Novel Hypothesis on Phase Angle as a Candidate Marker Associated with Physiological Reserve in Geriatric Patients in Long-Term Care
Background: Physiological reserve reflects the capacity of the organism to maintain homeostasis under biological stress. We suggest the hypothesis that phase angle derived from bioelectrical impedance analysis could be a potential objective marker of Physiological reserve. Methods: An analytical cross-sectional study was conducted in 45 older adults residing in long-term care units at Hospital Español de México (2025). Frailty was assessed with the FRAIL index, sarcopenia using EWGSOP2 criteria, functionality with …
