This study aimed to investigate chewing efficiency in children with speech sound disorders (SSD). With a focus on those with motor speech disorders (MSD).
A clinical sample of 101 children with SSDs (78 with MSD), aged 4-9 years, and a control group of 76 typically developing (TD) children participated. Chewing efficiency was assessed using the two-colour Hue-Check chewing gum test. A computer-based image analysis measured colour mixing after 20 chewing cycles, generating the outcome variable SDHue.
An independent samples t-test showed that children with SSD chewed less efficiently than TD children. A one-way ANOVA revealed that children with MSD + (i.e., all children with MSD who also had concomitant language-oriented diagnoses [LD] and/or oral motor developmental delay [ODD]) aged 7-9 years had significantly lower chewing efficiency than age-matched TD peers (p < 0.001, η = 0.305).
Children with MSD demonstrated reduced chewing efficiency compared to their TD peers. Possibly reflecting a broader, not yet fully understood, symptom complex. Oral motor developmental delay (ODD) was common across the entire SSD group. These findings underline the importance of future research exploring symptom interrelations and guiding targeted interventions.
本研究旨在调查言语声音障碍（SSD）儿童的咀嚼效率，重点关注运动性言语障碍（MSD）儿童。
101名4至9岁的SSD儿童（78名患有MSD）的临床样本以及76名发育正常（TD）儿童的对照组参与了研究。使用双色色调检查口香糖测试评估咀嚼效率。基于计算机的图像分析在20次咀嚼循环后测量颜色混合情况，生成结果变量SDHue。
独立样本t检验显示，SSD儿童的咀嚼效率低于TD儿童。单因素方差分析表明，7至9岁的MSD+儿童（即所有患有MSD且同时伴有语言相关诊断[LD]和/或口腔运动发育迟缓[ODD]的儿童）的咀嚼效率显著低于年龄匹配的TD同龄人（p<0.001，η=0.305）。
与TD同龄人相比，MSD儿童的咀嚼效率降低。这可能反映了一个更广泛的、尚未完全理解的症状复合体。口腔运动发育迟缓（ODD）在整个SSD组中很常见。这些发现强调了未来研究探索症状相互关系并指导针对性干预的重要性。
