Electrodiagnostic testing has proved useful in helping to establish the diagnosis of amyotrophic lateral sclerosis by eliminating possible disease mimics and by demonstrating abnormalities in body areas that are clinically unaffected. Electrodiagnosis begins with an understanding of the clinical features of the disease, because clinical correlation is essential. To improve the sensitivity of th...

Piriformis Syndrome (PS) is an uncommon, controversial neuromuscular disorder that is presumed to be a compression neuropathy of the sciatic nerve at the level of the piriformis muscle (PM). The diagnosis is hampered by a lack of agreed upon clinical criteria and a lack of definitive investigations such as imaging or electrodiagnostic testing. Treatment has focused on stretching, physical thera...

A case fulfilling the criteria for the diagnosis of diabetic amyotrophy is reported. Based on the clinical and electrodiagnostic features, it is concluded that diabetic amyotrophy is a recognizable clinical entity that can be differentiated from other diabetic neuropathies. The site of the lesion and the pathogenesis in diabetic amyotrophy remain controversial. The course of the illness is vari...

Introduction It is unknown how often patients with electrodiagnostic evidence of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), a potentially treatable condition, present distal symmetric polyneuropathy (DSP) phenotype. Methods We reviewed the records who presented to our laboratory between January 1, 2011 December 31, 2019 and fulfilled criteria for CIDP identify those senso...

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a diagnosis based upon clinical signs and symptoms, electrodiagnostic studies, lumbar puncture, laboratory tests, and, occasionally, nerve biopsy. CIDP is characterised by a slowly progressive or relapsing course.'2 To our knowledge no case of CIDP meeting current diagnostic criteria' has been associated with intracranial hypertension....

The idiopathic hypereosinophilic syndrome (HES) represents a leukoproliferative disorder, characterized by unexplained prolonged eosinophilia (>6 months) and evidence of specific organ damage. So far, the peripheral neuropathy associated with skin manifestations of HES has not been reported in the dermatologic literature although the incidence of peripheral neuropathy after HES ranges from 6~52...

Introduction: The purpose of this study was to develop an evidence-based guideline for the use of neuromuscular ultrasound in the diagnosis of carpal tunnel syndrome (CTS). Methods: Two questions were asked: (1) What is the accuracy of median nerve cross-sectional area enlargement as measured with ultrasound for the diagnosis of CTS? (2) What added value, if any, does neuromuscular ultrasound p...

INTRODUCTION There have been 15 formal sets of criteria published for the diagnosis of CIDP. No study to date has compared the sensitivity and specificity of all published criteria in the same patient population. METHODS We conducted a retrospective chart review of patients with CIDP (n = 56) and controls with diabetic polyneuropathy (n = 37) or amyotrophic lateral sclerosis (n = 39) who were...

Background:  This study tested the null hypothesis that nonoperatively treated patients would not show disease progression of carpal tunnel syndrome (CTS) over time according to median nerve distal motor latency (DML) on two electrodiagnostic tests.   Methods:  This retrospective study analyzed sixty-two adult nonoperatively treated patients who were diagnosed with CTS confirmed by a minimum of...
