I do not think fluid volume fluctuation is at all specific to amputees,
rather a normal biological phenomenon which becomes especially problematic
when the goal is to containin soft tissues (e.g. in a prosthetic socket) The
disruption of fluid moving mechanisms (veinous return, lymphatics, etc...)
via amputation surgeries can only exacerbate this normal condition to a
degree, if there is nowhere in a socket for the fluid to go, will it not
just move elsewhere??? I guess I am offering that, I do not believe we can
arrest the process of volume fluctuation, and as such should focus on better
management of this natural, necessary evil... Right now, the best we are
able to do is add or remove socks! I have no experience with the VASS
device, but I must applaud it as a different approach to a vexing issue.
