Determining the biomechanical demand of tasks that involve a wide range of postures typically requires the use of motion capture techniques to accurately measure the range of body positions throughout the task. Although there is obviously motion involved in such tasks, a biomechanical analysis can be performed using quasi-static methods provided the tasks do not involve significant accelerations. One commercial software tool for performing such analyses is the Three Dimensional Static Strength Predictor Program (3DSSPP) produced by the University of Michigan. While the postural data obtained via motion capture methods can be manually input into 3DSSPP, this typically involves either the use of a two-dimensional projection of the three-dimensional visual image to estimate the joint angles, or the user may perform a visual comparison of an actual image of the task with the 3DSSPP image to obtain matching postures in the two programs.
