TL;DR: In this article , the authors describe communication-related parameters (i.e., intelligibility, speech rate, and communication efficiency) and their developmental courses in children with neurological conditions against the background of typical development.
Abstract: This study aimed to describe communication-related parameters (i.e., intelligibility, speech rate, and communication efficiency) and their developmental courses in children with neurological conditions against the background of typical development. In addition, interrelations between the developmental courses of communication-related parameters and auditory-perceptual ratings related to speech subsystems were investigated.Fourteen children with neurological conditions (CNC) and 14 typically developing children (CTD), matched for age and gender (four girls; 5;1-8;4 [years;months] at first examination), were assessed at three points in time over an 18-month period. Speech samples were collected using the Bogenhausener Dysarthrie Skalen-Kindliche Dysarthrien (English: Bogenhausen Dysarthria Scales-Childhood Dysarthria), a German tool for the assessment of childhood dysarthria. To assess intelligibility, naïve listeners transcribed audio samples of sentence repetitions of the children. Speech rate was measured by acoustic analyses, and communication efficiency was determined by multiplying the proportion of correctly transcribed syllables with speech rate. Age normalization was performed following a recently published approach.On the group level, CNC had conspicuous raw and normalized scores for the three communication-related parameters and were more variable than the CTD group regarding their developmental courses. These differences were more pronounced for intelligibility than for speech rate. A strong relationship between communication-related and speech subsystems-related auditory-perceptual characteristics was apparent only between intelligibility and articulation/resonance.For the first time, age-normalized scores for communication-related parameters were reported in children with neurological disorders and put into a developmental context within the framework of a longitudinal study. Age-normalized intelligibility was more vulnerable to large developmental changes than speech rate and was best predicted by changes in articulation and resonance. Overall, this study may contribute to a more comprehensive and valid clinical assessment of childhood dysarthria and to a better understanding of its developmental dynamics.

TL;DR: High mean coherence values in preschool children’s left frontotemporal and frontocentral pairs are a positive factor for development of speech in process of ontogenesis, as demonstrated by the data of ECG coherent analysis.
Abstract: Speech occupies a special place in formation of cognitive functions. Delay in tempos of speech development can lead to disorders in formation of the highest mental functions. Aim. To study the character of space-time integration of cerebral zones in children with different variants of speech disontogenesis in the course of prospective study by the data of ECG coherent analysis. Materials and methods. 34 children aged 3-11 years were examined by means of quantitative ECG mapping and estimation of mean coherence indices. All children were divided into two groups: group I included children with dysarthria, group II - children with motor dysphasia of development. In each group there were two age subgroups. The first subgroup involved children aged 3-6 years, the second- children aged 7-11 years. Results. It was demonstrated that in process of ontogenesis, different space-time integration models of cerebral zones which determine different clinical pictures of speech dysfunctions were formed. High mean coherence values in preschool children’s left frontotemporal and frontocentral pairs are a positive factor for development of speech in process of ontogenesis. Conclusions. The obtained data give an opportunity to assess the adequacy of therapeutic and correcting measures in age dynamics.

TL;DR: Describing the language development and articulation in children with different types of cerebral palsy found that children with diplegia developed similar levels both in comprehension and verbal expression, whereas those with tetraplegia and athetoid developed poorer verbal expression.
Abstract: Objective To characterize the language development and articulation in children with different types of cerebral palsy. Methods The data from 76 children with cerebral palsy who underwent standardized tests of speech and language were analyzed. The incidence and abnormal pattern were compared between groups. ResultsLanguage delay and/or dysarthria were noted in 73.1% of these subjects. Children with diplegia developed similar levels both in comprehension and verbal expression, whereas those with tetraplegia and athetoid developed poorer verbal expression. The incidence of language delay in children with diplegia, tetraplegia and athetoid were 45.95%, 90% and 64.7%, respectively. Dysarthria was found in all the children with tetraplegia, athetoid and ataxia, but only 48.65% of those with diplegia. Conclusion Language disorders were common in children with cerebral palsy, especially those with athetoid and tetraplegia.
