Dynamic Segmental Kinematics of the Lumbar Spine

In vivo measurements of segmental-level kinematics are a promising avenue for better understanding the relationship between pain and its underlying, multi-factorial basis. The present work implemented a novel marker set used with an optical motion capture system to non-invasively measure in vivo segmental kinematics of the lower spine. Overall regional range of motion data and lumbar angular velocity measurement were consistent with previously published studies. Key findings from the work included measurement of differences in ascending versus descending segmental velocities during functional movements and observations of motion coupling paradigms in the lumbar spinal segments. The work contributes to the task of establishing a baseline of segmental lumbar movement patterns in an asymptomatic cohort as a necessary pre-requisite for identifying pathological and symptomatic deviations from the baseline.
