Mathematical modelling of natural limb motion and actuation can greatly facilitate understanding of the biomechanics and control of a human limb, and can be used in the design of controllers for multi-axis prosthetic arms or the design of functional neuro-stimulators (FNS) for paralyzed limbs. The motion of a human limb involves the simultaneous control of each muscle of the limb. This simultaneous control provides stability, linkage stiffness, and force balance of the entire limb system, if not the entire body, in addition to the primary action of the limb. This idea of synergy of the entire system suggests that a prosthetic limb or a neuro-stimulated paralyzed limb should not be considered as an autonomous system but rather as an integral, dynamically coupled part of the person. Such a control scheme should free functionally sound parts of the body from controlling or actuating prosthetic or stimulated limbs, thus minimizing the conscience effort on the part of the person.
