Disclosed is a multi-axis corrective knee brace. The knee brace comprises a thigh cuff component (101) configured to engage rear thigh area of an user, a calf cuff component (102) configured to engage with the patient's leg at the calf area below the knee, and a pair of multi-axial hinge assemblies (103) coupling the thigh cuff component (101) and the calf cuff component (102) for relative articulation. The knee brace further comprises rotating hinge elements (90) connecting the pair of multi-axial hinge assemblies (103) to the a calf cuff component (102) and to the thigh cuff component (101). Specifically, the rotating hinge elements (90) are capable of adjusted towards inner and outer side by means of key in order to treat other deformities such as Bow Legs (Genu Varum deformity) and Knock Knee (Genu Valgum deformity).

An orthopedic device includes a hinge assembly, a frame having first and second frame components spaced apart from and connected to one another by the hinge assembly, a strap system extending between medial and lateral sides of the first frame component, and at least one tensioning element. The at least one tensioning element has a first end secured to the strap system and a second end coupled to the hinge assembly. Articulation of the hinge assembly pulls the strap system toward the frontal plane by the at least one tensioning element.

A support for an area of a body having a hinge joint includes: a flexible, elastically stretchable framework configured to extend across the hinge joint of the area of the body; and a hinge mechanism affixed to the framework. The hinge mechanism includes a strut component and a first arm component connected to the strut component such that the first arm component is rotatable relative to the strut component only about a first pivot axis. A second arm component is connected to the strut component such that the second arm component is rotatable relative to the strut component only about a second pivot axis. The strut component is configured to extend with the framework across the hinge joint such that the first pivot axis is located on a first side of the hinge joint and the second pivot axis is located on a second, opposite side of the hinge joint.

A versatile orthopedic device is arranged to convert between ligament and osteoarthritis treatment, and to accommodate a variety of leg anatomies. The orthopedic device is preferably configured as a double-upright brace indicating struts, frame component sections and associated hinges preferably intended to be along both medial and lateral sides of a wearer's leg. A strap kit with an unloading strap system may be added to the orthopedic device for conversion into an orthopedic device for osteoarthritis relief.

An apparatus is designed to provide support and correct form in order to perform rotator cuff strengthening exercises, either for rehabilitation or prevention of injury. In an exemplary embodiment, a cuff holds a person's elbow fixed at a position substantially perpendicular to curved plate secured to and parallel to a person's vertical (i.e., longitudinal) axis at the person's torso, which helps isolate internal and external rotation of the humerus and reduce any compensatory motions that can occur when the elbow is not supported. This optimally strengthens these important shoulder movements which in turn allows athletes to improve their upper extremity strength.

An orthopedic device has a rigid or semi-rigid frame element defining opposed first and second sides, and is adapted to extend about at least a portion of a limb. The device includes straps formed from a variety of segments having stretchable and substantially inelastic segments. The straps adjustably secure to the frame element, and stretch relative thereto. The device also includes a central strap pad arranged to connect two straps together such that a first strap of the two straps is movable relative to a second strap, and the first and second straps are maintained diagonal relative to one another.

A device for supporting at least one arm of a user includes one or more arm support elements each of which has an arm shell for placing the at least one arm of the user on the arm shell. Force is applied to the arm support elements by at least one passive actuator. A counter bearing for the applied force includes a force transmission element and a counter bearing element. A force application lever is engaged by the one passive actuator and is connected to the arm support or the force transmission element. The force application lever is torque proof and confines an angle which is adjustable.

A brace configured for attachment to a joint of a subject is provided. The brace includes a first arm having a first end and a second end. The brace includes a second arm having a first end and a second end. The brace includes a hinge assembly coupling the first end of the first arm with the first end of the second arm such that the first arm and the second arm are movable to different relative angular orientations. The brace includes a potentiometer coupled to the hinge assembly. A method of monitoring a relative angular orientation of a first arm of a brace relative to a second arm of the brace is also provided. The method includes monitoring an output of a potentiometer coupled to one of the first arm and the second arm.

A system for supporting a liner on a frame element includes a liner and a frame element. A fastener connects the liner to the frame element, such that the fastener corresponds to an aperture defined by the frame element. The fastener is configured and dimensioned to removably secure to the frame element at the at least one aperture. The frame element comprises a semi-rigid or rigid base frame element, and an interface layer secured about the base frame element. The interface layer is formed from a resilient material more compressible than the base frame element, and the liner is more flexible than the interface layer.

Artificial limbs and joints that behave like biological limbs and joints employ a synthetic actuator which consumes negligible power when exerting zero force, consumes negligible power when outputting force at constant length (isometric) and while performing dissipative, nonconservative work, is capable of independently engaging flexion and extension tendon-like, series springs, is capable of independently varying joint position and stiffness, and exploits series elasticity for mechanical power amplification.
