Dear list members,
As I am an old partial foot amputee (Lisfranc), I have often heard that
a spring in the bottom of the prosthesis or in the sole of the shoeware
– sometimes in both – would be efficient. The spring will give a more
normal gait as before the push off there is a loading of energy by
bending, which can be used later during the push off moment.
I have some doubt about this function for partial foot amputees:
during the loading phase will be a hard pressure on teh plantar-distal
part of the foot, which not seldom is the most sensitive part. And
very much so if the prosthesis is only an insert with a filler.
Your comments are most welcome.
