摘要:

目的 探讨多模态超声成像在量化评估脑卒中偏瘫患者肌肉痉挛中的应用。

方法 2019年3月至9月,本院脑卒中下肢偏瘫患者44例为试验组,同期健康体检者46例为对照组,对试验组健侧、患侧及对照组右侧腓肠肌内侧头同一位置行二维灰阶超声、剪切波弹性成像和超微血管成像超声检查,记录剪切波速度(SWV)、血流信号值、羽状角(PA)、肌肉厚度(MT)、肌纤维长度(FL)。

结果 试验组患侧SWV明显高于健侧和对照组(t > 6.346, P < 0.01)。静息状态下,试验组患侧FL较健侧和对照组明显缩短(|t| > 6.235, P < 0.01),MT和PA与健侧有显著性差异(|t| > 2.198, P < 0.05);血流信号值低于对照组(t = 2.604, P < 0.05);最大等长收缩状态下,FL缩短较健侧和对照组显著减小(Z > 6.703, P < 0.001)。

结论 超声成像技术能从肌肉结构、血流和硬度等方面定量评价脑卒中患者腓肠肌变化,可为痉挛的诊断和随访提供客观资料。

Abstract:

Objective To apply multimodal ultrasound imaging in spasticity assessment for stroke patients with hemiplegia.

Methods From March to September, 2019, 44 inpatients with lower limb spastic hemiplegia after stroke (patients) and 46 healthy volunteers (controls) were scanned with two-dimensional ultrasound imaging, shear wave elastography and super microvascular imaging at the same area of gastrocnemius muscle of both sides of patients and right side of controls, in resting and maximum isometric contraction. The parameters of shear wave velocity (SWV), blood flow signal, pinnation angle (PA), fascicle length (FL) and muscle thickness (MT) were recorded.

Results SWV increased in the affected side of the patients compared with those of the unaffected side and controls in resting (t > 6.346, P < 0.01), while FL shortened (|t| > 6.235, P < 0.01), MT and PA changed compared with those of the unaffected side (|t| > 2.198, P < 0.05), and blood flow signal decreased compared with those of the controls (t = 2.604, P < 0.05). In maximum isometric contraction, the decrease of FL was less compared with those of the unaffected side and controls (Z > 6.703, P < 0.001).

Conclusion Ultrasound imaging can quantitatively evaluate spasticity of gastrocnemius muscle for patients with stroke in terms of morphological structure, blood flow, and muscle stiffness.
