Insights

Children born very preterm at risk for developmental coordination disorder (DCD) exhibit poorer gait performance, particularly during dual-task walking. Early identification of these gait deficits is crucial for intervention.

Area of Science:

  • Developmental Pediatrics
  • Neurology
  • Gait Analysis

Background:

  • Children born very preterm often display gait impairments compared to full-term peers.
  • Identifying very preterm children at risk for developmental coordination disorder (DCD) is essential for early intervention.
  • Gait deficits in very preterm children are more pronounced during dual-task walking.

Purpose of the Study:

  • To compare spatiotemporal gait variables between preschool-age children born very preterm at risk for DCD and those not at risk.
  • To identify specific gait parameters that differentiate very preterm children with and without DCD risk.
  • To investigate gait performance under various conditions, including preferred speed, cognitive dual-task, motor dual-task, and tandem walking.

Main Methods:

  • Participants included preschool-age children born < 30 weeks' gestation.
  • Risk for DCD was defined using the Movement Assessment Battery for Children-Second Edition (≤16th percentile), Wechsler Preschool and Primary Scale of Intelligence-Fourth Edition (≥80), and absence of cerebral palsy.
  • Spatiotemporal gait variables were assessed using GAITRite® during preferred speed, dual-task, and tandem conditions.

Main Results:

  • No significant differences in most gait variables were observed during preferred speed walking between groups.
  • Children at risk for DCD exhibited a wider base of support (BOS) and shorter single support time during motor dual-tasking.
  • Wider BOS and higher cadence were noted in children at risk for DCD during tandem walking.

Conclusions:

  • Preschool-age children born very preterm and at risk for DCD demonstrate poorer walking performance, especially in dual-task situations.
  • Complex gait assessments may aid clinicians in detecting subtle gait impairments in at-risk children.
  • Further research is warranted to explore the impact of gait variability on daily function and sports participation in this population.

Nature and Nurture

Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience, such as differences...

Longitudinal Research

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses a challenge in...
