本研究的目的是通过比较超声(US)和直接解剖测量的结果，比较股二头肌(BFlh)和半腱肌(ST)长头肌的结构参数。对3具男性身体的6条腿的BFlh和ST构筑进行了双侧观察。通过直接测量和超声扫描获得肌束长度、羽状角、肌肉厚度、肌肉和肌腱长度。两种方法的组内相关系数分别为0.905~0.913(Bflh变量)和0.774~0.974(ST参数)。与直接测量相比，US方法测量肌肉厚度的平均典型误差为0.09~0.14 cm，羽状角的平均典型误差为1.01~1.31°，束长和肌腱长度的平均典型误差为0.92~1.71 cm。US方法是评估腿肌ST和BFlh成分的基本结构参数的有效替代工具。(C)2009爱思唯尔有限公司。保留所有权利。
The purpose of this study was to compare the architectural parameters of the long head of biceps femoris (BFlh) and semitendinosus (ST) muscles by comparing measurements from ultrasound (US) with those obtained from direct dissection. The BFlh and ST architectures were examined bilaterally in 6 legs from 3 male cadavers. The fascicle length, pennation angle, muscle thickness and muscle and tendon length were obtained from direct measurement and US scans along each muscle. Intraclass correlation coefficients between the two methods ranged from 0.905 to 0.913 for the BFlh variables and from 0.774 to 0.974 for the ST parameters. Compared with the direct measurements, the US method showed a mean typical error of 0.09-0.14 cm for muscle thickness, 1.01-1.31 degrees for the pennation angle, 0.92-1.71 cm for fascicle length and muscle-tendon length measurements. The US method is a valid alternative tool for assessing basic architectural parameters of ST and BFlh components of the hamstring muscles. (C) 2009 Elsevier Ltd. All rights reserved.
