Abstract :
It is shown that a significant potential for error exists when a single measurement from wrist to ankle is used to determine body water volume and percentage of body fat, and that by making measurements of multiple regions of the body (arms, legs, and trunk) a more accurate determination can be obtained. This concept is suggested by the results of multiple impedance measurements made on a group of 11 patients undergoing haemodialysis.<>
