Change in carpal tunnel pressures that result from externally applied forces to the palm of the hand were assessed in five cadaveric specimens. MIKRO-TIP transducers were percutaneously placed into the carpal tunnel at the level of the hook of the hamate. A 1 kg force was applied to the palm of the hand in 16 separate locations. Significant elevations in carpal tunnel pressure were observed for external forces applied over the flexor retinaculum (103 mm Hg) and also for the hypothenar (37 mm Hg) and thenar (75 mm Hg) areas adjacent to the distal aspect of the carpal tunnel. These data demonstrate that the application of external forces on the palm of cadaver hands increases carpal tunnel pressure and the magnitude of the pressure change in the carpal tunnel depends on the location of the applied force.
在五个尸体标本中评估了因对手掌施加外力而导致的腕管压力变化。将MIKRO-TIP传感器经皮放置在钩骨钩水平的腕管内。在手掌的16个不同位置施加1千克的力。观察到在屈肌支持带上方施加外力时腕管压力显著升高（103毫米汞柱），在腕管远端相邻的小鱼际（37毫米汞柱）和大鱼际（75毫米汞柱）区域施加外力时也观察到腕管压力显著升高。这些数据表明，在尸体手部手掌上施加外力会增加腕管压力，且腕管内压力变化的幅度取决于外力施加的位置。
