“…In threshold control, if the EMG signal level is higher than a particular value, the command will be generated to close the fingers; otherwise, the hand will be in an open state. This control scheme provides either fully open or fully close operation of the hand with fixed prehension force, making the control quite unnatural (Asghari Oskoei and Hu 2007;Herle et al 2012). On the other side, the proportional scheme provides the flexion of fingers as per the intensity of the captured EMG signal.…”

“…Proportional control is a non-pattern recognition-based control scheme that provides natural control and faster-grasping capability to the hand (Fougner et al 2012;Lenzi et al 2011). Such a control scheme relies on factors like characteristics of EMG detection unit, position of electrode on the skin and muscle fatigue for proper generation of control commands (Herle et al 2012;Hudgins et al 1993).…”

“…Para próteses de membros superiores, os pesquisadores optam pela abordagem de controle a partir de sinais mioelétricos -eletromiografia (EMG), feito utilizando-se leitura de pulsos elétricos musculares, por se tratar de um método não invasivo e de fácil adaptação [5,6].…”

“…Por otro lado, debido a que las señales EMG son muy susceptibles de corrupción por efecto de campos electromagnéticos cercanos, e incluso por cambios fisiológicos del paciente, la mejora de la precisión de los algoritmos para detectar la intención de movimiento también ha sido un tema de investigación de interés hasta la fecha. En este campo, los aportes en el control de prótesis avanzadas se pueden clasificar en tres grandes grupos: 1) aportes en cuanto al hardware de adquisición y procesamiento de señales [3], 2) aportes en cuanto a combinaciones de características extraídas de las señales EMG que proporcionen vectores de características que sean discriminantes [8], [9], y 3) aportes acerca de los métodos de clasificación desde múltiples enfoques, como: redes neuronales artificiales (RNN) [10], [11], lógica difusa (FL) [12], análisis discriminante lineal (LDA) [13], máquinas de soporte vectorial (SVM) [14], k vecinos próximos (k-NN) [15].…”
