Accuracy of an Eight-Point Tactile-Electrode Impedance Method in the Assessment of Total Body Water
This 2002 cross-sectional study evaluated the accuracy of an eight-polar tactile-electrode bioelectrical impedance analysis (BIA) device (InBody 3.0) for estimating total body water (TBW) in 50 healthy adults. TBW measured via deuterium oxide dilution served as the reference. A predictive algorithm using whole-body resistance index at 500 kHz (height² /
