Hi All,

I posted the the following question on behalf of a
friend in UK about two weeks ago. I received
overwhelming e-mails from people who asked me to send
them a summary of whatever I recieve. on the other
hand I only received two following responses. in any
case, I have enclosed them. I thank you all for
replies.

Best Regards,

Alireza Abouhossein

Question:

Dear list members,

I am currently involved with developing a computer
model for the
movement of the thigh. I need to simulate the force
that each muscle exerts
in order to bring about flexion, extension, abduction
and adduction. I
am having a problem with trying to find a model that
can be used to
model the muscle. I have the force length, force
velocity and force
activation curves(from Winter 1990 and Zajac 1989)
along with the peak isometric contraction(based on the
PCSA from Dostal and Andrews 1982)of thigh muscles.
I also have a Hill type and Huxley type model for the
muscle mechanics from Zajac and a book called
Theoretical Consideration of Skeletal Muscle. I am
just not sure how i would use this information in a
commercial type package like ADAM to simulate movement
at the hip joint.

Hello Alireza,

This is in response your posting on biomch-l. You
should be able to perform a simulation of the forces
of the individual muscles in the thigh during various
movements using the AnyBody system. You can read more
about it at http://anybody.auc.dk. We already have a
pretty good model of the pelvis and lower extremity
tat could be used for the purpose.

I would be happy to provide you with more information
if you are interested.

Yours sincerely,
John
