Bioimpedance analysis was used to measure the residual limb fluid volume of seven
transtibial amputee subjects using elevated vacuum sockets and nonelevated vacuum
sockets. Fluid volume changes were assessed during sessions with the subjects
sitting, standing, and walking. In general, fluid volume losses during 3 or 5 min
walks and losses over the course of the 30 min test session were less for
elevated vacuum than for suction. Numerous variables, including the time of day
that data were collected, soft tissue consistency, socket-to-limb size and shape
differences, and subject health, may have affected the results and had an
equivalent or greater effect on limb fluid volume compared with elevated vacuum.
Researchers should well consider these variables in the study design of future
investigations on the effects of elevated vacuum on residual limb volume.
