This review evaluates the reliability and validity of ultrasound to quantify muscles in older adults. The databases PubMed, Cochrane, and Cumulative Index to Nursing and Allied Health Literature were systematically searched for studies. In 17 studies, the reliability (n = 13) and validity (n = 8) of ultrasound to quantify muscles in community-dwelling older adults (≥60 years) or a clinical population were evaluated. Four out of 13 reliability studies investigated both intra-rater and inter-rater reliability. Intraclass correlation coefficient (ICC) scores for reliability ranged from -0.26 to 1.00. The highest ICC scores were found for the vastus lateralis, rectus femoris, upper arm anterior, and the trunk (ICC = 0.72 to 1.000). All included validity studies found ICC scores ranging from 0.92 to 0.999. Two studies describing the validity of ultrasound to predict lean body mass showed good validity as compared with dual-energy X-ray absorptiometry (r = 0.92 to 0.96). This systematic review shows that ultrasound is a reliable and valid tool for the assessment of muscle size in older adults. More high-quality research is required to confirm these findings in both clinical and healthy populations. Furthermore, ultrasound assessment of small muscles needs further evaluation. Ultrasound to predict lean body mass is feasible; however, future research is required to validate prediction equations in older adults with varying function and health.
这篇综述评估了超声在定量老年人肌肉方面的可靠性和有效性。系统检索了 PubMed、Cochrane 和 Cumulative Index to Nursing and Allied Health Literature 数据库中的研究。在 17 项研究中，评估了超声在评估社区居住的老年人（≥60 岁）或临床人群中肌肉的可靠性（n=13）和有效性（n=8）。有 4 项可靠性研究同时调查了内部和外部可靠性。可靠性的组内相关系数（ICC）评分范围为-0.26 至 1.00。最高的 ICC 评分见于股外侧肌、股直肌、上臂前肌和躯干（ICC=0.72 至 1.000）。所有纳入的有效性研究发现 ICC 评分范围为 0.92 至 0.999。两项描述超声预测瘦体重的有效性的研究显示与双能 X 射线吸收法（r=0.92 至 0.96）具有良好的有效性。本系统综述表明，超声是评估老年人肌肉大小的可靠和有效的工具。需要更多高质量的研究来证实这些在临床和健康人群中的发现。此外，还需要进一步评估超声对小肌肉的评估。超声预测瘦体重是可行的；然而，需要进一步的研究来验证在具有不同功能和健康状况的老年人中预测方程的有效性。
