Measuring muscle quantity and quality is very important because the loss of muscle quantity and quality is associated with several adverse effects specifically in older people. Ultrasound is a method widely used to measure muscle quantity and quality. One problem with ultrasound is its limited field of view, which makes it impossible to measure the muscle quantity and quality of certain muscles. In this study, we aimed to evaluate the intra- and inter-rater reliability of extended-field-of-view (EFOV) ultrasound for the measurement of muscle quantity and quality in nine muscles of the limbs and trunk.
Two examiners took two ultrasound EFOV images with a linear probe from each of the muscle sites. The intraclass correlation coefficient (ICC) was used, and the standard error of measurement and coefficient of variation were calculated.
Intra-rater reliability was good to excellent (ICC = 0.2-1.00) for all muscle measurements. The inter-rater reliability for most of the muscle measurements was good to excellent (ICC = 0.82-0.98). Inter-rater reliability was moderate (0.58-0.72) for some muscle quantity measurements of the tibialis anterior, gastrocnemius, rectus femoris, biceps femoris and triceps brachii muscles.
Muscle quantity and quality can be measured reliably using EFOV US.
测量肌肉量和质量非常重要，因为肌肉量和质量的丧失与多种不良影响相关，尤其是在老年人中。超声是一种广泛用于测量肌肉量和质量的方法。超声的一个问题是其视野有限，这使得无法测量某些肌肉的肌肉量和质量。在本研究中，我们旨在评估扩展视野（EFOV）超声在测量四肢和躯干九块肌肉的肌肉量和质量时的观察者内和观察者间可靠性。
两名检查者使用线性探头从每个肌肉部位采集两张超声EFOV图像。使用组内相关系数（ICC），并计算测量标准误差和变异系数。
所有肌肉测量的观察者内可靠性良好至优秀（ICC = 0.2 - 1.00）。大多数肌肉测量的观察者间可靠性良好至优秀（ICC = 0.82 - 0.98）。胫骨前肌、腓肠肌、股直肌、股二头肌和肱三头肌的一些肌肉量测量的观察者间可靠性为中等（0.58 - 0.72）。
使用EFOV US可以可靠地测量肌肉量和质量。
