DATASET FOR STUDY: Enhanced paper grip test for foot strength assessment in healthy young adults: test-retest reliability and comparison with handgrip test

This is the raw dataset for the study that assessed the reliability of the Enhanced Paper Grip Test (EPGT), a simple and efficient tool for evaluating foot strength, and its correlation with the handgrip test in healthy young adults. Twenty-one participants healthy young completed two sessions 10–14 days apart. EPGT demonstrated good to excellent test-retest reliability (ICC=0.92 right, 0.90 left) but showed lower absolute reliability, with coefficients of variation (CVs) ranging from 8.2% to 15.3%. The handgrip test exhibited excellent reliability (ICC=0.99 right, 0.98 left) and superior consistency (CVs=3.1–4.2%). Inter-limb asymmetry reliability was moderate to excellent for both tests (ICC=0.82–0.83). Moderate correlations were observed between EPGT and handgrip strength (r=0.47–0.56). EPGT’s simplicity and ability to assess foot strength make it a valuable tool, though further research is needed to improve its absolute reliability and applicability in different age groups and patient populations.本数据集为一项研究的原始数据，该研究旨在评估增强式握纸试验（Enhanced Paper Grip Test, EPGT）的信度及其与健康青年人群握力试验的相关性——增强式握纸试验是一种简便高效的足部力量评估工具。本研究共纳入21名健康青年受试者，受试者需间隔10至14天完成两次测试。结果显示，增强式握纸试验具备良好至优秀的重测信度（组内相关系数（Intraclass Correlation Coefficient, ICC）：右侧0.92，左侧0.90），但绝对信度较低，变异系数（Coefficient of Variation, CVs）范围为8.2%至15.3%。握力试验则表现出优秀的信度（ICC=0.99右侧、0.98左侧）及更优的一致性（CVs=3.1%~4.2%）。两项测试的肢体间不对称性信度均处于中等至优秀水平（ICC=0.82~0.83）。研究观察到增强式握纸试验与握力强度之间存在中等程度的相关性（相关系数r=0.47~0.56）。增强式握纸试验因其操作简便且可有效评估足部力量，成为极具价值的评估工具；不过仍需开展进一步研究，以提升其绝对信度，并拓展其在不同年龄群体与患者人群中的适用性。
