If a child has difficulty in using large muscle groups, this is called a gross motor disability. Difficulty in performing tasks that require many muscles to work together in an integrated way is called a fine motor disability. Gross motor disabilities can cause your child to be clumsy, to stumble, to fall, to bump into things, or to have trouble with generalized physical activities like running, climbing, or swimming. The most common form of fine motor disability shows up when the child begins to write. The problem lies in an inability to get the many muscles in the dominant hand to work together as a team.
Writing requires a constant flow of such activities.
Now place your pen in your nondominant hand and try to write. If you go very slowly, it is tedious but your handwriting is legible. If you go at a regular pace, however, your hand aches and your handwriting deteriorates immediately. A child with fine motor disability goes through this all the time. When a child has a visual perceptual problem, the brain, which has incorrectly recorded or processed information, will probably misinform the muscles during activities that require eye-hand coordination.
