Resumos

Neste estudo os autores se propõem a estabelecer os pontos mais adequados para o registro do potencial de ação muscular composto dos músculos frontal, orbicular do olho e músculos do sulco nasolabial, após estimulação do nervo facial. Também, o melhor posicionamento do eletrodo estimulador e a variação entre as amplitudes do primeiro e último potencial de ação muscular composto dos músculos do sulco nasolabial, após 20 estímulos supramáximos sucessivos.

In this study it is, intended to establish the more appropriate points to register the compound action potential from m. frontalis, m. orbicularis oculi and nasolabial fold muscles. The optimum site for stimulating electrodes and differences between the first and the last compound action potentials after 20 consecutive stimuli delivered at 1 Hz were analysed.

The optimum site for stimulating electrodes and differences between the first and the last compound action potentials after 20 consecutive stimuli delivered at 1 Hz were analysed.
