  • kinematics reference points

    I'm a graduate student working of a musculoskeletal model of non-human
    primates during locomotion. I'm looking for some anatomical reference
    points to use for my dissertation research project. Suggestions that
    would work for humans are most welcome, since these primates share many
    anatomical similarities with humans.

    I want to precisely define hip muscle function by capturing 3-D kinematic
    data of animals walking and combining it with anatomical data taken from
    carcasses. The anatomical data would establish the points of attachment
    of muscles as well as the hip joint center and the hip joint angle data
    would establish the lines of action of the muscles with respect to the
    hip joint center. To properly define hip position in three dimensional
    space I need 3 reference points on the pelvis and three on the femur.
    Ideally, I would chose 6 points that would (1) be easy to mark on a live
    animal (when it is asleep, of course), (2) be easily seen from either a
    front or side view, and (3) be easy to measure on the carcasses. A
    discreet bony protuberance such at the anterior superior iliac spine is a
    good example: it's an obvious surface anatomy feature on the species I'm
    looking at and it is a relatively discreet, measurable point on a
    carcass. The problem is I can think of only 2 good points on the pelvis
    and 2 good points on the femur; the two anterior superior iliac spines,
    the greater trochanter, and the center of the lateral condyle of the
    knee. So, I need another good point for the pelvis and another good
    point for the femur.

    I'll post a summary of all replies.

    Many thanks for any suggestions,
