Take the child to a physician or therapist who will run specific gross motor tests on him. The therapist may use a recognized scale, such as the Peabody Motor Scale, also known as PDHS-2. This series of tests makes a picture of where the child's gross motor skills are in relation to others of her age. The therapist will check the reflexes in a child of 11 months or younger.
Stand the child up, as directed by the therapist. This is to check her stationary position, and involves a 30-item test. The therapist will check the child's locomotion. Babies start by lifting their heads, and then gradually their upper bodies until they can sit upright. The next step is for the child to crawl, stand and walk. The therapist will check that child's ability to move independently, according to the norm for her age.
Cooperate with the therapist when he is checking the child's object manipulation. The therapist will do this by using a ball and observing how well the child can throw, catch and kick the ball. He will then carry out a visual motor integration test. This is a 72-item test, that checks the child's visual perceptive ability. This involves some eye-hand coordination, as the child's fine and gross motor skills are closely related.
