Variability of walking and other daily activities in patients with total knee replacement

Abstract

BACKGROUND: Three-dimensional motion analysis has provided important information about functional outcome for patients who have undergone total knee replacement, yet many comparisons to control populations are inconclusive. Some of these findings may be explained by variability in patients' repeated performance, however this has not been previously reported. Therefore the objective of this study was to determine the variability of repeated performance in patients who have undergone total knee replacement during walking and selected activities of daily living using three-dimensional motion analysis. METHODS: The variability of kinematic and kinetic parameters over six repetitions of walking a..
