腕管综合征（CTS）会对手部精细运动控制产生不利影响。拇指和食指之间的精确捏需要这些手指的协调运动，以实现可靠的任务性能。我们研究了在手指运动和手指接触过程中，CTS对精确捏功能的影响。11名CTS受试者和11名健全（ABL）对照者在精确捏运动（PPM）期间佩戴标记用于拇指和食指的运动捕获。受试者被指示重复执行PPM任务，并通过运动范围、运动轨迹的可变性和手指接触的精确性来评估表现。CTS组表现出较短的路径长度的手指端点和更大的变异性垫间距离和大多数关节角度的PPM运动。受试者与CTS也表现出缺乏精度的接触点上的数字垫和相对方向的数字在接触。腕管综合征损害了在整个运动和手指接触时进行精确捏的能力。研究结果可能有助于确定缺陷的手灵活性的功能评价的CTS。(c)2014骨科研究学会。由威利期刊公司出版J Orthop Res 32：786-792，2014年。
Carpal tunnel syndrome (CTS) can adversely affect fine motor control of the hand. Precision pinch between the thumb and index finger requires coordinated movements of these digits for reliable task performance. We examined the impairment upon precision pinch function affected by CTS during digit movement and digit contact. Eleven CTS subjects and 11 able-bodied (ABL) controls donned markers for motion capture of the thumb and index finger during precision pinch movement (PPM). Subjects were instructed to repetitively execute the PPM task, and performance was assessed by range of movement, variability of the movement trajectory, and precision of digit contact. The CTS group demonstrated shorter path-length of digit endpoints and greater variability in inter-pad distance and most joint angles across the PPM movement. Subjects with CTS also showed lack of precision in contact points on the digit-pads and relative orientation of the digits at contact. Carpal tunnel syndrome impairs the ability to perform precision pinch across the movement and at digit-contact. The findings may serve to identify deficits in manual dexterity for functional evaluation of CTS. (c) 2014 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
