Electromyography (EMG) signal includes information of intended torque, angle and impedance parameters of the knee joint dynamics. In this paper, Generalized Regression Neural Network (GRNN) and Extreme Learning Machine (ELM) have been used in trying to estimate torque and corresponding angle about knee joint. Mean Frequency (MNF), Median Frequency (MDF), Mean Power (MNP), Total Power (TTP), Power...
This study aimed to identify the functional contribution of reflexes to human motor control during posture maintenance. Continuous random force disturbances were applied at the hand while the subjects were instructed to minimize the deviation resulting from the force disturbances. The results were analyzed in the frequency domain with frequency response functions (FRFs). Two FRFs were evaluated: 1)...
