概括

超声波弹性图揭示了局部梯形肌硬度与横向宫动脉血流相关. 在TCA中较低的血流速度与部和上背部硬症状的增加有关.

科学领域:

生物医学工程生物医学工程
肌肉骨超声波肌肉骨超声波
血管生理学血管生理学

背景情况:

子和上背部的硬,通常感觉到形肌 (TM) 沉或疼痛,是一种常见的投诉.
之前的研究将TM硬度 (用肌肉硬度计测量) 与横向宫动脉 (TCA) 血流联系起来.
以往方法的局限性使得需要使用先进技术来评估局部TM硬度.

研究的目的:

通过超声波弹性学评估的局部TM硬度与TCA血液动力学之间的关系.
为了将这些发现与每日部和上背部硬症状的频率相关联.

主要方法:

66名健康的年轻成年人 (32名男性,34名女性;平均年龄21岁) 参加了这项研究.
超声波弹性学测量了TM硬度 (通过应变比),多普勒声学评估了TCA血液动力学.
统计分析检查了TM硬度,TCA血流 (峰值缩速度-PSV) 和症状频率之间的相关性.

主要成果:

在TM应变比和TCA峰值心缩速度 (PSV) (r=0.273,p=0.036) 之间发现了显著的相关性.
这种相关性在经历硬度症状的受试者中更强 (r=0.417,p=0.022).
在TCA中,随着每日硬症状的频率增加,PSV显著下降 (p=0.045).

结论:

局部的TM硬度,通过弹性学测量,与TCA功能血动学相关.
在患有更频繁部和上背部硬的个体中观察到减少TCA PSV.
TCA 血液动力学,特别是PSV,可以作为部和上背部硬的潜在指标.

Autoregulation of Blood Flow

Autoregulation of Blood Flow

Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation....

Navier–Stokes Equations

Navier–Stokes Equations

For incompressible Newtonian fluids, where density remains constant, stresses show a linear relationship with the deformation rate, defined by normal and shear stresses. Normal stresses depend on the pressure exerted on the fluid and the rate of deformation in specific directions, which determines how fluid flows under varying pressures. Shear stresses, on the other hand, act tangentially across fluid layers. They explain how adjacent fluid layers slide relative to one another, connecting...
