[0002] Periarticular lesions and external trauma can lead to joint stiffness. Joint stiffness is manifested by varying degrees of impairment of normal joint function, reduced range of joint motion, and increased joint torque. Joint stiffness seriously affects people's daily production and life.

[0003] At present, common animals are used as research vehicles for human joint stiffness diseases, and the pathogenesis of joint stiffness is studied in depth. The evaluation of joint stiffness usually requires the measurement of two important indicators: joint range of motion and joint force. However, the currently known joint stiffness evaluation platforms can only obtain joint range of motion, but not the important indicator of joint force. In addition, most of the current experimental platforms cannot realize the evaluation of joint stiffness of animal limbs in multiple sizes, and the reliability of limb fixation and the coincidence of the joint center and the measurement center are ignored during measurement. Therefore, in order to realize the simultaneous and accurate measurement of joint range of motion and joint force related to joint stiffness and the adaptability measurement of multiple sizes of limbs, it is urgent to develop an animal joint stiffness index test platform.
