摘要： An upper limb rehabilitation training system integrating multi-source stimulation is provided and includes an upper limb rehabilitation body provided with first through fourth rigid rings, the first through fourth rigid rings are fixed with first rope knots, second rope knots, third rope knots and fourth rope knots respectively. The upper limb rehabilitation training system integrating multi-source stimulation simulates working principles of muscle more authentically by using linear drive method, and complies with laws of human kinematics. The linear drive method reduces many complex mechanical structures, and makes process of force transmission very easy. The upper limb rehabilitation training system integrating multi-source stimulation reduces weight of a rehabilitative robot, improves wearing comfort, and provides a basic guarantee for patients to devote themselves to rehabilitation training.

摘要： Artificial muscles comprising a body of dielectric elastomer, wherein the body contains a pair of microfluidic networks are presented. Each microfluidic network includes a plurality of channels fluidically coupled via a manifold. The channels of the microfluidic networks are interdigitated and filled with conductive fluid such that each set of adjacent channels functions as the electrodes of an electroactive polymer (EAP) actuator. By using the manifolds as compliant wiring to energize the electrodes, artificial muscles in accordance with the present disclosure mitigate some or all of the reliability problems associated with prior-art artificial muscles.

摘要： An embodiment includes an exoskeleton robotic system including: a first linkage; a bearing coupled to the first linkage; a joint including a motor configured to move the first linkage along the bearing; an axial load sensor configured to sense an axial force transmitted to the axial load sensor via the joint, the axial force including one of tension or compression but not torque; a bracket including first and second bracket locations and first and second arms; and a housing that includes at least part of the joint and which couples the bracket to the bearing. The bracket couples to the housing at the first bracket location and couples to the axial load sensor at the second bracket location. The first arm couples the second arm to the first bracket location, and the second arm couples the first arm to the second bracket location.

摘要： Systems and methods for closed-loop ultrasound imaging-based control are described herein. An example system includes an ultrasound transducer, and a controller operably coupled to the ultrasound transducer. The controller includes a processor and memory, the memory having computer-executable instructions stored thereon. The controller is configured to receive an ultrasound imaging signal associated with a subject's muscular activity from the ultrasound transducer; process the ultrasound imaging signal to obtain a feedback signal; and control a device interfacing with the subject based on the feedback signal.

摘要： 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.

摘要： Embodiments herein are directed to a system that includes a powered wheelchair, a user-worn exoskeleton, and a master controller. The master controller monitors the independent movements of the powered wheelchair and the user-worn exoskeleton. The master controller prioritizes the movement of the powered wheelchair and the user-worn exoskeleton such that only one of the powered wheelchair or the user-worn exoskeleton will have the priority to complete the intended movement. The master controller may coordinate movements between the powered wheelchair and the user-worn exoskeleton so to perform a plurality of predetermined programs. For example, assisting a user to sit within the powered wheelchair, to assist a user to stand from a seating position when outside of the powered wheelchair, and/or use the powered wheelchair as a guide for walking.

摘要： Two vertical front posts and two vertical rear posts are mounted on a flat platform of the automated device. The front posts mounted in the horizontal guide are symmetrically moved by the spacing adjustment mechanism within the range between the position of the joined front posts to a dimension between their inner surfaces equal to the width of the wheelchair, and the moved apart position to a dimension where the width dimension of the wheelchair is located between the mechanical legs suspended on the front posts. On the inner surfaces of the front posts, there are vertical guides with a screw drive mechanism for pelvic height adjustment. The mechanical legs girdle the patient's lower limbs from the outside by pelvic control units that induce a symmetrically alternating movement of the hip joint hinges in both mechanical legs with ellipsoid trajectories, and by adjustable thigh and shin connectors and foot connectors.

摘要： An apparatus for the regeneration of knee joint cartilages has a support housing on which a slide part is displaceably held. The slide part has a holding and/or supporting apparatus for a leg region below a knee joint of a leg. Furthermore, a controllable movement drive moves the slide part to and fro relative to the support housing along a predefinable adjustment path. The adjustment path is predefined such that a defined compressive/tensile loading can be applied to the knee joint. The holding and/or supporting apparatus is suitable for fixing a foot in a manner free from rotation on the slide part, and/or the support housing forms a leg support which is suitable for forming a continuous supporting surface from the foot as far as a thigh region.

摘要： 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.
