This system software synchronizes bilateral mechanical data to the platform in real time through wireless Bluetooth technology, dynamically presenting core biomechanical indicators such as bilateral symmetry of average muscle force peak torque and torque curve. It supports 43+ standardized biomechanical action patterns such as shoulder internal rotation and hip adduction, and comprehensively covers multi-dimensional muscle strength assessment of the seven major joints of neck, shoulder, elbow, wrist, hip, knee and ankle. Based on the intelligent analysis engine, it can automatically generate muscle force change trend reports and synchronize them to the cloud database, realize dynamic monitoring of training load and accurate quantification of joint isometric contraction peak torque, and provide a full-link data-driven solution for sports rehabilitation programs to optimize competitive sports ability diagnosis and biomechanical research.
