The present invention provides a novel means of joint and body protection using engineered textiles to provide dynamic kinematic control within the device itself and for the underlying body part. The apparatus may be used in apparel or orthosis wherein a textile is organized about the proximal and distal aspects of a joint or body part and uses the mechanical and material characteristics of the engineered textile to dynamically control the kinetics of the body part and more specifically to prevent the body part from reaching extremes in range of motion. The engineered textiles can be designed to provide non-uniform increases in stiffness in any direction. The engineered textile may incorporate strain or strain rate dependant materials in which case stiffness properties would vary non-uniformly with velocity and / or acceleration within the device allowing for protection from blunt trauma, blast, or ballistic events anywhere on the body. A further aspect of the present invention is to provide a novel means of dynamically fitting and anchoring apparel, orthosis, body protection devices or other objects that need to be securely fixed to the body anatomy during joint flexion or extension, by using motion at a body joint to actuate a closure mechanism and bracing system that actively closes upon the body anatomy surrounding the joint and transfers loads created during dynamic restraint of the joint to anchor zones on the body.

An orthotic brace and brace hinge are disclosed where the brace hinge comprises a first hinge element operably connected to a second hinge element, at least one hinge element having a magnetic field whereby the magnetic field provides a magnetic force urging one hinge elements in a pre-determined direction. Embodiments of the present invention generally utilize magnetic forces to stabilize, influence and / or maintain adjacent joint portions in pre-determined desired relationships and for constraining motion and / or rotation of the joint portions. Through the use of the repelling and attracting forces of magnets, mechanical forces in the brace and brace hinge can be replaced or supplemented to reduce the force put on joint bones, to influence the bones so that the joint is biased into certain positions or to apply different forces through different points of joint flexion. Embodiments of braces with magnetic fields on other brace elements are also disclosed.

A prosthetic knee joint mechanism has an hydraulic load-activated knee-stabilizing device for resisting joint flexion.
