To develop an objective and quantitative clinical evaluation tool that can be used for diagnosis and severity assessment of dysarthria in patients with stroke.
A prototype test comprising 23 items was developed to test the function of each speech organ. The scoring of the prototype test was based on the analysis of the result values obtained from 50 healthy individuals. The test was performed for 50 patients with stroke who were suspected to have dysarthria. For evaluating the correlation between each prototype test item and the Urimal Test of Articulation and Phonation (U-TAP), the odds ratio was obtained for each result, based on which the final test items for composing the Korea Dysarthria Test (KDT) were selected. The validity of the test was evaluated using the receiver operator characteristic (ROC) curve and the area under the curve. We used the intraclass correlation coefficients to quantify inter- and intra-rater reliability. The Spearman correlation coefficient was used for examining the correlation between the KDT and the Speech Mechanism Screening Test and U-TAP.
Among the 23 prototype test items, 16 exhibiting significant results were finally selected as the KDT. The higher score of the KDT is reflected the better speaking function. The sensitivity and specificity of the KDT were shown to be high at the cutoff value of 76.50 point.
KDT is a useful evaluation tool for dysarthria, showing a significant correlation with SMST and U-TAP.
开发一种客观、定量的临床评估工具，用于中风患者构音障碍的诊断和严重程度评估。
开发了一个包含23个项目的原型测试，以测试每个言语器官的功能。原型测试的评分基于对50名健康个体所得结果值的分析。对50名疑似患有构音障碍的中风患者进行了该测试。为了评估每个原型测试项目与发音和发声尿嘧啶测试（U-TAP）之间的相关性，计算了每个结果的优势比，并据此选择了构成韩国构音障碍测试（KDT）的最终测试项目。使用受试者工作特征（ROC）曲线和曲线下面积评估该测试的有效性。我们使用组内相关系数来量化评分者间和评分者内的可靠性。使用斯皮尔曼相关系数来检验KDT与言语机制筛查测试和U-TAP之间的相关性。
在23个原型测试项目中，最终选择了16个显示出显著结果的项目作为KDT。KDT得分越高，表明说话功能越好。在截断值为76.50分时，KDT的敏感性和特异性较高。
KDT是一种用于构音障碍的有用评估工具，与言语机制筛查测试和U-TAP显示出显著相关性。
