The purpose of this study was to determine the reliability and validity of ultrasonography for measurement of hamstring muscle and semitendinosus (ST) tendon cross-sectional area (CSA). On two consecutive days, muscle anatomical CSA (ACSA) and ST tendon CSA were measured at standardized positions (30%-80% of thigh length; half the distance from the distal muscle-tendon junction to the popliteal crease) on 12 legs using ultrasonography and compared with corresponding magnetic resonance imaging measures. Inter-day intraclass correlation coefficients were good-to-excellent (0.882-0.996) for all assessed muscle and tendon sites. The limits of agreement widths were narrowest (range: 17%-52%) when muscle ACSA was large but were wide at sites with relatively small ACSA (≤184%) and for ST tendon CSA (range: 72%). Results suggest ultrasound-based measures of individual hamstring muscle maximal ACSA are reliable and valid and ST tendon CSA measures are reliable but require comparison with cadaveric or intra-operative measurements to verify validity.
本研究旨在确定超声测量腘绳肌和半腱肌（ST）肌腱横截面积（CSA）的可靠性和有效性。在两天内，使用超声在标准化位置（大腿长度的 30%-80%；从肌肉-肌腱交界处到腘窝褶皱的一半距离）测量了 12 条腿的肌肉解剖 CSA（ACSA）和 ST 肌腱 CSA，并与相应的磁共振成像测量值进行了比较。所有评估的肌肉和肌腱部位的日内组内相关系数均为良好到优秀（0.882-0.996）。当肌肉 ACSA 较大时，协议界限的宽度最窄（范围：17%-52%），但在 ACSA 相对较小（≤184%）的部位和 ST 肌腱 CSA（范围：72%）的部位较宽。结果表明，基于超声的个体腘绳肌最大 ACSA 测量值具有可靠性和有效性，而 ST 肌腱 CSA 测量值具有可靠性，但需要与尸体或术中测量值进行比较以验证有效性。
