概括
这项研究发现,便携式超声波设备为内在和外在足部肌肉提供中等到优异的测试-重新测试可靠性. 然而,评估者之间的可靠性有所不同,这凸显了在临床和研究环境中需要一致的图像采集协议的需要.
科学领域:
- 生物力学 生物力学
- 医疗成像医学成像
- 肌肉骨超声波 肌肉骨超声波
背景情况:
- 定量超声波成像对于评估脚肌肉结构至关重要.
- 现有的研究在评级者之间的可靠性方面存在差距,特别是在图像采集与测量方面.
- 之前的研究经常使用非通用化的设备,并且缺乏可靠的样本大小计算.
研究的目的:
- 用低成本的超声波设备评估内在和外在足部肌肉测量的测试-重新测试可靠性.
- 评估这些肌肉的全球和基于测量的评分器间可靠性 (MIRR).
- 确定便携式超声波在临床和研究应用中的通用性.
主要方法:
- 一项涉及21名活跃个体的前性可靠性研究.
- 五个内在和三个外在足部肌肉的超声波成像 (例如,绑架者幻觉,前脚).
- 三名独立调查人员在两个不同的场合获得了图像,并测量了截面积 (CSA) 和厚度,通过ICC,SEM和CV进行分析.
主要成果:
- 试验复试可靠性显示ICCs在0.38-0.88之间,SEM用于内在肌肉 (CSA:0.16-0.41厘米,厚度:0.05-0.31厘米) 和外在肌肉 (CSA:0.19-1.13厘米,厚度:0.12-0.44厘米).
- 全球级别之间的可靠性有所不同 (ICCs 0.4-0.8),而MIRR显示特定肌肉的系数较高 (0.50-0.96).
- 变化系数在4%至34%之间,在测试复试场景中,Abductor Hallucis厚度,Flexor Digitorum Brevis CSA,Flexor Hallucis Brevis和Tibialis Anterior的变化系数为<10%.
结论:
- 便携式超声波设备对脚肌肉的测试-重新测试可靠性中等至优异,支持在各种环境中使用它们.
- 全球评分器间可靠性的显著变化表明在图像采集过程中存在潜在问题.
- 建议采用标准化的图像采集和持续的临床医生参与,以尽量减少测量错误并确保可靠的比较.

Muscles of the Leg that Move the Foot and Toes
1.2K
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles....

Ultrasonography
4.3K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
