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.

A therapeutic motion device includes a support structure including a first support portion and a second support portion. The first support portion rotatably coupled to the second support portion and at least one of the first support portion and the second support portion is movable relative to the other of the first support potion and the second support portion. First and second actuation arms extend from the first and second support portions, respectively. An artificial muscle drive unit couples the first actuation arm to the second actuation arm, the artificial muscle drive unit including one or more artificial muscles expandable in a movement direction to provide a movement force to at least one of the first support portion and the second support portion.

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.

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.

A robot system for active and passive upper limb rehabilitation training based on a force feedback technology includes a robot body and an active and passive training host computer system. Active and passive rehabilitation training may be performed at degrees of freedom such as adduction/abduction and flexion/extension of left and right shoulder joints, and flexion/extension of left and right elbow joints according to a condition of a patient. In a passive rehabilitation training mode, the robot body drives the upper limb of the patient to move according to a track specified by the host computer, to gradually restore a basic motion function of the upper limb. In an active rehabilitation training mode, the patient holds the tail ends of the robot body with both hands to interact with a rehabilitation training scene, and can feel real and accurate force feedback.

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 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.

Disclosed is a hand and arm support assembly for use by a user or patient to rehabilitate a hand of the patient. The hand and arm support assembly includes a hand actuator assembly and a forearm rest assembly. The hand actuator assembly provides a support for a hand engagement assembly having a housing and hand actuator rod engagement members projecting upwards therefrom to engage the hand of the patient. The housing is rotatable to accommodate the position of the patient's hand and the rod engagement members are adapted to travel along slots towards and away from one another. The forearm rest assembly includes a first carriage and a second carriage to support the forearm and elbow of the patient. The first and second carriage can pivot about an axis relative to the housing to further accommodate the position of the patient's arm and elbow.

An upper limb rehabilitation training system integrating multi-source stimulation is provided and includes an upper limb rehabilitation body provided with first through fourth rigid rings, the first through fourth rigid rings are fixed with first rope knots, second rope knots, third rope knots and fourth rope knots respectively. The upper limb rehabilitation training system integrating multi-source stimulation simulates working principles of muscle more authentically by using linear drive method, and complies with laws of human kinematics. The linear drive method reduces many complex mechanical structures, and makes process of force transmission very easy. The upper limb rehabilitation training system integrating multi-source stimulation reduces weight of a rehabilitative robot, improves wearing comfort, and provides a basic guarantee for patients to devote themselves to rehabilitation training.
