Results of stiffness tests and statistical comparison among three states.
| Movement | State | Mean values of stiffness (Nm/deg) | value* |
| Right rotation | Normal | | >0.05 | Single staple | | Double staple | |
| Left rotation | Normal | | >0.05 | Single staple | | Double staple | |
| Right bending | Normal | | (N&S) <0.05 | Single staple | | (N&D) <0.05 | Double staple | | (S&D) >0.05 |
| Left bending | Normal | | (N&S) <0.05 | Single staple | | (N&D) <0.05 | Double staple | | (S&D) >0.05 |
| Flextion | Normal | | (N&S) <0.05 | Single staple | | (N&D) <0.05 | Double staple | | (S&D) >0.05 |
| Extention | Normal | | (N&S) <0.05 | Single staple | | (N&D) <0.05 | Double staple | | (S&D) >0.05 |
