OBJECTIVE To examine the sensitivity of the 3 proposed electrodiagnostic (EDX) criteria for demyelination, the sensitivity and specificity of the proposed Ad Hoc Subcommittee of the American Academy of Neurology AIDS [Acquired Immunodeficiency Syndrome] Task Force histologic criteria (AAN criteria), the degree of agreement among these criteria, and the diagnostic value of sural nerve histologic...

OBJECTIVE To determine the utility of the flick maneuver (flicking motion of hands and wrists when most symptomatic) in the clinical evaluation of carpal tunnel syndrome (CTS). DESIGN Review of standardized data collection on 142 subjects referred for electrodiagnostic evaluation of possible CTS at a university hospital electrodiagnostic clinic. Subjects were first clinically evaluated with t...

OBJECTIVE To investigate the injury mechanism in patients who had peroneal neuropathy after a tibio-fibular fracture and the correlation between tibio-fibular fracture location and the severity of the peroneal neuropathy by using electrodiagnosis. METHOD Thirty-four patients with peroneal neuropathy after a tibio-fibular fracture were recruited for this study. Their medical records, radiologi...

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...

In the present study, the thenar muscles were evaluated using magnetic resonance imaging (MRI), in addition, the correlations between thenar muscle changes, clinical findings and electrodiagnostic results from patients with carpal tunnel syndrome were investigated. The subjects were 13 patients (17 wrists) who were clinically diagnosed with carpal tunnel syndrome. In all patients, a medical his...

Electrodiagnostic data have not been previously reported in tabes dorsalis. A patient with tabes dorsalis is described whose nerve conduction studies and median nerve somatosensory evoked responses (SEPs) were normal. H-reflexes were absent. SEPs of the tibial nerve suggested posterior column dysfunction. These electrodiagnostic findings correlate precisely with the known pathology of tabes dor...
