Emg test neuropathy

S Mello, O O'Toole, B McNamara
Older adults are at increased risk of both central and peripheral neurological disorders. Impaired nerve and muscle deficits contribute to morbidity and reduced quality of life. Our aim was to define the utilization and yield of nerve conduction studies (NCS) and electromyography (EMG) in older adults. We reviewed NCS and EMG records for all patients older than age 65 in the year 2012. Of 1,530 NCS and EMGs performed, 352 (23%) were in patients older than 65 (mean age 73.7, 52% male). 288 (83.7%) of NCS were abnormal as were 102 (71...

Here, we describe the clinical features of several members of the same family diagnosed with Friedreich ataxia (FRDA) and cerebral lesions, demyelinating neuropathy, and late-age onset without a significant cardiac involvement and presenting with similar symptoms, although genetic testing was negative for the GAA repeat expansion in one patient of the family. The GAA repeat expansion in the frataxin gene was shown in all of the family members except in a young female patient. MRI revealed arachnoid cysts in two patients; MRI was consistent with both cavum septum pellucidum-cavum vergae and nodular signal intensity increase in one patient...

BACKGROUND: Recent studies have reported that peripheral neuropathy (PN) is common in patients with Parkinson's disease (PD) and raised the possibility that levodopa neurotoxicity is the main culprit. METHODS: We evaluated the presence of large & small (autonomic) fiber PN in 54 consecutive patients with PD or parkinsonism in a tertiary outpatient clinic from Brazil. Initial PN screening consisted of history/neurological exam and skin wrinkling test (SWT). In addition, we also performed Nerve conduction studies/Electromyography (NCS/EMG) in all patients with PN signs/symptoms and/or abnormal SWT...

BACKGROUND: Median neuropathy at or distal to the wrist or carpal tunnel syndrome (CTS) is one of a number of muscle, tendon, and nerve-related disorders that affect people performing intensive work with their hands. Following a thorough history and physical examination, electrophysiological examination including both nerve conduction studies (NCS) and electromyography (EMG) testing may be performed and currently serve as the reference standard for the diagnosis of CTS. The EMG and NCS exams should identify the peripheral nerve, specific location in the nerve pathway, involvement of sensory and/or motor axons, and the presence of myelinopathy and/or axonopathy neuropathic process...

BACKGROUND: Conscious external anal sphincter contraction is mediated by the pudendal nerve. Pudendal neuropathy is, therefore, believed to result in fecal incontinence. Until urge sensation is experienced, fecal continence is maintained by unconscious external anal sphincter contraction, which is regulated by the anal-external sphincter continence reflex. The innervation of unconscious contraction is yet unknown. OBJECTIVE: We aimed to determine whether unconscious contraction is mediated by the pudendal nerve and whether age influences unconscious contraction...

OBJECTIVE: Electromyography (EMG) is used routinely to diagnose neuromuscular dysfunction in a wide range of peripheral neuropathies, myopathies, and neuromuscular degenerative diseases including motor neuron diseases such as amyotrophic lateral sclerosis (ALS). Definitive neurological diagnosis may also be indicated by the analysis of pathological neuromuscular innervation in motor-point biopsies. Our objective in this study was to preempt motor-point biopsy by combining live imaging with electrophysiological analysis of slow degeneration of neuromuscular junctions (NMJs) in vivo...
