Nasalance scores obtained with a nasometer can contribute to the diagnosis of oral-nasal balance disorders. The present study investigated how consistent such classifications are over time. Twenty-seven children with cleft lip and palate were recorded six times with a nasometer headset over the course of an orthodontic palatal expansion treatment. Nasalance scores were considered hypernasal when they were higher than 30% for a non-nasal sentence and hyponasal when they were below 50% for a nasal sentence. Based on the nasalance scores, normal nasalance was found in 42.6%, hyponasality in 34.0%, and hypernasality in 23.5% of 162 sound recordings. Only 7/ 27 (25.9%) of the children had the same nasalance-based classification over the six sessions. The others demonstrated variability that straddled two adjacent categories in 15/ 27 (55.6%) of cases and all three categories in 5/ 27 (18.5%) of cases. While clinicians may wish to assign a permanent oral-nasal balance classification to their patients, the study demonstrated that a subset may show unexpected variability over time.

The present study examined two task-relevant nonverbal abilities, visuospatial memory and gesture imitation, and investigated whether gesture-supported input influences sentence comprehension in children with DLD relative to typically developing (TD) peers. Forty Mandarin-speaking children (20 with DLD, 20 TD) completed a visuospatial memory task, a gesture imitation task, and a sentence comprehension task administered under gesture-supported and non-gesture conditions. A subset of 30 children also participated in an event-related potential (ERP) experiment during the comprehension task. Children with DLD performed more poorly than TD peers on visuospatial memory and gesture imitation. At the behavioural level, gesture-supported input was associated with higher comprehension accuracy and faster response times in both groups, with a larger facilitative pattern observed in the DLD group. Correlational analyses further showed that stronger visuospatial memory and gesture imitation were associated with better comprehension, particularly under gesture-supported conditions and especially among children with DLD. At the neurophysiological level, both groups showed N400 sensitivity to semantic congruency, but the DLD group exhibited attenuated neural responses and reduced modulation by gesture support. Taken together, the findings indicate systematic associations among visuospatial memory, gesture imitation, and gesture-supported sentence processing in DLD.
