The invention relates to a pivoting-limitable biaxial joint, especially for a joint orthosis for supporting and variably limiting the joint flexion. The invention provides an improvement of known joint orthoses. A limiting wedge (300) can be inserted into the joint housing (200) in the axial direction.

The present disclosure relates to a device including electrostatic brakes providing haptic kinaesthetic feedback to a user in e.g. assistive, rehabilitation or virtual reality scenarios, as well as tele-manipulation.

A prosthesis or orthosis for a joint, such as an ankle, which includes a first body, a second body, and an articulated joint between the first and second bodies, the articulated joint allowing the rotation of the first and second bodies with respect to one another around a joint rotation axis. It further includes a locking mechanism configured to selectively lock the rotation between the first and second bodies in one direction, when it is in a locked configuration, and a transmission mechanism such that a rotation of the joint rotation axis generates a movement of a lockable part of the locking mechanism. The axis of the movement of the lockable part is shifted relative to the joint rotation axis and the transmission mechanism includes a reducer configured to reduce effort to lock the rotation of the first body with respect to the second body.

At least some embodiments of the present disclosure an electrostatic sheet jamming device comprising a first sheet having a first conductive layer, a first dielectric layer disposed adjacent to the first conductive layer, and a second sheet comprising a second conductive layer and disposed proximate to the first dielectric layer. The first dielectric layer is disposed between the first conductive layer and the second conductive layer. The first sheet and the second sheet are non-extensible and flexible, wherein the first sheet and the second sheet are slidable relative to each other in a first state. The first sheet and the second sheet are jammed with each other in a second state when a voltage is applied between the first conductive layer and the second conductive layer. In some embodiments, the applied voltage is less than or equal to a break-down voltage of air at a distance between the first conductive layer and the second conductive layer.

An orthopedic device, first and second struts, and a range-of-motion limiting pivot assembly connecting to the first and second struts. The pivoting assembly having an engagement member linked to a tab disposed and arranged for pulling radially outward away from a central axis of the pivoting assembly for adjusting the range of motion of the pivoting assembly.

A brace includes a first member, a second member, a joint mechanism, and an insertion-fitting member configured to be insertion-fitted into the joint mechanism in such a manner that the insertion-fitting member can be fixed to and removed from the joint mechanism; the joint mechanism includes an insertion-fitting receiving part, the insertion-fitting receiving part being configured to enable the insertion-fitting member to be insertion-fitted into the joint mechanism, and a regulation part being disposed around the rotation axis in the second member; and the regulation part, which rotates around the rotation axis in an integrated manner with a rotation of the second member, comes into contact with the insertion-fitting member fixed to the insertion-fitting receiving part on a trajectory of the rotation of the regulation part, so that a range of the rotation of the second member is regulated.

A movable joint for use in a prosthetic or orthopedic system includes first and second joint sections arranged to rotate relative to one another. At least one shaft member is attached to and arranged to rotate relative to the first or second joint sections. A translating member is attached to the at least one shaft member. Translation of the translating member along a length of the at least one shaft member drives rotation of at least the first joint section and the second joint section.

A positioning device for arranging and orienting multiple securing elements on a base layer of a base body of an orthopaedic device. The positioning device includes a first holder having at least one receiving device for a securing element, and a second holder having at least one receiving device for a securing element, wherein the first holder and the second holder are mounted on one another such that they can swivel about a swivel axis about a restricted angular range starting from a starting position.

A robotic ankle system provides an assistive force for the heel-up portion of a user gait. Energy is stored in a spring responsive to a heel-on portion of the gait, and then released as the heel-up portion begins. In this manner, the gait of a user is assisted. The systems and methods are of particular use for those affected by stroke or in connection with rehabilitation activities.

The plantar flexure muscles assist device includes at least one drive mechanism (10) having a linear drive actuator (26); a latch mechanism (25) having a toothed annular surface coupled to the linear drive; a retractable rotating element having a toothed drum (24) and an elastic spiral element (23). The toothed drum has an annular groove and where the toothed drum corresponds to the toothed lock mechanism; a rope (28) wound in the annular groove of the toothed drum with one end attached to the elastic element (2); and a casing (21, 27) for containing the elements of the drive mechanism; a control system to send a signal to the linear actuator to activate or deactivate the locking mechanism, and a battery to supply power to the control system. The lightweight activation mechanism, together with the lightweight structure, allows the elastic element to store mechanical energy while the dorsiflexion movement occurs. This energy will enhance the plantar flexion movement, to increase physical performance on long and demanding walks and decrease user fatigue.
