We used a technique called bioimpedance analysis to test how quickly fluid volumes inside residual limbs changed while people wore their prosthesis. We tested 12 people with transtibial amputation in two test sessions in 1 day. Our results showed that the rate of fluid volume loss within test sessions of sitting, standing, and walking activities tended to be greater than that between sessions. This difference was greater for people who had peripheral arterial complications. Other factors that may influence within-day fluid volume change include being female, time since amputation, and not taking the socket off for extended periods.
