Motion of the median nerve was compared on an axial ultrasonographic image in the mid-carpal tunnel in 30 wrists of 15 women with bilateral idiopathic carpal tunnel syndrome and 30 wrists of 15 healthy women. During passive flexion and extension of the index finger, the control wrists had transverse sliding of the nerve beneath the flexor retinaculum (1.75 +/- 0.49 mm), which was regarded as a physiological phenomenon. In contrast, the wrists of patients with carpal tunnel syndrome had significantly less sliding (0.37 +/- 0.34 mm; P = 0.0001), which indicates that physiological motion of the nerve is restricted. This decrease in nerve mobility may be of significance in the pathophysiology of carpal tunnel syndrome.
在15名双侧特发性腕管综合征女性的30只手腕以及15名健康女性的30只手腕中，通过轴向超声图像对腕中管内正中神经的运动情况进行了比较。在食指被动屈伸过程中，对照手腕的神经在屈肌支持带下方有横向滑动（1.75±0.49毫米），这被视为一种生理现象。相比之下，腕管综合征患者的手腕滑动明显较少（0.37±0.34毫米；P = 0.0001），这表明神经的生理运动受到了限制。神经活动度的这种降低可能在腕管综合征的病理生理学中具有重要意义。
