ABSTRACT The overall birth prevalence of cerebral palsy is about 2 per 1000 live births. Weakness in balance control is one of the most common problems encountered in children with CP. One of the most widely used physiotherapy approaches for children with CP is Bobath therapy. Exercise with the Bobath method can improve postural control and balance in children with CP. This study aims is to determine the effect of exercise therapy with the Bobath method for balance in a child with spastic diplegic cerebral palsy. This study using a single-subject research conducted on a child with a diagnosis of spastic diplegic cerebral palsy who was given exercise therapy using the Bobath method 4 times a week for 4 weeks. Measurement of balance using the Pediatric Balance Scale (PBS) which was carried out before exercise therapy was given (A1), follow-up (A2), and evaluation of the final outcome (A3). The results showed that the patient had an increase in the PBS score, which means that there was an increase in functional balance. The conclusion of this study is that exercise therapy with the Bobath method which has been carried out 4 times a week for 4 weeks improves functional balance in a child with a diagnosis of spastic diplegic cerebral palsy.
