Question

The 4-electrode BIA method applies an electrical current at the distal electrodes on the hand and foot, and the voltage drop due to impedance is detected by the proximal electrodes on the wrist and ankle. True or False

Answer 1

The 4-electrode Bioelectric Impedance Analysis method involves applying electrical currents at distal electrodes and detecting voltage drop at proximal electrodes to measure body composition, and this statement is true.

Step-by-step explanation:

The statement is True. In the 4-electrode Bioelectric Impedance Analysis (BIA) method, an electrical current is indeed applied at the distal electrodes which are typically placed on a hand and a foot, and voltage drop due to impedance is measured by the proximal electrodes which are located on a wrist and an ankle. This method is used to determine body composition by measuring the rate at which electricity travels through the body, which is affected by the amount of fat, as fat impedes the electrical current more than lean tissue.
