Purpose. The purpose of this study was two-fold; (i) To quantify the trunk posture misclassification error made as a function of angular distance from the posture bin boundaries, and (ii) To determine the effect these misclassification errors have on cumulative and peak love back load estimates from 3DMatch. The effect subject expertise had on posture matching ability was additionally examined. Tested variables included 'degrees away from boundary', 'expertise group', 'view', 'repetition number', and 'position'. Methods. Forty-five male and 45 female subjects were recruited from the University of Windsor. All subjects went through the boundary testing program viewing flexion/extension and lateral bend images. Subjects were instructed to make quick and accurate bin selections, and collected data were used to determine the effect errors had on subsequent 3DMatch outputs. Results. Subjects made more errors the closer a viewed image was to a boundary for both views, and significant effects were found for view and position. (Abstract shortened by UMI.)Dept. of Human Kinetics.
