The purpose of this study was to investigate the effect of model complexity on the measurement of segmental kinematics. Three-dimensional marker coordinates from 13 cricket fast bowlers were used to drive an inverse kinematics routine in OpenSim using a 20-segment, whole-body model with the shoulder joint centres of rotation fixed within a rigid trunk segment. Adding shoulder joint translation to the model improved the fit of marker coordinates through the inverse kinematics routine and significantly changed joint angles throughout the body. Switching the rigid trunk for a model with anatomically appropriate levels of lumbar movement did not further improve the overall accuracy of marker coordinate reconstruction; however the shoulder extension angle was affected by approximately five degrees.
