Objectives: The aim was to explore the inter-reliability of a newly developed US scanning protocol (multimodal US) for the assessment ofdifferent aspects of sarcopenia-related muscle involvement, including muscle mass, muscle quality and muscle stiffness [using pointshear-wave elastography (SWE)], in patients with rheumatic and musculoskeletal diseases (RMDs).Methods: Quadriceps muscle mass (i.e. muscle thickness), muscle quality (i.e. muscle echogenicity evaluated with both a visualsemi-quantitative scale and a dedicated software package for image analysis, ImageJ) and point SWE measurements were obtained by tworheumatologists (blinded to each other’s evaluation) in consecutive RMD patients without previous/current myositis or neuromuscular disorders.Inter-reliability was assessed using the intraclass correlation coefficient (ICC) for continuous variables and Cohen’s kappa (j) for categoricalvariables.Results: A total of 45 RMD patients were enrolled [mean age 54.5 (16.0) years, male-to-female ratio 1:1.5, mean BMI 24.6 (4.6) kg/m2], 10 withPsA, 7 RA, 5 AS, 5 PMR, 4 SLE, 4 gout, 4 OA, 3 FM and 3 SSc. The grade of inter-rater reliability was excellent for muscle mass [ICC ¼ 0.969(0.953 < ICC < 0.979)]. Regarding muscle echogenicity, the agreement was substantial/almost perfect using the visual semi-quantitative scale(weighted linear ¼ 0.793, weighted squared ¼ 0.878) and excellent using ImageJ analysis [ICC ¼ 0.916 (0.876 < ICC < 0.944)]. Finally, a goodagreement was obtained for point SWE measurements [ICC ¼ 0.76 (0.712 < ICC < 0.8)].Conclusion: Multimodal US is a novel and reliable tool for the evaluation of different aspects of muscle involvement (muscle mass, musclequality and muscle stiffness) in RMD patients.
