本研究的目的是探讨腕管综合征（CTS）在持续精确捏指过程中对手指力量控制的影响。11名CTS个体和11名年龄和性别匹配的健康志愿者参与了这项研究。受试者被指示等距捏一个仪器设备60秒，具有稳定的力输出。在前30 s提供力输出的视觉反馈，但在剩余30 s中移除。检查夹持力的准确性、变异性和手指间相关性。CTS导致力准确性降低和力可变性增加，特别是在没有视觉反馈的情况下（p < 0.001）。然而，CTS并不影响手指间的力变异性或力相关性的结构（p > 0.05）。对于CTS组和健康组，拇指的力比食指的力更不准确且更易变（p < 0.001）。与CTS相关的感觉运动缺陷导致在持续精确捏期间手指力不准确和不稳定。这项研究揭示了精细运动控制的基本和病理生理机制，并有助于开发新的诊断和评估CTS的策略。
The purpose of this study was to investigate effects of carpal tunnel syndrome (CTS) on digit force control during a sustained precision pinch. Eleven CTS individuals and 11 age- and gender-matched healthy volunteers participated in the study. The subjects were instructed to isometrically pinch an instrumented apparatus for 60 s with a stable force output. Visual feedback of force output was provided for the first 30 s but removed for the remaining 30 s. Pinch forces were examined for accuracy, variability, and inter-digit correlation. CTS led to a decrease in force accuracy and an increase in amount of force variability, particularly without visual feedback (p < 0.001). However, CTS did not affect the structure of force variability or force correlation between digits (p > 0.05). The force of the thumb was less accurate and more variable than that of the index finger for both the CTS and healthy groups (p < 0.001). Sensorimotor deficits associated with CTS lead to inaccurate and unstable digit forces during sustained precision pinch. This study shed light on basic and pathophysiological mechanisms of fine motor control and aids in development of new strategies for diagnosis and evaluation of CTS.
