 This foot segment should be set to "kinematic only" since the origin is not at the point of rotation (the mid point of the RIMM & RLM targets. The IORFoot analysis does not calculate kinetics, so no kinetic foot segment is described in this model. To create gait events, you will need a kinetic foot segment. An example of a kinetic foot segment is created in the sample download files for this tutorial. This foot segment should be set to "kinematic only" since the origin is not at the point of rotation (the mid point of the RIMM & RLM targets.
