Introduction: To address the need for greater standardization within the field of electrodiagnostic medicine, the Normative Data Task Force (NDTF) was formed to identify nerve conduction studies (NCS) in the literature, evaluate them using consensus-based methodological criteria derived by the NDTF, and identify those suitable as a resource for NCS metrics. Methods: A comprehensive literature s...

OBJECTIVE To evaluate the diagnostic value of the Inlet-to-outlet median nerve area ratio (IOR) in patients with clinically and electrophysiologically confirmed carpal tunnel syndrome (CTS). METHODS Forty-six wrists in 46 consecutive patients with clinical and electrodiagnostic evidence of CTS and forty-four wrists in 44 healthy volunteers were examined with ultrasonography. The cross-section...

7 The nerve anatomy of the upper extremity is studied constantly through surgical findings, electrodiagnostic studies, and cadaveric dissections. Although it is recognized that the anatomy is not changing rapidly, knowledge of the anatomic relationships and their significance is increasing. The purpose of the current study is to provide a comprehensive analysis of the nerve anatomy of the upper...

OBJECTIVE Guillain-Barre Syndrome (GBS) is an acute polyradiculoneuropathy characterized by progressive motor weakness of limbs and areflexia. In this study, our aim was to evaluate the clinical pattern and prognosis of children with Guillain-Barre syndrome. MATERIALS & METHODS This cross-sectional study was conducted in the Pediatric Neurology Unit of Amirkola Children's Hospital, Babol, Ira...

This study was designed to investigate the incidence of lateral root of the ulnar nerve through cadaveric dissection and to analyze its impact on myotomes corresponding to the flexor carpi ulnaris (FCU) assessed by electrodiagnostic study. Dissection of the brachial plexus (BP) was performed in 38 arms from 19 cadavers, and the connecting branches between the lateral cord and medial cord (or be...

Ultrasonographic study is useful for decision making of treatment for focal neuropathy with unusual electrodiagnostic findings. We present a patient with severe acute radial neuropathy with sensory sparing around the distal arm secondary to twisting of the radial nerve following blunt trauma. A 24-year-old man with a 2-week history of left wrist drop and severe pain around the left elbow presen...

Background: Multiple sclerosis (MS) is known to affect essentially the central nervous system; however, peripheral nerve involvement, as an additional cause of disability, has been recently noticed. Objectives: This study was aimed to perform detailed electrodiagnostic assessments in MS patients to evaluate peripheral nervous system involvement. Materials and Methods: A total of eighty MS...

OBJECTIVES To evaluate, in patients with ulnar neuropathy at the elbow (UNE), if ultrasonographic differences in ulnar nerve size correlate with severity score determined by electrodiagnostic studies. METHODS We examined prospectively 38 patients (50 elbows) with UNE. Patients were classified into mild, moderate and severe groups according to electrodiagnostic studies. Cross-sectional areas (...

BACKGROUND AND OBJECTIVE Neonatal bulbar weakness (BW) has various etiologies and a broad prognostic range. We aimed to report outcomes in a large series of children with neonatal BW and explore the association of orofacial electrodiagnostic data with outcome. METHODS We retrospectively reviewed the files of children who presented with facial, lingual, laryngeal, or pharyngeal weakness at bir...

Introduction. Radicular low back pain is one of the most common medical problems. The aim of this study was to evaluate the diagnostic accuracy of MRI and electrodiagnosis in lower extremity radicular pain in relation to history and clinical findings. Methods. In this cross-sectional study, we studied 165 sciatalgic subjects. A comprehensive history and physical examinations were taken from the...
