Cross-sectional study.
The WorkAbility Rate of Manipulation Test (WRMT), an adaptation of the Minnesota Manual Dexterity Test (MMDT), contains a revised board and protocols to improve its utility for therapy or fitness assessment.
To describe the development and preliminary psychometric properties of WRMT.
Sixty-six healthy participants completed MMDT and WRMT in a random order followed by a user experience survey. We compared tests using repeated-measures analysis of variance, test-retest reliability, and examined agreement between tests.
Despite the similarities of these 2 instruments, the different administration protocols resulted in statistically different score distributions (P < .001). Results supported good test-retest reliability of WRMT (placing test ICC = 0.88-0.90 and turning test ICC = 0.68-0.82). The WRMT correlated moderately with MMDT (r = 0.81 in placing test and r = 0.44-0.57 in turning test). Bland-Altman plot showed that the differences in completion time were 3.8 seconds between placing tests and 19.6 (both hands), 0.3 (right hand), and 3.9 (left hand) seconds between turning tests. Overall, participants felt that the instruction of WRMT was easier to follow (44%) and preferred its setup, color, and depth of the test board (49%). Time required to complete 1 panel of 20 disks correlated highly with the time needed to finish a complete trial of 60 disks in both MMDT (r = 0.91-0.97) and WRMT (r = 0.88-0.95).
Caution is warranted in comparing scores from these 2 test variants.

横断面研究。
操作能力测试（WRMT）是明尼苏达手动灵巧度测试（MMDT）的改编版，包含改良的测试板和协议，以提高其在治疗或健身评估中的实用性。
描述 WRMT 的开发和初步心理测量学特性。
66 名健康参与者按随机顺序完成 MMDT 和 WRMT，然后完成用户体验调查。我们使用重复测量方差分析、测试-重测信度比较测试，并检查测试之间的一致性。
尽管这两种仪器相似，但不同的管理协议导致分数分布存在统计学差异（P<0.001）。结果支持 WRMT 的良好测试-重测信度（位置测试 ICC=0.88-0.90，转动测试 ICC=0.68-0.82）。WRMT 与 MMDT 中度相关（位置测试 r=0.81，转动测试 r=0.44-0.57）。Bland-Altman 图显示，放置测试的完成时间差异为 3.8 秒，转动测试的完成时间差异为 19.6 秒（双手）、0.3 秒（右手）和 3.9 秒（左手）。总的来说，参与者认为 WRMT 的指令更容易遵循（44%），并更喜欢其设置、颜色和测试板的深度（49%）。完成 20 个磁盘的 1 个面板所需的时间与完成 60 个磁盘的整个试验所需的时间高度相关，在 MMDT（r=0.91-0.97）和 WRMT（r=0.88-0.95）中均如此。
在比较这两种测试变体的分数时应谨慎。
