With the development of modern motion analysis technologies, biomechanical analysis of human activities can be evaluated by motion camera system with relatively simple set of external reflective markers. In this study a three-dimensional (3D) marker-based whole body biomechanical model was developed to evaluate whole body activities. This model can be used with motion analysis system to provide mathematical description of the kinematics of body segments and conduct kinetic analysis. As an application, this model has been used to compute the lower back torque during manual asymmetric lifting activities.
