L2 – 3 | 15.8 | 0 | 5.3 | 1.8 |

Any level | 19.6 | 4.7 | 17.8 | 12.1 |
- Notes: LSR = lumbar segmental rigidity; LSI = lumbar segmental instability. Calculation of LSMD at 'any level' was only performed in cases in which all four motion segments were analysed. No patient had both LSR and LSI of either rotation or translation.
