Abstract: A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

Abstract: A truck bed cargo lift and loader is provided consisting of a pivotable and extendable platform or tray whose side supports are connected to linkage bars attached to carriers located in proximity to each base beam on the side of the lift and loader towards the open end of the truck bed, and which carriers travel along a worm gear jack screw with opposing threads installed in the cross member connecting the side base beams, such that when the jack screw rotates upon being driven by an electric motor or by a manually operated hand crank connected to a gearbox attached to the jack screw, the carriers travel towards and away from each other depending on the direction of rotation of the jack screw thereby raising and lowering the linkage bars with their platform or tray.
