Specialized Electrodiagnostic Studies
2018In addition to nerve conduction nerve studies and needle EMG, the clinical EMG study include more specialized examinations Some of the tests, such as the F waves and H reflexes are now often used as part of the routine nerve conduction studies. Others are utilized for specific indications: Repetitive nerve stimulation and single fiber EMG are used ...

ALEXANDER DISEASE: CLINICAL, ELECTRODIAGNOSTIC AND RADIOGRAPHIC STUDIES
Neuropediatrics, 1981A 10-month-old boy with Alexander disease is described. He was clinically characterized by early onset of megalencephaly, psychomotor retardation, spasticity and recurrent seizure attacks. Pathological examination of the biopsied cerebrum revealed a large number of Rosenthal fibers in the white matter and beneath the pia in association with advanced ...

Electrodiagnostic studies in myasthenia gravis.
Changgeng yi xue za zhi, 1993Forty-three patients with myasthenia gravis (MG) were studied to compare the sensitivity of repetitive nerve stimulation (RNS) test with single fiber electromyography (SFEMG) in the diagnosis of MG. SFEMG was abnormal in 81% (35 of 43 cases), while RNS test was abnormal in 53% (23 of 43 cases). In ocular MG, SFEMG showed a much higher positive rate (70%
