Motor skills and genetic markers in children with specific language impairment and typical language development

The objective of the study was to analyze the Dermatoglyphic and Motor characteristics in children with specific mixed language disorder (TEL-m) and typical language development (DTL). The research design was non-experimental descriptive, comparative and transversal. The sample consisted of 60 children aged 5 to 6 years and 11 months old. The Childhood Learning and Development Test (TADI) and the Cummings and Midlo Protocol (1961) were used to evaluate the dermatoglyphic characteristics. The results indicate that children with TEL-m obtained a T-score of 44.8 and children with DTL a T-score of 58.8 points and that the most frequent design was Presilha (L) 64% in children with TEL-m and 66% in children with DTL. In addition, significant differences are observed (p<.00) in motor skills, yet they were not significant in the Dermatoglyphic variables. For the above, we may accept that significant differences with p set at 0.5 were only evident in the motor area in children with TEL-m and DTL.
