Peripheral nerve hyperexcitability is a rare disorder characterized by spontaneous motor unit activity. Although peripheral seen in multiple immune-mediated neurological conditions, an association with dermatomyositis has rarely been reported. We present 65-year-old woman serological and muscle biopsy features of who also developed marked hypertrophy, stiffness, delayed relaxation along electro...

Background and Aim: The present study aimed to use the median nerve Compound Muscle Action Potential (CMAP) amplitude by stimulation at palm instead of Abductor Pollicis Brevis (APB) needle Electromyography (EMG) for determining axonal loss in patients with Carpal Tunnel Syndrome (CTS). Methods Materials/Patients: This was performed on 180 CTS referred Electrodiagnostic (EDX) Center, Poursina H...

Advances in ultrasound technology have made it possible to gain higher spatial resolution and even depict nerves with excellent visual quality. In this article, the literature concerning sonography in the diagnosis of carpal tunnel syndrome (CTS) is critically reviewed. We searched Medline for studies on sonography in the diagnosis of CTS and used the reference lists of the articles found. A to...

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 (...

The anterior horn cell diseases, with the exception of polio, are progressive degenerative diseases of the motor neurons. These disorders include SMA types I to III in children and familial and sporadic ALS and its variants (PMA, PLS, and PBP), Kennedy's disease, and SMA type IV in adults. The electrodiagnostic study is a crucial step in the diagnostic process for all of these disorders. In gen...
