A Look at the Phase Angle Obtained by Electrical Bioimpedance

Electrical bioimpedance analysis is an easy, non-invasive and non-ionizing method, used for various purposes, including: analysis of body composition, malnutrition, sarcopenia, general health status and can enable the identification of conditions associated with diseases. One of the parameters derived from electrical bioimpedance is the phase angle, a physiological index that represents the relationship between the resistance (capacitance of body fluids and electrolytes against the electrical current) and the reactance (capacity of the cell membrane to maintain electrical potential) of cells and body tissues.
