1. An adjustable resistance joint brace comprising:

  • a first strut having a top surface, a bottom surface, and an aperture extending through the top surface and the bottom surface;

    a second strut having a top surface, a bottom surface, and an aperture extending through the top surface and the bottom surface;

    a central adjustable resistance pivot assembly joining an end of the first strut with an end of the second strut, the central adjustable resistance pivot assembly comprising;

    a center washer positioned between the bottom surface of the first strut and the top surface of the second strut, wherein an opening in the center washer is aligned with the aperture of the first strut and the aperture of the second strut;

    a clamp comprising a first disc and a second disc for securing the first strut and the second strut to the center washer, each disc having a hole therein that is aligned with the hole of the other disc, the apertures of the first and second struts, and the opening in the center washer;

    wherein the first disc of the clamp is positioned above the top surface of the first strut, and the second disc of the clamp is positioned below the bottom surface of the second strut;

    a mounting nut positioned below the second disc of the clamp and extending through the hole in the second disc of the clamp, the aperture of the second strut, and the center washer;

    a threaded control knob positioned on a top surface of the first disc of the clamp and extending through the central adjustable resistance pivot assembly for insertion into the mounting nut;

    wherein the threaded control knob interconnects with the top surface of the first disc of the clamp to control, upon rotation, compression of the first strut, the second strut, and the center washer, thereby controlling a resistance level during flexion and extension of the first strut and the second strut;

    a sleeve for positioning the brace; and

    pockets positioned on the sleeve for receipt of a portion of the struts extending away from the central adjustable resistance pivot assembly;

    wherein the clamp comprises a flexible arch connecting the first disc with the second disc, such that the flexible arch is formed to bend inward when acted upon by the threaded control knob.
