The application discloses a novel human-simulating flexible parallel wrist joint with redundant driving, and has the characteristics that the joint comprises a moving platform (1), an intermediate branch chain (2), a first driving branch chain (3-1), a second driving branch chain (3-2), a third driving branch chain (3-2) and a base (4). The application is based on bionics and bionically designs the bony structure and muscle system of a human wrist joint, adopts a rope driving mode, has a high stiffness bearing ratio, is driven redundantly and has good human-machine interaction performance. The joint can be pulled by three motors through external ropes, converts the rotation of the motors into the movement of the ropes through a movable pulley, realizes 2-DOF (degree of freedom) movement, and is suitable for occasions such as the end wrist joint of an industrial robot, a human-simulating arm wrist joint and an intelligent prosthesis.

To appropriately support participants' exercise during remote training or rehabilitation. [Solution] The control unit 40 includes a display control unit 41 that displays a model video of exemplary body movements on the display unit 31, a movement determination unit 44 that determines the difference between the participant's movements, which are performed in accordance with the model video displayed on the display unit 31, and the model video, a mind-body state estimation unit 45 that estimates the participant's mind-body state based on the participant's biological information, a factor estimation unit 46 that estimates the cause of the difference based on the type of difference and the participant's mind-body state if the movement determination unit 44 determines that there is a difference, and a stimulus determination unit 47 that determines the type and method of stimulus to be given to the participant in order to promote a change in at least one of the participant's visual system function, brain-nerve system function, and muscular system function, based on the estimation result of the factor estimation unit 46.

The utility model relates to the technical field of intelligent health protection, in particular to a wearable equipment control system for knee joint injury detection and pre-protection, which comprises a controller, an upper computer, a data transmission module, a signal acquisition module, a wearable module and an electrical stimulation module, and is characterized in that the controller controls the wearable module; the upper computer records, checks and modifies personal information and checks the electric quantity of the wearable module; the data transmission module is used for communication between the controller and an upper computer; the signal acquisition module acquires human knee joint movement conditions; the electrical stimulation module is used for stimulating a human muscle system, the system collects knee joint movement conditions in the movement process in real time through the wearable module, judges whether injury risks exist or not based on a knee joint injury early warning algorithm of a deep learning model, and if the injury risks exceed an injury risk threshold value, gives an alarm. If yes, the electrical stimulation module can automatically apply electrical stimulation to the corresponding muscle position, muscle groups are promoted to contract, knee joint restoration is helped, and knee joint ligament injury is monitored and prevented.

The invention provides a novel method for preparing a fish otolith specimen, and belongs to the field of biological specimen preparation. Comprising the steps of specimen fixation, head skin dissection and segmentation, head muscle dissection and segmentation, head skeleton exposure and dissection, muscle dissection, dehydration, degreasing, polymer infiltration, fixation, solidification and the like. More importantly, the spatial position relation and the connection mode of the otolith, the skull, the brain, the nerve and the muscle system are displayed in situ. The otolith can be processed in a non-destructive mode, the otolith can be taken out or put back, the flexible display effect that the same specimen can display the details of the otolith and can also display overall dissection association is achieved, and the teaching and scientific research value of the specimen is greatly improved.

The invention provides an orthopedic rehabilitation training system and method. The method comprises the following steps: acquiring original electromyographic signals and three-dimensional motion data of limbs when a target patient executes orthopedic standard rehabilitation actions; determining an activation time sequence mode of neuromuscles according to the original electromyographic signals, and determining multi-modal motion features based on the activation time sequence mode and the three-dimensional kinematics data; determining a motion function index of the skeletal muscle system in the current rehabilitation period based on the multi-modal motion characteristics, and determining a function recovery track of the skeletal muscle system of the target patient in different training load scenes in the next rehabilitation period; and generating a personalized rehabilitation instruction set according to the motion function index and all the function recovery tracks, and adjusting auxiliary torque output of the rehabilitation training equipment based on the personalized rehabilitation instruction set. By adopting the scheme of the invention, the recovery tracks under different training loads can be predicted through the multi-modal motion characteristics of the patient so as to dynamically generate the personalized instruction set to assist the patient in rehabilitation training.

Based on combination therapy, we propose a cell therapy that can significantly enhance the therapeutic effect of treatment for cerebrovascular disease, ischemic heart disease, or traumatic cerebrospinal nerve injury in subjects compared to conventional methods. [Solution] A cell preparation containing microglia and / or monocytes, which have the ability to promote angiogenesis and axon extension, is administered to the subject. By repeatedly implementing a bidirectional biofeedback loop between the nervous system and the musculoskeletal system, the effect of improving the motor function of the subject's brain, nervous system, and muscular system is enhanced.
