The purpose of this study is to examine the effects of eye movement through postural control on cerebral palsy children’s occulomotor ability and visual motor coordination function. The survey was conducted targeting three cerebral palsy children in a children’s development institute. This study investigated the general characteristics of the subjects with a 3-week intervention period consisting of gross motor key point control for 60 minutes at a time, four times a week. Then the researchers conducted a single-subject experimental A-B design for one week after a 3 week-therapeutic intervention to compare the effects of therapy intervention. The result of the study are as follows. First, it turns out that eye movement through postural control has a positive effect on cerebral palsy children’s gross motor functional classification system. Second, the results indicate that visual motor coordination function through postural control influences positively on cerebral palsy children’s gross motor functional classifical system. The study concludes that eye movement through postural control has an effect on the improvement of gross motor functional classification system measurement for three cerebral palsy children, and moreover affects positively cerebral palsy children’s visual motor coordination function.
