Disclosed is a portable upper limb rehabilitation mechanical arm with a grading adjustment training function. The mechanical arm comprises a big arm component, a supporting component, a grading adjustment component, a small arm component, a wrist component and a hand component, wherein the big arm component comprises a big arm shell, a big arm back plate, a first big arm support and a second big arm support; the supporting component comprises a supporting base, an inner supporting rod, an outer supporting rod, a sealing piece, a reversing component and a connecting bolt group; the grading adjustment component comprises an elbow motor shell, an elbow joint motor and an adjusting component; the small arm component comprises a first small arm support, a second small arm support, a small arm back plate and a small arm shell.

A user attachment for an apparatus for gait rehabilitation providing a possibility for a user to receive support during walking in a walking direction. A harness is attached to the body of the user and can be connected to a weight supporting device. This connection is a driven attachment arm attached at the weight supporting device which can be detachably connected with the harness. The driven attachment arm is connected via a double parallelogram unit with the harness attachment element. A guiding attachment arm can be connected with the weight supporting device and can be detachably connected with the harness attachment element for a rotative connection of the driven attachment arm with the guiding attachment arm.

A method, performed by a wearable device, of outputting a torque includes obtaining a first angle of a first joint of a first leg of a user and a second angle of a second joint of a second leg of the user, calculating a first adjustment angle, based on an offset angle set for the first angle and the first joint, determining a first state factor associated with the first angle and the second angle, based on the first adjustment angle and the second angle, determining a first value of a parameter for adjusting at least one of a magnitude, a direction, and timing of a torque to be output, determining a first torque value, based on the first state factor and the first value of the parameter, and controlling a motor driver of the wearable device to output the first torque value.

Two vertical front posts and two vertical rear posts are mounted on a flat platform of the automated device. The front posts mounted in the horizontal guide are symmetrically moved by the spacing adjustment mechanism within the range between the position of the joined front posts to a dimension between their inner surfaces equal to the width of the wheelchair, and the moved apart position to a dimension where the width dimension of the wheelchair is located between the mechanical legs suspended on the front posts. On the inner surfaces of the front posts, there are vertical guides with a screw drive mechanism for pelvic height adjustment. The mechanical legs girdle the patient's lower limbs from the outside by pelvic control units that induce a symmetrically alternating movement of the hip joint hinges in both mechanical legs with ellipsoid trajectories, and by adjustable thigh and shin connectors and foot connectors.

An apparatus for the regeneration of knee joint cartilages has a support housing on which a slide part is displaceably held. The slide part has a holding and/or supporting apparatus for a leg region below a knee joint of a leg. Furthermore, a controllable movement drive moves the slide part to and fro relative to the support housing along a predefinable adjustment path. The adjustment path is predefined such that a defined compressive/tensile loading can be applied to the knee joint. The holding and/or supporting apparatus is suitable for fixing a foot in a manner free from rotation on the slide part, and/or the support housing forms a leg support which is suitable for forming a continuous supporting surface from the foot as far as a thigh region.

An interface system in an exoskeleton includes a base support, a strap assembly, and posterior strut. The posterior strut has a vertical member defining a lower end connecting to the base support, and an upper end connecting to first and second transverse members extending in opposed directions from the vertical member. The first and second transverse members connect to the strap assembly. The interface system is adapted to receive and support an assistive device adapted to augment a user's performance and mitigate repetitive strain injuries.

A leg actuation apparatus includes two driven axes, wherein onto each one a distal parallelogram mechanism is attached with one connector being attached in a torque proof manner, wherein the other end of the arm being rotatably connected to an intermediate axis. One proximal parallelogram mechanism is rotatably attached at each intermediate axis and at transfer axes connected to the leg attachment elements to be attached to the upper and lower leg of a user. The distal ends of the lower parallelogram mechanism and the distal ends of the upper parallelogram mechanism can freely glide along the respective first and second driven axis.

Support device for supporting at least one body part of a user at least in portions, optionally completely, comprising a support body, which comprises at least one support region for supporting at least one body part of a user at least in portions, optionally completely.

A medical device for providing oscillatory motion to an individual is provided. The medical device includes a holder that can hold one or more body parts of an individual and an oscillatory mechanism that can transmit an oscillating force to the holder. The medical device includes one or more sensors that provide information about the individual and one or more compliant components that are configured to allow movement of the one or more body parts that deviates from a movement of oscillation. The oscillating mechanism can dynamically change a frequency of an oscillation based on feedback from the one or more sensors. The oscillating mechanism can also dynamically change an amplitude of the oscillation based on feedback from the one or more sensors.
