Comparisons of lumbar spinal stiffness from thrust onset to thrust peak during an HVLA-SM delivered at L4 (A1) or L6 (B1) between 3 joint conditions (laminectomy-only, laminectomy & 2 facet screws, laminectomy & 3 facet screws). Comparisons of the mean change in MIF (ΔMIF) during 5 manipulative thrust durations applied at L4 (A2) and L6 (B2) in 3 spinal joint conditions. 0ms thrust duration represents a time control. Data reported as means and SD. Lam., laminectomy, MIF, mean instantaneous frequency.
