Eye-hand coordination (EHC) plays a critical role in daily activities and is affected by monocular vision impairment. This study evaluates existing EHC tests to detect performance decline under monocular conditions, supports the assessment and monitoring of vision rehabilitation, and quantifies the binocular advantage of each test.
A total of 70 healthy sports students (aged 19-30 years) participated in four EHC tests: the Purdue Pegboard Test (PPT), Finger-Nose Test (FNT), Alternate Hand Wall Toss Test (AHWTT), and Loop-Wire Test (LWT). Each participant completed the tests under both binocular and monocular conditions in a randomized order, with assessments conducted by two independent raters. Performance differences, binocular advantage, effect sizes, and interrater reliability were analyzed.
Data from 66 participants were included in the final analysis. Significant performance differences between binocular and monocular conditions were observed for the LWT ( < 0.001), AHWTT ( < 0.001), and PPT ( < 0.05), with a clear binocular advantage and large effect sizes (SMD range: 0.583-1.660) for the AHWTT and LWT. Female participants performed better in fine motor tasks, while males demonstrated superior performance in gross motor tasks. Binocular performance averages aligned with published reference values.
The findings support the inclusion of the LWT and AHWTT in clinical protocols to assess and assist individuals with monocular vision impairment, particularly following sudden uniocular vision loss. Future research should extend these findings to different age groups and clinically relevant populations.
眼手协调（EHC）在日常活动中起着关键作用，并受到单眼视力损害的影响。本研究评估现有的眼手协调测试，以检测单眼条件下的性能下降，支持视力康复的评估和监测，并量化每个测试的双眼优势。
共有70名健康的体育专业学生（年龄在19 - 30岁之间）参加了四项眼手协调测试：普渡钉板测试（PPT）、指鼻测试（FNT）、交替手抛墙测试（AHWTT）和环线测试（LWT）。每位参与者以随机顺序在双眼和单眼条件下完成测试，由两名独立的评估者进行评估。分析了性能差异、双眼优势、效应大小和评估者间信度。
66名参与者的数据纳入最终分析。在环线测试（<0.001）、交替手抛墙测试（<0.001）和普渡钉板测试（<0.05）中，观察到双眼和单眼条件之间存在显著的性能差异，交替手抛墙测试和环线测试具有明显的双眼优势和较大的效应大小（标准化均数差范围：0.583 - 1.660）。女性参与者在精细运动任务中表现更好，而男性在粗大运动任务中表现更优。双眼性能平均值与已发表的参考值一致。
研究结果支持将环线测试和交替手抛墙测试纳入临床方案，以评估和帮助单眼视力损害的个体，特别是在突然单眼视力丧失之后。未来的研究应将这些结果扩展到不同年龄组和临床相关人群。
