Developmental Medicine and Child Neurology published research on visual motor deficits in very preterm children. There were 58 very preterm children (average age 7 yr 6 months and average gestational age 29.2 weeks) and 64 age matched full term children in the study. The participants IQ was measured and a diagnosis of developmental coordination disorder (DCD) was given if the child scored below the 15th percentile on the Movement Assessment Battery for Children. The children traced a trail on a touch screen using their index finger to evaluation visual motor performance. In one condition the children traced a predictable path and in the other condition it was an unpredictable or unstructured path.
The results indicated the following:
- 46% of the very preterm children received a diagnosis of DCD compared to 16% of the full term children
- in the predictable path condition there was no difference in visual motor performance between the very preterm and full term children
- in the non structured path condition the very preterm children had poorer visual motor performance whether DCD was present or not
The researchers concluded that the predictability of a visual motor task plays a crucial role in very preterm children with DCD and without DCD.
