Customized hinge for controlling extension and flexion motion of an orthosis during use

An orthosis, comprising:

• a sleeve;
• a first strut member integrated at least partially within the sleeve;
• a second strut member integrated at least partially within the sleeve;
• and
• a central unit pivotally coupled to the first strut member and the second strut member, the central unit including
• a hinge front plate,
• a first hinge cover rotationally coupled to the hinge front plate, the first hinge cover includes a first base component and a first arm component extending from the first base component, and
• a second hinge cover rotationally coupled to the hinge front plate, the second hinge cover includes a second base component and a second arm component extending from the second base component,
• wherein concurrent rotational movement of the first hinge cover and the second hinge cover in a first rotational direction places the central unit into a locked state and concurrent rotational movement of the first hinge cover and the second hinge cover in a second rotational direction places the central unit into an unlocked state.

A hinge comprising:

• a plurality of geared struts including a first geared strut and a second geared strut;
• and
• a central unit including
• first hinge cover including a first base component and a first arm component extending from the first base component, wherein the first hinge cover is configured to rotate in a first rotational direction and a second rotational direction opposite to the first rotational direction;
• a second hinge cover including a second base component and a second arm component extending from the second base component, wherein the second hinge cover is configured to rotate, independent of the first hinge cover, in the first rotational direction and the second rotational direction, and
• one or more stop components removably positioned within the central unit to restrict movement of the second geared strut,
• wherein concurrent rotational movement of the first hinge cover and the second hinge cover in the first rotational direction places the central unit into a locked state to secure positioning of the one or more stop components and concurrent rotational movement of the first hinge cover and the second hinge cover in the second rotational direction places the central unit into an unlocked state to allow for removal of the one or more stop components from the central unit.
