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.

Examples of a device for guiding and detecting a motion of a target joints and a motion assistance system such motion guiding devices are described. The motion guiding and detecting device comprises a motion generator and a motion transfer and target interfacing unit to transfer the motion generated by the motion generator to the target joint. The system further includes a motion detection and feedback unit that interfaces with the target, and a controller that interfaces with both the feedback unit and the motion generator to control and coordinate the motion of the motion generator and the target joint.

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.

An elbow joint boost device has first and second frames to be attached to the forearm and lower arm of a patient. A guide mounted on the first frame extends generally along the respective one of the forearm and upper arm. A link is mounted on the guide for sliding movement along the guide, and a spring acts in tension between the sliding link and a point on the second frame remote from the patient's elbow. As the patient straightens and bends the elbow, the link can slide along the guide, varying the leverage of the tension spring.

Proposed is a rehabilitation exercise device for upper and lower limbs. The rehabilitation exercise device is characterized by including: a first support supporting a user's hand or foot; a second support supporting a user's forearm or calf; a pair of first hinges rotatably connecting the first support and the second support to each other; a third support supporting a user's upper arm or thigh; a pair of second hinges rotatably connecting the second support and the third support to each other; and a distance adjustment part configured to adjust a distance between the first support and the third support by adjusting length of the second support.

An orthopedic system wherein a patient's brain is operably coupled to an actuation assembly for voluntarily moving a brace/limb of the patient between a number of desirable positions. An orthopedic brace, or one of more components thereof, which can be utilized with the orthopedic system.

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.

An orthosis provides a wearer at least one of forearm supination, forearm pronation, shoulder internal rotation, shoulder external rotation, shoulder adduction, shoulder abduction, shoulder flexion, shoulder extension, elbow flexion, and elbow extension. It includes a shoulder assembly adapted to be secured to a wearer's shoulder and an upper arm assembly connected to the shoulder assembly and adapted to be secured around a wearer's upper arm. The upper arm assembly defines an upper arm assembly axis. A wrist assembly is adapted to be secured around a wearer's wrist. The wrist assembly defines a wrist assembly axis. A splint arm assembly includes an upper splint arm, a lower splint arm, and a pivot pivotally connecting the upper splint arm to the lower splint arm. The upper splint arm adjustably connects to the upper arm assembly and the lower split, arm adjustably connects to the wrist assembly.

A device is provided for manipulating an arm of a user, thereby providing extension or flexion assistance to the arm about an elbow. The device has an arm engagement system, having an upper arm member with an upper arm frame having a pivot end and a distal end, a posterior elbow pad, a forearm member with a forearm frame having a pivot end and a distal end and a distal wrist pad, and a pivoting connection operatively coupled with the pivot end of the upper arm frame and the pivot end of the forearm frame. A force application system having a force applicator is connected between the distal end and the pivot end of the forearm frame. A force application mechanism is connected at or near the distal end of the upper arm frame.

An upper torso orthotic device having multiple adjustment mechanisms configured to enable adaptation to a wide variety of body shapes, sizes and augmentation needs. The upper torso orthotic device including a body worn support frame member configured to dynamically distribute a weight of the upper torso orthotic device across the chest, shoulder and back of a user, and a limb augmentation member configured to augment a native strength of an arm of the user by overcoming the effects of gravity, the limb augmentation member including an adjustable shoulder assembly including at least one of a leveling mechanism, a clavicle retraction/protraction angle adjustment mechanism, a shoulder abduction angle adjustment mechanism, and a shoulder width adjustment mechanism.
