Thus, when a child presents with a chief complaint of delays in motor development, a thorough developmental history is needed to uncover possibly more subtle delays in language, nonverbal/visual-motor problem-solving, social, or adaptive development. However, there is a spectrum of dissociated and deviated motor development, where motor development is discrepantly delayed compared to other domains in development, and in more severe cases, where motor skills are acquired in a developmentally deviated manner (see Chapter 83). This chapter will review the motor disabilities contained within this spectrum of discrepant (or dissociated and deviated) motor delay.
