Abstract：
BACKGROUND: The objective of this investigation is to evaluate the consistency of intra-rater and inter-rater assessments utilizing ultrasound elastography to examine the muscle stiffness of the popliteus and gastrocnemius (medial and lateral heads) in patients with knee osteoarthritis accompanied by myofascial trigger points.
METHODS: Thirty individuals with knee osteoarthritis accompanied by myofascial trigger points were assessed. Two examiners independently measured the muscle stiffness levels of the popliteus and gastrocnemius (medial and lateral heads) three times using ultrasound elastography in the first session. The second session was conducted one week later.
RESULTS: In the initial test session, the mean shear modulus values for the popliteus and gastrocnemius (medial and lateral heads) muscles were measured as follows for tester 1 (12.75, 13.72, 14.13 kPa) and tester 2 (11.66, 12.81, 13.17 kPa). During the retest session, the previously measured variables by tester 1 and tester 2 yielded the following values: (12.61, 13.43, 14.26 kPa) and (11.62, 12.87, 13.30 kPa) respectively.\" Good to excellent intra-rater reliability (ICC = 0.912-0.986) and inter-rater reliability (ICC = 0.766-0.956) were reported for the shear moduli of the popliteus, medial and lateral gastrocnemius muscles.
CONCLUSIONS: The assessment of muscle stiffness in the popliteus and gastrocnemius (medial and lateral heads) using ultrasound elastography is a reliable method in patients with knee osteoarthritis accompanied by myofascial trigger points.

摘要：
背景：本研究的目的是评估评估者内部和评估者之间评估的一致性，利用超声弹性成像检查伴有肌筋膜触发点的膝骨关节炎患者的po和腓肠肌（内侧和外侧头）的肌肉硬度。
方法：对30例伴有肌筋膜触发点的膝骨关节炎患者进行评估。在第一个疗程中，两名检查者使用超声弹性成像技术独立地测量了the肌和腓肠肌（内侧和外侧头）的肌肉硬度水平。第二届会议在一周后举行。
结果：在初始测试会话中，对于测试仪1（12.75,13.72,14.13kPa）和测试仪2（11.66,12.81,13.17kPa），测量了the肌和腓肠肌（内侧和外侧头）的平均剪切模量值。在复试期间,测试器1和测试器2先前测量的变量分别得到以下值:(12.61,13.43,14.26kPa)和(11.62,12.87,13.30kPa)。\“良好到出色的评分者内部可靠性（ICC=0.912-0.986）和评分者之间的可靠性（ICC=0.766-0.956）据报道，内侧和外侧腓肠肌。
结论：在伴有肌筋膜触发点的膝骨关节炎患者中，使用超声弹性成像技术评估pop和腓肠肌（内侧和外侧头）的肌肉硬度是一种可靠的方法。
