During development, motor skill acquisition occurs in a relatively similar sequence and emerges at a consistent age range with a level of variability and clustering of skills. Deficits or disorders within the infant or child’s movement systems or elements of motor control processing can lead to motor delays. As motor development is foundational for advanced motor skills, delays could impact function and participation throughout the lifespan. The trajectory of development in infants and children with developmental delays, including motor, can be altered with early intervention and environmental exposure. Recent research has focused on the detection through testing of infants to promptly diagnose and initiate interventions, maximizing development and lifelong success. Patterns in the development of early motor skills are studied to lead to the diagnosis and intervention of DCD and other conditions in associated developmental domains. The abnormal or delayed acquisition of movement and motor milestones can be an indicator of future developmental delays in other domains and even conditions. Thus, early intervention of motor developmental delays could be far reaching in skill acquisition in the foundational skills fundamental achieving encompassing majority of life skills.
