Abstract
A resilient rod that provides adjustable directional resistance is disclosed. In one aspect of the invention, a resistance level may be determined based on a thickness of the rod and a position of an applied force with respect to a fulcrum point. In another aspect of the invention, at least one spine may be attached to the beam to increase a diameter of the beam along one axis. A resistance level may be determined based on a thickness of the rod, a position of an applied force and an orientation of the at least one spine with regard to the direction of the applied force. In other aspects of the invention, the resilient rods may be incorporated into various equipment that provide for adjustable resistance levels. In still other aspects of the invention, the resilient rod may be incorporated into medical devices that provide adjustable support for injured limbs or joints.
