本申请实施例公开了一种肌张力评估方法，包括：获取被测骨骼肌在不同关节角度下的弹性模量值；根据所述被测骨骼肌在不同关节角度下的弹性模量值及各个所述关节角度，确定所述被测骨骼肌的弹性模量的变化趋势；根据所述被测骨骼肌的弹性模量的变化趋势，对所述被测骨骼肌的肌张力进行级别评估。在本申请中，可以实现对肌张力的评估。
接下来对本申请实施例公开的肌张力评估方法进行介绍，请参见图1，可以包括：
步骤S11、获取被测骨骼肌在不同关节角度下的弹性模量值及各个所述关节角度。
本实施例中，由测量设备测量被测骨骼肌在不同关节角度下的弹性模量值，并将测量得到的被测骨骼肌在不同关节角度下的弹性模量值导入处理器。相应地，处理器获取测量设备导入的被测骨骼肌在不同关节角度下的弹性模量值。
本实施例中，获取被测骨骼肌在不同关节角度下的弹性模量值的过程，可以包括：
A11、获取所述被测骨骼肌在各个所述关节角度下，多次测量的弹性模量值。
A12、分别对所述被测骨骼肌在各个所述关节角度下，多次测量的弹性模量值进行平均运算，将平均运算的结果作为所述被测骨骼肌在所述关节角度下的弹性模量值。
将平均运算的结果作为被测骨骼肌在所述关节角度下的弹性模量值，可以提高弹性模量值的可靠性。
各个关节角度可以由移动臂和固定臂组成的普通量角器测量，其中，移动臂标有指针，固定臂附有刻度盘。具体地，被测骨骼肌所对应的关节自由活动或被动活动，普通量角器对被测骨骼肌所对应的关节所处的角度进行测量。测量时，移动臂和固定臂于一端以活动轴固定，如图2所示。测量得到的关节角度可以导入处理器。
优选的，测量设备可以为：超声诊断仪。
优选的，利用超声诊断仪测量被测骨骼肌在不同关节角度下的弹性模量值的过程，可以包括：
采用超声诊断仪的B-mode成像模式，检测被测骨骼肌的垂直肌束横切面，确定肌腹最厚位置，然后原位6置旋转探头，沿肌腹最厚位置的肌束方向纵切面检查骨骼肌长轴，启动弹性成像模式，固定探头位置，连续测量关节角度变 化时，被测骨骼肌的肌腹最厚位置的弹性模量值(如，杨氏模量值)，并生成动态超声弹性图像序列。
测量被测骨骼肌的肌腹最厚位置的弹性模量值时，具体可以测量被测骨骼肌的肌腹最厚位置中感兴趣区域的弹性模量值(如图3所示的矩形方框中的弹性模量值)，并将感兴趣区域的弹性模量值的平均值作为被测骨骼肌的弹性模量值。其中，感兴趣区域可以设置为10mm×10mm的矩形区域。
需要说明的是，由于肌腹最厚位置能够较为准确的反映肌张力，因此测量被测骨骼肌的肌腹最厚位置的弹性模量值，可以保证测量的结果的准确性。
更进一步的，可以对同一个感兴趣区域测量多次，并将多次的测量结果进行平均运算，平均运算的结果作为感兴趣区域的弹性模量值。
步骤S12、根据所述被测骨骼肌在不同关节角度下的弹性模量值及各个所述关节角度，确定所述被测骨骼肌的弹性模量值的变化趋势。
具体可以通过比较各个关节角度下，被测骨骼肌的弹性模量值，根据比较结果确定被测骨骼肌的弹性模量值的变化趋势。
当然，也可以采用更直观的形式，确定被测骨骼肌的弹性模量值的变化趋势。具体可以为：以各个所述关节角度为横坐标，以所述被测骨骼肌在不同关节角度下的弹性模量值为纵坐标，绘制所述被测骨骼肌的弹性模量的变化趋势曲线图。其中，变化趋势曲线图用于表征所述被测骨骼肌的弹性模量值的变化趋势，如图4(a)-(f)示出了被测骨骼肌的弹性模量值的不同变化趋势。
步骤S13、根据所述被测骨骼肌的弹性模量值的变化趋势，对所述被测骨骼肌的肌张力进行级别评估。
如图4(a)所示，若被测骨骼肌的弹性模量值的变化趋势为：在各个关节角度对应的关节活动范围内，被测骨骼肌的弹性模量值小，且平缓增大，则可以确定被测骨骼肌的肌张力为0级即肌张力低下。
如图4(b)所示，若被测骨骼肌的弹性模量值的变化趋势为：在各个关节角度对应的关节活动范围内，被测骨骼肌的弹性模量值缓慢增大，且在最大关节角度时显著增大，则可以确定被测骨骼肌的肌张力为1级即肌张力正常。
如图4(c)所示，若被测骨骼肌的弹性模量值的变化趋势为：在关节角度小于设定角度时，随着关节角度的变化，被测骨骼肌的弹性模量值变化不明显， 在关节角度大于设定角度时，随着关节角度的变化，被测骨骼肌的弹性模量值显著增大，则可以确定被测骨骼肌的肌张力为2级即肌张力轻度增加。
如图4(d)所示，若被测骨骼肌的弹性模量值的变化趋势为：随着关节角度的增大，被测骨骼肌的弹性模量值增大，并且在关节角度达到设定角度时，被测骨骼肌的弹性模量值显著增大，则可以确定被测骨骼肌的肌张力为3级即肌张力明显增加。
如图4(e)所示，若被测骨骼肌的弹性模量值的变化趋势为：关节角度变化范围缩小，并且在关节角度的变化范围内，被测骨骼肌的弹性模量值显著增大，则可以确定被测骨骼肌的肌张力为4级即肌张力严重增高。
如图4(f)所示，若被测骨骼肌的弹性模量值的变化趋势为：关节角度变化范围小即关节活动困难，并且在关节角度的变化范围内，被测骨骼肌的弹性模量值显著增大，则可以确定被测骨骼肌的肌张力为5级即肌张力僵直。
在本申请中，获取被测骨骼肌在不同关节角度下的弹性模量值，作为被测骨骼肌的肌张力的监测依据，并基于弹性模量值的变化可以表征骨骼肌活动时阻力的变化，阻力的变化又可以反映肌张力的情况的原则，根据所述被测骨骼肌在不同关节角度下的弹性模量值及各个所述关节角度，确定所述被测骨骼肌的弹性模量的变化趋势，并根据所述被测骨骼肌的弹性模量的变化趋势，对所述被测骨骼肌的肌张力进行级别评估。
对肌张力进行级别评估的评估结果，对骨骼肌系统疾病的早期诊断、病理研究和治疗评估、预后均具有重要的应用潜力。

需要说明的是，本说明书中的各个实施例均采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似的部分互相参见即可。对于装置类实施例而言，由于其与方法实施例基本相似，所以描述的比较简单，相关之处参见方法实施例的部分说明即可。
最后，还需要说明的是，在本文中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
为了描述的方便，描述以上装置时以功能分为各种单元分别描述。当然，在实施本申请时可以把各单元的功能在同一个或多个软件和/或硬件中实现。
通过以上的实施方式的描述可知，本领域的技术人员可以清楚地了解到本申请可借助软件加必需的通用硬件平台的方式来实现。基于这样的理解，本申请的技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品可以存储在存储介质中，如ROM/RAM、磁碟、光盘等，包括若干指令用以使得一台计算机设备(可以是个人计算机，服务器，或者网络设备等)执行本申请各个实施例或者实施例的某些部分所述的方法。
以上对本申请所提供的一种肌张力评估方法及装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
