Abstract

The effects of forearm rotation and metacarpophalangeal (MP) flexion on carpal tunnel pressure were investigated in 17 healthy adults who had no evidence of carpal tunnel syndrome (CTS). Pressure was continuously recorded with a saline-filled catheter inserted into the carpal tunnel and connected to a pressure transducer while test subjects slowly rotated the forearm from full pronation to full supination. Forearm rotation was repeated with MP flexion of 0 degrees, 45 degrees, and 90 degrees. Both forearm rotation and MP flexion, and their interaction term, significantly affected carpal tunnel pressure and accounted for most of the variability in the data. Highest mean pressures (55 mmHg) were recorded in full supination and 90 degrees MP flexion and lowest pressures (12 mmHg) were recorded at 45 degrees pronation and 45 degrees MP flexion. These data may be useful in the design of tasks and hand tools in the management and prevention of CTS.

摘要

在17名无腕管综合征（CTS）迹象的健康成年人中，研究了前臂旋转和掌指关节（MP）屈曲对腕管压力的影响。在测试对象将前臂从完全旋前缓慢旋转到完全旋后的过程中，用插入腕管并连接到压力传感器的充生理盐水导管连续记录压力。在前臂旋转时分别进行0度、45度和90度的MP屈曲重复实验。前臂旋转和MP屈曲及其交互项均显著影响腕管压力，并解释了数据中的大部分变异性。在完全旋后和90度MP屈曲时记录到最高平均压力（55 mmHg），在45度旋前和45度MP屈曲时记录到最低压力（12 mmHg）。这些数据可能有助于设计管理和预防CTS的任务及手部工具。
