Fine motor skills can become impaired in a variety of ways, including injury, illness, stroke , and congenital deformities. An infant or child up to age five who is not developing new fine motor skills for that age may have a developmental disability.

Children with delays in fine motor skills development have difficulty controlling their coordinated body movements, especially with the face, hands, and fingers.
