A device for supporting the arms of a user, has support elements for the user's arms, a counter bearing element, and a force transmission element connectable to the counter bearing element. The force transmission element and the arm supports are connected to each other by a joint and are moveable relative to each other about a swivel axis. A force application lever is connected to the joint and extends away from the joint. A passive actuator is connected at one end to the force transmission element and at another end to a point of application on the force application lever. The point of application is moveable on the force application closer to or further from the swivel axis of the joint.

The invention relates to a hard frame (100) for a joint-bridging extremity joint orthosis, containing two mutually opposed longitudinally extending joint splints (110, 120), the proximal joint arms (113, 123) thereof being connected to one another via a transverse proximal bridge arch (310) and forming a proximal extremity holder (300), and the distal joint arms (112, 122) of which being connected to one another via a transverse distal bridge arch (210) and forming a distal extremity holder (200). According to the invention, at least one of the bridge arches (210) is mounted on joint arm ends (114, 124) of the associated joint arms (112, 122) of the joint splints (110, 120) connecting the bridge arch (210), noreover is mounted pivotably about at least one pivot axis (222) at a joint (220).

A compact, multi-Degree of Freedom (DoF) support structure located within a single biomechanical plane, for supporting an orthotic device allowing for a user's full range of motion in all biomechanical plans, The support structure comprises a support belt configured to be secured around the user's body and a multi-DoF motion element that includes a frontal plane rotational DoF mechanism, a transverse plane rotational DoF mechanism and a sagittal plane rotational DoF mechanism, allowing the multi-Degree of Freedom (DoF) support structure to support the orthotic device while allowing for the user's full range of motion in all biomechanical plans.

A customizable knee brace for use in the treatment of osteoarthritis is provided. The customizable knee brace includes a lateral upright. The lateral upright includes at least a first semi-rigid support, a second semi-rigid support, and a hinge physically coupling the first semi-rigid support and the second semi-rigid support. The customizable knee brace further includes a thigh cuff constructed of formable material and coupled to the first semi-rigid support. The customizable knee brace further includes a shin cuff constructed of formable material and coupled to the second semi-rigid support. The customizable knee brace further includes an elastomeric web framework coupled to the lateral upright and configured to secure an area of a knee of a patient when wearing the customizable knee brace. The customizable knee brace further includes at least one tensioning element configured to adjust a tension of the elastomeric web framework.
