RESUMO

RESUMO Eletromiografia quantitativa é uma ferramenta importante para a avaliação de miopatias, e alguns pacientes asmáticos de difícil controle podem ter um processo miopático subclínico, mesmo usando apenas corticosteroides inalatórios, de acordo com alguns artigos. Nesse artigo a eletromiografia quantitativa do diafragma foi usada para avaliar os pacientes asmáticos de difícil controle, comparando com um grupo controle. Diferenças significativas nas amplitudes, durações e índices de tamanho dos potenciais de unidades motoras foram encontradas, com parâmetros mais baixos nos pacientes asmáticos, o que pode indicar um processo miopático.ABSTRACT Quantitative electromyography is an important tool to evaluate myopathies, and some difficult-to-treat asthmatic patients may have a subclinical corticosteroid myopathic process, using only inhaled corticosteroid, according to some studies. In this report, diaphragm quantitative electromyography was used to evaluate asthmatic difficult-to-treat patients, comparing them with a control group. Significant differences were obtained in amplitude, duration and size index of motor unit action potentials, with lower parameters in the asthmatic patients, which may indicate a myopathic process.
