A medical device for assessing and/or rehabilitating a human joint of an extremity includes a joint brace comprising a first support for coupling to an upper part of the extremity, a second support for coupling to a lower part of the extremity, and a rotatable joint connecting the first and second supports, and a mechanical device coupled to the first and second supports, the mechanical device configured for moving one or more of the first and second supports so as to rotate about the joint. In another alternative the medical device can include sensors located for making angle measurements between the first and second supports and for recording movement data and a computing device for receiving and storing the angle measurements and the movement data and for transmitting said data via a radio transmitter.

A garment of the present invention comprises a closed tensionable loop for stabilizing a human knee. The loop is arranged to freely move along a conduit within the garment and is provided with a tensioner. The conduit crosses over itself between the lateral and a medial side on the anterior of the leg at least one of above and below the knee to provide compression on the ligaments of the knee when the loop is tensioned. The conduit circles the lower leg at a distal region of the triceps surae, thereby providing an anchor to the lower leg. An anchor is provided at or above the thigh. A method for stabilizing the knee using the tensionable loop involves positioning the garment so as to ensure that the conduit follows a predetermined path on the leg that places the loop over at least one of the two collateral ligaments of the knee and the tensioner is operated to adjust the compression on the ligaments.

An adjustable knee ankle foot orthosis for unloading weight from a knee joint afflicted with osteoarthritis, thus reducing pain and improving mobility, comprising: an upper and lower frame connected by an unloading hinge assembly, optionally comprising a sensor and processor allowing for remote or automatic control of brace tension. In embodiments, the brace includes a user mechanism that is capable of adjusting a tensioning element while the brace is being worn. In other embodiments, electronic motors, sensors, and indicators may be included in the brace to improve brace performance and user interaction.

In one embodiment, the orthotic device can include a powered hand portion, a switching element, and a controller. The wearer can interact with the switching element to generate input signals for adjusting an operation of the powered hand portion. The controller can receive the input signals and generate control signals to accordingly adjust the operation of the powered hand portion. In some embodiments, a powered hand portion can be comprised of a plurality of linkages and at least one powered actuator to assist with an opening and closing of the hand portion. The plurality of linkages can be operated by at least one electric motor with quick-connect elements to link onto fingers of a user. In some embodiments, an electrically-actuated clutch mechanism can be affixed to an upper arm section and a lower arm section of an orthotic device. The clutch mechanism can be configured into different positions.

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.

An actuator-damper unit for use in orthotic or prosthetic devices. The actuator-damper unit includes a housing which may be fastened on the orthotic or prosthetic device and in which a cylinder is formed. A first piston is displaceably mounted in the cylinder and is coupled to a piston rod. The piston rod is disposed, via a first end, on the first piston and may be coupled, via a second end, to the orthotic or prosthetic device. The first piston separates two fluid chambers in the cylinder from each other and forms a piston-cylinder unit, wherein at least one further piston is coupled to the first piston in order to form at least one further, variable-volume fluid chamber.

A joint device with an upper part and a lower part which are mounted on each other so as to be pivotable about a pivot axis, a hydraulic unit secured on the upper part and the lower part, and a housing in which a cylinder is arranged. A working piston is arranged in the cylinder and is coupled to at least one spring mechanism which transmits tensile forces and compressive forces and which engages on at least one abutment arranged displaceably inside the cylinder.

A walking assist device includes a pair of link members rotatably connected to each other at an output shaft situated at a location corresponding to a knee of a user, one link member being fixed to a thigh side of the user, and another link member being fixed to a lower leg side of the user, a rotary damper that generates a resistance force that is conveyed to the output shaft and that acts against rotation of the link members around the output shaft, a one-way gear that limits the resistance force generated by the rotary damper to one of directions of the rotation of the link members around the output shaft, and a clutch that switches between conveyance and non-conveyance of the resistance force from the rotary damper.

The disclosure features wearable anatomical devices that include a sleeve formed of a first material, one or more conduits connected to the sleeve, where each conduit is formed of a second material and at least partially filled with a third material, and one or more adjustable members connected to the one or more conduits and oriented so that at least some of the one or more adjustable members are connected at multiple locations to the one or more conduits, where the one or more conduits are oriented along a longitudinal direction of the sleeve, where each adjustable member extends in a circumferential direction of the sleeve, and where each adjustable member can be selectively controlled to modify a deformation of the one or more conduits.

The invention relates to a hand orthosis (1) for assisting the movements of a user's hand. The hand orthosis comprises a soft glove (2) adapted to receive at least a part of the user's hand with finger sections of the glove receiving each of the user's fingers. It further comprises at least one actuator box (3), and a power transmission (4) for transferring forces from the at least one actuator box to different parts of the glove via exo-tendons (5). The exo-tendons are arranged on a dorsal side, on a palmar side, or on both a dorsal side and a palmar side of the glove. The exo-tendons are arranged so that the glove can assist flexion, extension, or both extension and flexion of the fingers, respectively and so that the exo-tendons act on the fingers to produce motion that mimics the movement of a human hand. The hand orthosis provides different grasp types, self- adaptation of the fingers' motion to the shape of the object, and physiologically appropriate distribution of finger forces.
