An orthotic support comprises a shoulder section for encapsulating a first shoulder of a wearer, a glove section for conforming to at least a portion of the wearer's hand, and a sleeve section for conforming to the wearer's arm, the sleeve section connecting the shoulder section to the glove section. A resilient reinforcement extends from the glove section to the shoulder section, and at least a portion of the reinforcement extends in a spiral around the sleeve section, so that the reinforcement is configured to apply a rotational force to the wearer's arm, when worn, to urge a portion of the wearer's arm to rotate in a predetermined direction. The orthotic support may be usable to treat or prevent shoulder dislocation or subluxation, arm over-pronation or over-supination, wrist flexion or elbow flexion. An orthotic support may comprise a reinforcement with a first branch extending over an anterior portion of the sleeve section, and a second branch extending over a posterior portion of the sleeve section, so that the reinforcement is configured to urge the wearer's upper arm towards a rest position.

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.

An orthosis device having a metal wire adjusting structure includes a palm orthosis body and a forearm orthosis body. The palm orthosis body includes a plurality of fixing portions. A plurality of adjustment seats are connected to the fixing portions, respectively. The adjustment seats each have a first through hole for insertion of a first end of an elastic metal wire. A first adjusting bolt is screwed to the outer side of each of the adjustment seats, so as to tighten and secure the first end of the elastic metal wire. A second end of the elastic metal wire is inserted into a second through hole of a movable seat. A second adjusting bolt is screwed to the outer side of the movable seat, so as to tighten and secure the second end of the elastic metal wire. A finger sleeve is connected to the movable seat.

A device for the controlled assistance of the grip, including a first element, which can be worn on one hand, and which includes a pair of ferromagnetic plates. The device also includes a second element which includes a ferromagnetic core whose opposite poles are each connected to one of the two ferromagnetic plates. The device further includes a power supply unit connected to an excitation coil wound around the ferromagnetic core. A control unit controls the voltage supplied by the power supply unit to the ends of the coil, so as to adjust the magnetic field generated to the ferromagnetic plates.

A joint exoskeleton auxiliary driving mechanism has a first driving module. The first driving module has a first gear member, a first connecting member, a first rotating driver, a first linear driver, and a first motion element. The first connecting member is disposed on a side of the first gear member. The first rotating driver is disposed on the first connecting member and engages with the first gear member. The first linear driver is disposed on the first connecting member. The first motion assembly is connected to a first power output element of the first linear driver. The joint exoskeleton auxiliary driving mechanism has two degrees of freedom motion function such as forward rotation, reverse rotation, and dorsiflexion or extension, and has the advantages of structural simplification, precise strength controlling, lightweight, and miniaturization.

An orthotic device is provided which includes a first structural element; a second structural element which is rotatably attached to the first structural element across a joint; a first rotary actuator which imparts rotational motion to the first structural element relative to the second structural element about a first axis; and a second rotary actuator which imparts rotational motion to the first structural element relative to the second structural element about a second axis. Each of the first and second rotary actuators is selected from the group consisting of parallel eccentric actuators and rotary actuators.

In one aspect, an orthosis for increasing range of motion of a body joint generally includes first and second dynamic force mechanisms for simultaneously applying a dynamic force to body portions on opposite sides of a body joint.

A hand therapy system includes a substrate having a front opening, a rear opening and left side, right side, top and bottom surfaces. Provided to the surfaces are a station configured to exercise ability lock and unlock a door, a station configured to exercise opening and/or closing of a hand, at least one station configured to exercise fingertip thumb-finger oppositional gripping and rotating as well as size discernment, at least one station configured to exercise palmar gripping and supination and pronation and at least one station configured to exercise fingertip thumb-finger oppositional gripping and elbow extension and flexion as well as size discernment.

A wearable suit and control method thereof is disclosed herein. According to an embodiment of the present disclosure, a method of controlling a wearable suit including a muscular strength assistance unit, at least a portion of which is made of a shape memory alloy material, is provided, the method including: a heating process of heating the muscular strength assistance unit to provide auxiliary force to a user of the wearable suit; and a cooling process of cooling the muscular strength assistance unit to reduce the auxiliary force, wherein the cooling process is a process of cooling the muscular strength assistance unit based on an operating time of the user.

A convertible wrist rehabilitative training device for use with a stroke patient includes a base; a first adjustable wrist support that is configured to move between a first handle position for use in wrist flexion and extension training and a second handle position for use in ulnar deviation and radial deviation training; and a second adjustable wrist support that is configured to move between a first handle position for use in wrist flexion and extension training and a second handle position for use in ulnar deviation and radial deviation training. In addition, the device includes means for operatively coupling the first adjustable wrist support with the second adjustable wrist support such that motion of one of the first adjustable wrist support and the second adjustable wrist support as a result of movement of an unaffected wrist on an unaffected hand by the user causes the other of the first adjustable wrist support and the second adjustable wrist support and an affected wrist on an affected hand to move in a symmetrical motion.
