ABSTRACT
Since their inception, conventional electrodiagnostic techniques have played a critical role in the diagnosis and investigation of motor neuron disease. However, despite years of emphasis on electrodiagnosis in neurology training programs, patients continue to be misdiagnosed with amyotrophic lateral sclerosis (ALS) because of poorly performed and improperly interpreted electrodiagnostic studies. Consequently, an understanding of the proper role of electromyography and nerve conductions is essential for the clinical diagnosis of ALS.
