Measuring Dynamic In-Vivo Elbow Kinematics: Description of Technique and Estimation of Accuracy

BACKGROUND: The objectives of this study were to characterize the translational and rotational accuracy of a model-based tracking technique for quantifying elbow kinematics and to demonstrate its in vivo application. METHOD OF APPROACH: The accuracy of a model-based tracking technique for quantifying elbow kinematics was determined in an in vitro experiment. Biplane X-ray images of a cadaveric elbow were acquired as it was manually moved …
