Sono-myography and sono-myoelastography have been found useful in the investigation of myofascial trigger points. The objective of this study was to use the same techniques to investigate the morphology, stiffness and blood flow of tender points in women with fibromyalgia and to compare the results with those for samples from healthy patients. Algometry tests indicated significant differences between groups (p < 0.001). Elliptical and hypoechoic areas were observed in the ultrasound images of the upper trapezius in both groups. No differences between groups were found in the number of hypoechoic areas (p = 0.167, t = 1.008); blood flow also did not differ between the groups. Larger hypoechoic areas were found in the fibromyalgia group (p = 0.139, t = 1.317). Sono-myoelastography did not reveal greater stiffness in these areas compared with the rest of the muscle. These results lead us to believe that sono-myoelastography and sono-myography, used in the diagnosis of myofascial trigger points, may not be able to discriminate tender points.
肌声图和肌声弹性成像已被证明在肌筋膜触发点的研究中非常有用。本研究的目的是使用相同的技术来研究纤维肌痛女性的痛点的形态、硬度和血流，并将结果与健康患者的样本进行比较。压痛计测试表明组间存在显著差异（p<0.001）。在两组的上斜方肌的超声图像中均观察到椭圆形和低回声区。两组间低回声区的数量无差异（p=0.167，t=1.008）；血流也没有差异。在纤维肌痛组中发现更大的低回声区（p=0.139，t=1.317）。与肌肉的其他部位相比，在这些区域未发现肌声弹性成像显示出更大的硬度。这些结果使我们相信，用于肌筋膜触发点诊断的肌声图和肌声弹性成像可能无法区分痛点。
