In clinical electromyography (EMG) musculus extensor digitorum brevis (MEDB) is known as "the marker" for L5/sl radiculopathy. Radiculopathy is mainly sensory syndrome in which the pain appears in innervation's zone of one or more spinal nerves. Moreover, in clinical practice it is also known that radiculopathy is not only sensory disorders but also may be followed by muscle weakness and atroph...

Neuromyelitis optica spectrum disorders (NMOSD) is a demyelinating syndrome of the central nervous system. This case report describes a 31-year-old woman whose electromyography revealed radiculopathy in the left L5-S1 spinal segment without anatomical abnormalities on lumbosacral magnetic resonance imaging (MRI). She was diagnosed with NMOSD based on gadolinium contrast whole spine and brain MR...

conclusions results show that trigger point injection therapy in patients suffering from chronic lumbosacral radiculopathy with trigger points can significantly improve their recovery, and conservative therapy may not be adequate. results out of 98 patients, 64 had trigger points. thirty-two patients were assigned to each group. pain scores (mean ± sd) in tp group was 7.12 ± 1.13 and in n group...

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...

Compression or irritation of the sciatic nerve and its branches, the common fibular and tibial nerves, causes sciatica which is a common syndrome characterized most often by radiating pain from the lower back down the legs and also manifesting as sensory and motor deficits. Sciatica is a common presentation of lumbosacral disc prolapse and degenerative disease of the lumbar spine in ambulatory ...

OBJECTIVE The purpose is to describe active and passive physical maneuvers that provoke or alleviate lumbosacral radiculopathy and/or sciatica to demonstrate how these maneuvers function in common orthopedic and neurological tests/signs. METHODS Descriptions of the maneuvers and their countermaneuvers are provided to establish an understanding of their mechanisms and influence on lumbosacral ...

PURPOSE To evaluate the clinical significance of continuous intradural lumbosacral nerve root enhancement in symptomatic patients without prior lumbar surgery. METHODS Fifty-three patients without prior back surgery, referred to our institution for evaluation of low-back pain and radiculopathy, were studied with gadolinium-enhanced MR (0.1 mmol/kg) of the lumbar spine. Scans were reviewed for...

STUDY DESIGN Prospective cohort study. PURPOSE This study was to investigate interside asymmetries of three lower extremity somatosensory evoked potentials (SSEPs) in anesthetized patients with unilateral lumbosacral radiculopathy. OVERVIEW OF LITERATURE Although interside asymmetry is an established criterion of abnormal SSEP, little is known which of the lower SSEPs is more sensitive in d...
