Abstract:
1. A method of using bioimpedance to measure, over time, volumetric changes of a residual limb of a person with a limb amputation over time, while the person is wearing a prosthetic socket on the residual limb, comprising the steps of: (a) injecting an alternating current into tissue of the residual limb, wherein the injection is made between two longitudinally spaced-apart points along the residual limb; (b) detecting a change in voltage at a plurality of points that are intermediate or coincident with the two spaced-apart points; and (c) based upon the change in the voltage, using a model for on a comparison between the alternating current and the change in voltage, determining a change in the volume of the residual limb over time.
