A grip strengthening device having a finger portion for enhancing the grip by means of at least one artificial tendon arranged along at least one finger portion, wherein the finger portion comprises material along both sides and a tip, and possible along a dorsal side, the at least one artificial tendon is attached along both sides so that the artificial tendon may move, wherein the artificial tendon runs closer to a ventral side than the dorsal side of the finger portion, at least at positions corresponding to joints of a wearer's finger, the finger portion will transfer a force to provide a movement of the finger when the artificial tendon is retracted, wherein the artificial tendon runs in a detour towards or to a position in the middle between the dorsal and ventral side or closer to the dorsal side at a proximal portion of the finger portion.

Provided is a method and apparatus for setting a torque of a walking assistance apparatus. A rotation angle and a rotation angular velocity of the walking assistance apparatus may be measured to set the torque. An amount of torque to be set may be calculated based on the rotation angle and the rotation angular velocity of the walking assistance apparatus.

A sliding assembly may include a supporting frame having a proximal end and a distal end, a sliding frame partially inserted to the supporting frame, and a supporting member disposed between the supporting frame and the sliding frame to prevent the supporting frame from directly contacting the sliding frame, wherein the sliding frame is configured to move relative to the supporting frame.

An artificial joint for lower extremities, comprising an upper part, which has mechanisms for attaching to a user, and a lower part mounted thereon in a pivotal manner about a joint axis. The lower part can be bent in from an extended position into a flexed position. A force accumulator is associated with the joint and is loaded via a force transmission mechanism through a flexing movement of the upper part relative to the lower part and supports an extension movement of the lower part relative to the upper part at least over a part of the extension movement. The force transmission device exerts a maximum moment of extension at a bending angle between 45 to 80.

An assistance apparatus includes a first and second wires coupling an upper-body belt and a left knee belt to each other on or above a front and back parts of a body of a user, respectively, a third and fourth wires coupling the upper-body belt and a right knee belt to each other on or above the front and back parts, respectively, a motor, a first sensor that detects at least tensions of the first and third wires, and a control circuit. The control circuit controls the motor to generate, when the first wire is broken, in the second wire, a tension less than a tension of the second wire during no break in the first wire, and to generate, when the third wire is broken, in the fourth wire, a tension less than a tension of the fourth wire during no break in the third wire.

A hand orthosis for bending and/or stretching at least one finger of a patient's hand, comprising a force-introducing device fastened to a splint, which is coupled with at least one finger segment paired with the finger of the patient's hand, wherein the at least one finger segment comprises a plurality of modular members interconnected in an articulated manner. The modular members each have at least one bayonet link on a first front side and at least one bayonet hook, corresponding to the bayonet link, on a second front side for the formation of a bayonet connection between adjacent modular members providing a bayonet joint. In addition, the invention relates to a modular member for using in a hand orthosis and a method of producing a hand orthosis.

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.

A powered orthotic device for use with a limb having at least two joints includes at least two brace sub-assemblies. The first brace sub-assembly includes a first powered actuator assembly that receives a first sensor signal from an electromyographic sensor. The first powered actuator assembly applies a first force for driving sections positioned with respect to a first joint to move relative to one another. The second brace sub-assembly includes a second powered actuator assembly that is configured to receive a second sensor signal from a sensor selected from a group consisting of an electromyographic sensor, an inertial measurement unit, and combinations thereof. The second powered actuator assembly applies a second force for driving sections positioned with respect to a second joint to move relative to one another. The second force is based on the first sensor signal or the second sensor signal.

Provided is a power transmitting device including an input side gear assembly that includes a single power input terminal and two power output terminals, an output side gear assembly that includes two power input terminals and a single power output terminal, the two power input terminals configured to operate using power received from the two power output terminals of the input side gear assembly, respectively, and a stopper module configured to block power to be transmitted through one of two power transmitting paths connecting the two power output terminals of the input side gear assembly and the two power input terminals of the output side gear assembly.

Systems and methods are provided for supporting an arm of a user using a harness configured to be worn on a body of a user; and an arm support coupled to the harness configured to support an arm of the user, the arm support configured to accommodate movement of the arm while following the movement without substantially interfering with the movement of the user's arm. One or more compensation elements may be coupled to the arm support to apply an offset force to at least partially offset a gravitational force acting on the arm as the user moves and the arm support follows the movement of the user's arm, the one or more compensation elements providing a force profile that varies the offset force based on an orientation of the arm support.
