Needle Electromyography and Histopathologic Correlation in Myopathies
Dr. Behzad Elahi interviews Dr. Devin I. Rubin on his article, Needle Electromyography and Histopathologic Correlation in Myopathies. Fibrillation potentials and short-duration MUPs predict pathologic changes of muscle fiber necrosis, splitting, and/or vacuolar changes (as seen with inflammatory myopathies and muscular dystrophies). Absence of fibrillation potentials suggests other myopathologic changes (e.g., congenital myopathy). Muscle Nerve 59:315-320, 2019.
