We measured changes in fluid volume inside the residual limbs of seven people with transtibial amputations while they walked with their prosthetic limbs. Bioimpedance analysis, a new technique in the prosthetics field, calculated limb fluid volume change. Results showed that, in general, fluid volume decreased less or increased more when the participants used elevated vacuum sockets than when they used low vacuum or suction sockets. Time of day, soft tissue, socket size, type of socket normally worn, and health might also affect fluid volume changes inside residual limbs.
