Physiologic Data

Abstract Although certain speech development milestones are readily observable, the developmental course of speech motor control is largely unknown. However, recent advances in facial motion tracking systems have been used to investigate articulator movements in children and the findings from these studies are being used to further our understanding of the physiologic basis of typical and disordered speech development. Physiologic work has revealed that the emergence of speech is highly dependent on the lack of flexibility in the early oromotor system. It also has been determined that the progression of speech motor development is non-linear, a finding that has motivated researchers to investigate how variables such as oromotor control, cognition, and linguistic factors affect speech development in the form of catalysts and constraints. Physiologic data are also being used to determine if non-speech oromotor behaviors play a role in the development of speech. This improved understanding of the physiology underlying speech, as well as the factors influencing its progression, helps inform our understanding of speech motor control in children with disordered speech and provide a framework for theory-driven therapeutic approaches to treatment.

The article presents a holistic view on neuroosteopathy. It demonstrates the connection between the congenital and the acquired alterations with due regard to the epigenetic aspects of morphogenesis in different periods of the organism’s individual development. On the basis of the analysis of scientific literature and of the clinical osteopathic experience the connection between the child’s motor development and the formation of his nervous system is shown. The article presents a plan of osteopathic treatment of the lesions diagnosed which is based on the analysis of the connection between the motor acts, gestures, positions and congenital reflexes.

BackgroundEarly developmental milestones, such as the age at first walking or talking, are associated with later diagnoses of neurodevelopmental disorders, but the relationship to genetic risk for neurodevelopmental disorders are unknown. Here, we investigate associations between genetic liability to autism spectrum disorder (autism), attention deficit hyperactivity disorder (ADHD), and schizophrenia and attainment of early-life language and motor development milestones.MethodsWe use data from a genotyped sub-set (N = 15 205) of children in the Norwegian Mother, Father and Child Cohort Study (MoBa). In this sample, we calculate polygenic scores for autism; ADHD and schizophrenia and predict maternal reports of children’s age at first walking and talking, motor delays at 18 months, language delays at 3 years, and a generalized measure of concerns about development. We use linear and probit regression models in a multi-group framework to test for sex differences.ResultsADHD polygenic scores predicted earlier walking age in both males and females (β=-0.037, pFDR=0.001), and earlier first use of sentences (β=-0.087, pFDR=0.032) but delayed language development at 3 years in females only (β=0.194, pFDR=0.001). Additionally, we found evidence that autism polygenic scores were associated with later walking (β=0.027, pFDR=0.024) and motor delays at 18 months (β = 0.065, pFDR=0.028). Schizophrenia polygenic scores were associated with a measure of general concerns about development at 3 years in females only (β=0.132, pFDR=0.024).ConclusionsGenetic liabilities for neurodevelopmental disorders show some specific associations with measures of early motor and language development in the general population, including the age at which children first walk and talk. Associations are generally small and occasionally in unexpected directions. Sex differences are evident in some instances, but clear patterns across different polygenic scores and outcomes are hard to discern. These findings suggest that genetic susceptibility for neurodevelopmental disorders is manifested in the timing of developmental milestones in infancy.
