Postural responses to a moving room in children with and without developmental coordination disorder.

Chung et al. (2011) watched kids stand in a small room. The walls slid back and forth.

Some kids had developmental coordination disorder. Some kids were typical.

The team changed how fast and how far the walls moved. They tracked how much each child swayed.

Kids with DCD swayed differently. Their bodies followed the wall motion more than typical kids.

The difference showed up only at certain speeds and distances. At other settings, the groups looked the same.

Spanoudis et al. (2011) ran a similar lab test. They gave kids a hard picture task while standing. Typical kids stiffened and swayed less. Kids with DCD swayed more. Both papers show the same big idea: visual load changes balance in DCD, but the direction depends on the task.

Godoi-Jacomassi et al. (2025) used newer sway math. They found bigger CoP spread and more tiny corrections in DCD. Their tools split the problem into "bad prediction" versus "bad sensory use." This finer picture builds on Chae’s first look.

Velghe et al. (2025) pooled every postural training study. Training helps, but no single method wins. Because vision matters so much, they say to mix visual challenges into balance drills. Chae’s room-on-wheels test is one clear way to do that.

Check balance while the room or the task moves, not just while the child stands still. Start with slow wall motion or a light visual task. Watch sway change. If it spikes, you have found a visual weighting issue. Add graded visual motion to your balance goals. This gives you a clear, measurable step between static stance and real play settings.
