A frame configured of a plurality of links pivotally connected to one another is flexibly bent, and pins that connect the plurality of links that constitute the frame are inserted into and slide in a curve-shaped slot and a slot in a vertical direction so that, even though the frame is bent, the entire length of the frame is increased and ends of the frame can be moved along a straight line that is horizontal with respect to the ground.

Systems, methods, and apparatus provide an artificial knee. Such artificial knees may 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 at a first end and coupled to the shank link at a second end. The compression spring is configured to provide an extension torque between the thigh link and the shank link during a first range of motion of the thigh link and the shank link relative to each other. The compression spring is configured to provide a flexion torque between the thigh link and the shank link during a second range of motion of the thigh link and the shank link relative to each other.

A joint assembly may include a first rolling cam that includes a first cam portion, and a first extension extending from the first cam portion, and a second rolling cam that includes a second cam portion to be in contact with the first cam portion, and a second extension extending from the second cam portion.

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.

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 wearing module and a motion assistance apparatus including the same is disclosed, wherein the wearing module may include a base frame having a predetermined curved form to cover a body portion of a user, the base frame formed by a rigid material, a middle frame connected to the base frame and formed by a flexible material, the middle frame disposed in a longitudinal direction perpendicular to the base frame, and a connecting member extended from both end portions of the base frame to cover an edge of the middle frame, and bent to correspond to a deformation of the middle frame.

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 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.

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.

A joint assembly including a plurality of frames, each including contactors provided in opposite directions to each other and a middle portion configured to connect the contactors, and a connecting member configured to maintain a state in which contactors of two neighboring frames among the plurality of frames are in contact with each other is disclosed.
