A grasp assist system includes a glove having a glove palm and fingers, with the glove worn on a user's hand. A sensor measures flexion of the glove fingers, and thus a change of position and/or attitude of the fingers is determined. Finger saddles at least partially surround a phalange of a respective one of the user's fingers. The system uses one or more tendon actuators to pull on flexible tendons. Each tendon connects to a respective finger saddle. A controller is in communication with the actuators and sensor(s). The glove may use feedback from optional contact sensors to adjust tension, and may have a built-in restorative force. In executing a control method, the controller selectively applies tension to the tendons in response to finger flexion, via the tendon actuators, at a level sufficient for moving the user's fingers when the user executes a hand maneuver.

Rehabilitating an impaired body part of a subject such as a stroke patient includes systems, devices, and methods using an orthosis system configured to attach to the impaired body part and to move or assist in movement of the impaired body part. A control system is configured to operate the orthosis system in a mode in which the orthosis system first allows the subject to move volitionally or attempt to move volitionally the impaired body part in a predefined motion and then operates to move or assist in the predefined motion of the impaired body part. Additional modes of operation include a brain computer interface mode of operation and a mode in which the orthosis system operates in a continuous passive mode of operation comprising a plurality of repetitions of an exercise to move the impaired body part.

An apparatus for assisting a finger motion, including a palm support installed to surround a part of a hand-back and a wrist; an extension assist unit secured at a first side thereof to a middle phalanx region of a finger and connected at a second side thereof to the palm support to assist extension of the finger through an elastic force between both ends; and a flexion assist unit comprising a distal phalange support mounted on an end of the finger, and a first flexion wire and a second flexion wire mounted on a part of the finger and assisting flexion of the finger on the basis of tensile force supplied from an outside.

A mirror therapy device includes a first positioning assembly, a second positioning assembly and a transmission assembly connecting the first and second positioning assemblies. The first and second positioning assemblies are arranged in opposition to each other in such a manner that both are able to reciprocate. The first positioning assembly is configured for positioning of a healthy limb of a patient, and the second positioning assembly is configured for positioning of an affected limb of the patient. The transmission assembly is configured for power transmission between the first and second positioning assemblies so that the second positioning assembly moves in synchronization with the first positioning assembly under the action of the transmission assembly. A mirror therapy system includes the mirror therapy device and a display device. The mirror therapy system enables the healthy limb to drive movement of the affected limb to allow the affected limb to repeat the same movements as the healthy limb, thus establishing neural connections for synchronous vision, motor perception and proprioception of the patient's healthy and affected sides and better stimulating nerve recovery of the patient.

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.

This disclosure provides devices and methods for stretching that include an anchor configured to attached to a force providing element; a support, the anchor operably attached to the support; a plurality of finger traps operably attached to the support; and a wrist cuff operably attached to the support.

A grip strengthening device having a finger portion for enhancing the grip by means of at least one artificial tendon arranged along at least one finger portion, wherein the finger portion comprises material along both sides and a tip, and possible along a dorsal side, the at least one artificial tendon is attached along both sides so that the artificial tendon may move, wherein the artificial tendon runs closer to a ventral side than the dorsal side of the finger portion, at least at positions corresponding to joints of a wearer's finger, the finger portion will transfer a force to provide a movement of the finger when the artificial tendon is retracted, wherein the artificial tendon runs in a detour towards or to a position in the middle between the dorsal and ventral side or closer to the dorsal side at a proximal portion of the finger portion.

A rehabilitation feedback system is used during rehabilitation of one or more body appendages of a user. The system includes four finger tracking elements and a thumb tracking element supported for movement relative to one another so as to allow a user to performs a gripping motion when the elements are coupled to the fingers and thumb of a user. A biasing member provides a resistance force acting to urge each tracking element towards a starting position thereof. A visual barrier is adapted to hide the hand of the user at a first side of the visual barrier from direct visual sight by the user at a second side of the visual barrier. A sensor at the first side of the visual barrier detects movements of the tracking elements and communicates with an indicator element detectable by the user from a second side of the visual barrier.

Disclosed is an upper limb rehabilitation device. The device includes a grip portion provided to be held by a user's hand, and a grip-portion opening portion operating the grip portion to open or close the grip portion. The device further includes a pressing portion provided to be spaced apart from the grip portion. The pressing portion causes the user's hand positioned between the grip portion and the pressing portion to come into close contact with the grip portion. The device further includes a prop portion on which the grip portion and the grip-portion opening portion are seated, and an arm support portion configured to support a user's arm. The prop portion is connected at a first side thereof to the arm support portion, and the first side of the prop portion may be rotatably connected to the arm support portion.

A moving device for moving a human thumb, in particular for moving the thumb between a resting position and a grasping position. A thumb bending section is adapted to at least partially move the thumb between a flexed position and an extended position. The thumb bending section has a gear unit for transforming a rotation of a rotation element, which is rotatably mounted to a housing, into an essentially linear movement between a translation element and the housing. The thumb bending section further has a first flexion spring mechanically connected to the translation element and adapted to be fixed with a first proximal end of the first flexion spring relative to a human thumb at a position in a proximal distance to the metacarpophalangeal joint or at a position between the metacarpophalangeal joint and the carpometacarpal joint.
