    Hey, I think I can solve your problem!

    There are some really good papers by Lutz & company in the Spine journal
    on spine ROM. A good one in paticular is:

    Are sheep Spines a Valid Biomechanical Model for Human Spine? SPINE
    Vol22 #20,2365-2374 1997.

    From here there are a couple of really good ref. too.

    Hi Brad,

    I did some work on measuring sagittal plane thoracolumbar segmental ROM
    using videofluoroscopy when I was working at Aberdeen Royal Infirmary in the
    UK. You should be able
    to borrow a copy of my thesis, which contains complete details of the method
    and results:

    HARVEY S B, 1999, Interactive computer methods for morphometric and
    kinematic measurement of images of the spine, PhD thesis, University of
    Aberdeen, UK.

    There is also a published saggital plane thoracolumbar ROM study using
    low-field MRI:

    HARVEY S B, Smith F W and Hukins D W L, 1998, Measurement of lumbar spine
    flexion-extension using a low-field open magnet MRI scanner, Invest Radiol
    33: 439-443.

    Hope this helps.

    It's not my field at all, but I came across this article preparing for a
    viva with one of the authors, maybe it would be of some help:

    McGregor AH, Cattermole HR, Hughes SPF "Spinal motion in lumbar degenerative

    disc disease" (1998) JBJS 80-B (6) 1009-1013

    they used ISLs in clinic to see if disease had any effect on ROM of the
    lumbar spine.



    Search for work by Pearcy or Mellin maybe. Also, this may or may not be of
    help: BurtonAK, Tillotson
    KM. Reference values for regional lumbar sagittal mobility. Clin Biomech
    1988; 3: 106-113.

    You should have a look to the work of M.J. Pearcy in the 80's on the in vivo

    lumbar spine movement.
    I have 3 refs for you :

    -"Three-dimensional X-Ray Analysis of Normal Movement in the Lumbar Spine",
    Mark Pearcy, Ian Portek, Janis Shepherd, Spine, 1984;9(3):294-300
    -"Axial Rotation and Lateral Bending in the Normal Lumbar Spine Measured by
    Three-Dimensional Radiography", M.J. Pearcy, Tibrewal S.B., Spine,
    -"Axial Rotation of the Lumbar Spine and the Effect of Flexion. An in vitro
    and in vivo Biomechanical Study", R. Gunzburg, W. Hutton, R. Fraser, Spine,

    Could you please send me the answers from the others ?

    Dear Brad
    You could look up the work by Mike Troke who has used the spine motion
    analyser to collect a normative data base of lumbar spine range of movement.

    As far as I am aware there is no fixation of the pelvis, the fixation is on
    the sacrum.
    You will find an article by Mike in Manual Therapy 3 (1) in 1998. I have
    sent a copy of this e mail and he may send his other publications
