| 目的 探索剪切波速度（shear wave velocity, SWV）提高肌筋膜疼痛综合征（myofascial pain syndrome, MPS）患者治疗疗效的价值。方法 选择我院收治的MPS患者80例并定义为MPS组，同期选择健康志愿者80例作为对照组。采用视觉模拟评分(visual analogue scale, VAS)、疼痛评定指数(values of pain rating index, PRI)、现时疼痛强度 (present pain intensity, PPI)评估患者疼痛程度。使用声辐射力脉冲（acoustic radiation force impulse, ARFI）弹性成像观察斜方肌组织弹性并记录SWV值。MPS患者均接受6个疗程的常规治疗，之后将疗效达到显效及以上的患者根据患者自愿原则进行分组，继续以SWV作为疗效观察指标并进行治疗的定义为继续治疗组，不继续治疗的患者定义为停止治疗组。所有患者进行为期1年的随访，比较继续治疗组与停止治疗组治疗后复发率的差异。结果 治疗过程中患者VAS值和SWV值均呈下降趋势，其差异有统计学意义（FVAS=3.649，PVAS=0.000；FVAS=2.631，PVAS=0.018）。MPS患者整体治疗的显效率为78.8%。治疗后MPS患者的VAS 、PRI、PPI均显著低于治疗前，差异均具有统计学意义（均P＜0.05）。MPS组治疗后平均SWV（2.63±1.09 m/）显著低于治疗前（4.35±1.56 m/s），差异具有统计学意义（t=8.084，P=0.000）。继续治疗组累计无复发率（93.33%）显著高于停止治疗组（61.29%），Logrank检验差异有统计学意义（X2=8.760，P=0.003）。结论 ARFI的SWV值可以客观反应MPS患者病情的严重程度，利用SWV值作为疗效的判定标准可能可以获得更好的疗效。 |

| Abstract: |
| Objective To explore the value of shear wave velocity (SWV) in improving the therapeutic effect of myofascial pain syndrome (MPS) patients. Methods Eighty patients with MPS admitted to our hospital were enrolled and defined as MPS group. Eighty healthy volunteers were enrolled as control group. The pain degree was assessed by visual analogue scale (VAS), values of pain rating index (PRI), and present pain intensity (PPI). The rectus muscle tissue elasticity was observed using acoustic radiation force impulse (ARFI) elastography and their SWV values were recorded. Patients with MPS received 6 courses of conventional treatment. Then Patients with effective effects and above were grouped according to the patient''s voluntary principle. Patients who continued to be treated using SWV as a therapeutic indicator were defined as a treatment group. Patients who stop treatment were defined as a cessation treatment group. All patients underwent a one-year follow-up. The difference in recurrence rate between the continuing treatment group and the cessation treatment group was compared. Results The VAS value and SWV value of the patients showed a downward trend during the treatment, and the differences were statistically significant (FVAS=3.649, PVAS=0.000; FVAS=2.631, PVAS=0.018). The overall efficiency of MPS patients was 78.8%. The VAS, PRI and PPI of patients with MPS after treatment were significantly lower than those before treatment, and the differences were statistically significant (P<0.05). The mean SWV (2.63±1.09 m/) after treatment in the MPS group was significantly lower than that before treatment (4.35±1.56 m/s), and the difference was statistically significant (t=8.084, P=0.000). The cumulative recurrence-free rate in the continuing treatment group (93.33%) was significantly higher than that in the cessation treatment group (61.29%), and the Logrank test was statistically significant (X2=8.760, P=0.003). Conclusion The SWV value of ARFI can objectively reflect the severity of the disease in patients with MPS. It may be possible to obtain better results by using SWV as the criterion for efficacy. |
