Some children with cerebral palsy have articulation disorders that are resistant to conventional speech therapy. The aim of this study was to investigate whether the visual feedback method of electropalatography (EPG) could be an effective tool for treating five children (mean age of 9.4 years) with dysarthria and cerebral palsy and to explore whether training improved the posteriorly placed articulation of the Swedish dental/alveolar target consonants /t/, /d/, /n/ and /s/ produced in different positions. An EPG analysis was conducted and some of the data were combined with a perceptual analysis. A more anterior placement was seen after treatment for the target sounds. Features of diagnostic importance revealed were unusual tongue-palate contacts, such as double articulation and abnormally retracted articulation. A possible change in stop closure duration was indicated. The results suggest that EPG could be of potential benefit for diagnosing, treating and describing articulation errors associated with cerebral palsy.
一些患有脑瘫的儿童存在对传统言语治疗有抵抗性的构音障碍。本研究的目的是调查电子腭图（EPG）的视觉反馈方法是否可以成为治疗五名（平均年龄9.4岁）患有构音障碍和脑瘫儿童的有效工具，并探索训练是否改善了在不同位置发出的瑞典齿龈/齿槽目标辅音/t/、/d/、/n/和/s/后置发音。进行了EPG分析，并将一些数据与感知分析相结合。治疗后目标音出现了更靠前的位置。所揭示的具有诊断重要性的特征是不寻常的舌腭接触，如双重发音和异常后缩发音。表明塞音闭塞持续时间可能发生了变化。结果表明，EPG对于诊断、治疗和描述与脑瘫相关的构音错误可能具有潜在益处。
