B-mode ultrasound is often used to quantify muscle architecture during movements. Our objectives were to ) systematically review the reliability of fascicle length (FL) and pennation angles (PA) measured using ultrasound during movements involving voluntary contractions; ) systematically review the methods used in studies reporting reliability, discuss associated challenges, and provide recommendations to improve the reliability and validity of dynamic ultrasound measurements; and ) provide an overview of computational approaches for quantifying fascicle architecture, their validity, agreement with manual quantification of fascicle architecture, and advantages and drawbacks. Three databases were searched until June 2019. Studies among healthy human individuals aged 17-85 yr that investigated the reliability of FL or PA in lower-extremity muscles during isoinertial movements and that were written in English were included. Thirty studies ( = 340 participants) were included for reliability analyses. Between-session reliability as measured by coefficient of multiple correlations (CMC), and coefficient of variation (CV) was FL CMC: 0.89-0.96; CV: 8.3% and PA CMC: 0.87-0.90; CV: 4.5-9.6%. Within-session reliability was FL CMC: 0.82-0.99; CV: 0.0-6.7% and PA CMC: 0.91; CV: 0.0-15.0%. Manual analysis reliability was FL CMC: 0.89-0.96; CV: 0.0-15.9%; PA CMC: 0.84-0.90; and CV: 2.0-9.8%. Computational analysis FL CMC was 0.82-0.99, and PA CV was 14.0-15.0%. Eighteen computational approaches were identified, and these generally showed high agreement with manual analysis and high validity compared with phantoms or synthetic images. B-mode ultrasound is a reliable method to quantify fascicle architecture during movement. Additionally, computational approaches can provide a reliable and valid estimation of fascicle architecture.
B 型超声常用于测量运动过程中的肌肉结构。我们的目的是：）系统地回顾在涉及自愿收缩的运动中使用超声测量肌束长度（FL）和肌小节角度（PA）的可靠性；）系统地回顾报告可靠性的研究中使用的方法，讨论相关挑战，并提出改进动态超声测量可靠性和有效性的建议；）概述用于量化肌束结构的计算方法、它们的有效性、与手动量化肌束结构的一致性，以及优缺点。三个数据库被检索到 2019 年 6 月。研究对象为年龄在 17-85 岁之间的健康人类个体，研究在下肢肌肉等速运动中 FL 或 PA 的可靠性，且以英文发表。有 30 项研究（=340 名参与者）纳入可靠性分析。以多重相关系数（CMC）和变异系数（CV）衡量的组间可靠性为 FL CMC：0.89-0.96；CV：8.3%和 PA CMC：0.87-0.90；CV：4.5-9.6%。组内可靠性为 FL CMC：0.82-0.99；CV：0.0-6.7%和 PA CMC：0.91；CV：0.0-15.0%。手动分析可靠性为 FL CMC：0.89-0.96；CV：0.0-15.9%；PA CMC：0.84-0.90；CV：2.0-9.8%。计算分析的 FL CMC 为 0.82-0.99，PA CV 为 14.0-15.0%。确定了 18 种计算方法，这些方法通常与手动分析具有高度一致性，与人工制品或合成图像相比具有高度有效性。B 型超声是一种在运动过程中定量肌束结构的可靠方法。此外，计算方法可以提供可靠和有效的肌束结构估计。
