“…1 There is preliminary evidence of abnormalities in eye movement in children with coordination difficulties and in children who have been premature, when compared with control subjects. 44 Our study group had a high prevalence (35%) of abnormalities in smooth pursuit, saccadic eye movements, and/or vergence. Normal eye movements and coordination may be closely related in the functional coupling between perception and action.…”

“…It was shown in very preterm infants that reduced occipital cortical volumes at term equivalent age were associated with poor visual motion perception at 2 y of age (29). Abnormal visual tracking ability is present in many behavioral and psychiatric disorders, such as autism, attention deficit hyperactivity disorder, developmental coordination disorders, and dyslexia (3,4,10,26,30), which also constitute a risk for children born very preterm. Visual tracking assessments and longitudinal follow-up studies may contribute to an increased understanding of the relation between neurodevelopmental profiles, and behavioral and psychiatric disorders in these children.…”

Background: Typically developing infants track moving objects with eye and head movements in a smooth and predictive way at 4 mo of age, but this ability is delayed in very preterm infants. We hypothesized that visual tracking ability in very preterm infants predicts later neurodevelopment. Method: In 67 very preterm infants (gestational age<32 wk), eye and head movements were assessed at 4 mo corrected age while the infant tracked a moving object. Gaze gain, smooth pursuit, head movements, and timing of gaze relative the object were analyzed off line. Results of the five subscales included in the Bayley Scales of Infant Development (BSID-III) at 3 y of age were evaluated in relation to the visual tracking data and to perinatal risk factors. results: Significant correlations were obtained between gaze gain and cognition, receptive and expressive language, and fine motor function, respectively, also after controlling for gestational age, severe brain damage, retinopathy of prematurity, and bronchopulmonary dysplasia. conclusion: This is the first study demonstrating that the basic ability to visually track a moving object at 4 mo robustly predicts neurodevelopment at 3 y of age in children born very preterm.

“…Indeed, this task requires that children visually judge the orientation of objects on the basis of visual exploration of the page. Langaas et al (1998) suggested that oculomotor control disorders could be the expression of an overall deficit of motor coordination (involving different effectors), rather than the cause of these difficulties. This assumption, which has to be verified, sustains the debate since it was established that motor difficulties related to optic ataxia in adults must be differentiated from apraxia (Goldenberg, 2009).…”

Nature and Specificity of Gestural Disorder in Children with Developmental Coordination Disorder: A Multiple Case Study

et al. 2017

Aim: Praxis assessment in children with developmental coordination disorder (DCD) is usually based on tests of adult apraxia, by comparing across types of gestures and input modalities. However, the cognitive models of adult praxis processing are rarely used in a comprehensive and critical interpretation. These models generally involve two systems: a conceptual system and a production system. Heterogeneity of deficits is consistently reported in DCD, involving other cognitive skills such as executive or visual-perceptual and visuospatial functions. Surprisingly, few researches examined the impact of these functions in gestural production. Our study aimed at discussing the nature and specificity of the gestural deficit in DCD using a multiple case study approach.Method: Tasks were selected and adapted from protocols proposed in adult apraxia, in order to enable a comprehensive assessment of gestures. This included conceptual tasks (knowledge about tool functions and actions; recognition of gestures), representational (transitive, intransitive), and non-representational gestures (imitation of meaningless postures). We realized an additional assessment of constructional abilities and other cognitive domains (executive functions, visual-perceptual and visuospatial functions). Data from 27 patients diagnosed with DCD were collected. Neuropsychological profiles were classified using an inferential clinical analysis based on the modified t-test, by comparison with 100 typically developing children divided into five age groups (from 7 to 13 years old).Results: Among the 27 DCD patients, we first classified profiles that are characterized by impairment in tasks assessing perceptual visual or visuospatial skills (n = 8). Patients with a weakness in executive functions (n = 6) were then identified, followed by those with an impaired performance in conceptual knowledge tasks (n = 4). Among the nine remaining patients, six could be classified as having a visual spatial/visual constructional dyspraxia. Gestural production deficits were variable between and within profiles.Discussion: This study confirmed the heterogeneity of gestural production deficit among children with a diagnosis of DCD, at both intra- and inter-individual levels. The contribution of other cognitive deficits in most of the profiles allows discussing the specificity of gestural difficulties. This argues in favor of the necessity to distinguish gestural problems with other deficits made apparent through gesture.
