Longitudinal study on the relationship between extracellular water distribution changes and muscle mass in severe sarcopenia patients using multi-frequency bioelectrical impedance analysis combined with phase angle measurements

Multi-frequency bioelectrical impedance analysis combined with phase angle measurement offers a non-invasive and sensitive approach for early detection of muscle mass loss in severe sarcopenia. Shifts in electrical parameters and water distribution precede measurable muscle decline, highlighting a potential window for timely intervention.
