A brace, comprising: (i) a palmar piece configured to conform to the palmar side of a user's wrist, comprising an opening sized for the user's thumb, the palmer piece further comprising a first pin extending outwardly from an outer surface of the palmar piece in a first direction, further comprising a second pin extending outwardly from the outer surface in a first direction, wherein the first and second direction are opposite one another; and (ii) a forearm piece configured to conform to the user's forearm, comprising a first pin opening sized to receive the first pin, further comprising an elongated slot configured to receive the second pin in a sliding relationship; wherein the palmar piece is moveable relative to the forearm piece such that the user can move the wrist along the user's dart thrower's plane.

A knee brace assembly with a proximal compression system adapted to be secured to the thigh and a distal compression system adapted to be secured to the calf. The brace includes lateral and distal hinge assemblies connecting the proximal compression system and the distal compression system to permit rotational movement of the proximal compression system with respect to the distal compression system. At least one inelastic strap extends around the proximal compression system and the distal compression system. The strap is leveraged to tighten the proximal compression system and the distal compression system to compress soft tissue in the thigh and calf when the leg is extended, but to release the proximal compression system and the distal compression system when the leg is in flexion.

A hinged ankle brace including a foot pad member and an ankle cuff which are hingedly secured together by flexible joint members. The flexible joint members yieldably resist hinged movement between the foot pad member and the ankle cuff.

The present disclosure describes transmission systems for use in artificial joints of assistive devices, such as assistive prostheses, orthoses, and powered exoskeletons. A variable transmission is configured to automatically or manually adapt the torque profile to the demand of different locomotion tasks, such as a relatively high torque and low speed profile for a task such as standing up or ascending stairs, or a relatively low torque and high speed profile for a task such as walking.

A knee brace includes an upper frame portion, a lower frame portion, a hinge pivotally coupling the upper frame portion and the lower frame portion, and a knee cup. The knee cup includes an outer cup and an inner cup. The outer cup has a first portion coupled to the upper frame portion and a second portion coupled to the lower frame portion. The inner cup has an outer surface and an inner surface. The inner surface is positioned to engage a patella of a wearer of the knee brace.

An articulated joint for orthopedic orthoses or braces, where the brace comprises rods for the tibia (51) and rods for the femur (52) and an articulated hinge (53) provided with four pivots designed to ensure the necessary mobility obtained by the presence of multiple centres of rotation, and where the articulated hinge (53) comprises two plates (55, 56) reciprocally connected by means of four quadrilaterally positioned hinging means such as rivets (57) or similar, in order to enclose the ends of the rods (51, 52) which face each other, wherein between the ends of the two rods (51, 52) there are spacers or stops (63), and where the outer plate (55) of the articulated hinge (53) presents openings (61, 62) in which are inserted pairs of stops (63) which limit the ROM of the joint.

A device and method for using the device arranged to maintain anatomical alignment between a joint by creating a dynamic load around the joint to restore and maintain the anatomical alignment. The orthotic device uses a hinge to create a directed force on a tibia by maintaining misalignment of an instant center of rotation (ICoR) of the hinge at a position relative to an anatomical knee joint.

A knee brace which allows the same bolster pad to be used for either the right or left leg, is adjustable to compensate for the differing angle between men and women and allows individual adjustment for each patient's comfort and brace rotation for proper fit and joint alignment. These characteristics are obtained by a contoured bolster that is selectively mountable at various positions on either side of the shin cross piece depending on whether the brace is for the left or right leg, the bolster always being on the medial side of the shin to contact the flat section on the front of the shin thereby minimizing unwanted rotation of the brace. The bolster pad has a front face with a curvature matched to a curvature of an inner side of the cross piece and a flat on a rear side to contact the front of the shin.

A polycentric hinge for a knee brace, and knee brace including such hinge. The hinge includes first couple of hinge arms, second couple of hinge arms, and hinge body for hinging together the first couple of hinge arms and second couple of hinge arms. Each hinge arm of the first couple and each hinge arm of the second couple has a first end pivotally enclosed inside said hinge body and a second end pivotally fixed to a mounting frame. The hinge body is provided with pivoting means adapted to engage said first ends to define four different and spaced apart rotation axes extending transversally with respect to a longitudinal axis of the hinge body. The first ends of each hinge arm of the second couple can be connected to each other, so that rotation of the mounting frame causes rotation of both hinge arms around their respective rotation axes.
