Which statement best reflects internal processing deficits related to predictive control and sensory feedback in DCD?

• A. Impaired executive function
• B. Deficient integration of predictive control and sensory feedback
• C. Variances in activation patterns during motor tasks
• D. Differences in white matter architecture - CST, corpus callosum

Answer: (B)

Internal motor control relies on predicting what will happen when you move and then using sensory feedback to adjust that prediction. The brain uses a forward model to anticipate the sensory consequences of a motor command, and it compares those predictions with actual sensory input to make online corrections. In developmental coordination disorder, the processing deficit is most clearly described as a problem with integrating these predictive signals with sensory feedback. When this integration is deficient, movement planning and online adjustments are less accurate, especially for new or complex tasks, leading to clumsy, slow, or poorly coordinated actions. Children may rely more on visual guidance because proprioceptive and predictive cues aren’t being combined effectively, which fits the idea of impaired integration of predictive control and sensory feedback.

Other options point to related but distinct ideas (executive function, neural activation patterns, or white matter differences) rather than the specific integration process underlying predictive control and sensory feedback.
