Muscle measurements in daily clinical practice: correlations between ultrasound, bioelectrical impedance analysis and hand grip strength.

Objectives: Muscle ultrasound is gaining importance as a measurement tool to evaluate sarcopenia in daily clinical practice. This study sought to collect reference values of the biceps brachii (BB) in healthy subjects, and to correlate them to bioelectrical impedance analysis (BIA) and hand grip strength (HGS).

Methods: Ultrasound was used to measure muscle thickness (MT), cross-sectional area (CSA) and muscle stiffness (EG).
