The physiological and perceptual characteristics of persistent dysarthria exhibited by a 14 year-old boy, following a severe traumatic brain injury (TBI) were investigated. The subject's speech and motor speech mechanism were comprehensively evaluated both perceptually and physiologically, and the findings were compared with those of a non-neurologically impaired control subject, matched for age and sex, and a number of control groups from previous studies. Overall, the assessments indicated that the major motor speech deficits demonstrated by the subject included severely reduced tongue function, and moderately impaired lip, laryngeal, and velopharyngeal function. Respiratory function was found to be mildly impaired. Perceptual assessments indicated that the subject's speech was severely impaired in relation to rate, pitch variation, and consonant precision, with a moderate impairment in overall intelligibility. The effects of a severe TBI on the functioning of the child's motor speech mechanism were discussed. The clinical implications for the assessment and treatment of dysarthria in childhood following severe TBI were highlighted.
对一名14岁男孩在严重创伤性脑损伤（TBI）后出现的持续性构音障碍的生理和感知特征进行了调查。对该受试者的言语和运动言语机制进行了全面的感知和生理评估，并将结果与一名年龄和性别匹配的非神经受损对照受试者以及先前研究中的多个对照组进行了比较。总体而言，评估表明该受试者表现出的主要运动言语缺陷包括舌功能严重减退，唇、喉和腭咽功能中度受损。发现呼吸功能轻度受损。感知评估表明，该受试者的言语在语速、音高变化和辅音清晰度方面严重受损，整体可懂度中度受损。讨论了严重TBI对儿童运动言语机制功能的影响。强调了严重TBI后儿童构音障碍评估和治疗的临床意义。
