科学领域:

  • 肌肉骨超声波 肌肉骨超声波
  • 生物力学 生物力学
  • 医疗成像医学成像

背景情况:

  • 对于临床应用来说,深宫肌肉机制的可重复性评估至关重要.
  • 剪切波弹性图 (SWE) 对长肌 (LC) 的可靠性尚未先前确立.
  • 机械部疼痛需要可靠的方法来评估肌肉功能.

研究的目的:

  • 通过使用SWE来确定LC度测量的内部和内部检查员的可靠性.
  • 确定SWE的可重现性,用于评估LC肌肉的机械性质.
  • 为了验证一个标准化的SWE协议,用于患有机械部疼痛的患者.

主要方法:

  • 一项纵向可靠性研究,涉及慢性部疼痛 (≥6个月) 的成年人.
  • 两位不同经验的检查员使用标准化的SWE预设进行了双边LC成像.
  • 获得了剪波速度和扬模量的测量,使用类内相关系数 (ICC) 评估了可靠性.

主要成果:

  • 对于单个 (ICC3,2>0.818) 和平均 (ICC3,2>0.866) 的LC刚度测量,观察到良好的至优秀的检查员间一致性.
  • 对于新手考官来说,考官内部的可重复性很好或很好 (ICC3,1>0.891),对于经验丰富的考官来说,可重复性很好 (ICC3,1>0.973).
  • 根据性别或测量侧面 (p > 0.05) 发现硬度没有显著差异.

结论:

  • 一个标准化的SWE工作流程可以在机械部疼痛患者中可重复测量LC度.
  • 对于纵向研究,建议保持单个操作员.
  • 在多检查者设置中,平均每侧至少两次采集可以提高检测LC刚性的真实变化的灵敏度.
