BACKGROUND Current electrodiagnostic criteria for chronic inflammatory demyelinating polyneuropathy (CIDP) are research oriented favoring specificity over sensitivity. Application of such criteria in clinical practice may miss the diagnosis in potentially treatable patients. OBJECTIVES To analyze the electrophysiologic abnormalities in a cohort of patients with clinically defined CIDP, to com...

BACKGROUND Carpal tunnel syndrome (CTS) is a common occupational disorder associated with repetitive manual work. Little information exists about the possible relation between the variation of biomechanical hand/wrist exposure and the development of symptoms and median nerve conduction values. AIMS To investigate the prevalence of CTS in a group of workers exposed to intensive use of the hand...

This article reviews the use of electrodiagnostic testing in disorders of neuromuscular transmission and discusses the differences between various presynaptic and postsynaptic disorders. Attention is paid to quality control issues that influence the sensitivity of repetitive nerve stimulation and single fiber electromyography. Electrodiagnostic testing, when used as an extension of the clinicia...

This article reviews the usefulness of the electrodiagnostic examination in patients who have suspected cervical and lumbosacral radiculopathy. This study can verify the presence and severity of radiculopathy, determine which levels are involved, and provide an electrodiagnostic correlate to imaging abnormalities. A practical approach for conducting the nerve conduction portion and needle elect...

CASE DESCRIPTION A 2-year-old spayed female domestic shorthair cat was examined because of bilateral thoracic limb weakness of acute onset. CLINICAL FINDINGS Clinical signs included muscle atrophy, paresis, depressed spinal reflexes, hyperesthesia of the thoracic limbs, and reduced jaw muscle tone. Pelvic limb reflexes were normal. Results of a neurologic examination were suggestive of multif...

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...

We describe the clinical and electrodiagnostic features of 8 infants who showed no visual responsiveness and were thought to be severely visually impaired on initial examination. Subsequently all children developed normal visual capabilities and the previously abnormal visually evoked potentials became normal. The clinical and electrodiagnostic features of these infants suggest that they suffer...

OBJECTIVE To determine the prevalence and related characteristics of carpal tunnel syndrome (CTS) in orchardists and to investigate the association between electrodiagnostic severity and physical examinations. METHODS Between July 2013 and September 2014, 377 subjects (174 men and 203 women) visited the Gyeongsang National University Hospital's Center for Farmer's Safety and Health. All the s...

Carpal tunnel syndrome is the most common entrapment neuropathy, and its risk of occurrence in the presence of repetitive, forceful angular hand movements, or vibration, is common. It is critical to make the diagnosis based on appropriate clinical history and findings and with corroborating electrodiagnostic studies. Conservative management should be undertaken with the goal of maintaining empl...
