Abstract
The surface electromyography (sEMG) analysis can provide information on muscle
fatigue status by estimation of muscle fibre conduction velocity (MFCV), a measure of the
travelling speed of motor unit action potentials in muscle tissue. This paper proposes a technique
for MFCV estimation using cross-correlation methods and variable bitstream modulation. The
technique displays an estimate based on a set of data generated by the gain variation modulation,
providing an average estimate of the MFCV. The observed trend of MFCV decrease correlates
with the fatigue state of the observed muscle. Finally, the values found were compared with
information from the literature, validating the method and showing the advantages of using
variable modulation.
Resumo: A an´alise da eletromiografia de superf´ıcie (EMGs) pode fornecer informa¸c˜oes sobre
o estado de fadiga muscular pela estima¸c˜ao da velocidade de condu¸c˜ao de fibras musculares
(VCFM), sendo uma medida da velocidade de deslocamento dos potenciais de a¸c˜ao no tecido
muscular. O presente artigo prop˜oe uma t´ecnica para estimativa da VCFM utilizando m´etodos
de correla¸c˜ao cruzada e modula¸c˜ao vari´avel de fluxo de bits. A t´ecnica exibe uma estimativa
baseada em um conjunto de dados gerados pela varia¸c˜ao do ganho de modula¸c˜ao, fornecendo uma
estimativa m´edia da VCFM. A estimativa representa uma diminui¸c˜ao da VCFM correlacionada
com o estado de fadiga do m´usculo observado. Por fim, os valores encontrados foram comparados
com informa¸c˜oes da literatura, validando o m´etodo e mostrando as vantagens do uso da
modula¸c˜ao vari´avel.
