Abstract: The present invention relates a system that can configure a stimulus for functional electrical stimulation (“FES”) to maintain a constant muscle force while delaying the onset of muscle fatigue and a related method of use. The stimulus can be delivered to a nerve via a set of multiple electrode contacts according to a stimulation parameter that maximizes a joint moment associated with the stimulus and minimizes the overlap between pairs of contacts. The joint moment can be related to the muscle force, and the overlap can be related to the onset of muscle fatigue.

Abstract: An implantable cuff includes an elastic collar, at least one conductive segment disposed on or within the elastic collar, and at least one conductor in electrical communication with the at least one conductive segment. The elastic collar defines an internal opening configured to receive an internal body tissue. At least a portion of the elastic collar includes a stiffening region having a stiffness greater than a second region of the elastic collar. The at least one conductor is configured to operably mate with an apparatus capable of delivering electrical stimulation to, and/or recording an electrical activity of, the internal body tissue.

Abstract: Systems and methods are provided for stimulating motor units. An electrode array includes a plurality of electrodes configured to provide stimulation to respective motor units of a plurality of independent, mutually agonist motor units. A stimulator assembly is configured to provide a stimulation current to each electrode of the plurality of electrodes. The stimulation current is provided such that a sum of respective time-varying moments at the plurality of motor units remains substantially constant and non-zero.

Abstract: An orthotic brace (30) for a joint includes a bracing device (40) having first and second portions (42, 44) movable relative to one another and a mechanism (100) for placing the bracing device (40) in a first condition in which the first portion (42) has a first resistance to movement relative to the second portion (44) and a second condition in which the first portion (42) has a second, different resistance to movement relative to the second portion (44). The mechanism (100) is capable of placing the bracing device (40) in a third condition in which the first portion (42) has a third resistance to movement relative to the second portion (44) that is between the first and second resistance.
