 As a reminder, force assignments must exist in a dynamic trial in order for gait events to be detected. In the force signal graph below, we are able to see the **LHS and LTO** gait events are highlighted. As a reminder, force assignments must exist in a dynamic trial in order for gait events to be detected.
