Objectives <p>The aim of this research was to investigate the developmental pattern of motor behaviors that have the potential to alert clinical concern in children who have a history of early medical risk and present with low motor performance but who do not meet the threshold of developmental coordination disorder (DCD).</p> Methods <p>Groups of participants with a history of early medical risk who presented with low or normal motor performance participated in tasks with increasing attentional complexity, using a computer-based attention task, and an assessment of walking in singular and dual tasks with increasing demands.</p> Results <p>Analysis of computerized attention task data by motor performance group, age, and task revealed that the low motor performance group did not demonstrate developmental improvement in one of the tasks, whereas the normal motor performance group did (<i>F</i>(1, 22) = 4.211, <i>p</i> = 0.05, <i>h</i>^<i>2</i>_<i>p</i> = 0.161). The low motor performance group also exhibited more exaggerated compensatory balance reactions than the normal motor performance group, including elbow flexion (<i>F</i>(2, 28.48) = 5.473, <i>p</i> = 0.011, <i>h</i>^<i>2</i>_<i>p</i> = 0.267) as well as trunk deviation (<i>F</i>(1, 19) = 5.522, <i>p</i> = 0.03, <i>h</i>^<i>2</i>_<i>p</i> = 0.225).</p> Conclusions <p>These results highlight a group of children who may benefit from more clinical attention despite being subthreshold for neurodevelopmental diagnosis.</p>
