View Full Version : Re: amputee running/cycling

Hello All, This is a very interesting and lively
discussion about technology in sports and in
particular how prosthetic technology fits into
the world of athletics. There is some very
pertinent work currently being done by a
colleague of mine here (Mindy Millard-Stafford
and her doctoral student, Beth Brown) along with
a recent graduate of our MS in Prosthetics and
Orthotics program (Andy Allison). They have
recruited elite amputee long distance runners and
measured their metabolic cost and economy with
different prostheses and compared to able-bodied
controls--an abstract from Beth Brown follows

Although it is true that not all athletes will
have access to this technology--I'm sure no
sprinter would be willing to lose a limb to be
able to use one of these prostheses--I think we
may be giving too much credit to the technology
and perhaps not enough to the athlete who has
overcome severe physical and social obstacles to
perform at these levels.
