Abstract

The Finger Tapping Test (FTT) is a widely utilized measure to assess lateralized motor speed and dexterity. The current study sought to cross-validate an abbreviated version of the FTT (i.e., M of Trials 3–5) and to evaluate a novel abbreviated method (i.e., M of three trials within five taps of each other; “3 within 5”) to examine their respective effectiveness as a predictor of full-score performance based on a traditional administration procedure. The results showed that the abbreviated methods accurately predicted the full-test score, and any statistically significant differences that emerged were small based on effect size analysis and unlikely to be clinically meaningful. These findings were consistent across genders, among older adults, and among individuals displaying significant inter-trial tapping variability and thus requiring lengthier administration time. Classification accuracy statistics for the detection of impairment and performance validity status were high for both abbreviated methods. The results support two valid options for shortening the duration of the FTT. Both methods, used independently or in combination, are compatible with traditional administration procedures.

摘要

手指敲击测试 (FTT) 是一种广泛使用的措施，用于评估横向运动速度和灵活性。当前的研究试图交叉验证 FTT 的简化版本（即试验 3-5 的M）并评估一种新颖的简化方法（即M三个试验在彼此五次水龙头内；“5 分之内 3”）来检查它们各自作为基于传统管理程序的满分表现预测指标的有效性。结果表明，简化方法准确地预测了完整测试分数，并且根据效应量分析，出现的任何统计显着差异都很小，不太可能具有临床意义。这些发现在不同性别、老年人以及显示出显着的试验间敲击变异性并因此需要更长给药时间的个体中是一致的。两种简化方法的损伤检测和性能有效性状态的分类准确性统计数据都很高。结果支持缩短 FTT 持续时间的两个有效选项。两种方法，
