The invention relates to the technical field of mechanical arm control methods, and discloses a muscle force evaluation and self-adaptive control method for a household remote control upper limb intelligent rehabilitation mechanical arm, which comprises the following steps: initializing a system, guiding the first elbow flexion by voice, and judging the anti-gravity capability according to an elbow joint flexion angle. Secondary elbow bending is carried out after different reverse resistances are applied, the resistance resistance is judged according to the elbow joint bending angle, a scale is converted into clinical muscle force classification, a main control board calculates self-adaptive traction force and realizes closed-loop control, meanwhile, whole-course data are uploaded to a cloud side, and remote terminal monitoring and parameter adjustment are supported; according to the invention, the evaluation logic conforms to the clinical standard, the detection precision is high, the system integration level is good, quantitative muscle force evaluation, individualized adaptive training and remote professional supervision can be realized, the system is suitable for household upper limb rehabilitation of stroke, nerve injury and postoperative patients, and the technical problems of inaccurate evaluation, fixed control and lack of remote management of existing equipment are effectively solved.

The utility model discloses a wrist joint angle measuring device which comprises a bottom frame placed on an object placing surface; the fixing frame and the bottom frame are connected and perpendicular to each other. The sliding seat group comprises a first sliding seat and a second sliding seat, the first sliding seat is movably arranged on the bottom frame, and the second sliding seat is movably arranged on the fixing frame; the second sliding seat is provided with a measuring scale; the elbow of a patient abuts against the first sliding base, the second sliding base is provided with a fixing part to fix the palm of the patient, the second sliding base is stressed to move along the fixing frame to drive the first sliding base to move, the wrist joint of the patient is bent, and a measured value is output through the measuring scale. The whole measurement process is completed under the driving of the first sliding seat and the second sliding seat, so that a patient can be more relaxed in the measurement process, the measurement process is simpler and faster, the workload of medical staff is reduced, and the measurement accuracy is improved through limitation of the bottom frame and the fixing frame.

The application discloses an automatic elbow extension and flexion teaching device based on bone joint and muscle simulation, and relates to the technical field of elbow extension and flexion teaching.The device comprises a skeleton simulation part, a muscle simulation part, a base, a support rod, a top plate, a fixing mechanism, a driving mechanism, an electronic universal watch and a processing module.The skeleton simulation part, the muscle simulation part, the fixing mechanism and the driving mechanism are all assembled on the support frame formed by the support rod and the top plate.In the application, the flexible support frame is integrally designed with the humerus simulation part and the ulna and radius simulation part, and the movable elbow joint is formed by the fish line penetrating through the through hole, so that the human elbow joint anatomical structure and the 0-150-degree physiological activity range are accurately restored.The muscle simulation part is filled according to the human muscle shape, and is accurately attached to the first magic tape and the second magic tape, so that the muscle and the skeleton are quickly assembled, and the user can directly observe the linkage relationship between the skeleton and the muscle.

The invention discloses an elbow reflex dynamic teaching model and method for demonstrating up-down motor neuron damage, and relates to the technical field of medical teaching equipment. In order to solve the defects that an existing demonstration model lacks a multi-state pathology comparison function and cannot realize rapid switching between a normal state and a pathology state, an arm model, a neck marrow model, a brain region model and a nerve conduction pathway model are fixed on a supporting skeleton; the receptor module simulates percussion stimulation and generates a trigger signal; the stepping motor is used for driving the arm model to execute an elbow bending action; the upper motor neuron regulation and control module indicates an inhibitory regulation and control effect of upper motor neuron on a neck marrow reflex arc through a visual signal; the control unit receives signals, executes control logic and coordinates actions of all the modules. The voice control module receives a preset voice instruction; the damage simulation module switches the working mode of the system based on the voice instruction; and the state display module displays the current working mode and running state of the system in real time. The device is used for elbow reflex teaching.

A body wearable brace, e.g. for resisting involuntary motion, adapted for allowing a user wearing the brace on his arm to dynamically move his or her upper arm, forearm, wrist and hand, comprising: an upper arm piece; a hand piece; an elbow flexion-extension joint that is rotatable relative to the upper arm piece around a first axis of rotation; a forearm pronation-supination joint that is rotatable relative to the forearm pronation-supination joint and the elbow flexion-extension joint around a second axis of rotation; an extension element extendable in a longitudinal direction; a wrist flexion-extension joint that is rotatable around a third axis of rotation. A first portion of the wrist flexion-extension joint is directly or indirectly connected to the extension element, and a second portion of the wrist flexion-extension joint is directly or indirectly connected to the hand piece.
