摘要
目的探讨超声E成像技术在颈部肌筋膜疼痛综合征治疗中的价值。方法选取符合颈部肌筋膜疼痛综合征诊断标准的患者30例,共50个肌筋膜触发点(MTrPs)。采用高频超声及超声E成像技术扫查并定位MTrPs,观察二维超声表现,测量其治疗前后MTrPs大小及杨氏模量值。结果颈部MTrPs的二维超声主要表现为肌束膜回声模糊呈高回声(96%),少数呈低回声(4%)。治疗前、首次治疗后及治疗结束时3个时间节点MTrPs大小、杨氏模量值比较差异有统计学意义(P<0.01)。治疗过程中,MTrPs大小和杨氏模量值均呈下降趋势(P<0.01),两两时点比较差异均有统计学意义(P<0.01)。结论超声E成像能清楚显示MTrPs的大小,定量杨氏模量值,为临床的治疗提供了客观影像学证据。
Objective To investigate the value of ultrasound E imaging technique in cervical myofascial pain syndrome.Methods Thirty patients meeting the diagnostic criteria of neck myofascial pain syndrome were selected,including 50 myofascial trigger points(MTrPs).The high-frequency ultrasound and ultrasound E imaging technique were used to scan and locate MTrPs.The two-dimensional ultrasound manifestations were observed,the MTrPs size and Young’s modulus value before treatment and after treatment were measured.Results The neck MTrPs two-dimensional ultrasound were mainly manifested as perimysium echo blur with high echo(96%),a few showed low echo(4%).The difference of MTrPs size before treatment,after the first treatment and at the treatment end had statistical difference among the 3 time nodes(P<0.01).During the treatment,both the size of MTrPs and Young’s modulus value showed a decreasing trend.The difference between the two time points was statistically significant(P<0.01).Conclusion The ultrasound E imaging could clearly display the size of MTrPs,quantify the Young’s modulus value to provide the objective imaging evidence for clinical treatment.
