The validity and reliability of 3-D ultrasound (US) in estimation of muscle and tendon volume was assessed in a very limited number of muscles that can be easily immersed. The objective of the present study was to assess the validity and reliability of muscle volume measurements for all hamstring muscle heads and gracilis (GR), as well as tendon volume for the semitendinosus (ST) and GR using freehand 3-D US.
Three-dimensional US acquisitions were performed for 13 participants in two distinct sessions on separate days, in addition to one session dedicated to magnetic resonance imaging (MRI). Volumes of ST, semimembranosus (SM), biceps femoris short (BFsh) and long (BFlh) heads, and GR muscles and from the tendon from semitendinosus (STtd) and gracilis (GRtd) were collected.
The bias and the 95% confidence intervals of 3-D US compared with MRI ranged from -1.9 mL (-0.8%) to 1.2 mL (1.0%) for muscle volume and from 0.01 mL (0.2%) to -0.03 mL (-2.6%) for tendon volume. For muscle volume assessed using 3-D US, intraclass correlation coefficients (ICCs) ranged from 0.98 (GR) to 1.00, and coefficients of variation (CV) from 1.1% (SM) to 3.4% (BFsh). For tendon volume, ICCs were 0.99, and CVs between 3.2% (STtd) and 3.4% (GRtd).
Three-dimensional US can provide a valid and reliable inter-day measurement of hamstrings and GR for both muscle and tendon volumes. In the future, this technique could be used as an outcome for strengthening interventions and potentially in clinical environments.
在数量有限的可轻松浸没的肌肉中评估了 3-D 超声（US）在肌肉和肌腱体积估计中的有效性和可靠性。本研究的目的是使用自由手 3-D US 评估所有腘绳肌和股薄肌（GR）的肌肉体积测量以及半腱肌（ST）和 GR 的肌腱体积的有效性和可靠性。
在两个不同的日子里，对 13 名参与者进行了 3 次 US 采集，另外还进行了一次专门用于磁共振成像（MRI）的采集。收集了 ST、半膜肌（SM）、股二头肌短头（BFsh）和长头（BFlh）以及 GR 肌肉的体积以及来自半腱肌（STtd）和股薄肌（GRtd）的肌腱体积。
与 MRI 相比，3-D US 的偏差和 95%置信区间在肌肉体积方面为-1.9 mL（-0.8%）至 1.2 mL（1.0%），在肌腱体积方面为 0.01 mL（0.2%）至-0.03 mL（-2.6%）。使用 3-D US 评估肌肉体积时，组内相关系数（ICC）范围为 0.98（GR）至 1.00，变异系数（CV）范围为 1.1%（SM）至 3.4%（BFsh）。对于肌腱体积，ICC 为 0.99，CV 在 3.2%（STtd）和 3.4%（GRtd）之间。
3-D US 可以提供一种有效的、可靠的日内测量方法，用于测量腘绳肌和 GR 的肌肉和肌腱体积。未来，这项技术可以作为强化干预的结果，并可能在临床环境中使用。
