BACKGROUND
Ultrasound imaging is important in many fields such as medicine, sports, and health sciences to assess parts of muscle structure (e.g., muscle thickness [MT]) or composition (subcutaneous tissue [Sub]).
OBJECTIVE
The aim of the present study was to investigate the intra- and inter-rater reliability of MT and Sub measurements of the hip abductor muscles gluteus medius (GM) and tensor fascia latae (TFL).
DESIGN
Cross-sectional study.
METHOD
Twenty young adults participated in the study. Intra-rater reliability was established by measuring the same two images twice by the same rater, while inter-rater reliability was assessed between two raters by measuring the same two images for each muscle. For both intra- and inter-rater reliability, the reliability of the TFL and GM outcomes (MT- Sub) were determined by the intraclass correlation coefficient (ICC), coefficient of variation (CV), standard error of the measurement (SEM), and Bland-Altman plots.
RESULTS
For intra-rater reliability, variables of both muscles showed an excellent ICC (≥0.90), lower CV and SEM, and bias near zero. Inter-rater reliability also showed an excellent ICC for both variables and muscles (≥0.81) with lower CV, SEM, and bias.
CONCLUSION
Therefore, these results provide strong evidence of a reliable measure of MT and Sub from GM and TFL. The present study provides health care professionals and researchers increased confidence in using 2D ultrasound to assess the hip abductors muscles reliably.
背景
超声成像是医学、运动和健康科学等领域中评估肌肉结构（例如肌肉厚度[MT]）或组成（皮下组织[Sub]）的重要手段。
目的
本研究旨在探讨髋关节外展肌臀中肌（GM）和阔筋膜张肌（TFL）的 MT 和 Sub 测量的组内和组间可靠性。
设计
横断面研究。
方法
20 名年轻成年人参加了这项研究。组内可靠性通过同一位评估者两次测量同两张图像来确定，而组间可靠性则通过两位评估者测量每个肌肉的同两张图像来评估。对于组内和组间可靠性，通过组内相关系数（ICC）、变异系数（CV）、测量标准误差（SEM）和 Bland-Altman 图来确定 TFL 和 GM 结果（MT-Sub）的可靠性。
结果
对于组内可靠性，两种肌肉的变量均表现出极好的 ICC（≥0.90）、较低的 CV 和 SEM，以及接近零的偏差。两种变量和肌肉的组间可靠性也表现出极好的 ICC（≥0.81），同时具有较低的 CV、SEM 和偏差。
结论
因此，这些结果为 GM 和 TFL 的 MT 和 Sub 的可靠测量提供了有力证据。本研究为医疗保健专业人员和研究人员提供了使用 2D 超声可靠评估髋关节外展肌的信心。
