Motor unit conduction velocity distribution estimation: Assessment of two short-term processing methods

Abstract: Muscle fibre conduction velocity (MFCV) can be used as an index of the structural and/or functional modifications that can occur during fatigue or pathological processes. Current evaluation of MFCV from surface electromyography (SEMG) classically produces an average value. However, a single mean value is not sufficient when modifications affect only a small part of the conduction velocity distribution. In such a case, an estimation of the whole motor unit conduction velocity distribution (MUCV) would be advant… Show more

“…The detection of peaks or valleys has been applied in many studies on single MU CV (LYNN, 1979;GYDIKOV, 1981;HOGREL and DUCHENE, 2002). it is clear that the temporal resolution with which a peak is detected is limited by the sampling rate, which should thus be sufficiently high (or the signals should be re-sampled off-line).…”

“…A abordagem da estimativa por meio da média nem sempre é suficiente para expressar adequadamente os fenômenos fisiológicos, considerando que ela é influenciada por uma variedade de fatores incontroláveis (Farina et al, 2001). Outra alternativa é estimar a distribuição da VC ao longo do tempo que permite caracterizar os componentes individuais de propagação da VC (Hogrel & Duchene, 2002;Ledoux et al, 2006 …”

“…Ele é um parâmetro complexo para ser estimado com precisão, pois a sua estimativa é afetada pela contribuição de todos os potenciais de ação superficiais ativos. Isto se dá devido aos seguintes fatores: tipo e diâmetro das fibras musculares, concentrações de íons, pH, temperatura do músculo e a taxa de disparos das unidades motoras (Farina & Merletti, 2000;Farina et al, 2000b;Hogrel & Duchene, 2002).…”
