A knee orthosis is provided. In described embodiments, the knee orthosis is designed to follow a natural movement of a wearer's knee along an asymmetric helicoidal axis of rotation. In some embodiments, the knee orthosis has hinges with shells having displacing geometric centers which do not coincide. In some embodiment, the knee orthosis is made of femoral and tibial hinges manufactured as single integral pieces. In some embodiments, the orthosis is configured to realign the wearer's knee in a frontal plane. Corresponding methods for designing and manufacturing a custom knee orthosis are also provided.

A knee brace comprises a medial hinge device and a lateral hinge device each including an upper arm configured to be attached to a thigh, and a lower arm configured to be attached to a shank. An assembly joins free ends of the upper arm and of the lower arm in each of the medial hinge device and the lateral hinge device, the assembly of each of the medial hinge device and the lateral hinge device including an operative set of pivot and pivot slot, and another operative set of follower and at least one follower slot. The assemblies of the medial hinge device and a lateral hinge are configured to induce a corrective constraint on leg movement. A system for generating a knee brace customized to a patient is also provided.

Systems and methods for assistive devices for replacing or augmenting the limb of an individual, such devices comprising a joint and a powered system; the powered system having a first configuration in which the powered system rotates the joint by applying power to the joint, and a second configuration that allows for rotation of the joint without actuation of the powered system.

A connector for a strap includes a buckle assembly having a base part, and a strap mount flexibly depending from the buckle assembly. The strap mount is integrally connected to the base part such that the base part is rigid when the strap mount bends relative thereto.

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.

An orthopedic device comprising a first shell, a second shell, and a hinge connecting to the first and second shells. A first strap having a first end slidably connects to the first shell and a second end removably anchors to the second shell. An overlay extends over a portion of the first shell and forms a clearance with the first shell into which the first end of the first strap extends. Portions of the overlay secure to the first shell outside of the clearance.

A connector for a strap includes a buckle assembly having a base part, and a strap mount flexibly depending from the buckle assembly. The strap mount is integrally connected to the base part such that the base part is rigid when the strap mount bends relative thereto.

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.

Provided are a connecting module and a motion assistance apparatus including the same, the connecting module including a case provided to incline downward from a space recessed between a waist and a hip of a user to a hip joint of the user, a power transmitting assembly disposed in an internal portion of the case, and a supporting module connecting portion disposed at an output terminal of the power transmitting assembly and to be fastened with a supporting module that supports a leg of the user.

A guide joint (1) and a joint orthosis (2) provided with the guide joint for supporting and guiding an anatomical joint (7). The guide joint (1) has a first joint member (3) and a second joint member (4), and the joint members (3, 4) are connected to one another by a first linear guide (5) and a second linear guide (6). Each of the linear guides (5,6) has a guide track (10, 11) formed in the second joint member (4) as a slot or groove, in which in each case a sliding element (12, 13) arranged in the first joint member (3) engages, wherein the guide tracks (10, 11) intersect. The two sliding elements (12, 13) are spatially separate and spaced apart and protrude from a lateral surface of the first joint member (3).
