People with transtibial amputation walked for 3-minute periods with different sock ply while their residual-limb fluid volume was measured using bioimpedance analysis. The results showed that approximately half of the people in the study experienced limb volume reduction with a sock added to their usual prosthesis and limb volume increase with the sock removed. Many subjects' residual limbs decreased in volume from the beginning to end of the session, and this decrease was related to the vascular health and presence of diabetes, obesity, and smok- ing. The results help shed light on factors that influence limb volume change during prosthesis use.
