硬币旋转任务(CRT)是一种简单、方便且经济高效的精神运动处理速度测量方法，在路易斯安那州立大学健康科学系统的神经学检查中已使用了近20年。在CRT中，参与者用拇指、食指和中指将硬币旋转180度，持续10秒。在目前的研究中，我们试图通过以医院为基础的样本来验证CRT，方法是确定该任务在标准测量--凹槽钉板测试(GPT)上检测精神运动加工速度障碍的敏感性和特异性。参与者包括从医院获得的161名参与者的样本。研究发现，CRT与许多运动功能指标显著相关。使用二进制ROC曲线分析，CRT预测GPT受损的灵敏度和特异度分别为0.80和0.62，当使用13或更少的硬币旋转时，CRT预测非优势手性能的灵敏度和特异度分别为0.83和0.43。这些结果支持CRT作为一种方便和廉价的精神运动处理速度筛查工具在临床环境中的应用。
The coin rotation task (CRT) is a simple, convenient, and cost-effective measure of psychomotor processing speed that has been used in neurologic examinations at the Louisiana State University Health Sciences system for almost 20 years. In the CRT, participants rotate a coin through serial 180-degree turns using the thumb, index, and middle fingers for 10 seconds. In the current study, we sought to validate the CRT on a hospital-based sample by determining the task’s sensitivity and specificity in detecting psychomotor processing speed impairment on a criterion measure, the Grooved Pegboard Test (GPT). Participants included a sample of 161 participants obtained in a hospital setting. The CRT was found to be significantly correlated with a number of measures of motor functioning. Using a binary ROC curve analysis, the CRT predicted impairment on the GPT with .80 sensitivity and .62 specificity for dominant hand performance and .83 sensitivity and .43 specificity for nondominant hand performance when a cut score of 13 or fewer coin rotations was utilized. These results support the utility of the CRT as a convenient and inexpensive psychomotor processing speed screening tool in clinical settings.
