Table 8 Prevalence (%) of LSMDs in the RCLBP cohort under a normalised within-subjects model

From: Lumbar segmental mobility disorders: comparison of two methods of defining abnormal displacement kinematics in a cohort of patients with non-specific mechanical low back pain

  Rotation Translation
  LSR LSI LSR LSI
L2 – 3 2.8 8.4 7.5 14.0
L3 – 4 13.1 4.7 7.5 4.7
L4 – 5 10.3 8.4 16.8 13.1
L5 – S1 6.5 7.5 13.1 8.4
Any level 28.9 23.3 35.5 31.8
  1. Notes : LSR = lumbar segment rigidity; LSI = lumbar segmental instability; Calculation of LSMD at 'any level' was only performed in cases in which all four motion segments were analysed. 20 patients (18.7%) had both rotational LSR and rotational LSI, 26 patients (24.3%) had both translational LSR and translational LS.
