摘　　要：目的探讨剪切波弹性成像(SWE)在脑卒中下肢痉挛患者小腿三头肌(Calf triceps)硬度评估的可行性。方法选取在我院康复治疗的37例脑卒中小腿痉挛偏瘫患者为观察组,30例健康志愿者为正常组,利用高频超声及SWE技术分别测量观察组健、患两侧及正常组右侧小腿三头肌:腓肠肌内侧头(MG)、外侧头(TG)及比目鱼肌(S)厚度及杨氏模量最大值(Emax),对结果进行比较分析。结果观察组患侧小腿三头肌(MG、LG、S)弹性值均大于观察组健侧及正常组右侧,差异有统计学意义(P<0.001);观察组患侧MG、LG、S厚度均小于观察组健侧及正常组右侧,差异有统计学意义(P<0.05)。观察组健患两侧MG、LG、S厚度与弹性值之间无明显相关性(均P>0.05)。结论SWE技术能够定量测量脑卒中后下肢痉挛患者小腿三头肌的硬度,为评估脑卒中后小腿三头肌肌张力提供一种新的量化依据。Objective To explore the feasibility of shear wave elastography(SWE)in assessing the stiffness of calf triceps in patients with lower extremity spasm after stroke.Methods We selected 37 patients with stroke,calf spasm and hemiplegia treated in our hospital as the observation group,30 healthy volunteers as the normal group,and used high-frequency ultrasound and SWE technology to measure the two sides of the observation group and the right calf of the normal group.Head muscles included the thickness of the medial head(MG),lateral head(TG)and soleus(S)of the gastrocnemius muscle and the maximum Young's modulus(Emax).The results were compared and analyzed.Results The elastic values of the triceps muscles(MG,LG,S)of the affected side of the observation group were greater than those of the healthy side of the observation group and the right side of the normal group,and the difference was statistically significant(P<0.001);The thickness was smaller than the healthy side of the observation group and the right side of the normal group,and the difference was statistically significant(P<0.05).There was no significant correlation between the thickness of MG,LG,S on both sides of the patients in the observation group and the elasticity value(all P>0.05).The elastic values of the triceps(MG,LG,S)of the affected side of the observation group were greater than those of the healthy side of the observation group and the right side of the normal group,and the difference was statistically significant(P<0.001);the thickness of MG,LG,S of the affected side of the observation group both were smaller than the healthy side of the observation group and the right side of the normal group,the difference was statistically significant(P<0.05).There was no significant correlation between the thickness of MG,LG,S on both sides of the patients in the observation group and the elasticity value(all P>0.05).Conclusion We can quantitatively measure the stiffness of calf triceps in patients with lower extremity spasm after stroke,providing a new quan
