The negative exponential model parameters for Macaca fascicularis lumbar—lumbar intervertebral joints in flexion (adapted from Gal, 1993a)

Joint and sample size (N)A (degrees)B (kg N-1 m-1)
L1L2 (16)-16.1±1.006.0±1.9
L2L3 (17)-12.3±0.992.6±0.8
L3L4 (13)-14.5±1.832.4±1.1
L4L5 (13)-11.4±0.613.7±1.4
L5L6 (14)-10.3±0.6319.2±6.7
Mean (L-L)-12.9±1.106.8±3.2
L6S (15)-23.1±1.564.2±1.6
  • The mean values of A and B (see equation 2 and text for definitions) for L1L2 to L5L6, inclusively, are shown (±S.E.M.). These mean values were used to construct a mean bending equation for macaque lumber—lumber (L-L) intervertebral joints in flexion.

    The model parameters are also shown for the M. fascicularis lumbosacral joint in flexion (L6S) for comparison.
