients undergoing mechanical ventilation...

INTRODUCTION: We sought to investigate the reliability of a new electrodiagnostic method for identifying Electrodiagnosis of Brachial Plexus & Vessel Compression Syndrome (BPVCS) in rats that involves the application of transcranial electrical stimulation motor evoked potentials (TES-MEPs) combined with peripheral nerve stimulation compound muscle action potentials (PNS-CMAPs). RESULTS: The latencies of the TES-MEP and PNS-CMAP were initially elongated in the 8-week group...

To date, no previous study has evaluated the efficacy of topical Lavendula stoechas (Lavender) oil in CTS patients. PURPOSE OF THE STUDY: To investigate the effectiveness of topical Lavender essential oil in pain intensity, isometric pinch strength, electrophysiological features, and functional status of patients with mild to moderate CTS...

OBJECTIVE: The electrodiagnosis of polyneuropathy (PNP) may benefit from examination using near-nerve needle technique (NNT) and from inclusion of distal nerves. This study compared the diagnostic utility of distal nerve conduction studies (NCS) and NNT recording. METHODS: Bilateral NNT and surface recording of the sural nerve and surface recording of the dorsal sural and medial plantar nerves were prospectively done in 91 patients with clinically suspected PNP...

OBJECTIVE: The purpose of the study was to evaluate the diagnostic value of both inching method through the electrodiagnostic test and ultrasonographic assay in localizing the site of entrapment in patients with symptoms and signs of carpal tunnel syndrome. DESIGN: Thirty-two hands with confirmed carpal tunnel syndrome through electrodiagnostic test and 30 hands as control group were enrolled. For both groups, sensory and motor latencies by inching technique and cross-sectional area by ultrasonography were measured at the inching points...

We reported a 32-year-old man who was a sporadic case of myotonic syndrome with muscle stiffness or transient weakness of limbs upon initiating movements after rest. On examination, he showed painless myotonia with warm-up phenomenon, Hercules-like hypertrophic musculature and myotonic discharges in EMG. The clinical findings resembled to those of Becker disease rather than Thomsen disease. But electrodiagnosis suggested sodium channel myotonia instead of chloride channelopathy. Genetic testing detected a novel missense mutation (p...

OBJECTIVE: To optimize the electrodiagnosis of Guillain-Barré syndrome (GBS) subtypes at first study. METHODS: The reference electrodiagnosis was obtained in 53 demyelinating and 45 axonal GBS patients on the basis of two serial studies and results of anti-ganglioside antibodies assay. We retrospectively employed sparse linear discriminant analysis (LDA), two existing electrodiagnostic criteria sets (Hadden et al., 1998; Rajabally et al., 2015) and one we propose that additionally evaluates duration of motor responses, sural sparing pattern and defines reversible conduction failure (RCF) in motor and sensory nerves at second study...

AIM: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy and is one of the most common requests for electrodiagnosis. We aimed to note the relationship of subjective symptom severity of CTS, with objective electrophysiological severity and psychological status of patients. PATIENTS AND METHODS: One hundred and forty-four consecutive patients of CTS referred to neurophysiology laboratory of a tertiary care hospital over 1 year were prospectively studied...

OBJECTIVE: To investigate the relationship between electrodiagnosis and various ultrasonographic findings of carpal tunnel syndrome (CTS) and propose the ultrasonographic standard that has closest consistency with the electrodiagnosis. METHODS: Ultrasonography was performed on 50 female patients (65 cases) previously diagnosed with CTS and 20 normal female volunteers (40 cases). Ultrasonography parameters were as follows: cross-sectional area (CSA) and flattening ratio (FR) of the median nerve at the levels of hamate bone, pisiform bone, and lunate bone; anteroposterior diameter (AP diameter) of the median nerve in the carpal tunnel; wrist to forearm ratio (WFR) of median nerve area at the distal wrist crease and 12 cm proximal to distal wrist crease; and compression ratio (CR) of the median nerve...

INTRODUCTION: In this study we propose electrodiagnostic criteria for early reversible conduction failure (ERCF) in axonal Guillain-Barré syndrome (GBS) and apply 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) a 50% increase in amplitude of distal compound muscle action potentials or sensory nerve action potentials; or (ii) resolution of proximal motor conduction block with an accompanying decrease in distal latencies or compound muscle action potential duration or increase in conduction velocities...
