I wanted to thank the few people that responded to my inquiry about the
inertial properties of BK prostheses. While I did get a couple specific
replies (person to contact or an article reference), a couple others simply
wanted to exchange ideas. Below, you should find a list of the responses
I�ve received. I�ve also included a few of the references I�ve compiled in
case anyone is interested. Thanks again. � Jackie

Fellow listmembers -
I am interested in finding inertial properties for a few different types of
BK limbs. Specifically, I want to be able to change the anthropometry
section in a gait analysis software package to accomodate children with
prostheses. Normally, the foot and tibia portions are related to Winter's
anthropometric data, based on proportions of the subject's whole body mass.
While I have length measurements for a TT pediatric prosthesis with a SACH
foot (and overall weight of this limb), I don't have the mass distribution.
I would also be interested in finding the radius of gyration. I am
waiting for a few papers on this topic through interlibrary loan, but could
anyone else offer some insight? Thanks.
List of replies:
1) As a fellow oandp-l reader, I was struck by your request. My interest is
in prosthetic arms, but I was wondering whether you might have come across
anything in that vein in your reading. As an EE with a background in
robotics, I'm finding it very difficult to even know where to begin looking
for such inertial properties of prosthetic arms, etc. (That, and the fact
that our library consistently cancels journal subscriptions has left me
feeling quite frustrated!) Can you point in the right direction with regard
to references? I've thought about posting to the listserve and to
biomech-l, but the variability of the amputee population had me wondering
whether my searches had been futile because there hadn't been any work in
this area. Any thoughts? You help would be greatly appreciated!
2) Why don't you drop a line to Dr Tim Bach (LaTrobe University Australia)
He did his PhD thesis on just exactly this subject � inertial
charachteristics of lower limb prostheses. His email is
<Email Address Redacted> He is also a really nice bloke and would be I'm sure
happy to assist you.
3) Our biomechanics group has measured the inertial properties of
prosthetic legs and the methods are described in:
Lehmann JF, Price R, Okumura R, Questad K, deLateur BJ, Negretot A: The
effect of mass and mass distribution of below-knee prostheses on efficiency
of gait and on self-selected walking speed. Arch Phys Med Rehabil,
79:162-168, 1998.
4) I'm also planning to write a research paper on this subject (kind
of),during my residency. I intend to do most of the research on the effects
of changing mass distribution by changing feet, materials, etc. Would you
like to share some data?
