Childhood apraxia of speech (CAS) causes inconstant oromotor production. We investigated the clinical efficacy of repeated urimal test of articulation and phonation (U-TAP) in CAS patients. Twenty-eight children were recruited: 19 with CAS and 9 with functional articulation disorder (FAD). Four age-matched typically developing children were also recruited. U-TAP was performed twice repeatedly, and the error rate of consonant accuracy (CA) was measured. Preschool Receptive-Expressive Language Scale (PRES) was also performed. The mean U-TAP CA showed a significant difference between the three groups, with 42.04% for CAS, 77.92% for FAD, and 99.68% for the normal group ( < 0.05). The mean difference between the two U-TAP CAs was 10.01% for CAS, 0.82% for FAD, and no difference for the normal group, revealing a significant intergroup difference between CAS and FAD ( < 0.05). For the expressive and receptive PRES scores, CAS group showed significantly decreased results compared to FAD and normal group. Only in the CAS group, expressive PRES showed significant decrease rather than receptive PRES score. The CAS group showed a significant difference in the two U-TAP CA compared to the FAD and normal groups. This result implies that repeated U-TAP can be useful for supportive diagnostic tool for CAS by detecting poor reliability of phonation.
儿童言语失用症（CAS）会导致口面部运动产生不稳定。我们研究了重复口面部发音和发声测试（U-TAP）对CAS患者的临床疗效。招募了28名儿童：19名患有CAS，9名患有功能性构音障碍（FAD）。还招募了4名年龄匹配的发育正常儿童。重复进行两次U-TAP，并测量辅音准确性（CA）的错误率。还进行了学龄前接受-表达语言量表（PRES）测试。三组之间的平均U-TAP CA存在显著差异，CAS组为42.04%，FAD组为77.92%，正常组为99.68%（<0.05）。CAS组两次U-TAP CA的平均差异为10.01%，FAD组为0.82%，正常组无差异，显示CAS组和FAD组之间存在显著的组间差异（<0.05）。对于表达性和接受性PRES评分，CAS组与FAD组和正常组相比结果显著降低。仅在CAS组中，表达性PRES显示出显著下降，而接受性PRES评分未下降。与FAD组和正常组相比，CAS组在两次U-TAP CA上存在显著差异。这一结果表明，重复进行U-TAP通过检测发声的低可靠性，可能有助于作为CAS的辅助诊断工具。
