Cognitive and Postural Activities of Prematurely Born Children

France48 participantsStarted 2020-09-11

Plain-language summary

Prematurely born children (PC) have academic difficulties related to poorer attention capabilities. Additionally, they often show excessive mobility, quoted as agitation. Some consider it could be related to poorer postural control and impaired perception of gravity vertical. But, this excessive mobility could also be an unconscious way for PC to improve their attention performance. The aim of this study is to evaluate the interdependence between postural and cognitive activities in school age PC versus term born children (TC). First, the performance of PC and TC at the Attention Network Test for Children will be analyzed with the use of a mobile versus a classic school chair. Secondly, participants will have to position a stick vertically to measure their perception of vertical gravity. Finally, the spontaneous postural activity of PC and TC (evaluated by the center of pressure displacement) will be studied during the execution of three different attention tasks at different levels of difficulty. Success rate and reaction time will be analyzed for all attention tasks. Moreover, center of pressure displacement calculation will allow evaluation of infants' spontaneous mobility, the precision of their postural control and the attention allocated to their posture.

Inclusion Criteria: * Children born before 37 weeks gestation or at term and routinely followed for their prematurity in the follow-up clinic of the Maternite Regionale Universitaire and healthy term born children recruited after information in different schools of Meurthe-et-Moselle * Child whose holders of parental authority have received complete information on the organization of the research and have signed the consent Exclusion Criteria: * Severe hypotrophy at birth defined by a weight z-score below -2. * Children with developmental, cognitive, visual or motor disability preventing the execution of the tests

What they're measuring

Accuracy and Reaction time (in msec) to the response to visual target (fish) direction

Timeframe: 8 minutes

Angle error (in degree) between the stick orientation given by the child and the real vertical

Timeframe: 4 minutes 30 secondes

Sway path (distance traveled by the center of pressure - CP -) and surface area (ellipse covering 90% of the center of pressure displacement)

Timeframe: 4 minutes 30 secondes

Sway path (distance traveled by the center of pressure - CP -), surface area (ellipse covering 90% of the center of pressure displacement) and entropy (index of regularity of postural oscillations)

Timeframe: 12 minutes
