Identification of quadriceps-shank dynamics using randomized interpulse interval stimulation
IEEE transactions on rehabilitation engineering
Absbuct-Model structures for artificially stimulated paralyzed muscle-limb system dynamics were developed and experimentally evaluated in paraplegic patients. The examined system consisted of the quadriceps, electrically stimulated using surface electrodes, and a freely swinging shank. The interpulse interval of the stimulation sequence was randomized to obtain persistent system excitation. The outputs of the system were the angular position, velocity, and acceleration, measured by externallydoi:10.1109/86.392369 fatcat:g5r3lwabkfecfauropffe2pgvi
