JOINT MOVEMENT DETECTION SYSTEM AND METHOD, AND DYNAMIC ASSESSMENT METHOD AND SYSTEM FOR KNEE JOINT

摘要

A joint movement detection system comprises: a calibration device (1) used for setting an actual mark point at a set position around a joint and a virtual mark point at the anatomical characteristic position of a joint bony structure which can reflect the space movement condition of the joint bony structure; an optical sensing device (2) used for sensing a space position of the actual mark point so as to obtain space movement data of the actual mark point; a data collection device (3) used for collecting the space movement data of the actual mark point and space relative position data of the virtual mark point and the actual mark point; and a data analysis device(4) used for carrying out optimization operation on the movement data of the actual mark point so as to obtain space movement data of the virtual mark point and simulating and analyzing movement condition of the joint bony structure according to the space movement data of the actual mark point. The system can dynamically detect the joint movement condition and the detection result can reflect the actual joint condition objectively quantitatively and accurately.
