Ultrasonography is an economical and non-invasive method for measuring real-time joint movements. Although physiotherapists are increasingly using ultrasound imaging for rotator cuff disorders, there is a lack of evidence on their reliability in using ultrasonography to measure glenohumeral translation.
The aim of this study was to evaluate the reliability of a physiotherapist in measuring anterior and posterior glenohumeral joint translation with ultrasound.
Study design: within day reliability. Anterior and posterior glenohumeral translations were measured at rest, in response to passive accessory motion testing force, and with isometric internal and external rotation in 12 young healthy adults. All the measurements were made in real time by a physiotherapist and an experienced sonographer in two positions (neutral and abducted) and in two views (anterior and posterior). Intra-rater and inter-rater reliability were expressed using intraclass correlation coefficients (ICC) and measurement error (mm).
Intra-rater reliability was good for both raters (ICC: 0.86-0.98; ICC: 0.85-0.96). The inter-rater reliability between the physiotherapist and sonographer was moderate to good for posterior measurements (ICC 0.50-0.75) and poor to moderate for anterior measurements (ICC 0.31-0.53). For both intra-rater and inter-rater measurements, posterior translation was more reliable than the anterior translation with smaller measurement errors (posterior: 0.1-0.2 mm, anterior: 0.2-0.3 mm).
A physiotherapist with minimal training was reliable in measuring glenohumeral joint translations. The ultrasound method was reliable for repeated measurement of both anterior and posterior glenohumeral translations with posterior measurements being more reliable than anterior. This method is recommended for future research to investigate the stabilising role of rotator cuff muscles.
超声检查是一种用于测量实时关节活动的经济且无创的方法。尽管物理治疗师越来越多地将超声成像用于肩袖疾病，但缺乏关于他们使用超声测量盂肱关节平移可靠性的证据。
本研究的目的是评估物理治疗师使用超声测量盂肱关节前向和后向平移的可靠性。
研究设计：日内可靠性。在12名年轻健康成年人中，测量了静息时、被动附属运动测试力作用下以及等长内旋和外旋时的盂肱关节前向和后向平移。所有测量均由一名物理治疗师和一名经验丰富的超声检查人员在两个位置（中立位和外展位）和两个视图（前视图和后视图）下实时进行。使用组内相关系数（ICC）和测量误差（mm）表示评分者内和评分者间的可靠性。
两位评分者的评分者内可靠性均良好（ICC：0.86 - 0.98；ICC：0.85 - 0.96）。物理治疗师和超声检查人员之间的评分者间可靠性对于后向测量为中等至良好（ICC 0.50 - 0.75），对于前向测量为差至中等（ICC 0.31 - 0.53）。对于评分者内和评分者间测量，后向平移比前向平移更可靠，测量误差更小（后向：0.1 - 0.2mm，前向：0.2 - 0.3mm）。
经过最少培训的物理治疗师在测量盂肱关节平移方面是可靠的。超声方法对于盂肱关节前向和后向平移的重复测量是可靠的，后向测量比前向测量更可靠。推荐该方法用于未来研究肩袖肌肉的稳定作用。
