A novel shoulder brace that can provide active dynamic support to an injured shoulder while providing the capability to also raise the attached arm and support the arm in an elevated position. The brace can be used both in conjunction with a rehabilitation intervention program to maintain or restore range of motion and strength and to assist in functional tasks at work and at home. The brace works by supporting a locking or ratchet mechanism connected to an arm cuff from a chest piece that, when desired, the user can move the arm connected to an injured shoulder and supported by the arm cuff from a normal side resting position to an elevated position 90 degrees from the resting position while transferring the load created by the arm and whatever the hand is holding back to the chest piece and to the torso of the user. A release mechanism can be used to release the locking or ratchet mechanism to let the user lower their arm back to a resting position.

This application relates to an actuation system for assistive wearable devices such as exoskeletons designed to actuate a joint of a wearer of the device. The actuation system includes a differential pulley drum having a first drum portion and a second drum portion, the first drum portion and the second drum portion having different radii. The differential pulley drum is located at a first end of the actuator. The actuation system further includes a motor coupled to the differential pulley drum and configured to rotate the differential pulley drum, a second pulley located at a second end of the actuator, a flexible sleeve that extends between the differential pulley drum and the second pulley, and a strand that extends from the differential pulley drum to the second pulley through the flexible sleeve.

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.

The present disclosure discloses an unpowered wearable walking assistance knee equipment with gait self-adaptivity comprising a left foot power output assembly, a right foot power output assembly, a left leg knee joint assistance execution assembly, a right leg knee joint assistance execution assembly and a driving force transmission device. The equipment of the present disclosure is based on lever principle and crank block structure principle and adopts an operation mode of combining ipsilateral parallel driving input and different sides cross driving input. The self-weight of the human body is utilized as a driving force during the walking process to enable the left foot power output assembly to provide the left leg knee joint assistance execution assembly with a pulling force for its stretching and to provide the right leg knee joint assistance execution assembly with a pulling force for its bending, and to enable the right foot power output assembly to provide the right leg knee joint assistance execution assembly with a pulling force for its stretching and to provide the left leg knee joint assistance execution assembly with a pulling force for its bending, so that a torque for assisting the stretching and bending of the left leg knee joint and the right leg knee joint is generated according to a gait cycle regularity during the walking process, and the goal of walking assistance is achieved.

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.

This invention pertains to therapeutic or medical devices to improve healing, performance, or aesthetics by enhancing blood circulation to regions of the body. Blood circulation is enhanced using gravity by gradually raising and lowering the body member slowly and repeatedly from a level below the heart to a level above the heart.

A method and apparatus for rehabilitation and training of an injured limb by using the corresponding functional healthy limb to control the motion of the injured limb are presented. A sensor system on the healthy and active limb, a processing unit, and a power supply are provided in the apparatus to provide signals that activate a powered mechanism configured for moving individual bones on the injured passive limb.

An upper-limb rehabilitation assisting device includes first and second handles coupled to first and second rotating shafts and rotationally operated by hands on a paralytic limb side and a healthy limb side; first and second biosignal detecting parts that detect first and second biosignals corresponding to the paralytic limb side and the healthy limb side; first and second drive parts that drive the first and second rotating shafts; and a control part that performs a cooperative control of the first rotating shaft and the second rotating shaft. The control part controls the torques of the first and second drive parts at the time of the cooperative control of the first and second rotating shafts the basis of the degree of cooperation between the first and second biosignals.

This invention relates to methods, apparatuses, systems for boosting and stimulating the motion of weaker body parts of a person or animal by harvesting the power or strength of stronger body parts. It describes mechanisms for harvesting, storage and release of energy from one part of the body to another part of the body. A preferred embodiment of the present invention describes harvesting through mechanical means, storage through mechanical means and release through mechanical means to help harness energy from one strong part of the body to boost the muscular power of a weaker part of the body.

Patient aid devices and an associated method of supporting an upper extremity are described and include a mobile upper extremity support for the patient. A support assembly supports a first side of an upper body of the user for movement along a first rail. The support assembly also allows motion of a second side of an upper body relative to the first side.
