There are two types of motor functions: Gross and Fine movements.
- Gross motor skills involve large body and large muscle movements. These skills are improved with crawling, walking, jumping/leaping/skipping, going up and down stairs.
- Fine motor skills, are small, sensitive movements, mainly of the fingers, such as writing, zipping and unzipping, buttoning a shirt. These skills require systematic training and many motor skills, such as hand-eye coordination, which also appear in dysgraphia. There are numerous complex movements and strategies for planning movements that are involved in learning each activity.
