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

<p>Colorimetric scale represents the induced displacement [mm]. (Right) Retained volumetric blood flow rate under anterior loading. The effect of anterior spinal compression on ASA and branch (L1 and L3) blood flow rates was assessed over the range of 0–6.5% 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).
