    Dear Members,

    I'm facing with the next problem, asking your help : I would like to compare the effect of an intervention on the free moment. As the values of the free moment are influenced by the subject velocity and possibly, by the intervention I would like to reduce the velocity's contribution through normalization. The only one reference regarding the velocity normalization I found in the case of angular momentum [ http://jeb.biologists.org/content/211/4/467.abstract ]. As there are big differences between subject velocities pre and post intervention I would like to ask you if free moment normalization with velocity x body weight x height could solve my problem. I would be grateful for any references on this subject. I've tried to find an answer on the biomch-l too, but without success till now!

    Thank you in advance for your help,

    Respectfully,
    Daniel

    Sorry to be slow, but what is "the free moment"? I'm not familier with the term?

    With you. So it's a measure of the torsion of the foot against the ground around a vertical axis.

    Thanks for clarifying.

    -not necessarily of the foot
    -around a vertical axis passing through CoP

    Sincerely,
    Daniel
