1. A method for neurally controlling a device, comprising the steps of: a) mechanically linking at least one pair of agonist and antagonist muscles of an individual, wherein a nerve innervates each muscle, and each of the agonist and antagonist muscles of the at least one pair of muscles includes an end linked to an end of the other muscle of each pair, and wherein each pair of linked muscles includes two opposite ends; b) supporting each of the at least one pair of agonist and antagonist muscles at the opposite ends at a support, whereby contraction of the agonist muscle of each pair will cause extension of the paired antagonist muscle; c) implanting at least one electrode in each muscle of each pair to thereby form at least one associated pair of electrodes; and d) electrically connecting the at least one electrode to a motor controller of the device; whereby activating the agonist or antagonist muscle of the at least one pair of the agonist and antagonist muscles with the nerve innervating the corresponding muscle provides a signal to the motor controller, thereby neurally controlling the device.
