The invention relates a device for supporting two arms 4 of a user 2 wherein the device has two arm support elements 6, each of which has an arm shell 10 for placing on an arm 4, at least one passive actuator 26, which is configured to apply a force to at least one of the arm support elements 6, and at least one counter bearing 14 for the force to be applied, which comprises at least one counter bearing element 16 and at least two force transmission elements 18, which are configured to transfer a counter force from each of the arm support elements to the counter bearing element 16,

wherein the force transmission elements 18 are arranged on the counter bearing element 16 such that they can be moved relative to the counter bearing element 16, in particular they can be rotated about at least one rotational axis.

An interface system includes a support belt, a strap assembly, and a frame system. The frame system includes a first frame member and a second frame member. The first frame member and the second frame member each respectively have an upper attachment portion configured to have an assistive device attached thereto at a first shoulder mount assembly and a second shoulder mount assembly, respectively. The first frame member and the second frame member are each respectively connected to the strap assembly and extend downward contouring laterally and connecting to the support belt. The first frame member and the second frame member contour laterally in opposed directions. The first frame member is connected posteriorly to the second frame member through a pair of hinge arms joined at a pivot connection.

An exoskeleton for interfacing with a joint includes a base configured to be coupled to a user, a platform configured to be coupled to the user proximate the joint, and a plurality of substructures extending between the base and the platform. The substructures are actuated in parallel in order to move the platform.

An apparatus (10) for the rehabilitation, assistance and/or augmentation of arm strength in a user (U) comprises a support arrangement (12) for supporting the apparatus (10) on the user (U), a linkage arrangement (14) coupled to the support arrangement (12) and for coupling to an arm (A) of the user (U), and an actuation arrangement (16) for operating the linkage arrangement (14) and thereby manipulating the user's arm (A) in response to a user input signal.

An underactuated mechanism has a first rotoidal joint connected to a human torso and rotating about a first joint rotation axis, a hyper-redundant connection mechanism connected to the first rotoidal joint, and a second rotoidal joint rotating about a second joint rotation axis, coplanar with the first joint rotation axis. The second rotoidal joint is remotely actuated by a driven pulley and Bowden cables or by a direct drive actuation system with co-located motor, and is fixed to the hyper-redundant connection mechanism on one side and to a human arm on the other side. The hyper-redundant connection mechanism has at least three members. Two members of the at least three members are rigidly fixed to one of the rotoidal joints, respectively. All members are connected together by rotation joints with axes parallel to one another and arranged to connect one member to a successive member to form a rotation constraint.

A shoulder rehabilitation device includes an elongated structure and a force generator. The elongated structure is configured to support an arm of a patient, the patient being in a lying position. The force generator is mounted to the elongated structure and configured to apply a traction force on the arm in a distal direction relative to the arm. The elongated structure is rotatable about a pivot adjacent a shoulder joint of said arm. The force generator is further configured to control the traction force to be within a predetermined range.

A rehabilitation training apparatus and a rehabilitation training system are disclosed. The rehabilitation training apparatus includes a powertrain, a pneumatic flexible actuator and a receiving portion. The powertrain is coupled to the pneumatic flexible actuator and configured to rotate upon drive of the pneumatic flexible actuator. The receiving portion is coupled to the powertrain and configured to receive a training portion and be interlocked with rotation of the powertrain.

The present disclosure relates to an assisted exoskeleton rehabilitation device, comprising: a back structure comprising a back crossbeam, a back supporting panel with an adjustable length, and a shoulder pneumatic muscle element mounted on the back supporting panel; an arm structure; a shoulder joint assembly, by which the arm structure is connected to an upper end of the back structure; and a waist structure. An upper end of the back supporting panel is fixedly connected to the back crossbeam, and a lower end thereof is fixedly connected to the waist structure. The shoulder joint assembly comprises a curved shoulder joint connecting panel, a shoulder traction wheel, a shoulder traction line, a first hinge mechanism and a second hinge mechanism. One end of the shoulder joint connecting panel is connected to the upper end of the arm structure by the first hinge mechanism to form a bend-stretch revolute pair of the shoulder joint, and the other end of the shoulder joint connecting panel is connected to the back crossbeam by the second hinge mechanism to form an abduction-adduction revolute pair and a medial rotation-lateral rotation revolute pair of the shoulder joint assembly, and the shoulder traction wheel is fixed to the upper end of the arm structure. The shoulder traction line is connected at one end to the shoulder traction wheel, and connected to the shoulder pneumatic muscle element at the other end.

Examples of a device for guiding and detecting a motion of a target joints and a motion assistance system such motion guiding devices are described. The motion guiding and detecting device comprises a motion generator and a motion transfer and target interfacing unit to transfer the motion generated by the motion generator to the target joint. The system further includes a motion detection and feedback unit that interfaces with the target, and a controller that interfaces with both the feedback unit and the motion generator to control and coordinate the motion of the motion generator and the target joint.

A device for training and rehabilitation of a limb is provided. The device provides a board with a plurality of movement tracks to allow for controlled movement of the limb in various directions. Blockers and other controlling structures may be arranged on the device to limit range of motion of the movement of the limb.
