The purpose of this study is to identify influence that eye movement have an effect on postural control and balance performance by plegia side of the impaired patients of central nervous system. Subjects are patients with the impairment of central nervous system and experimental and control groups are forty people and thirty people seperatively, Total subjects were selected to seventy persons, but twelve persons of experimental group quit during the experimental periods and eight persons of control group did not measure after exercise. Therefore, twenty eight persons of experimental group and twenty two persons of control group were selected in this study and experimental group peformed eye movement for eight weeks according to the exercise program of this study. The measurement of dependent variable is right static balance, left static balance, bilateral static balance, and bilateral dynamic balance before exercise and after eighth week of exercise, examiner again measured and analyzed the results. The results were as follows: 1. As the result of comparing balance performance ability after test of the experimental and control group with right hemiplegia and control group, all of static balance performance ability of right side (p < 0.01), static balance performance ability of left side (p < 0.01), static balance performance ability of bilateral side(p < 0.01), dynamic balance performance ability of bilateral side(p < 0.05) of experimental group were statistically greater improved than those of the control group. 2. As the result of comparing balance performance ability after test of the experimental and control group with left hemiplegia and control group, all of static balance performance ability of right side (p < 0.01), static balance performance ability of left side (p < 0.01), static balance performance ability of bilateral side(p < 0.05), dynamic balance performance ability of bilateral side(p < 0.05) of experimental group were statistically greater improved than those of the control group.
