View Full Version : CoM position from trochanter marker

hi everbody,

to determine a runner's vertical center of mass trajectory by
integrating the vertical acceleration obtained from kistler force
plates, a good estimate of the initial position is needed.
given that the subject is standing still at the beginning of data
collection one could use anatomical landmarks for the estimation.

can someone advice a simple way of determining CoM's vertical initial
position of a standing human subject and/or provide reference?

would something like 'mean of left and right greater trochanter plus 5%'
be sufficient enough?

with data collection already completed, the athropometric information
I have on my subjects are body height and the typical anatomical
landmarks of the lower limbs; however, I don't have any information on
trunk or arms.

any help is much appreciated!

thanks and best regards,
suzi
