Muscle measurements in daily clinical practice

Journal Contribution - Journal Article

Subtitle: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). Lean mass (LM), fat mass (FM) and phase angle (PhA) were measured by BIA. HGS was measured using a Jamar dynamometer. Intrarater reliability was calculated using intraclass correlation (ICC). Correlations were investigated using Pearson correlation (PCC). Results: One-hundred-twenty-three Caucasian individuals (51 men, 72 women) between 18 and 69 years old were included. ICC for ultrasound was 0.99 (CI 0.98-0.99). LM, PhA and HGS showed significant correlations with MT and CSA in the entire population (PCC > 0.684). These correlations were more significant and stronger in men than women (PCC > 0.419 and >0.279 resp.). Significant correlations with respect to FM and EG were seen exclusively in women. Conclusion: Significant correlations were observed between parameters of muscle quantity measured by ultrasound, BIA and HGS. Intrarater reliability was excellent. Future studies in larger populations are needed to clarify the observed gender differences.
