Type 2 superior labral anterior to posterior (SLAP) lesion is a common cause of shoulder pain requiring surgical operation. SLAP tears are often associated with paralabral cysts, but they rarely cause nerve compression. However, we experienced two cases of type 2 SLAP-related paralabral cysts at the spinoglenoid notch which were confirmed as isolated nerve entrapment of the infraspinatus branch...

Needle electromyography (EMG) and nerve conduction studies (NCSs) performed by a physician (MD or DO) with the appropriate education, training, and experience are used to evaluate patients with neuromuscular (NM) diseases and diagnose the presence, distribution, and severity of nerve, NM junction, and muscle pathology.1 After needle EMG and NCSs studies are completed, it is necessary to prepare...

The Department of Physical Medicine, Rehabilitation and Electrodiagnosis of Shaheed Beheshti Medical University in collaboration with the Iranian Society of Physical Medicine and Rehabilitation (ISPMR) held the 1st Congress of Electrodiagnostic Medicine in Peripheral Nerve Lesions on December 21-22, 2006. Electrodiagnostic medicine is a specific branch of medicine used by specialist physicians ...

Objective: This study investigated the correlations between magnetic resonance imaging (MRI) and nerve conduction studies (NCS) in patients with ulnar neuropathy at elbow (UNE).Methods:In total, 46 who underwent MRI NCS a single center from 2014 to 2018 were included. Motor studies, including segmental inching tests, sensory performed. The 5-point severity score was evaluated based on signal ch...

It has been hypothesized that idiopathic carpal tunnel syndrome (CTS) is a manifestation of vitamin B6 deficiency. Some claim that B6 supplementation can alleviate symptoms. Others argue that pain relief occurs because of vitamin B6's anti-nociceptive properties or because B6 supplementation addresses an unrecognized peripheral neuropathy. Few studies on CTS and B6 employed electrodiagnostic te...

The radial nerve is the major nerve serving the extensor compartment of the arm. This article describes the anatomic features, clinical features based on lesion location, electrodiagnostic assessment, prognosis, and treatment of radial neuropathies. Numerous traumatic causes have been reported to result in radial neuropathies, including compression or stretch injury, surgical insult, or trauma....

The objective of this report was to develop a case definition of distal symmetric polyneuropathy to standardize and facilitate clinical research and epidemiologic studies. A formalized consensus process was employed to reach agreement after a systematic review and classification of evidence from the literature. The literature indicates that symptoms alone have relatively poor diagnostic accurac...

Basis of the Electroretinogram An electrical potential exists between the cornea and the fundus of the living eye. When the eye is illuminated by a flash of light a small potential is generated in addition to this corneofundal potential, which forms the ERG. This is analogous to the way in which the ECG is recorded above the steady skin potential. The final response is the sum of a number of co...
