We aim to evaluate the shear wave velocity (SWV) of the thenar muscle as an adjunct diagnostic tool for carpal tunnel syndrome (CTS).
Ninety-two wrists with CTS and 30 control wrists without CTS underwent ultrasonographic evaluation of thenar muscle and median nerve including shear-wave elastography. Cross sectional area (CSA) of medial nerve and SWV of thenar muscle and median nerve were evaluated. CTS patients were assessed for Boston CTS, Padua CTS, modified Hirani grading scores, and nerve conduction study (NCS). SWVs, CSA, and NCS parameters were compared between two groups.
The SWVs of thenar muscle and median nerve (p < 0.001, respectively), and CSA of median nerve (p < 0.001) were more significantly greater in patients with CTS than in controls. The SWV of median nerve was moderately correlated with CSA of median nerve (r = 0.35, p < 0.001) and modified Hirani CTS score (r = 0.35, p < 0.001). The SWV of thenar muscle was inversely correlated with modified Hirani CTS score (r = -0.21, p = 0.04).
The SWV of thenar muscle and median nerve of CTS were significantly increased compared to that of control, and significantly negatively correlated with NCS parameters (modified Hirani CTS score). SWVs may be used as an adjunct diagnostic tool for CTS.
我们旨在评估大鱼际肌的剪切波速度（SWV）作为诊断腕管综合征（CTS）的辅助工具。
92 例 CTS 手腕和 30 例无 CTS 的对照组手腕接受了大鱼际肌和正中神经的超声评估，包括剪切波弹性成像。评估正中神经的横截面积（CSA）和大鱼际肌和正中神经的 SWV。对 CTS 患者进行波士顿 CTS、帕多瓦 CTS、改良 Hirani 分级评分和神经传导研究（NCS）评估。比较两组的 SWV、CSA 和 NCS 参数。
CTS 患者的大鱼际肌和正中神经的 SWV（分别为 p < 0.001）以及正中神经的 CSA（p < 0.001）均显著大于对照组。正中神经的 SWV与正中神经的 CSA（r = 0.35，p < 0.001）和改良 Hirani CTS 评分（r = 0.35，p < 0.001）呈中度相关。大鱼际肌的 SWV与改良 Hirani CTS 评分呈负相关（r = -0.21，p = 0.04）。
与对照组相比，CTS 患者的大鱼际肌和正中神经的 SWV 明显升高，与 NCS 参数（改良 Hirani CTS 评分）呈显著负相关。SWV 可作为 CTS 的辅助诊断工具。
