Clinical Electrodiagnosis

Clinical features and electrodiagnosis of ulnar neuropathies.

In this review, we delineate clinical, electrodiagnostic, and radiographic features of ulnar mononeuropathies. Ulnar neuropathy at the elbow (UNE) is most commonly due to lesions at the level of the retroepicondylar groove (RTC), with approximately 25% at the humeroulnar arcade (HUA). The term 'cubital tunnel syndrome' should be reserved for the latter. The diagnostic accuracy of nerve conducti...

Ophthalmic Electrodiagnosis

Visual electrodiagnosis in glaucoma screening: a clinical study.

BACKGROUND The aim of the present study was to investigate the value of pattern visual-evoked potentials (pVEP) and pattern electroretinograms (pERG) in early glaucoma diagnosis. MATERIALS AND METHODS Thirty-eight eyes of 38 patients were included. Patients were classified into normal control (NC) and glaucoma patient (GP) groups. Patients underwent a detailed clinical ophthalmic examination ...

Electrodiagnosis of lumbar radiculopathy.

The evaluation of patients with suspected lumbar radiculopathy is one of the most common reasons patients are referred for electrodiagnostic testing. The utility of this study depends on the expertise of the physician who plans, performs, and completes the study. This article reviews the strengths and weaknesses of electrodiagnosis to make this diagnosis, as well as the clinical reasoning of ap...

Electrodiagnosis in Cranial Botulism

Botulism is an acute neurologic disorder that causes potentially life-threatening neuroparalysis resulting in weakness and laccid paralysis. In addition to the autonomic nervous system, botulism may involve only the cranial nerves, thus posing special diagnostic problems. Almost all cranial nerves are not easily testable. The anatomical and physiological characteristics of the spinal accessory ...
