The aims of this study were twofold: first, to develop and validate a timed test of unimanual and bimanual dexterity suitable for those with disability affecting hand function; second, to explore relationships between unimanual and bimanual completion times.
We developed the Tyneside Pegboard Test (TPT), an electronically timed test with three peg sizes, incorporating an asymmetrical bimanual task. Nine hundred and seventy-four participants (455 males, 519 females; age range 4-80y) provided normative data. Test-retest reliability and construct validity were assessed (50 adults: 14 males, 36 females; 15-73y) on two occasions 2 weeks apart. Bimanual and unimanual completion times were measured in 87 children (51 males, 36 females) with unilateral cerebral palsy (CP) and 498 individuals in a comparison group (238 males, 260 females; 5-15y).
The comparison group showed an asymmetrical U-shaped relationship between completion times and age. Intraclass correlation coefficients ranged from 0.74 to 0.91, indicating moderate test-retest reliability. There was a negative relationship between average TPT bimanual times and Purdue pegboard bimanual scores (Spearman's rho -0.611, degrees of freedom 44, p<0.001). Children with unilateral CP had greater prolongation of bimanual than unimanual completion times compared with the comparison group (mean difference 20.31s, 95% confidence interval 18.13-22.49, p<0.001).
The TPT is accessible for those with impaired hand function. Children with unilateral CP demonstrated disproportionate bimanual deficits, even allowing for unimanual dexterity: this has implications for therapy.
We developed an adapted, electronically timed 9-hole pegboard test. Our modifications facilitate use by those with disability affecting hand function. The test incorporates an asymmetrical bimanual task. Children with unilateral cerebral palsy showed disproportionate bimanual dexterity deficits even allowing for unimanual dexterity.
本研究旨在实现两个目标：首先，开发并验证一种适用于手部功能障碍者的单侧和双手灵巧性计时测试；其次，探讨单手和双手完成时间之间的关系。
我们开发了泰恩赛德钉板测试（TPT），这是一种电子计时测试，有三种钉大小，包括非对称双手任务。974 名参与者（455 名男性，519 名女性；年龄范围 4-80 岁）提供了规范数据。在两周的两次测试中评估了测试-重测信度和结构效度（50 名成年人：14 名男性，36 名女性；15-73 岁）。在单侧脑瘫的 87 名儿童（51 名男性，36 名女性）和 498 名对照组（238 名男性，260 名女性；5-15 岁）中测量了双手和单手完成时间。
对照组的完成时间与年龄之间呈不对称 U 形关系。组内相关系数范围为 0.74 至 0.91，表明测试-重测具有中等可靠性。TPT 双手平均时间与普渡钉板双手得分呈负相关（Spearman rho-0.611，自由度 44，p<0.001）。与对照组相比，单侧脑瘫儿童的双手完成时间延长程度大于单手完成时间（平均差异 20.31 秒，95%置信区间 18.13-22.49，p<0.001）。
TPT 可用于手部功能障碍者。单侧脑瘫儿童表现出不成比例的双手灵巧性缺陷，即使考虑到单手灵巧性也是如此：这对治疗有影响。
我们开发了一种经过改编的、电子计时的 9 孔钉板测试。我们的修改便于手部功能障碍者使用。该测试包括非对称双手任务。单侧脑瘫儿童即使考虑到单手灵巧性，也表现出不成比例的双手灵巧性缺陷。
