概括
超声波切割波速度 (SWV) 可能有助于评估平脚的支结构. 较低的SWV在症状平脚表明退行性变化,但需要更多的研究临床使用.
科学领域:
- 生物力学和肌肉骨成像技术
- 足部和脚骨科 足部和脚骨科
背景情况:
- 渐进式倒塌脚形经常涉及后肌 (PTT),骨肌和弹带问题.
- 了解这些结构的机械特性对于管理足部形至关重要.
研究的目的:
- 在关键支结构中测量超声波剪切波速度 (SWV).
- 为了将SWV与不同程度的脚变形相关联.
主要方法:
- 在中性,无症状的平脚和有症状的平脚中,对PTT,甲状腺和弹带进行了SWV测量.
- 测量是在不同的方向进行的,并应用了恒定应力.
主要成果:
- 与正常脚相比,有症状的平脚在内状PTT和弹带中显示出较低的平均SWV.
- 逆转应力增加了带SWV,但降低了顶PTTSWV.
- 在短轴上,PTT SWV比长轴更低.
结论:
- SWV显示了评估脚结构退行性变化的潜力.
- 需要进一步的研究来确定SWV测量的临床适用性.

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.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
2
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
