EFFECTS OF VARIOUS BIOMECHANICAL ERRORS ON COMPUTED JOINT KINETICS VALUES
Keywords: biomechanical errors, 3D ankle joint kinetics, running, simulation
AbstractInverse dynamics analysis has been widely used to evaluate the joint kinetics during various human movements. Several investigators have reported that the joint kinetic computations could be considerably affected by diverse biomechanical errors. Kim et al (2007) clarified the influence of measurement errors of Center of Pressure (CoP) location of force platform on calculated three-dimensional (3D) lower limb joint moment during walking. However, it is not yet clear how biomechanical errors, such as errors in CoP, Body Segment Parameters (BSP) and Joint Center Location (JCL) data, affect the calculated joint kinetics values. The purpose of this study was to clarify the influences of the alterations of anthropometric, kinematic, and kinetic variables on the magnitude and time-series curve patterns of the 3D ankle joint moment during human running.
