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.

A hip brace is provided which includes an iliac crest pressure plate, a femur pressure plate, a quadriceps pressure plate, and a bracket to connect the plates. The bracket includes one or more adjustable hinges to adjust positioning of at least one of the iliac crest pressure plate, the femur pressure plate, or the quadriceps pressure plate to correspond with dimensions of a user. The bracket further includes a range of motion restriction dial to control flexion or extension of the hip of the user, where the range of motion restriction is positioned on the bracket to correspond to the femur pressure plate.

Systems, methods, and apparatus provide artificial knees. Artificial knees include a thigh link configured to move in unison with a thigh of the person, a shank link configured to be rotatably coupled to the thigh link, and a compression spring rotatably coupled to the thigh link and coupled to a second end of shank link with a second end of the compression spring. During a first range of motion, the compression spring is configured to provide an extension torque between the thigh link and the shank link causing the artificial knee to resist flexion. After the first range of motion, the compression spring is configured to provide a flexion torque between the thigh link and the shank link encouraging the artificial knee to flex resulting in toe clearance during the swing phase. During the swing phase, the compression spring provides no torque between the thigh link and the shank link.

A knee brace comprising a frame assembly comprising an outer frame portion and an inner frame portion. The outer frame portion has a first outer transverse member, a second outer transverse member, and an outer side member configured to extend along a length of a first side of a user's leg when worn by the user, the outer side member extending between the first outer transverse member and the second outer transverse member. The inner frame portion has a first inner transverse member, a second inner transverse member, and an inner side member opposite the outer side member and is configured to extend along a length of a second side of a user's leg when worn by the user, the second side member extending between the first inner transverse member and the second inner transverse member. The outer frame portion and inner frame portion define a top portion of the frame assembly and a bottom portion of the frame assembly, the top and bottom portions configured to be pivotable relative to each other. The frame assembly additionally comprises a flex member connecting the inner frame portion and the outer frame portion in at least one of the top and bottom portions of the frame assembly. In embodiments, a securement system may be included to form a knee brace assembly or system.

The present invention describes a multi-positional, modular bodily limb splinting system consisting of at least one pair of rigid, shared geometry interlocking male and female splint members which allow for expedient placement and treatment of a limb injury. The male splint member includes a locking post and an adjustable locking post at one end, and the female splint member includes a locking aperture operable to receive and interlock with the locking post and a plurality of adjustable apertures operable to receive and interlock with the adjustable locking post. The male and female splint members of various lengths may be positioned into one or more of several incremental angled configurations of up to 360° to conform to the extremity injury.

The present invention relates to a patella protection system (1) comprising an upper member (21) designed to be positioned in proximity of an upper part of the wearer's leg, a lower member (22) designed to be positioned in proximity of a lower part of the wearer's leg and an intermediate guard member (23) designed to be positioned over the patella and operatively connected to the upper member (21) and the lower member (22). The upper member (21) and the lower member (22) are designed to move within the intermediate guard member (23) between a straight configuration and an angulated configuration. The invention also relates to a knee brace (2) comprising such a patella protection system (1).

A motion assistance apparatus including a proximal frame configured to support a proximal part of a user, a distal frame configured to support a distal part of the user, and a force transmitting member slidably connected to the proximal frame, and rotatably connected to the distal frame is provided.

A joint device of an orthosis with an upper part and with a lower part that is arranged on the upper part in an articulated manner, with a first fastening device for securing the upper part to a patient and a second fastening device for securing the lower part to a limb, wherein the joint device connects the upper part to the lower part in an articulated manner and has an upper part binding and a lower part binding via which the upper part and the lower part can be secured to the fastening devices, wherein the joint device has at least four degrees of freedom.

A finger brace device is disclosed herein. The finger brace device can comprise a first hinge component configured to connect a proximal component configured to fit around at least a first portion of a finger near a wrist, to an intermediate component located at a central portion of the apparatus, wherein the proximal component is located at a lateral portion of the apparatus. Also disclosed is a second hinge component configured to connect the intermediate component of the apparatus to a distal component. Furthermore, a ball and socket joint is configured to allow a broad range of motion between the proximal component of the apparatus and the plate component.

A joint for a rehabilitation device and a rehabilitation device are disclosed. The joint is defined for operation between an end of a first member and an end of a second member. The joint enables the second member to pivot at the joint with respect to the first member. The joint includes a positioning mechanism for defining a set position from which the second member pivots. The joint also includes a restriction mechanism for restricting the degree of pivoting of the second member, from the set position. The joint further includes a biasing mechanism for biasing the second member such that it returns to the set position when an opposing force applied to the second member is less than the bias of the biasing mechanism. When the joint is in the set position, the biasing mechanism is configured such that no bias is applied to the second member.
