This study investigated the reliability of sonoelastography techniques in quantifying lower limb tendon elasticity. A literature search was conducted using PubMed, Web of Science and CINAHL. The quality of the selected papers was evaluated using the Guidelines for Reporting Reliability and Agreement Studies and the Quality Appraisal Tool for Studies of Diagnostic Reliability checklist. Reliability values were extracted and synthesized. Twenty-four studies were included and were divided by the two main technologies used: strain and shear-wave elastography. The overall methodological quality was questionable; all studies were at risk of bias. Highly variable results ranging from poor to excellent reliability were found for both technologies and for all tendons considered. Intra-rater reliability of strain elastography on the Achilles tendon and shear-wave elastography on the patellar and quadriceps tendon was adequate. Inter-rater, inter-session and inter-machine reliability was insufficient. Caution should be used when interpreting results from sonoelastography studies measuring lower limb tendon elasticity.
本研究旨在探讨超声弹性成像技术在定量评估下肢肌腱弹性中的可靠性。通过 PubMed、Web of Science 和 CINAHL 进行文献检索。使用《可靠性和一致性研究报告指南》和《诊断可靠性研究质量评估工具检查表》评估所选文献的质量。提取并综合可靠性值。共纳入 24 项研究，根据两种主要技术（应变和剪切波弹性成像）进行划分。整体方法学质量存在疑问；所有研究均存在偏倚风险。两种技术和所有考虑的肌腱均发现可靠性结果差异很大，从很差到很好。应变弹性成像在跟腱和剪切波弹性成像在髌腱和股四头肌肌腱的内观察者可靠性是足够的。外观察者、不同时间和不同机器的可靠性不足。在解释测量下肢肌腱弹性的超声弹性成像研究结果时应谨慎。
