Abstract

A system for analyzing movement of a joint includes: actual markers positioned around the joint, where space positions of the actual markers track space movement of virtual marker points; an optical tracking device that senses the space positions of the actual markers so as to obtain a space movement data of the actual markers; a data collection device that collects the space movement data of the actual markers and a relative space position data of the virtual marker points with respect to the actual markers; and a data analyzing device that obtains a space movement data of the space movement of the virtual marker points from the space movement data of the actual markers, and simulates and analyzes a movement of a bony structure of the joint according to the space movement data of the virtual marker points.
