Discriminative Ability and Associations of Sarcopenia Using Point-of-Care Ultrasound with Functional, Mobility and Frailty Status in Older Inpatients.

ABSTRACT: Background/Objectives: We aimed to assess the discriminative ability of point-of-care ultrasound (POCUS) of the rectus femoris (RF) to detect sarcopenia and to examine associations of these sarcopenia measures with functional, mobility, and frailty status among older inpatients. Methods: Data were analysed from 161 patients aged 70 years and older consecutively admitted to a tertiary geriatric rehabilitation hospital between October and December 2023. The RF thickness and cross-sectional area (CSA) were measured using POCUS applying validated cut-offs. Ability of muscle ultrasound to detect sarcopenia based on bioelectrical impedance analysis (BIA) as the reference standard was calculated using receiver operating characteristics analyses (ROC). Second, associations of sarcope
