The main objective of this study was to determine the association of grip strength with carpal tunnel syndrome (CTS) for occupational workers exposed to the risk of CTS. Experiments were performed on 60 workers, 15 each from four occupations. Grip strength was measured using a hand dynamometer. Electrophysiological experiments were conducted to measure CTS. Three levels of CTS were identified on the basis of latency value and motor nerve conduction velocity, viz., mild, moderate and severe. Statistical results suggest that workers who have CTS lose their grip strength, and higher levels of CTS lead to greater reduction in the grip strength. Another objective of the article was to investigate the association of grip strength with three individual factors of occupational workers, viz., body mass index, age and work experience. It is statistically inferred using Fisher's exact test that grip strength is not associated with any of these individual factors.
本研究的主要目的是确定握力与腕管综合征（CTS）之间的关联，以评估职业工人接触 CTS 风险的情况。实验在 60 名工人中进行，每个职业 15 人。使用手持测力计测量握力。进行电生理学实验以测量 CTS。根据潜伏期值和运动神经传导速度，将 CTS 分为三个级别，即轻度、中度和重度。统计结果表明，患有 CTS 的工人会失去握力，而 CTS 程度越高，握力下降幅度越大。本文的另一个目的是研究握力与职业工人的三个个体因素（即体重指数、年龄和工作经验）之间的关联。Fisher 确切检验统计推断表明，握力与这些个体因素均无关。
