Many models have attempted to describe the forces which are experienced by the spine during work. However, most of these previous efforts have ignored the effects of trunk motion upon the spine loading process. This study observes the internal trunk loading key-event-times which occur when the trunk is moving at different angular velocities. These key-event times are statistically evaluated and used to form networks of event-time sequences which occur under the various velocity conditions. The significance of these sequences to spine loading is discussed.
