Comparative study of the imitation ability in Specific Language Impairment and Autism Spectrum Impairment.

PURPOSE: To compare abilities of imitating generic and sequential motion gesture schemes in family routines among children with Autism Spectrum Disorder (ASD) and Specific Language Impairment (SLI) and to analyze the relation between imitation index and verbal production in the ASD group. METHODS: The sample was constituted by 2:1 pairing of 36 children, according to gender and age. All of them were diagnosed by a multidisciplinary team as belonging to the ASD group (n=24) or SLI group (n=12) and were under direct and indirect intervention in a school clinic. We have used the stage of imitation of the Assessment of Symbolic Maturity, which entails the imitation of nine generic and three sequential motion gesture schemes. RESULTS: There was a tendency to a better performance of the SLI group at imitating both generic and sequential gesture schemes. As we have related the ability of imitation to the verbal production in the ASD group, a direct relation between the production of phrases and the imitation of sequential schemes was detected. CONCLUSION: The ability to imitate gesture and sequential schemes could be compared, and a more prominent impairment was identified in children with autism. Among them, a direct significant relationship between the ability of imitating sequential gesture schemes in family routine and verbal production of words and sentences was verified.

Objetivo: Comparar as habilidades de imitação de esquemas gestuais simples e de sequências de ações em rotinas familiares de crianças com Transtorno do Espectro do Autismo (TEA) e com Transtorno Específico de Linguagem e Fala (TEL) e analisar a relação entre o índice de imitação e a produção verbal das crianças do Grupo TEA. Métodos: A amostra foi constituída pelo pareamento 2:1 de 36 crianças, de acordo com gênero e faixa etária. Todas foram diagnosticadas por equipe multidisciplinar como pertencentes ao Grupo TEA (n=24) ou grupo TEL (n=12) e atendidas em intervenção direta e indireta em clínicaescola. Utilizamos a etapa de imitação da Avaliação da Maturidade Simbólica, que compreende a imitação de nove esquemas gestuais simples e de três esquemas gestuais sequenciais. Resultados: Observamos tendência de melhor desempenho do Grupo TEL na imitação de esquemas gestuais tanto simples como sequenciais. Ao relacionarmos a habilidade de imitação à produção verbal do Grupo TEA, verificamos relação direta entre produção de frases e imitação de esquemas sequenciais. Conclusão: Foi possível comparar a habilidade de imitação gestual e de esquema sequencial e verificar maior comprometimento de desempenho nas crianças com diagnóstico compatível com o Espectro do Autismo. Dentre estas, verificouse relação direta significativa entre a habilidade de imitação de sequências de rotinas familiares e a produção verbal de palavras e frases. .
