  • rotating foot problem

    Dear listers,
    I would appreciate help in a problem we have with our horse data. I
    understand that horses may not be the may source of information, but I think
    the problem may be similar in humans.

    During the propulsion phase of the stance the foot or hoof of the horse
    rotates ca. 2cm into a compliant surface. What would I expect to be the
    difference in movement of the horse on a hard surface? No answer yet.
    I have tried to search for references on this in the human literature but
    have not been successful, can anyone help me or have a guestimate on these

    Can the foot in humans rotate into a surface?
    Would we expect a greater ability to create a propulsive force?
    How might this change stride length and stance time?
    What might happen to the moment about the foot joint and knee joint?

    My guestimate is the following:
    The foot will rotate in compliant surfaces and create a greater propulsive
    force. The time of contact of the foot will increase and the net moment
    about the foot joint will shift in time due to the greater horizontal
    Am I totally wrong....?

    Thanks for the help
