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 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.

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.

A chest compression device includes a piston to apply compression to the sternum and incorporates leaf springs simultaneously driven by the piston to apply lateral compression to the thorax during chest compressions. A motor in the chest compression device provides motive power to cyclically extend and contract the piston to provide therapeutic chest compressions. One end of each leaf spring is operably connected to the piston and the other end of each leaf spring is secured to the backboard/base or to a support leg of the chest compression device such that during extension of the piston, each leaf spring is compressed against the device base or leg which causes the springs to flex and provide lateral compression of the patient's thorax in addition to the sternal compression of the piston.

A walking support system includes: an information output device (260); a motion detector (220) which detects a motion of a user; a foot landing position detector (230) which detect a foot landing position of the user; a determiner (240) which determines a recommended foot landing position which is a landing position of the feet suitable for stabilizing motions of a gait of the user on the basis of motions of a gait of the user detected by the motion detector, the foot landing position detected by the foot landing position detector, and dynamics; and an output controller (250) which outputs information indicating the recommended foot landing position determined by the determiner to the information output device.

An apparatus and method are provided for imparting a repetitive motion to a user. The apparatus may include one or more seat platforms and one or more backrests. Repeated motion of the pelvis and shoulders of the user may be contra lateral. The motions of the user may mimic walking. The apparatus may include a chair. The apparatus may include a sensor. The sensor may be used to control the apparatus and/or the sensor may be used to adjust the movement regime according to the user. The apparatus may help for example, to mobilize limited mobility users and/or to train healthier habits.

A foot spa tub includes a tub basin, a first magnetic drive member rotatably coupled to a drive motor, and a first casing supporting the magnetic drive member. The first casing is disposed against an exterior surface of a sidewall of the basin. A second magnetic drive member is rotatably coupled to a blade. The first and second magnetic drive members are magnetically coupled to each other so that the blade is drivingly coupled to the drive motor. A nozzle houses the second magnetic drive member and the blade. The nozzle is detachably securable to an interior surface of the sidewall by a magnetic attraction force between the first and second magnetic drive members. A method of circulating liquid in a foot tub spa is also provided.

An external ear canal pressure regulation device including a fluid flow generator and an earpiece having a first axial earpiece conduit fluidicly coupled to the fluid flow generator, whereby the earpiece has a compliant earpiece external surface configured to sealably engage an external ear canal as a barrier between an external ear canal pressure and an ambient pressure.
