Analysis system and method of joint movement

Abstract

A joint movement analysis system, comprising: a plurality of actual markers positioned around a joint, wherein space positions of the actual markers track space movement of virtual marker points that are set at anatomical bony landmark positions of the joint; 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 virtual marker points from the space movement data of the actual markers, and simulates and analyzes a movement of the bony structure of the joint according to the space movement data of the virtual marker points. The invention can dynamically analyze the joint movement condition, and the analysis result can track the actual joint condition objectively, quantitatively and accurately.
