DEFINITION

DEVELOPMENTAL COORDINATION DISORDER (DCD) is a neurodevelopmental disorder characterized by significant impairment in the acquisition, execution, coordination, planning, and refinement of motor skills that substantially interferes with daily activities, academic performance, occupational functioning, recreational participation, and age-appropriate independence.

Individuals with DCD demonstrate difficulties with motor planning (praxis), balance, coordination, timing, sequencing, spatial organization of movement, fine motor control, and complex motor learning. Symptoms are not fully explained by intellectual disability, neurological disease, muscular disorders, or sensory impairment.

Within the SCF-RDOS framework, Developmental Coordination Disorder is conceptualized as a developmental sensorimotor integration disorder involving dysfunction across motor-planning networks, cerebellar coordination systems, executive-motor integration pathways, proprioceptive processing architecture, motor-learning circuits, and adaptive movement-regulation systems.
