Table 5 Kinematic data for each segment, and reference intervals for diagnosis of LSMDs under a Gaussian between-subjects model from asymptomatic sample (n = 30).

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

  Mean (sd) Reference interval Mean (sd) Reference interval
L2 – 3 10.7(4.56) 1.63, 19.87 .079 (.04) -.002, .159
L3 – 4 10.0 (4.83) 0.34, 19.68 .066 (.04) -.022, .148
L4 – 5 8.2 (5.31) -2.44, 18.79 .058 (.03) -.011, .123
L5 – S1 6.8 (6.25) -5.71, 19.29 .032 (.04) -.046, .109
  1. Notes: Rotation data are measured in degrees. Translation data are measured in units of vertebral body depth. The radiographic image of one L2-3 segment and 2 L5-S1 segments were of insufficient quality for analysis. Reference interval is defined by 2 standard deviations either side of the mean.
