(Left) Representative surface plot of cervical spinal cord displacement under anteroposterior loading.

<p>Colorimetric scale represents the induced displacement [mm]. (Right) Retained volumetric blood flow rate under anteroposterior loading. The effect of anteroposterior spinal compression on ASA and branch (L1 and L3) blood flow rates was assessed over the range of 0–9.65% dural occlusion, and the resultant change in arterial blood flow rates were calculated based on the percent of the baseline value (blood flow rate with no compressive loading).
