在临床筛选后，我们使用高分辨率（10-22 MHz）超声检查了16名对照组和12名非特异性手臂疼痛（也称为重复性劳损）患者腕部正中神经的运动。影像学检查在腕管近端进行，腕关节处于中立位，伸展30度，屈曲30度。在对照组中，正中神经的位置是4.8（SE = 0.4）mm以上的径向与手腕弯曲比与手腕延长。在12名手臂疼痛患者的平均变化只有1.2（SE = 0.5）毫米。看来，超声成像可能有助于诊断非特异性手臂疼痛，目前没有明确的诊断测试的条件。通过超声成像观察到的神经运动减少证实了以前的磁共振成像工作。
Following clinical screening, we examined movement of the median nerve at the wrist using high-resolution (10-22 MHz) ultrasound in 16 controls and 12 patients with non-specific arm pain (also referred to as repetitive strain injury). Imaging was performed just proximal to the carpal tunnel with the wrist in neutral, 30 degrees of extension and 30 degrees of flexion. In control subjects the position of the median nerve was 4.8 (SE = 0.4) mm more radial with the wrist flexed than with the wrist extended. In the twelve arm pain patients the average change was only 1.2 (SE = 0.5) mm. It appears that ultrasound imaging may be helpful in diagnosing non-specific arm pain, a condition for which there are no well-defined diagnostic tests at present. The reduced nerve movement seen with ultrasound imaging confirms previous work with magnetic resonance imaging.
