Study Design. A prospective, case-control design.
Objectives. To develop a kinematic model that charac-
terizes frequently observed movement patterns in pa-
tients with low back pain (LBP).
Summary of Background Data. Understanding arthro-
kinematics of lumbar motion in those with LBP may pro-
vide further understanding of this condition.
Methods. Digital fluoroscopic video (DFV) was used to
quantify the magnitude and rate of attainment of sagittal
plane intersegmental angular and linear displacement from
20 individuals with LBP and 20 healthy control subjects
during lumbar flexion and extension. Three fellowship-
trained spine surgeons subsequently qualitatively analyzed
the DFVs to determine normality of movement. Final clas-
