Os autores apresentam uma revisão histórica destacando o papel do Professor Derek Denny-Brown e do doutor Joseph Buford Pennybacker no desenvolvimento da eletromiografia atual, ao longo dos oitenta anos de seu artigo original em 1938, sobre potenciais de fasciculação e fibrilação, e os estudos subsequentes que descreveram a maioria das mudanças elétricas necessárias para realizar e interpretar EMG.
