 For a lower-body model, an ankle joint angle is calculated using the foot as the segment and the shank as the reference segment. The X component represents flexion and extension for the segment coordinate systems used in this example. See [[visual3d:tutorials:kinematics_and_kinetics:model_based_computations|Model Based Computations]] for more information about joint-angle definitions. For a lower-body model, an ankle joint angle is calculated using the foot as the segment and the shank as the reference segment.
