“…It is possible to infer, from this, that the children were not able to perform such activities because, in the second assessment, most of them were at the end of the second trimester of life. Our results corroborate the findings of another study on motor performance, coordination and language which observed that language had the lowest scores than the control group and that such developmental area is the most compromised in children with Down syndrome [25,26].…”

Objective: To verify the effects of early stimulation on the motor and cognitive development of children with Down syndrome taking part of an interdisciplinary early stimulation group at a Special Child Integration Center. Methods: Prospective Observational Study carried out at a Special Child Integration Center with children from 0 to less than 1 year of age, taking part of an early stimulation group and who were not participating in any other intervention. Children included were evaluated in the rehabilitation sector of the institution. The instrument used was the Child Behavior Development Scale and the data were presented descriptively with percentage based on the answers of individual behavior and on the group average pre- and post-intervention. Results: The group was homogeneous regarding the characteristics and possible factors associated to developmental delay. In the motor and cognitive performance, individually all children had an improvement on their performance equal or greater than 50% in comparison to the initial assessment, and the group had a 62.5% growth in comparison to the initial evaluation. Conclusion: In group early stimulation brings benefits on the motor and cognitive development of children with Down syndrome in interdisciplinary care.Key-words: early stimulation, child development, Down syndrome.

“…The filing of the protocol criteria also allows for its improvement, in this sense, after the analyzes, but one criterion was added to the others, constituting the number 9: verification of the number of words in the statement. This criterion was added because it is pointed out as an important measure in the context of altered language development (3,5) , as children with language disorders produce sentences with fewer words (2) .…”

“…Despite the importance that morphosyntax has in the development of child communication, it has been neglected in Brazilian studies because it is not possible to measure it reliably in Brazilian Portuguese. Regarding the specific verification of the morphological and syntactic structure of the language, only the MLU -Mean Length Utterance has been used as a measurement procedure in recent years (3,4) . In this context, the construction or cross-cultural adaptation of syntactic assessment instruments represents a challenge for advances in the evaluation of children's language.…”

Introduction: the use of language assessment instruments in the area of speech-language-therapy is essential for the diagnosis and, consequently, for therapeutic planning. In Brazil, there is a shortage of instruments constructed and validated in the morphosyntax area. Morphosyntactic Evaluation Protocol (MEP) was constructed based on the main syntactic characteristics of the period of acquisition of children’s language, on the Portuguese grammatical structure and the application in a pilot study. Objective: To verify the validity of MEP content. Methods: for the validation process, the instrument was applied and analyzed through a questionnaire by three judges, a linguist and two speech-language specialists with experience in assisting children with Language Development Disorder. The Index of Judges’ Reliability was used to compare the results of the protocol application and the Cronbach’s Alpha tests, Spearman-Brown and Content Validity Index (CVI) in the questionnaire responses. Results: the statistical tests applied in the validation of content legitimized the reliability of the instrument with indexes considered substantial for both alpha coefficients, higher than 0.80, Spearman and the CVI test had a maximum concept of 1.0. Conclusion: there were compliance and compatibility in the answers of the experts, which indicates the reliability of the instrument. The results of the statistical tests legitimize the reliability of the instrument with indexes considered substantial for alpha and Spearman coefficient. In the future, the protocol may help characterize the syntactic profile of children with language developmental disorder.

“…This result does not demonstrate the tendency for girls to acquire words at a slightly faster rate than boys in general studies. However, this may be justified by the fact of individual differences 36,37 .…”

Purpose: to investigate the existence of a relationship between vocabulary and measures of mean length of utterance in children in their language development phase. Methods: the sample consisted of 72 children aged 2 to 4 years, 11 months and 29 days, 36 boys and 36 girls, with typical language development, evenly distributed into age groups, enrolled in kindergartens with the public school system, in Santa Maria, RS, Brazil. Videos of the spontaneous speech of each subject were made, and then, the analysis of the vocabulary and Mean Length of Utterance took place. Statistical analysis was performed using the Statistical Analysis System program, version 9.2 and Spearman correlation coefficient, with a significance level of p <0.05. Results: the influence of gender in the Mean Length of Utterance correlation and vocabulary was observed. There was a difference between the ages of 2 and 4 years. Conclusion: vocabulary development promotes mean length utterance, indicating positive correlation between gender and age range.
