目的：本研究的目的是调查的位移正中神经在腕管在手指运动在不同的手腕位置，使用横向超声在健康志愿者，以澄清在治疗腕管syndrome.Methods：50腕关节的腕管夹板的适当位置进行了评估，通过横向超声。分别在5个腕位（中立位、背屈600 °、掌屈60 °、尺屈40 °、桡屈100 °）、5指全伸位、5指全屈位和拇指全屈位下，观察正中神经在腕管内的位置。结果：正中神经在腕管内的位置明显高于腕管的位置（P < 0.01），正中神经在腕管内的位置明显高于腕管的位置（P < 0.01）。
Purpose: The purpose of this study was to investigate the displacement of the median nerve in the carpal tunnel during finger motion at varied wrist positions using transverse ultrasound in healthy volunteers, in order to clarify the appropriate position of a wrist splint in treating carpal tunnel syndrome.Methods: Fifty wrists of 25 asymptomatic volunteers were evaluated by transverse ultrasound. The location of the median nerve in the carpal tunnel was examined at 5 wrist positions (neutral, 600 dorsiflexion, 60 degrees palmar flexion, 40 degrees ulnar flexion, 100 radial flexion) with all 5 fingers in full extension, all 5 fingers in full flexion, and isolated thumb in full flexion, respectively.Results: The median nerve was located significantly (p
