Measurement of joint kinematics using ExpertVision system.
Three-dimensional kinematic calculations based on the output from a video-based passive marker detection system was developed. Three-dimensional position data of the markers placed on the limb were obtained with the system and then run through a program that calculated absolute and relative joint kinematics based on Eulerian angle and screw axis description. In this study, the accuracy and limitation of the system for kinematic analysis were examined.
