Clinical study of dynamic two-dimensional shear wave elastography in quantifying hand spasm after stroke

中文摘要英文摘要

目的 研究动态二维剪切波弹性成像(2D-SWE)测量松弛角定量脑卒中患者指伸肌痉挛的可行性.方法 选取2022年3月至2023年4月该院收治的住院脑卒中后手痉挛患者30例作为研究组,选取2023年1-4月在该院体检中心进行体检的健康者30名作为对照组.应用2D-SWE测量松弛角,描记指伸肌关节角度-弹性模量曲线,评定改良阿什沃思量表(MAS),并检验松弛角与 MAS的相关性.结果 松弛角与MAS明显相关,差异有统计学意义(rs=-0.876,P<0.001);研究组患者弹性参数E0[(10.15±0.75)kPa]、指伸肌松弛角[(-26.51±4.87)°]均明显小于对照组[分别为(11.94±0.91)kPa、(-19.86±3.77)°],差异均有统计学意义(P<0.05).结论 2D-SWE测量指伸肌松弛角可定量脑卒中后手痉挛程度.

Objective To study the feasibility of dynamic two-dimensional shear wave elastography(2D-SWE)in measuring relaxation angle to quantify extensor digitorum spasm in stroke patients.Methods A total of 30 patients with hand spasm after stroke admitted to our hospital from March 2022 to April 2023 were selected as the study group,and 30 healthy people who underwent physical examination in our hospital from January to April 2023 were selected as the control group.The relaxation angle was measured by 2D-SWE,the joint angle-elastic modulus curve of extensor digitorum was recorded,the modified Ashworth scale(MAS)was evaluated,and the correlation between relaxation angle and MAS was tested.Results The relaxation an-gle was significantly correlated with MAS(rs=-0.876,P<0.001).The elastic parameters E0[(10.15±0.75)kPa]and extensor relaxation angle[(-26.51±4.87)°]in the study group were significantly lower than those in the control group[(11.94±0.91)kPa,(-19.86±3.77)°],the differences were statistically sig-nificant(P<0.05).Conclusion 2D-SWE measurement of extensor relaxation angle can quantify the degree of hand spasm after stroke.
