The technical term for this is Direct Segmental Multi-frequency Bioelectrical Impedance Analysis (DSM-BIA). It separately measures the impedance (resistance to alternating electric currents) of the trunk, arms, and legs of our body.
This new measurement concept measures the resistance of the cross point of two flows and takes the resistance values of the arms, legs and the body trunk.
Why is this important?
The human body is composed of five cylinders: the arms, the legs and the trunk. With the technology of the InBody, the trunk is directly measured. The trunk is occupied by various internal organs and its metabolic characteristics are different from the other parts of the body. Although difficult, it is important to precisely and directly measure the trunk, since the trunk has very low resistance compared to the arms and legs.
