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 invention discloses a wire-driven wrist three-degree-freedom training mechanism for rehabilitation of upper limbs, and relates to the field of upper limb rehabilitating mechanical structures. The wire-driven wrist three-degree-freedom training mechanism comprises a wrist executing mechanism, a wrist linking mechanism, a forearm mechanism and an elbow linking mechanism. The wire-driven wrist three-degree-freedom training mechanism disclosed by the invention adopts a wire-driven design, through comprehensive utilization of two rotation pairs in the training mechanism, wrist three-degree-freedom passive training is realized through two driving motors; through the implementation of the wire-driven wrist three-degree-freedom training mechanism, a patient can adopt a passive training manner to perform rehabilitating training of the upper limbs; the wire-driven wrist three-degree-freedom training mechanism is provided with a position compensation mechanism, and can be adapted to individual differences of different patients, so that the training effect and user experience of the patient are improved; the mechanism is simple, the radiation and noise of the motors are low, and mental pressure of the patient can be reduced.

A forearm and wrist fracture table includes base members, vertical bars, horizontal bars, an elbow support member and a hand support member. The vertical bars includes a first vertical bar and a second vertical bar attached to the support base members. The horizontal bars are attached between the support base members and vertical bars to provide horizontal stability and length adjustment between the support base members and the vertical bars. The elbow support member is attached to the first vertical bar to provide support for the elbow. The hand support member is attached to the second vertical bar to receive and support a hand extending from the elbow, wherein the fractured arm is supported between the elbow support member and the hand support member, wherein a surgeon is allowed to modulate an amount of needing pressure required to distract fracture fragments, and thereby reducing fracture and healing the fracture site.

A system and method for transmission of a signal for a powered assistive device has a sensor node with a wireless transmitter adapted for digitally transmitting a transmitted signal, the sensor node adapted for receiving and monitoring a sensor signal from a sensor attached to a user, and a master node with a controller and a wireless receiver for receiving the transmitted signal from the wireless transmitter. The master node processes the transmitted signal and communicates a control signal to the powered assistive device. The wireless transmitter transmits the transmitted signal at a first rate when the wireless transmitter adapted to transmit the transmitted signal at a first rate when the sensor signal is indicative of the rest state and to transmit the transmitted signal at a second rate when the sensor signal is indicative of the active state, the second rate being greater than the first rate.

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.
