Abstract

Método y sistema de determinación de la duración de los potenciales de acción de unidad motora en señales electromiográficas intramusculares.#La invención comprende superponer el tren de potenciales de acción de la unidad motora capturado y recorrerlo mediante una ventana deslizante, donde en cada salto: se calcula un coeficiente de similitud por cada pareja del tren de potenciales, se obtiene un estadístico a partir de los coeficientes calculados para todas las parejas y, si se cumple una condición de finalización, se obtiene una curva de similitud, se determina el instante temporal donde la curva alcanza el valor máximo, el instante temporal inicial (T{sub,inic}) donde la curva atraviesa un primer umbral de inicio y el instante temporal final (T{sub,fin}) donde la curva atraviesa un primer umbral de fin y se obtiene la duración del potencial de los potenciales de acción de unidad motora mediante la diferencia entre T{sub,fin} y T{sub,inic}.Method and system for determining the duration of motor unit action potentials in intramuscular electromyographic signals. # The invention comprises superimposing the train of action potentials of the captured motor unit and traversing it through a sliding window, where at each jump: calculates a coefficient of similarity for each pair of the potential train, a statistic is obtained from the coefficients calculated for all couples and, if a termination condition is met, a similarity curve is obtained, the time point is determined where the curve reaches the maximum value, the initial temporary instant (T {sub, start}) where the curve crosses a first start threshold and the final temporary instant (T {sub, end}) where the curve crosses a first end threshold and the potential duration of the motor unit action potentials is obtained by the difference between T {sub, end} and T {sub, start}.
