Comparison of ROMs and SI-ROM in FE analysis and biomechanical tests. a The contribution of intervertebral ROMs to the overall ROMs of C3–7 in FE models. The bottom of each column is the intervertebral ROMs of C3/4. The middle part of each column, filled by the dotted line, represents the ROMs of C4–6. And the upper part of each column, filled by the dotted line, represents the ROMs of C6/7. The contribution of each intervertebral ROM to the overall ROMs can be seen directly. b ROMs of C3/4; c ROMs of C6/7; d ROMs of C4–6; e overall ROMs of C3–7 in the biomechanical test; f SI-ROM of C3–7 in the biomechanical test. L-Bending: Left Bending; R-Bending: Right Bending; L-Rotation: Left Rotation; R-Rotation: Right Rotation. SI-ROM: the stability index ROM. Error bar represents 1 SD. *P < 0.05
