This study examined the effects of group exercise program on health conditions and quality of life in cerebral palsy. Adults with cerebral palsy in their 20’s who participated in the evaluation of measurement tools prior to and following the experiment. The control group was engaged in manual exercise for the range of joint movement and extension exercise for arms, legs and trunk, and experimental group performed group exercise program including boccia exercise. The health condition and quality of life of the experimental group were significantly increased after intervention (.05<). There was a slight increase in the control group, however it was not statistically significant. As a result of comparing the health condition and quality of life of the two groups, the value of the experimental group was significantly higher than that of the control group. The results of this study suggest that exercise programs for patients with cerebral palsy in the twenties are considered as beneficial interventions to improve health conditions and quality of life.
