Abstract

OBJECTIVE

To use probe oscillation shear wave elastography (PROSE) with two vibration sources to generate two shear waves in the imaging plane to quantitatively assess the shear wave speeds (SWSs) of muscles with and without the diagnosis of taut bands (TB) and/or myofascial trigger points (MTrPs).

METHODS

Thirty-three patients were scanned with the PROSE technique. Shear waves were generated through continuous vibration of the ultrasound probe, while the shear wave motions were detected using the same probe. SWSs for the sides with and without TBs and/or MTrPs were computed and compared. The pressure pain thresholds (PPTs) were measured as an indicator of maximum pain tolerance of patients. The statistical differences between the SWSs with and without TBs and/or MTrPs with different PPT values were analyzed using the nonparametric Wilcoxon rank-sum test.

RESULTS

The mean SWSs for the sides with TBs and/or MTrPs are faster than that of the contralateral side without TBs and/or MTrPs. A significant difference was observed between mean SWSs with and without TBs and/or MTrPs without any information of PPT, with rank-sum test P <  .005. Additionally, with the information of PPT, a significant difference was observed between mean SWSs for the sides with and without TBs and/or MTrPs, for PPT values between 0 and 50 N/cm (P <  .005), but for PPT values between 50 and 90 N/cm , it was difficult to differentiate mean SWSs with and without TBs and/or MTrPs.

CONCLUSION

Our preliminary results show that SWSs measured from patients had a significant difference between the mean SWSs with and without TBs and/or MTrPs.

摘要

目的

使用具有两个振动源的探头振荡剪切波弹性成像（PROSE）在成像平面中产生两个剪切波，以定量评估有和无紧绷带（TB）和/或肌筋膜触发点（MTrP）诊断的肌肉的剪切波速度（SWS）。

方法

使用 PROSE 技术对 33 名患者进行扫描。通过连续振动超声探头产生剪切波，同时使用相同的探头检测剪切波运动。计算并比较有和无 TB 和/或 MTrP 的两侧的 SWS。压力疼痛阈值（PPT）被测量为患者最大疼痛耐受度的指标。使用非参数 Wilcoxon 秩和检验分析具有不同 PPT 值的具有和不具有 TB 和/或 MTrP 的 SWS 之间的统计差异。

结果

有 TB 和/或 MTrP 的侧的平均 SWS 比没有 TB 和/或 MTrP 的对侧快。在没有任何 PPT 信息的情况下，具有和不具有 TB 和/或 MTrP 的平均 SWS 之间存在显著差异，秩和检验 P < 0.005。此外，根据 PPT 的信息，在 PPT 值在 0 到 50 N/cm 之间时，有和无 TB 和/或 MTrP 的侧的平均 SWS 之间存在显著差异（P < 0.005），但在 PPT 值在 50 到 90 N/cm 之间时，很难区分有和无 TB 和/或 MTrP 的侧的平均 SWS。

结论

我们的初步结果表明，从患者测量的 SWS 在有和无 TB 和/或 MTrP 的情况下存在显著差异。
