| 目的 探讨灰阶超声联合剪切波弹性成像（SWE）技术评估肌筋膜疼痛综合征（MPS）患者肌筋膜疼痛触发点（MTrPs）处肌肉形态及组织学特性的价值。方法 以28例MPS患者（36个MTrPs）为病例组，33名健康志愿者（33个正常肌肉点）为对照组。由2名检查者分别测量病例组MTrPs （上斜方肌）厚度、剪切波传播速度（SWV）及杨氏模量值（E），1名检查者测量对照组上述参数，1周后2组均重复测量。采用组内相关系数（ICC）评价2名检查者检测结果的一致性，以Pearson检验分析MPS患者疼痛视觉模拟量表（VAS）评分与上斜方肌厚度、SWV及E的相关性。结果 2名检查者重复测量一致性、时间一致性及检查者间一致性均好或优（ICC 0.73~0.98）。病例组MPS患者上斜方肌厚度、SWV及E均高于对照组，差异均有统计学意义（P均<0.05）。MPS患者VAS评分与上斜方肌厚度无相关性（r=0.016，P=0.945），与SWV （r=0.709，P<0.001）、E （r=0.653，P=0.002）均呈正相关。结论 灰阶超声联合SWE可定量评估MPS患者MTrPs处肌肉形态及组织学特性。 |

| Objective To explore the application value of gray scale ultrasound combined with shear wave elastography(SWE) in evaluation of myofascial trigger points (MTrPs) in patients with myofascial pain syndrome (MPS). Methods Totally 28 MPS patients (case group, 36 MTrPs) and 33 healthy volunteers (control group, 33 normal muscle points) were enrolled. In case group, 2 examiners measured the muscle thickness of superior trapezius, shear wave velocity (SWV) and Young's modulus (E), while only one examiner measured the above indexes in control group. One week later, the measurements were repeated in both groups. The consistency between 2 examiners was evaluated by using intra-class correlation coefficient (ICC). Pearson correlation analysis was used to evaluate the correlation of visual analogue scale(VAS) in MPS patients with the muscle thickness of superior trapezius, SWV and E. Results The consistency of repeated measurement, consistency of time and consistency between 2 examiners were all good or excellent (ICC 0.73-0.98). The muscle thickness of superior trapezius, SWV and E in case group were higher than those in control group (all P<0.05). There was no correlation between VAS and muscle thickness, but positive correlations between VAS and SWV (r=0.709, P<0.001), E (r=0.653, P=0.002). Conclusion Gray scale ultrasound combined with SWE can be used to assess the morphological features and biomechanical property of MTrPs in patients with MPS. |
