A releasable gripping glove is provided having one or more flexible artificial tendons extending through a finger section of a glove body. The flexible artificial tendon is configured to maintain a structurally articulated configuration when the finger section is articulated. Each tendon includes locking teeth that engages with a releasable locking tab extending form a locking mechanism configured to engage the locking teeth when the finger section is articulated. A release mechanism is provided to engage and disengage the locking mechanism. A thumb release rod is positioned within a thumb portion and connected to the release mechanism. The articulating of the finger section releasably locks the flexible artificial tendon in the articulated position, which is releasable through relaxing of the thumb portion.

Orthoses, which are recommended for those suffering from spastic cerebral palsy to wear during sleep, may require manual adjustment and can cause discomfort while the wearer is trying to fall asleep. Accordingly, a patient-responsive orthosis is provided that includes a forearm splint, a hand actuator, a motor that extends the hand of the wearer by moving the hand actuator, memory that stores instructions, and a processor that extends the hand of the wearer in response to the instructions by causing the motor to move the hand actuator. The orthosis may include a sleep sensor and may be programmed to extend the hand of the wearer while the wearer is asleep. The patient-responsive orthosis may be programmed (e.g., by a clinician specifying a treatment schedule) using a remote device. The patient-responsive orthosis may also store and output usage data (e.g., for review by a clinician).

A wrist joint actuating structure of a hand rehabilitation device includes a palm orthosis body, a forearm orthosis body and a joint unit. The palm orthosis body includes a plurality of finger support rods and a thumb support rod. The joint unit is a universal joint and is connected between the palm orthosis body and the forearm orthosis body. The palm orthosis body can be turned an angle relative to the forearm orthosis body through actuation of the joint unit according to the bending degree of a user's wrist joint. A tension adjustment unit includes elastic members connected to the finger support rods and the thumb support rod. According to the different stretching tensions required by the fingers or the thumb for rehabilitation, the respective lengths of the other ends of the elastic members to be pressed by a fixing seat are adjustable, so as to adjust different stretching tensions.

An individual linkage mechanism for a finger of an exoskeleton glove with sections that are interconnected with joints to enable changing their mutual angular orientation, which linkage mechanism includes a first linkage attached to the glove, a second linkage connected to the first linkage through a first joint, a third linkage connected to the second linkage through a second joint, and a fourth linkage connected to the third linkage through a third joint, wherein the fourth linkage is provided with a finger orthosis, and the second linkage, the third linkage and the fourth linkage are capable to assume a mutually parallel placement wherein the finger orthosis is adjacent to the second joint at a farthest end from the glove, and the third joint is closer to the glove than the second joint.

An active orthotic device, e.g. a hand orthosis, is attached to one or more limbs of a human subject and comprises a respective set of actuators (21) for moving a respective limb (1A) among the one or more limbs. A method for controlling the orthotic device comprises obtaining one or more bioelectric signals, [S(t)], from one or more bioelectric sensors (10) attached to or implanted in the human subject; processing the one or more bioelectric signals, [5(t)], for prediction of an intended application force, FA(t), of the respective limb (1A) onto an object; obtaining a force signal, PA(t), from a force sensing device (22) associated with the respective set of actuators (21) and/or the respective limb (1A); and generating, as a function of a momentary difference, e(t), between the intended application force, FA(t), and the force signal, PA(t), a respective set of control signals, it(t), for the respective set of actuators (21).

A hand rehabilitation device includes at least one support to support a thumb and to perform a flexion/extension movement for rehabilitating the thumb. The flexion/extension movement is actioned by a first transmission mechanism to which the support is connected. The device further includes another support to support the index finger and to perform a flexion/extension movement for rehabilitating the finger. The flexion/extension movement is actioned by a second transmission mechanism to which the at least one second support is connected. The device further includes another support for the three remaining fingers which is configured to perform a flexion/extension movement for rehabilitating the three remaining fingers. The flexion/extension movement is actioned by a third transmission mechanism to which the at least one third support is connected. The three transmission mechanisms are actuated by a motor; and the three flexion/extension movements of the three supports are independent from each other.

A method for producing a hand orthosis, including the steps of: Producing an impression of at least one finger of a patient's hand and at least a part of a forearm, producing a finger section from a reproduction based on the impression, incorporating at least one finger segment in the finger section side corresponding to the hand surface, detecting the physiology of the patient's forearm using at least one captured image from the reproduction together with the finger section, thereby producing a digital 3D model, generating a rail based on the produced digital 3D model, securing at least one force-introducer onto or into the rail, securing a proximal end of the at least one finger segment to a distal end of the rail, and coupling the at least one force-introducer to the at least one finger segment. A hand orthosis is also provided.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, for generating, using, or both, exosuit historical data. In some implementations, (i) sensor data generated by sensors of an exosuit worn by a user and (ii) control data indicating actions performed by or control signals generated by the exosuit based on the sensor data while worn by the user are received. The sensor data and the control data are added to a database that includes historical data describing use of the exosuit over time by the user. A control scheme of the exosuit is customized for the user by updating the one or more machine learning models or settings that govern the application of the one or more machine learning models. Forces provided by one or more actuators of the exosuit are controlled using the updated one or more machine learning models or the updated settings.
