Abstract:
Objective To observe the value of shear wave elastography(SWE)for evaluating therapeutic effect of ultrasound-guided drug injection for muscle injury.Methods Eighty patients with unilateral muscle injury were retrospectively included,including 40 cases underwent ultrasound-guided drug injection(group A)and 40 cases underwent electromagnetic wave physiotherapy plus external application of Yunnan Baiyao Gao(group B).Pain intensity was assessed using visual analogue scale(VAS)before treatment and 3 weeks after the final treatment,while the Young modulus(E)value of the injured muscle was measured before treatment and 1,2 and 3 weeks after final treatment,and the improvements of VAS scores and E values were compared between groups.Results The total effective rate in group A(35/40,87.50%)was higher than that in group B(21/40,52.50%;P＜0.05).Before treatment,no significant difference of VAS score was found between group A(8.07±0.83)and group B(7.88±0.85)(P＞0.05).After treatment,VAS scores decreased in both groups(both P＜0.05),which in group A(2.30±1.07)was more obviously than that in group B(4.80±0.82)(P＜0.05).After treatment,E values of injury muscles increased significantly in both groups(P＜0.05),while group A had a greater increase in overall magnitude and overall rate than group B(P＜0.05).Conclusion Ultrasound-guided drug injection therapy had significant therapeutic effect for muscle injuries,which could be dynamically monitored with SWE.
