Dear Biomch-L Recipients,

Late in September I queried you for computer-based undergraduate
biomechanics laboratories that would illustrate basic kinematic
relationships of vertebrate bone-muscle systems.

As you can see, there is interest out there but not a lot of
material. Here's an opportunity for some enterprising computer
programmer/biomechanic.

Sorry for the delay in this posting. I didn't know how to compile
the messages. Here is my message and annotated responses.

MY ORIGINAL MESSAGE
>I am interested in a computer-based biomechanics simulation suitable
>for undergraduate biology students. I now use a kinematic model to
>collect basic data relating to vertebrate limbs (the foot). The lab
>illustrates the effect of the placement of muscle origin and
>insertion and joint position on speed mechanical advantage, force
>mechanical advantage and work output. I'm looking to put a little
>more zip into the exercise and to be able to enter measurements made
>on vertebrate skeletons. Can anyone direct me to the appropriate
>software, if available?

ANNOTATED RESPONSES:
1.
Please share any information that you get with me. I am currently
developing an undergraduate course in biomechanics, and I would like
very
much to include a lab like the one that you mention.

Thank you,

HI. I can't help you, but would certainly like
to see the collected responses. Thanks

You may wish to try Working Model software by:

Knowledge Revolution
15 Brush Place
San Francisco, CA 94103
(800)766-6615

It can do kinematic, static, and dynamic simulation of
simple machine elements as well as import AutoCAD drawings of
objects.
NOTE: I HAVEN'T BEEN ABLE TO GET A RESPONSE FROM THIS COMPANY DESPITE
REPEATED ATTEMPTS. IT SOUNDS PROMISING THOUGH.

I don't have any good leads for you, but please post to the list
whatever
you discover! I'd love to hear about it!!!!

We sell a software program for gathering and analyzing ground
reaction forces from Kistler from AMTI force platforms. We provide
the program with an analysis module which is actually a "crippled
version" of the program. It will not collect force data, but it will perform
all the other functions of the program, and is used by our customers for analyzing data they have
collected. The program is called FPS, and this analysis module is available
as FPS DEMO. The Demo version has sample files of human GRF's collected for
walking and running. Your students would be able to simulate collecting force
data and ten analyze it (pick peaks, plot curves, etc.). To extend its utility
beyond a few samples of walking and running data from humans you would
have to work with someone who has our software and a force plate and
would be willing to collect other sample data for you. We normally sell the
demo version for $10 but I'd be willing to provide you with a free version if
you think it would be helpful.

Scott Delp has a neat package which allows tendons to be
trasfered and new torque-angle plots to be obtained. See
his article in (I think( the Journal of Biomechanical Engineering.
NOTE: I COULDN'T FIND THE DELP PAPER. DOES ANYONE ELSE HAVE INFO
ABOUT THIS?
