Simulation of Performance Enhancement of Bi-Lateral Lower-Limb Amputees Through Impulse Synchronisation with Self Selected Running Step Frequency

Current method of enhancing the performance of a bilateral amputee runners using energy return prosthesis is rarely linked to the system dynamics. In this paper a simple simulation is used to show that if a self selected running step frequency could be synchronized with dynamic elastic response of a...

description Current method of enhancing the performance of a bilateral amputee runners using energy return prosthesis is rarely linked to the system dynamics.
