title: Use of electromyography in the diagnosis of inflammatory myopathies.
abstract: Inflammatory myopathies are a heterogeneous group of myopathies in which there is biopsy-evident inflammation. In its evaluation it is essential to use neurophysiological techniques that provide information on the nature of the process. This paper reviews the electromigram pattern characteristic of inflammatory myopathies, its diagnostic value, limitations, and some clues on the interpretation of the results of neurophysiological techniques in the assessment of inflammatory myopathies.
